Description

Die vorliegende Erfindung betrifft ein Absorberelement für die Wärme- und/oder Schalldämmung, bestehend aus einem faserförmigen Dämmmaterial und einem flächig ausgebildeten Ummantelungsmaterial, mit welchem das faserförmige Dämmmaterial ummantelt ist sowie ein Verfahren zur Herstellung eines Absorberelementes, aufweisend die Verfahrensschritte, Bereitstellen eines Trägermaterials, Aufbringen eines faserförmigen Dämmmaterials auf das Trägermaterial, Abdecken des auf das Trägermaterial aufgebrachten Dämmmaterials mit einem Abdeckmaterial, Verbinden des Abdeckmaterials mit dem Trägermaterial zur Ausbildung eines das Dämmmaterial enthaltenden Beutels, wobei ein Trägermaterial mit von dem Abdeckmaterial unterschiedlichen Eigenschaften verwendet wird.The present invention relates to an absorber element for thermal and / or acoustic insulation, consisting of a fibrous insulating material and a flat covering material, with which the fibrous insulating material is encased, and a method for producing an absorber element, comprising the method steps, providing a carrier material, application a fibrous insulating material on the carrier material, covering the insulating material applied to the carrier material with a covering material, connecting the covering material to the carrier material to form a bag containing the insulating material, a carrier material having properties different from the covering material being used.

Zur Wärme- und/oder Schalldämmung werden Wände und/oder Decken von Gebäuden mit geeigneten Dämmmaterialien versehen. Hierbei gelangen vielfach faserartige Produkte wie Mineralwollefasern zum Einsatz. Die aus Schmelzen entsprechender Rohstoffe durch Spinnen hergestellten Fasern werden zur Anwendung als Wärme- oder Schalldämmmaterial gegebenenfalls durch den Zusatz geeigneter Bindemittel zu einem Vlies verarbeitet, welches zu Dämmstoffplatten oder -matten verarbeitet werden kann.For heat and / or sound insulation, walls and / or ceilings of buildings are provided with suitable insulation materials. Fiber-like products such as mineral wool fibers are often used here. The fibers produced from the melting of corresponding raw materials by spinning are processed for use as heat or sound insulation material, optionally by adding suitable binders, to form a nonwoven which can be processed to give insulation boards or mats.

Das so erhaltene Material lässt sich in vorteilhafter Weise sowohl zur Schalldämmung als auch zur Wärmedämmung einsetzen.The material obtained in this way can advantageously be used both for sound insulation and for thermal insulation.

In Räumen, in denen nutzungsbedingt Schallbelastungen auftreten, werden vielfach zur Geräuschdämmung sogenannte Absorber eingesetzt, welche die Schallbelastung reduzieren. Als Absorber werden Vorrichtungen bezeichnet, die die in den Schallwellen enthaltene Energie in Wärmeenergie umwandeln. Mineralwolle, beispielsweise Stein- und/oder Glaswolle sind vorzugsweise verwendete Materialien zur Herstellung solcher Absorber. Die genannten Materialien haben die Eigenschaft, schalloffen zu sein.In rooms in which sound pollution occurs due to usage, so-called absorbers are often used for noise insulation, which reduce the noise pollution. Devices are referred to as absorbers that convert the energy contained in the sound waves into thermal energy. Mineral wool, for example stone and / or glass wool, are preferably used materials for producing such absorbers. The materials mentioned have the property of being open to sound.

Die Absorber können entweder sichtbar als Wand- oder Deckenabsorber angebracht sein oder nicht sichtbar in Bauteile integriert sein. In der ersten Variante als sichtbare Wand- oder Deckenabsorber werden beispielsweise vlieskaschierte Mineralwollplatten in Rahmen eingebracht und als sogenannte "Baffle" von der Decke abgehängt oder an der Wand befestigt.The absorbers can either be attached visibly as wall or ceiling absorbers or integrated invisibly into components. In the first variant as visible wall or ceiling absorber, for example, fleece-laminated mineral wool panels are placed in frames and suspended from the ceiling as so-called "baffle" or fastened to the wall.

Eine Alternative sind abgehängte Deckensysteme, jedoch unter der Voraussetzung, dass sie ausreichend schalloffen sind. Für solche Systeme eignen sich insbesondere Glas- oder Steinwolleplatten, die mit dekorativen Vliesen versehen sind und in abgehängte, standarisierte Schienen und Rahmen eingelegt oder direkt unter der Decke angebracht werden können.Suspended ceiling systems are an alternative, provided that they are sufficiently sound-open. For such systems, glass or rock wool panels are particularly suitable, which are provided with decorative nonwovens and can be inserted in suspended, standardized rails and frames or attached directly under the ceiling.

Es hat sich jedoch herausgestellt, dass aus Gründen des Designs, der Optik oder wegen der benötigten sehr widerstandsfähigen Oberflächen die vorgenannten Systeme nicht anwendbar sind. Wünscht der Architekt oder Bauherr beispielsweise eine Metalldecke oder soll die Wand einer Werkhalle mit Trapezprofilen verkleidet werden, sind die zuvor genannten Systeme in der Regel nicht anwendbar.However, it has been found that the aforementioned systems cannot be used for reasons of design, optics or because of the very resistant surfaces required. If the architect or client wants a metal ceiling, for example, or if the wall of a workshop is to be clad with trapezoidal profiles, the systems mentioned above are generally not applicable.

Geschlossene Metalloberflächen sind im Regelfall schallhart und tragen daher nicht zur Schallabsorption bei. Um bei den gewählten Materialien ein Eindringen der Schallwellen sicherstellen zu können, werden die Oberflächen häufig mit Perforierungen versehen. Hierbei ist es aus dem Stand der Technik sowohl bekannt, mikroperforierte Systeme anzuwenden, welche über eine Vielzahl von Perforierungen mit kleinstem Durchmesser eine große Fläche erzeugen, die zum Abbau der Schallenergie beiträgt, als auch Systeme mit größeren Durchmessern der Perforierung einzusetzen, wobei die Schallwellen durch die Perforierung eindringen und dann in einem, hinter beispielsweise dem Metall angebrachten Absorber abgebaut werden.Closed metal surfaces are generally sound-resistant and therefore do not contribute to sound absorption. In order to ensure that the sound waves penetrate the selected materials, the surfaces are often perforated. It is known from the prior art both to use microperforated systems which produce a large area over a multiplicity of perforations with the smallest diameter, which contributes to the reduction of the sound energy, and to use systems with larger diameters of the perforation, the sound waves passing through penetrate the perforation and then be dismantled in an absorber attached behind, for example, the metal.

Perforierte Metalldecken aus Stahlblech oder Leichtmetallkonstruktionen wie Aluminium werden ebenfalls mit vlieskaschierten Absorbern ausgerüstet, wobei die Vlieskaschierung auf der Metalldecke aufliegt.Perforated metal ceilings made of sheet steel or light metal constructions such as aluminum are also equipped with fleece-lined absorbers, whereby the fleece lamination rests on the metal ceiling.

Bei den heute verwendeten Absorbern handelt es sich im Regelfall um Mineralwolle, die in Polyethylen (PE-Folie), wegen der Optik häufig in schwarzer Farbe, eingeschweißt ist. Unter dem Begriff Mineralwolle sind hierbei Glaswolle, Steinwolle und Schlackenwolle zu subsumieren.The absorbers used today are usually mineral wool, which is welded into polyethylene (PE film), often in black because of its appearance. Glass wool, rock wool and slag wool are subsumed under the term mineral wool.

Durch das Einschweißen in PE-Folie wird das Herausrieseln von Fasern ebenso verhindert, wie das "Herauswaschen" auf der Rückseite oder den Kanten, falls der oberhalb der abgehängten Decke vorhandene Raum zur Luftführung genutzt wird.Welding in PE film prevents fibers from trickling out as well as "washing out" on the back or the edges if the space above the suspended ceiling is used for airflow.

Eine Alternative, bei der vorder- und rückseitig vlieskaschierte Mineralwollprodukte Verwendung finden, deren Kanten dann ebenfalls mit Vliesen kaschiert sind, ist teuer, da die Seiten nur schwierig mit Vlies beschichtet werden können. Im Regelfall reißen diese Stellen wieder auf und es können Mineralwollfasern in die Luft gelangen.An alternative in which mineral wool products laminated on the front and back are used, the edges of which are then also laminated with fleeces, is expensive since the sides can only be coated with fleece with difficulty. As a rule, these areas tear open and mineral wool fibers can get into the air.

Das Einschweißen in Polyethylen-Folie hat sich als marktübliche und gängige Variante zwischenzeitlich durchgesetzt. Die Klassifizierung von Bauprodukten und Bauarten zu ihrem Brandverhalten erfolgt nach der Norm DIN EN 13501-1. Diese unterscheidet zwischen homogenen und nicht homogenen Bauprodukten. Absorberelemente auf Basis eines aus Polyethylen-Folie gebildeten Beutels (Polybeutel) sind nicht homogene Bauprodukte, da sie aus mehr als einem Bestandteil bestehen.In the meantime, welding in polyethylene film has become established as a common and common variant. The classification of construction products and types according to their fire behavior is based on the standard DIN EN 13501-1. This differentiates between homogeneous and non-homogeneous construction products. Absorber elements based on a bag made of polyethylene film (poly bag) are not homogeneous construction products because they consist of more than one component.

Homogene und nicht homogene Bauprodukte werden gemäß der genannten Norm in unterschiedliche Brandschutzklassen eingeteilt, wobei die höchste Brandschutzklasse die Klasse A1 ist.Homogeneous and non-homogeneous construction products are divided into different fire protection classes according to the standard mentioned, the highest fire protection class being class A1.

Für den Einsatz von Baustoffen in bestimmten Bereichen der Bautechnik ist zwingend die Verwendung von Baustoffen bestimmter Brandklassifizierungen vorgesehen.For the use of building materials in certain areas of construction technology, the use of building materials with certain fire classifications is mandatory.

Bisher sind aus dem Stand der Technik keine folienkaschierten, also mit entsprechenden Kunststofffolien ummantelte Absorberelemente bekannt, welche zumindest der Brandschutzklasse A2 genügen. Vielfach ist jedoch für den Einbau entsprechender Materialien insbesondere im Bereich der öffentlichen Gebäude eine Brandschutzklassifizierung der Klasse A2 zwingend vorgeschrieben.So far, no foil-clad absorber elements are known from the prior art, that is to say coated with appropriate plastic foils, which at least meet fire protection class A2. In many cases, however, a fire protection classification of class A2 is mandatory for the installation of appropriate materials, especially in the area of public buildings.

Für die Herstellung folieneingeschweißter Absorber werden im Regelfall Polyethylen- oder Polypropylenschläuche oder alternativ -halbschläuche verwendet. Im Herstellungsprozess dieser Absorber werden die Schläuche an der einen Seite durch geeignete Einrichtungen wie beispielsweise Schweißbalken verschlossen. In den so entstandenen Beutel werden die auf Maß konfektionierten Dämmwollzuschnitte eingeschoben und das offene Ende wird wiederum verschweißt. Der so entstandene allseitig geschlossene Beutel wird dann vom Endlosfolienschlauch abgetrennt. Alternativ wird bei Verwendung von Halbschläuchen der Dämmstoffzuschnitt auf eine Folienhälfte gelegt, die andere Folienhälfte übergeschlagen und anschließend an den offenen Enden verschweißt.Polyethylene or polypropylene hoses or, alternatively, half-hoses are generally used for the production of film-welded absorbers. In the manufacturing process of these absorbers, the hoses are closed on one side by suitable devices such as welding bars. The tailor-made insulation wool blanks are inserted into the resulting bag and the open end is welded again. The resulting bag, which is closed on all sides, is then separated from the continuous film tube. Alternatively, when using half hoses, the insulation blank is placed on one half of the film, the other half of the film is folded over and then welded at the open ends.

Die so hergestellten Absorber weisen neben einer schlechten Brandschutzklassifizierung weitere maßgebliche Nachteile auf. So wird beispielsweise eine Vielzahl von unterschiedlichen Abmessungen der Folienschläuche benötigt, um Beutel unterschiedlicher Abmessungen bereitzustellen. Darüber hinaus muss die Wandstärke der Folie möglichst dünn gehalten werden, um die schallabsorbierenden Eigenschaften nicht nachteilig zu beeinflussen. Andererseits muss die Wandstärke des eingesetzten Folienschlauchs hinreichend dick sein, um die notwendige Widerstandsfähigkeit gegen mechanische Beschädigungen zu bieten. Dies führt zu einem schlecht zu lösenden Widerspruch, da einerseits eine mechanisch stabile Folie schalldämmtechnische Mängel mit sich bringt und andererseits ein offenporiges Vlies oder eine deutlich dünnere Folie mechanisch nicht widerstandsfähig genug sind, um auf der mechanisch belasteten Seite ein Austragen der Mineralwollefasern zu verhindern.In addition to poor fire protection classification, the absorbers produced in this way have other significant disadvantages. For example, a large number of different dimensions of the film tubes are required in order to provide bags of different dimensions. In addition, the wall thickness of the film must be kept as thin as possible so as not to adversely affect the sound-absorbing properties. On the other hand, the wall thickness of the film tube used must be sufficiently thick to offer the necessary resistance to mechanical damage. This leads to a contradiction which is difficult to resolve, since on the one hand a mechanically stable film has defects in sound insulation brings and on the other hand an open-pore fleece or a significantly thinner film are not mechanically resistant enough to prevent the mineral wool fibers from being carried away on the mechanically stressed side.

Weiter nachteilig ist, dass vielfach die Folienschlauch- und Mineralwoll-Abmessung nicht exakt aufeinander abgestimmt ist, wodurch Folie übersteht, welche dann bei der Verwendung auf der Baustelle durch das Hantieren beschädigt werden kann.Another disadvantage is that the film tube and mineral wool dimensions are often not exactly matched, which means that film protrudes, which can then be damaged by handling when used on the construction site.

Die GB 2 405 415 A offenbart eine Ummantelung mit mehreren Bestandteilen, unter anderem mit einer metallisierenden Schicht. Es wird die Ummantelung beschrieben, die über ein Emissionsgrad definiert ist und eine schlechte Performance beim Einwirken von Feuer aufweist, so dass ein Flammschutzmittel zur Erzielung eines akzeptablen Brandschutzergebnisses erforderlich ist. Weiterhin offenbart der Stand der Technik lediglich eine Dichte für ein Absorberelement insgesamt, nicht jedoch für die einzelnen Komponenten.The GB 2 405 415 A discloses a casing with several components, including a metallizing layer. The cladding is described, which is defined by an emissivity and has poor performance when exposed to fire, so that a flame retardant is required to achieve an acceptable fire protection result. Furthermore, the prior art only discloses a density for an absorber element as a whole, but not for the individual components.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Absorberelement für die Wärme- und/oder Schalldämmung anzugeben, welches die aus dem Stand der Technik bekannten und zuvor genannten Nachteile zu überwinden vermag und wenigstens eine Brandschutzklassifizierung der Klasse A2 erreicht. Darüber hinaus ist es die Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung eines solchen Absorberelementes anzugeben.On the basis of this prior art, the object of the invention is to provide an absorber element for thermal and / or acoustic insulation which can overcome the disadvantages known from the prior art and mentioned above and at least achieve a fire protection classification of class A2. In addition, it is the object of the present invention to provide a method for producing such an absorber element.

Hinsichtlich des Absorberelementes wird die Aufgabe der Erfindung durch ein Absorberelement für die Wärme- und/oder Schalldämmung gelöst, bestehend aus einem faserförmigen Dämmmaterial und einem flächig ausgebildeten Ummantelungsmaterial, bei welchem das faserförmige Dämmmaterial ein Flächengewicht von 0,1 bis 6,0 kg/m2 aufweist, und das flächig ausgebildete Ummantelungsmaterial ein Flächengewicht von 0,01 bis 0,17 kg/m2 bei einem Brennwert pro Masse von 0 bis 48 MJ/kg und einem Brennwert pro Fläche von 0 bis 4,0 MJ/m2 aufweist, bei welchem das Absorberelement einen aus den Brennwerten des faserförmigen Dämmmaterials und des flächig ausgebildeten Ummantelungsmaterials gebildeten Gesamtbrennwert PCS ≤ 3,0 MJ/kg, insbesondere ≤ 2,0 MJ/kg aufweist und bei welchem die Rohdichte des Dämmmaterials zwischen 12 und 60 kg/m3 liegt.With regard to the absorber element, the object of the invention is achieved by an absorber element for thermal and / or acoustic insulation , consisting of a fibrous insulating material and a flat-shaped casing material, in which the fibrous insulating material has a basis weight of 0.1 to 6.0 kg / m 2 , and the sheet-like cladding material has a basis weight of 0.01 to 0.17 kg / m 2 with a calorific value per mass of 0 to 48 MJ / kg and a calorific value per area from 0 to 4.0 MJ / m 2 , in which the absorber element has a total calorific value PCS 3,0 3.0 MJ / kg, in particular 2,0 2.0 MJ / kg, which is formed from the calorific values of the fibrous insulating material and the sheet-like cladding material, and at which the bulk density of the insulation material is between 12 and 60 kg / m 3 .

Das in dem erfindungsgemäßen Absorberelement eingesetzte Dämmmaterial weist einen Brennwert pro Masse von 0 bis 3 MJ/kg und einen Brennwert pro Fläche von 0 bis 19,4 MJ/m2 auf.The insulation material used in the absorber element according to the invention has a calorific value per mass of 0 to 3 MJ / kg and a calorific value per area of 0 to 19.4 MJ / m 2 .

In dem erfindungsgemäßen Absorberelement kann das Ummantelungsmaterial ein Polymermaterial aufweisen.In the absorber element according to the invention, the sheathing material can have a polymer material.

In einer Ausgestaltung des erfindungsgemäßen Absorberelementes ist das Ummantelungsmaterial aus einem flächig ausgebildeten Trägermaterial und einem flächig ausgebildeten Abdeckmaterial ausgebildet, wobei das faserförmige Dämmmaterial auf das Trägermaterial aufgebracht ist und das Abdeckmaterial das faserförmige Dämmmaterial abdeckt, wobei Trägermaterial und Abdeckmaterial wenigstens entlang aller Berührungsflächen miteinander verbunden sind und so einen vollständig geschlossenen Beutel ausbilden, welcher das faserförmige Dämmmaterial aufnimmt und wobei das Trägermaterial und das Abdeckmaterial unterschiedliche Eigenschaften aufweisen können.In one embodiment of the absorber element according to the invention, the sheathing material is formed from a flat carrier material and a flat cover material, the fibrous insulating material being applied to the carrier material and the covering material covering the fibrous insulating material, the carrier material and covering material being connected to one another at least along all contact surfaces and thus form a completely closed bag, which receives the fibrous insulating material and the carrier material and the covering material can have different properties.

Als das Ummantelungsmaterial bildendes Trägermaterial und/oder Abdeckmaterial können Kunststofffolie, ein Vlies, eine Metallfolie oder ein Gewebe wie z. B. Glasfasergewebe, Metallgewebe oder Kunststoffgewebe zum Einsatz gelangen. Bei der Verwendung von Kunststofffolien haben sich insbesondere Polyethylen, Polypropylen, Polyurethan, Polyvinylchlorid oder Copolymere dieser als geeignet erwiesen. Erfindungsgemäß kann vorgesehen sein, dass Trägermaterial und Abdeckmaterial aus Kunststofffolien gebildet werden, wobei sich die Folien hinsichtlich ihrer Wandstärke unterscheiden. So kann das Trägermaterial eine schalltechnisch günstige dünne Kunststofffolie sein, wohingegen das Abdeckmaterial eine mechanisch beständige dicke Kunststofffolie sein kann. Als mechanisch beständige Kunststofffolien haben sich insbesondere Kunststofffolien wie Polyethylenfolien mit einer Stärke von ca. 40 µm erwiesen. Als schalltechnisch günstige Folien haben sich insbesondere Polyethylenfolien mit einer Folienstärke < 25 µm erwiesen. Darüber hinaus kann erfindungsgemäß vorgesehen sein, dass das Trägermaterial und/oder das Abdeckmaterial zur Verbesserung der schalltechnischen Eigenschaften perforiert oder mikroperforiert wird. Ebenso kann erfindungsgemäß eine Verstärkung des Trägermaterials und/oder des Abdeckmaterials durch geeignete Gewebe, wie z. B. Glasfasergewebe oder Metallgewebe vorgegeben sein. Darüber hinaus kann das Trägermaterial und/oder das Abdeckmaterial mit flammhemmenden Mitteln ausgerüstet sein.As the covering material forming the carrier material and / or covering material, plastic film, a fleece, a metal film or a fabric such as. B. glass fiber fabric, metal mesh or plastic mesh can be used. When using plastic films, in particular polyethylene, polypropylene, polyurethane, polyvinyl chloride or copolymers of these have proven to be suitable. According to the invention, it can be provided that the carrier material and cover material are formed from plastic films, the films differing in their wall thickness. In this way, the carrier material can be a thin that is favorable in terms of sound technology Be plastic film, whereas the cover material can be a mechanically resistant, thick plastic film. In particular, plastic films such as polyethylene films with a thickness of approximately 40 μm have proven to be mechanically resistant plastic films. Polyethylene foils with a foil thickness of <25 µm have proven to be sound-favorable foils. In addition, it can be provided according to the invention that the carrier material and / or the covering material is perforated or microperforated to improve the acoustic properties. Likewise, according to the invention, a reinforcement of the carrier material and / or of the covering material by suitable fabrics, such as, for example, B. glass fiber or metal mesh. In addition, the carrier material and / or the covering material can be equipped with flame-retardant agents.

Als Dämmmaterial können erfindungsgemäß Mineralwollefasernm sowie aus diesen Fasern hergestellte Produkte vorgesehen sein. Unter Mineralwollefasern sind Glaswollefasern, Schlackenwollefasem und/oder Steinwollefasem zu verstehen.According to the invention, mineral wool fibers and products made from these fibers can be provided as insulation material. Mineral wool fibers are to be understood as glass wool fibers, slag wool fibers and / or rock wool fibers.

Das Abdeckmaterial ist mit dem Trägermaterial wenigstens an den Berührungsstellen verklebt, vernäht, verschweißt oder zusammengeklammert. Darüber hinaus kann vorgesehen sein, dass das Abdeckmaterial mit dem Trägermaterial auch durch das Dämmmaterial hindurch mit geeigneten Mitteln verbunden ist. So kann das Abdeckmaterial mit dem Trägermaterial beispielsweise durch das Dämmmaterial hindurch vernäht werden.The cover material is glued, sewn, welded or clamped to the carrier material at least at the contact points. In addition, it can be provided that the covering material is also connected to the carrier material through the insulating material using suitable means. For example, the covering material can be sewn to the carrier material through the insulating material.

Das Dämmmaterial kann erfindungsgemäß zur Verbesserung der mechanischen Eigenschaften ein Bindemittel aufweisen. Geeignete Bindemittel sind z. B. Phenolharze oder anorganische Bindemittel, welche vorteilhafter Weise unbrennbar sind. Die ordnungsgemäß eingesetzten Dämmmaterialien können desweiteren Zusatzstoffe wie flammhemmende Mittel oder Mittel zur Staubbindung und/oder Hydrophobierung wie z. B. Mineralöle aufweisen.According to the invention, the insulation material can have a binder in order to improve the mechanical properties. Suitable binders are e.g. B. phenolic resins or inorganic binders, which are advantageously non-flammable. The properly used insulation materials can further additives such as flame retardants or agents for dust binding and / or hydrophobization such. B. have mineral oils.

In einer besonderen Ausgestaltung des erfindungsgemäßen Absorberelementes weist dieses einen Brennwert pro Masse des Absorbers ≤ 3,0 MJ/kg auf. Bei einer solchen Ausgestaltung erfüllt das Absorberelement die brandschutztechnischen Voraussetzungen der Klasse A gemäß der Norm DIN EN 13501-1 und kann in entsprechenden Bereichen eingesetzt werden. Erzielt wird ein Brennwert pro Masse des Absorberelementes ≤ 3,0 MJ/kg durch Verwendung entsprechender Träger- und/oder Abdeckmaterialien sowie geeigneter Dämmmaterialien gemäß den zuvor ausgeführten Maßgaben. Die Rohdichte des erfindungsgemäß eingesetzten Dämmmaterials kann zwischen 12 und 60 kg/m3 liegen.In a special embodiment of the absorber element according to the invention, it has a calorific value per mass of the absorber 3,0 3.0 MJ / kg. With such a configuration, the absorber element fulfills the fire protection requirements of class A according to the standard DIN EN 13501-1 and can be used in corresponding areas. A calorific value per mass of the absorber element ≤ 3.0 MJ / kg is achieved by using appropriate carrier and / or covering materials as well as suitable insulation materials in accordance with the previously stated requirements. The bulk density of the insulation material used according to the invention can be between 12 and 60 kg / m 3 .

Die erfindungsgemäßen Absorberelemente weisen eine Gesamtdicke von 10 bis 70 mm, bevorzugt zwischen 20 und 50 mm, und noch bevorzugter von ca. 20 mm auf.The absorber elements according to the invention have a total thickness of 10 to 70 mm, preferably between 20 and 50 mm, and more preferably of approximately 20 mm.

In einer Ausgestaltung des erfindungsgemäßen Absorberelementes wird die Rohdichte des substantiellen Bestandteils des Absorberelementes, also der Mineralwolle, bei unverändertem Bindemittel-Anteil angehoben. Hierdurch kann beispielsweise bei einem Träger- und Abdeckmaterial aus einer Polyethylenfolie mit einer Materialstärke von 20 µm bei Verwendung einer Steinwolle mit 3% Bindemittelanteil und mit einer Rohdichte von mindestens 44 kg/m3 ein Brennwert pro Masse des Absorberelementes von 2,99 MJ/kg erreicht werden.In one embodiment of the absorber element according to the invention, the bulk density of the substantial constituent of the absorber element, that is to say the mineral wool, is increased with the binder content unchanged. In this way, for example, in the case of a carrier and cover material made of a polyethylene film with a material thickness of 20 μm when using a rock wool with 3% binder content and with a bulk density of at least 44 kg / m 3, a calorific value per mass of the absorber element of 2.99 MJ / kg can be achieved.

Bei der Verwendung von Glaswolle mit 5% Bindemittelanteil und mit einer Rohdichte von mindestens 59 kg/m3 kann bei gleichem Träger- und/oder Abdeckmaterial ein Brennwert pro Masse Absorberelement von 2,92 MJ/kg erzielt werden.If glass wool with a 5% binder content and a bulk density of at least 59 kg / m 3 is used , a calorific value per mass of absorber element of 2.92 MJ / kg can be achieved with the same carrier and / or covering material.

Alternativ kann die Rohdichte der Mineralwolle deutlich geringer angehoben werden, wenn der Bindemittel-Anteil im Mineralwoll-Produkt reduziert wird. So kann beispielsweise bei einem verwendeten Träger- und Abdeckmaterial auf Basis von Polyethylenfolien mit einer Materialstärke von 20 µm bei Verwendung einer Steinwolle mit 2% Bindemittel und mit einer Rohdichte von mindestens 40 kg/m3 ein Brennwert pro Masse eines solchen Absorberelementes von 2,966 MJ/kg erreicht werden.Alternatively, the bulk density of the mineral wool can be increased significantly less if the proportion of binder in the mineral wool product is reduced. For example, when using a carrier and cover material based on polyethylene films with a material thickness of 20 µm, using a rock wool with 2% binder and with a gross density of at least 40 kg / m 3, a calorific value per mass of such an absorber element of 2.966 MJ / kg can be achieved.

Bei Verwendung von Glaswolle mit 4% Bindemittel und mit einer Rohdichte von mindestens 50 kg/m3 als Dämmmaterial beträgt der Brennwert pro Masse eines solchen Absorberelementes 2,97 MJ/kg.When using glass wool with 4% binder and with a bulk density of at least 50 kg / m 3 as insulation material, the calorific value per mass of such an absorber element is 2.97 MJ / kg.

Alternativ kann lose Wolle als Dämmmaterial eingesetzt werden. Hierbei handelt es sich um ein Produkt, das nahezu ohne Bindemittel und nur mit einem geringen Anteil von Hydrophobierungsölen ausgerüstet ist. Der Öl-Anteil beträgt im Regelfall 0,1% mit einem Brennwert von 42 MJ/kg Öl. Damit kann die Rohdichte der Mineralwolle (für Stein- und Glaswolle) von heute 27,5 kg/m3 bzw. 15 kg/m3 auf 34 kg/m3 geändert werden.Alternatively, loose wool can be used as insulation. This is a product that is equipped with almost no binder and only with a small proportion of hydrophobic oils. The oil content is usually 0.1% with a calorific value of 42 MJ / kg oil. This means that the bulk density of mineral wool (for rock and glass wool) can be changed from 27.5 kg / m 3 or 15 kg / m 3 to 34 kg / m 3 today.

Bei einer solchen Ausgestaltung und der Verwendung eines Träger- und Abdeckmaterials auf Basis von Polyethylenfolien mit einer Materialstärke von 20 µm kann ein Brennwert pro Masse von 2,944 MJ/kg erzielt werden.With such a configuration and the use of a carrier and cover material based on polyethylene films with a material thickness of 20 μm, a calorific value per mass of 2.944 MJ / kg can be achieved.

Das zuvor beschriebene Absorberelement hat bei einer Gesamtdicke von 20 mm nur eine geringe Festigkeit. Um die Festigkeit des Fasergefüges zu verbessern, kann erfindungsgemäß ein Vernadelungsprozess der losen Wolle vorgesehen sein.The previously described absorber element has only a low strength with a total thickness of 20 mm. In order to improve the strength of the fiber structure, a needling process of the loose wool can be provided according to the invention.

Als weitere Alternative können statt der zuvor beschriebenen "brennbaren" Bindemittel mit hohen Werten für die Verbrennungswärme/kg auch nichtbrennbare, anorganische Bindemittel-Systeme verwendet werden.As a further alternative, non-combustible, inorganic binder systems can also be used instead of the previously described “combustible” binders with high values for the heat of combustion / kg.

Hierbei werden erfindungsgemäß als brennbare Substanzen nur geringe Mengen von 0,1 bis 0,2% Mineralöle zur Staubbindung und Hydrophobierung eingesetzt. Bei 0,1% ergeben sich gleiche Rohdichten von 34 kg/m3 für Stein- und Glaswolle.Here, according to the invention, only small amounts of 0.1 to 0.2% of mineral oils are used as combustible substances for dust binding and hydrophobicization. At 0.1%, the same bulk densities of 34 kg / m 3 result for rock and glass wool.

Gemäß der Erfindung können auch zwei unterschiedliche Bindemittel, sowohl organischer als auch anorganischer Ausbildung, in unterschiedlichen Mengen in einem Absorberelement verwendet werden. In Abhängigkeit von der Menge des eingesetzten organischen Bindemittels ergeben sich für Steinwolle minimale Rohdichten von 34 bis 44 kg/m3 und für Glaswolle minimale Rohdichten von 34 bis 59 kg/m3.According to the invention, two different binders, both organic and inorganic, can also be used in different amounts in an absorber element. Depending on the amount of the organic binder used, there are minimal bulk densities of 34 to 44 kg / m 3 for rock wool and minimal bulk densities of 34 to 59 kg / m 3 for glass wool.

Alternativ können organische Bindemittel weiter modifiziert werden, so dass der Wert der Verbrennungswärme/kg fertig gemischtes Bindemittel entsprechend sinkt. In Abhängigkeit von dem Restwert der Verbrennungswärme des eingesetzten, modifizierten Bindemittels bestimmt sich dann die einzusetzende Rohdichte der Mineralwolle, um einen Brennwert pro Masse des Gesamtproduktes von ≤ 3,0 MJ/kg zu erreichen.Alternatively, organic binders can be modified further so that the value of the heat of combustion / kg of ready mixed binder drops accordingly. Depending on the residual combustion heat of the modified binder used, the raw density of the mineral wool to be used is then determined in order to achieve a calorific value per mass of the total product of ≤ 3.0 MJ / kg.

Hinsichtlich des Verfahrens wird die Aufgabe gelöst durch ein Verfahren zur Herstellung eines Absorberelementes, bei dem das faserförmige Dämmmaterial mit einem Flächengewicht von 0,1 bis 6 kg/m2 auf ein Trägermaterial aufgebracht wird und mit einem Abdeckmaterial abgedeckt wird. Das Abdeckmaterial und das Trägermaterial zusammen bilden ein Ummantelungsmaterial und werden mit der Maßgabe ausgewählt, dass das Ummantelungsmaterial ein Flächengewicht von 0,01 bis 0,17 kg/m2 bei einem Brennwert pro Masse von 0 bis 48 MJ/kg und einem Brennwert pro Fläche von 0 bis 4,0 MJ/m2 aufweist und bei dem das Absorberelement mit einem aus den Brennwerten des faserförmigen Dämmmaterials und des flächig ausgebildeten Ummantelungsmaterials gebildeten Gesamtbrennwert PCS ≤ 3,0 MJ/kg, insbesondere ≤ 2,0 MJ/kg ausgebildet wirdRegarding the method the object is achieved by a method for producing an absorber element, in which the fibrous insulation material having a basis weight of 0.1 to 6 kg / m 2 is applied to a substrate and is covered with a covering material. The covering material and the carrier material together form a sheathing material and are selected with the proviso that the sheathing material has a basis weight of 0.01 to 0.17 kg / m 2 with a calorific value per mass of 0 to 48 MJ / kg and a calorific value per area from 0 to 4.0 MJ / m 2 and in which the absorber element is formed with a total calorific value PCS 3,0 3.0 MJ / kg, in particular 2,0 2.0 MJ / kg, which is formed from the calorific values of the fibrous insulating material and the sheet-like cladding material

Hierbei können Trägermaterial und Abdeckmaterial vorteilhafterweise flächig ausgebildet sein. Das Trägermaterial und/oder das Abdeckmaterial können beispielsweise Kunststofffolie, ein Vlies, eine Metallfolie und/oder ein Gewebe sein. Die unterschiedlichen Eigenschaften des Trägermaterials und des Abdeckmaterials können darin begründet sein, dass unterschiedliche Materialien wie beispielsweise ein Vlies als Trägermaterial und eine Kunststofffolie als Abdeckmaterial verwendet werden oder, dass als Trägermaterial eine Kunststofffolie mit einer deutlich geringeren Wandstärke verwendet wird, welche gute schalltechnische Eigenschaften aufweist, während als Abdeckmaterial eine mechanisch stabile Kunststofffolie eingesetzt wird.In this case, the carrier material and the covering material can advantageously be made flat. The carrier material and / or the covering material can be, for example, plastic film, a nonwoven, a metal film and / or a fabric. The different properties of the carrier material and the cover material can be due to the fact that different materials such as a nonwoven as carrier material and a Plastic film are used as cover material or that a plastic film with a significantly smaller wall thickness is used as the carrier material, which has good acoustic properties, while a mechanically stable plastic film is used as the cover material.

Beim Einsatz von Kunststofffolien haben sich insbesondere Polyethylenfolien als geeignet erwiesen. Darüber hinaus sind auch Folien aus Polypropylen oder Polyethylen-Polypropylen Copolymeren erfindungsgemäß einsetzbar.When using plastic films, polyethylene films in particular have proven to be suitable. In addition, films made of polypropylene or polyethylene-polypropylene copolymers can also be used according to the invention.

Um die schalltechnischen Eigenschaften des Trägermaterials weiter zu verbessern kann vorgesehen sein, dieses schall- und gasdurchlässig auszubilden. Hierbei kann die Schall- und/oder Gasdurchlässigkeit materialimmanent sein, wie beispielsweise bei der Verwendung eines Vlieses, oder durch entsprechende Aufbereitung des Trägermaterials wie Perforierung oder Mikroperforierung von Folien erfolgen.In order to further improve the acoustic properties of the carrier material, it can be provided that it is sound and gas permeable. The sound and / or gas permeability can be inherent to the material, such as when using a fleece, or by appropriate preparation of the carrier material such as perforation or microperforation of foils.

Durch die gasdurchlässige Ausgestaltung des Trägermaterials kann dieses im erfindungsgemäßen Verfahren in vorteilhafter Weise an eine Fördereinrichtung angesaugt werden, wobei das auf das Trägermaterial aufgebrachte Dämmmaterial durch den angelegten Unterdruck auf dem Trägermaterial fixiert wird.Due to the gas-permeable design of the carrier material, it can advantageously be sucked onto a conveying device in the method according to the invention, the insulating material applied to the carrier material being fixed on the carrier material by the negative pressure applied.

Bei dem auf das Trägermaterial aufgebrachten Dämmmaterial handelt es sich vorteilhafterweise um Steinwollefasern und/oder Glaswollefasern.The insulation material applied to the carrier material is advantageously rock wool fibers and / or glass wool fibers.

Erfindungsgemäß ist vorgesehen, dass das Abdeckmaterial, nachdem das Dämmmaterial auf dem Trägermaterial aufgebracht wurde, mit dem Trägermaterial zur Ausbildung eines das Dämmmaterial enthaltenden Beutels verbunden wird. Hierbei werden das Trägermaterial und das Abdeckmaterial vorteilhaft wenigstens entlang der Berührungsflächen zwischen Abdeckmaterial und Trägermaterial verbunden. Darüber hinaus kann vorgesehen sein, das Abdeckmaterial mit dem Trägermaterial durch das Dämmmaterial hindurch mittels geeigneter Einrichtungen zu verbinden, wodurch die mechanischen Eigenschaften des entstehenden Absorberelementes beeinflusst werden können.According to the invention, it is provided that the covering material, after the insulating material has been applied to the carrier material, is connected to the carrier material to form a bag containing the insulating material. In this case, the carrier material and the covering material are advantageously connected at least along the contact surfaces between the covering material and the carrier material. In addition, it can be provided that the covering material with the carrier material through the insulating material to connect through suitable devices, whereby the mechanical properties of the resulting absorber element can be influenced.

Zur Verbindung des Abdeckmaterials mit dem Trägermaterial kann ein Vernähen, ein Verkleben, ein Verschweißen oder ein Aneinanderklammern vorgesehen sein.Sewing, gluing, welding or stapling can be provided to connect the covering material to the carrier material.

Bei der Verbindung der Trägerfolie aus einem Polymermaterial wie z. B. Polyethylen mit einer Abdeckfolie aus z. B. Aluminium oder Glasvlies wird das Polymermaterial der Trägerfolie durch Aufheizen in den Randbereichen bis zum Erweichungspunkt als "Klebstoff" verwendet, um keine zusätzliche Brandlast durch Klebstoff zu generieren.When connecting the carrier film made of a polymer material such. B. polyethylene with a cover made of z. B. aluminum or glass fleece, the polymer material of the carrier film is used by heating in the edge areas to the softening point as an "adhesive" in order not to generate any additional fire load from the adhesive.

Darüber hinaus kann es vorgesehen sein, dass Trägermaterial und/oder Abdeckmaterial zumindest teilweise mit dem Dämmmaterial verbunden sind.In addition, it can be provided that the carrier material and / or covering material are at least partially connected to the insulating material.

Bei der Verwendung von Kunststofffolien als Trägermaterial und/oder Abdeckmaterial kann beispielsweise das Verbinden mittels Schweißbalken erfolgen, mit welchem das Trägermaterial und das Abdeckmaterial aneinander geheftet werden.When using plastic foils as carrier material and / or cover material, for example, the connection can be made by means of welding bars with which the carrier material and the cover material are attached to one another.

Auf das Trägermaterial 2 wird ein Dämmmaterial 3 aufgebracht. Hierbei werden einzelne, der Größe des herzustellenden Absorberelementes angepasste Portionen des Dämmmaterials 3 voneinander beabstandet auf das Trägermaterial 2 aufgebracht. Das Dämmmaterial 3 wird sodann mit einem Abdeckmaterial 4 abgedeckt. Hierbei wird das Abdeckmaterial 4 so aufgebracht, dass es in die Zwischenräume 5 zwischen den Portionen des Dämmmaterials 3 einsinken kann oder mittels geeigneter Einrichtungen in die Zwischenräume 5 eingedrückt wird. Sodann werden Trägermaterial 2 und Abdeckmaterial 4 mittels einer Verbindungsvorrichtung 6 miteinander verbunden. Hierbei kann die Verbindungsvorrichtung 6 ein Schweißbalken, ein Nähkopf, eine Einrichtung zum Verkleben oder zum Zusammenklammern sein. In Förderrichtung ist eine Trennvorrichtung 7 vorgesehen, welche die entstandenen Absorberelemente voneinander trennt. An der Unterseite der Transporteinrichtung 1 kann eine Einrichtung zur Erzeugung eines Unterdrucks vorgesehen sein, mit welchem sich das Trägermaterial 2 und gegebenenfalls das Dämmmaterial 3 auf der Transporteinrichtung fixieren lassen. Fig. 1 shows a schematic representation of an apparatus for performing the method according to the invention. Here, a carrier material 2 is applied to a transport device 1. An insulating material 3 is applied to the carrier material 2. Individual portions of the insulating material 3 that are adapted to the size of the absorber element to be produced are applied to the carrier material 2 at a distance from one another. The insulating material 3 is then covered with a covering material 4. Here, the covering material 4 is applied in such a way that it can sink into the spaces 5 between the portions of the insulation material 3 or is pressed into the spaces 5 by means of suitable devices. Then carrier material 2 and cover material 4 are connected to one another by means of a connecting device 6 connected. Here, the connecting device 6 can be a welding bar, a sewing head, a device for gluing or for clamping together. A separating device 7 is provided in the conveying direction, which separates the absorber elements formed from one another. On the underside of the transport device 1, a device for generating a negative pressure can be provided, with which the carrier material 2 and possibly the insulating material 3 can be fixed on the transport device.

In Fig. 2 ist schematisch die Auftragung des Dämmmaterials 3 auf das Trägermaterial 2 gezeigt. Hierbei ist zu erkennen, dass es erfindungsgemäß vorgesehen sein kann, dass das Dämmmaterial 3 in in beiden Horizontalrichtungen voneinander beabstandeten Portionen aufgebracht werden kann, so dass die in Fig. 3 gezeigte Absorberelementanordnung auf dem Trägermaterial 2 entstehen kann.In Fig. 2 the application of the insulating material 3 to the carrier material 2 is shown schematically. It can be seen here that it can be provided according to the invention that the insulating material 3 can be applied in portions spaced apart in both horizontal directions, so that Fig. 3 shown absorber element arrangement can arise on the carrier material 2.

Fig. 4 zeigt einen Schnitt durch ein erfindungsgemäßes Absorberelement, mit einem Kern aus einem Dämmmaterial 3, einem Abdeckmaterial 4, einem Trägermaterial 2 und einer Verbindungsstelle 9 zwischen Trägermaterial und Abdeckmaterial 4. Fig. 4 shows a section through an absorber element according to the invention, with a core made of an insulating material 3, a covering material 4, a carrier material 2 and a connection point 9 between the carrier material and covering material 4.

Fig. 5 zeigt in einer dreidimensionalen graphischen Auftragung die Abhängigkeiten der Eigenschaften einer in einem erfindungsgemäßen Absorberelement einsetzbaren Folie hinsichtlich Flächengewicht, Brennwert und PCS-Wert. Hierbei stellt der schraffierte Bereich in der oberen rechten Ecke der Diagrammfläche einen Bereich dar, in welchem die Gesamteigenschaften der Folie in Abhängigkeit der Einzeleigenschaften Flächengewicht, Brennwert pro Fläche des Absorberelementes und Brennwert pro Masse des Absorberelementes außerhalb des erfindungsgemäßen Bereiches liegen. Die in der Graphik punktiert dargestellte Diagrammfläche stellt den Bereich der Gesamteigenschaft der Folie dar, in welchem eine entsprechende Gesamteigenschaften aufweisende Folie in einem erfindungsgemäßen Absorberelement einsetzbar ist. Fig. 5 shows in a three-dimensional graphical depiction the dependencies of the properties of a film that can be used in an absorber element according to the invention with regard to basis weight, calorific value and PCS value.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen erfindungsgemäßer Absorberelemente näher dargestellt, ohne dass sich die Erfindung jedoch auf diese Ausführungsbeispiele beschränken lässt.The invention is described in more detail below with reference to exemplary embodiments of absorber elements according to the invention, but without the invention being restricted to these exemplary embodiments.

Beispiel 1:Example 1:

Zur Herstellung eines erfindungsgemäßen Absorberelementes mit einer Abmessung von 1.200 X 600 X 30 mm (Länge X Breite X Höhe) wird eine auf Übermaß geschnittene Polyethylenfolie bereitgestellt. Das Übermaß beträgt dabei 40 mm pro Seite, so dass die Übermaßfolie eine Abmessung vom 1.280 mm X 680 mm aufweist. Die Folienstärke beträgt 20 µm, das spezifische Gewicht beträgt 940 kg/m3 und der Brennwert pro Masse 40 MJ/kg. Auf die bereitgestellte Folie wird maßhaltig, das heißt in einem Bereich von 1.200 X 600 X 30 mm Steinwolle mit einer Rohdichte von 38 kg/m3 und einem Bindemittelgehalt von 2 % aufgebracht. Der Brennwert pro Masse beträgt für das Bindemittel 25 MJ/kg. Somit ergibt sich für die eingesetzte Steinwolle ein Brennwert pro Masse von 0,5 MJ/kg. Bei einer Schichtdicke der Steinwolle von 30mm ergibt sich daraus ein Brennwert pro Fläche von 0,57 MJ/m2. Anschließend wird die aufgebrachte Steinwolle mit einer ebenfalls auf Übermaß geschnittenen Polyethylenfolie mit einer Materialstärke von 20 µm und der Brennwert pro Masse 40 MJ/kg und einem spezifischen Gewicht von 940 kg/m3 abgedeckt, wobei diese Folie im Unterschied zu der Unterfolie nicht perforiert ist. Die Ober- und Unterfolien werden mittels eines Schweißbalkens miteinander verschweißt, wodurch ein maßhaltiges geschlossenes Absorberelement mit unterschiedlichen physikalischen Eigenschaften auf den beiden großen Flächen entsteht. Zur Kennzeichnung der Ober- und Unterseite ist auf der Oberseite eine entsprechende Kennzeichnung mittels Farbaufdruck vorgesehen.To produce an absorber element according to the invention with a dimension of 1200 X 600 X 30 mm (length X width X height), a polyethylene film cut to oversize is provided. The oversize is 40 mm per side, so that the oversize film has a dimension of 1,280 mm X 680 mm. The film thickness is 20 µm, the specific weight is 940 kg / m 3 and the calorific value per mass 40 MJ / kg. Stone wool with a bulk density of 38 kg / m 3 and a binder content of 2% is applied in a dimensionally stable manner, that is to say in a range of 1,200 X 600 X 30 mm. The calorific value per mass for the binder is 25 MJ / kg. This results in a calorific value per mass of 0.5 MJ / kg for the rock wool used. With a layer thickness of stone wool of 30mm, this results in a calorific value per area of 0.57 MJ / m 2 . The stone wool applied is then covered with a polyethylene film, likewise cut to an oversize, with a material thickness of 20 μm and the calorific value per mass 40 MJ / kg and a specific weight of 940 kg / m 3 , this film, in contrast to the lower film, not being perforated . The top and bottom films are welded to each other by means of a welding bar, creating a dimensionally stable, closed absorber element with different physical properties on the two large surfaces. To mark the top and bottom, a corresponding marking by means of color printing is provided on the top.

Ein so hergestelltes Absorberelement weist einen Brennwert pro Fläche von 2,09 MJ/m2 und einen Brennwert pro Masse von 1,83 MJ/kg auf.An absorber element produced in this way has a calorific value per area of 2.09 MJ / m 2 and a calorific value per mass of 1.83 MJ / kg.

Beispiel 2:Example 2:

Zur Herstellung eines Absorberelementes mit der Abmessung 1.000 X 1.000 X 20 mm (Länge X Breite X Höhe) wird eine Polyethylenfolie mit einer Materialstärke von 20 µm und einem spezifischen Gewicht von 940 kg/m3 auf Übermaß zugeschnitten und als Unterfolie des Absorberelementes genutzt. Die Unterfolie weist einen Brennwert pro Masse von 45 MJ/kg auf. Auf die Unterfolie wird eine Steinwolle mit einer Rohdichte von 50 kg/m3 und einem Bindemittelgehalt von 0,7 % aufgebracht, bis eine Materialstärke von 20 mm erreicht ist. Die hierbei aufgebrachte Steinwolle weist ein Bindemittel mit einem Brennwert pro Masse von 25 MJ/kg auf. Unter Berücksichtigung der Rohrdichte ergibt sich daraus ein Brennwert pro Masse für die Steinwolle von 0,175 MJ/kg. Bei einer Schichtdicke der Steinwolle von 20 mm ergibt sich somit ein Brennwert pro Fläche von 0,175 MJ/m2. Auf die aufgebrachte Steinwolle wird eine ebenfalls aus einer Polyethylenfolie bestehende Oberfolie mit einer Stärke von 25 µm aufgebracht. Die als Oberfolie eingesetzte Polyethylenfolie weist einen Brennwert pro Masse von 40 MJ/kg und spezifisches Gewicht von 940 kg/m3 auf. Die Ober- und Unterfolien werden, wie in Beispiel 1, miteinander verschweißt, um ein entsprechendes Absorberelement herzustellen. Zur Kennzeichnung der Ober- und Unterseite ist wiederum eine Markierung mittels farbigem Aufdruck vorgesehen. Ein so hergestelltes Absorberelement weist einen Brennwert pro Fläche von 1,96 MJ/m2 und einen Brennwert pro Masse von 1,88 MJ/kg auf.To produce an absorber element with the dimensions 1,000 X 1,000 X 20 mm (length X width X height), a polyethylene film with a material thickness of 20 µm and a specific weight of 940 kg / m 3 is cut to size and used as the bottom film of the absorber element. The bottom film has a calorific value per mass of 45 MJ / kg. A rock wool with a bulk density of 50 kg / m 3 and a binder content of 0.7% is applied to the bottom film until a material thickness of 20 mm is reached. The stone wool applied here has a binder with a calorific value per mass of 25 MJ / kg. Taking into account the pipe density, this results in a calorific value per mass for the rock wool of 0.175 MJ / kg. With a rock wool layer thickness of 20 mm, this results in a calorific value per area of 0.175 MJ / m 2 . On top of the stone wool, a top film with a thickness of 25 µm, also made of a polyethylene film, is applied. The polyethylene film used as the top film has a calorific value per mass of 40 MJ / kg and specific weight of 940 kg / m 3 . The top and bottom films are, as in Example 1, welded together to produce a corresponding absorber element. Marking by means of colored printing is again provided to mark the top and bottom. An absorber element produced in this way has a calorific value per area of 1.96 MJ / m 2 and a calorific value per mass of 1.88 MJ / kg.
