Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Bodenpaneels.The invention relates to a method for producing a floor panel.

Als Fußbodenbelag kommen vielfach Beläge in Form von Laminatpaneelen zur Anwendung. Weit verbreitet sind Laminatfußböden. Ein Laminat-Fußbodenpaneel besteht aus einer Trägerplatte aus Fasermaterial, in der Regel eine hoch- oder mittelverdichtete Faserplatte, auf deren Oberseite eine Dekorschicht, beispielsweise ein beharztes Dekorpapier, aufgebracht ist. Die Dekorschicht bestimmt die Optik des Laminats. Das so genannte Overlay bzw. die Versiegelung bildet eine spezialbeharzte Nutzschicht aus Lack, die dem Bodenpaneel eine hohe Oberflächenstrapazierfähigkeit verleiht. Auf der Unterseite der Trägerschicht kann ein Gegenzug aufgebracht sein. Dieser dient der Formstabilität und der Feuchtigkeitsabsperrung. Gegebenenfalls kann ferner auf der Unterseite eine Trittschallisolierung vorgesehen sein.As floor coverings are often coverings in the form of laminate panels for use. Widely used are laminate flooring. A laminate floor panel consists of a carrier plate of fiber material, usually a high- or medium-compressed fiberboard, on top of which a decorative layer, for example a resinated decor paper, is applied. The decorative layer determines the appearance of the laminate. The so-called overlay or the seal forms a special treated wear layer of paint, which gives the floor panel a high surface durability. On the underside of the carrier layer, a return can be applied. This serves the dimensional stability and the moisture barrier. Optionally, a footfall sound insulation can also be provided on the underside.

In der Regel besteht ein Laminatfußboden aus mehreren Reihen von in ihrer Konfiguration rechteckigen Bodenpaneelen. Auf einer Längsseite und einer Kopfseite besitzt das Bodenpaneel üblicherweise durchgehende Nuten und auf der jeweils gegenüberliegenden Längsseite bzw. Kopfseite durchgehende Federn, die an die Nuten formschlüssig angepasst sind. Durch die Verbindung von Nut und Feder werden die Fußbodenelemente verlegt, wobei das Bodenpaneel zweier benachbarter Reihen versetzt zueinander angeordnet ist.As a rule, a laminate floor consists of several rows of rectangular floor panels in their configuration. On one longitudinal side and one head side, the bottom panel usually has continuous grooves and, on the respectively opposite longitudinal side or head side, continuous springs which are adapted in a form-fitting manner to the grooves. By the connection of tongue and groove the floor elements are laid, the floor panel of two adjacent rows is arranged offset from one another.

Zur Verbindung des einzelnen Bodenpaneels ist dieses heute fast ausschließlich mit einem so genannten Klick-System versehen. Hierbei handelt es sich um mechanische Verriegelungsmittel an den Nuten und an den Federn, welche bei in einem Bodenbelag benachbarten Bodenpaneel miteinander in rastenden Eingriff gelangen. Hierdurch soll eine Fugenbildung im verlegten Fußbodenbelag durch Dehnungs- und Schrumpfungsvorgänge vermieden werden. Solche Bodenpaneelen sind beispielsweise durch die JP 3-169967 oder die DE 297 10 175 U1 bekannt. Ähnliche Lösungen gehen aus der DE 201 20 704 U1 oder der WO 98/58142 A1 sowie der WO 96/27721 A1 hervor.To connect the individual floor panel this is now almost exclusively provided with a so-called click system. These are mechanical locking means on the grooves and on the springs, which engage with each other in engaging in a floor covering floor panel in latching engagement. As a result, a joint formation in the laid floor covering by expansion and shrinkage operations should be avoided. Such floor panels are for example by the JP 3-169967 or the DE 297 10 175 U1 known. Similar solutions go out of the DE 201 20 704 U1 or the WO 98/58142 A1 as well as the WO 96/27721 A1 out.

Gängig ist, wie vorstehend bereits ausgeführt, ein Drei-Schicht-Aufbau des Bodenpaneels mit profilierten Fügeflächen, wobei die Trägerschicht aus einer verdichteten Faserplatte besteht. Die Faserplatten sind für den Zweck sehr gut geeignet. Sie weisen die notwendige Stabilität auf, sind gut zu bearbeiten und kostengünstig. Hochverdichtete und mittelverdichtete Faserplatten sind jedoch relativ starr und steif und passen sich dem Unterboden nicht an. Es ist kein thermoplastischer Fluss vorhanden. Dies ist häufig gut, mitunter aber auch nachteilig, insbesondere wenn aufgrund der Verlegesituation bzw. des Unterbaus eine gewisse Elastizität des Bodenbelags wünschenswert wäre.Is common, as already stated above, a three-layer structure of the floor panel with profiled joining surfaces, wherein the carrier layer consists of a compressed fiberboard. The fiberboard are very suitable for the purpose. They have the necessary stability, are easy to work with and cost-effective. High density and medium density fiberboards, however, are relatively rigid and stiff and do not conform to the subfloor. There is no thermoplastic flow. This is often good, but sometimes also disadvantageous, especially if a certain elasticity of the floor covering would be desirable due to the laying situation or the substructure.

Eine andere Form eines Bodenpaneels geht aus der EP 1 938 963 B1 hervor. Bei diesem Bodenpaneel besteht die Trägerschicht, dort als Kern bezeichnet, aus weichem PVC. Auf der Oberseite der Trägerschicht ist eine Dekorfolie vorgesehen, die mit einem Dekor bedruckt ist. Auf die Dekorfolie wird eine transparente Verschleißschicht aufgebracht, die ebenfalls aus PVC besteht.Another form of a floor panel goes out of the EP 1 938 963 B1 out. In this floor panel, the carrier layer, there referred to as the core, made of soft PVC. On top of the carrier layer, a decorative film is provided, which is printed with a decor. On the decorative film, a transparent wear layer is applied, which also consists of PVC.

Der Erfindung liegt, ausgehend vom Stand der Technik, die Aufgabe zugrunde, ein Verfahren zur Herstellung eines umweltfreundlichen und ohne PVC oder Einsatz von Weichmachern sowie Isocyanaten auskommendes Bodenpaneel aufzuzeigen.The invention is, starting from the prior art, the object of demonstrating a method for producing an environmentally friendly and without PVC or use of plasticizers and isocyanates deriving floor panel.

Die Lösung dieser Aufgabe besteht in einem Verfahren gemäß dem Merkmal von Anspruch 1.The solution to this problem consists in a method according to the feature of claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous developments of the invention are the subject of the dependent claims.

Die Trägerschicht des Bodenpaneels ist auf Basis eines mineralischen Werkstoffs und eines Bindemittels gebildet. Der mineralische Werkstoff wird in Pulver- oder Granulatform mit dem Bindemittel gemischt und zur Trägerschicht ausgebildet. Der mineralische Werkstoff ist frei von umwelt- oder gesundheitsbeeinträchtigenden Inhaltsstoffen. Gleiches gilt für das Bindemittel. Das Bodenpaneel weist eine hohe Umweltfreundlichkeit auf.The carrier layer of the floor panel is formed on the basis of a mineral material and a binder. The mineral material is mixed in powder or granular form with the binder and formed into a carrier layer. The mineral material is free of environmental or health impairing Ingredients. The same applies to the binder. The floor panel has a high environmental friendliness.

Erfindungsgemäß ist auf die Trägerschicht eine Vliesschicht aufgebracht. Die Dekorschicht ist dann vorzugsweise durch ein auf die Vliesschicht aufgedrucktes Dekor gebildet. Auch die Vliesschicht kann vor dem Bedrucken mit einer Grundierung versehen sein. Diese Ausführungsform ist besonders vorteilhaft, was die Stoßfestigkeit und die Elastizität des Bodenpaneels anbelangt. Das Vlies wirkt zudem wie eine Armierung und kann für besondere Eigenschaften modifiziert werden, beispielsweise in der antistatischen Wirkung. Als Vlies können auch Kevlar- oder Karbonfaser-Vliese eingesetzt werden.According to the invention, a nonwoven layer is applied to the carrier layer. The decorative layer is then preferably formed by a decor printed on the nonwoven layer decor. The nonwoven layer can also be provided with a primer before printing. This embodiment is particularly advantageous in terms of impact resistance and elasticity of the floor panel. The fleece also acts as a reinforcement and can be modified for special properties, for example in the antistatic effect. Kevlar or carbon fiber nonwovens can also be used as fleece.

Die Trägerschicht ist PVC- und weichmacherfrei, des Weiteren frei von Isocyanaten. Der mineralische Werkstoff gewährleistet eine hohe Eindruckbeständigkeit. Durch die Wahl des Bindemittels kann die Paneelsteifigkeit eingestellt werden. Die Trägerschicht kann mit modernen Fräs- und Profilierwerkzeugen bearbeitet und anwendungsspezifisch konfiguriert werden.The carrier layer is PVC- and plasticizer-free, furthermore free of isocyanates. The mineral material ensures a high impression resistance. By choosing the binder, the panel stiffness can be adjusted. The carrier layer can be processed with modern milling and profiling tools and configured for specific applications.

Ein nach dem erfindungsgemäßen Verfahren hergestelltes Bodenpaneel besteht aus der gegenüber Faserplatten oder Gipsplatten elastischeren, weniger spröden mineralischen Trägerschicht, welche oberseitig mit einem Dekor und einer Verschleißschicht versehen ist. Das Dekor bzw. die Dekorschicht ist vorzugsweise ein Vlies, insbesondere ein bedrucktes Vlies, die Verschleißschicht besteht vorzugsweise aus aminoplastischen Harzen. Das Bindemittel der Trägerschicht ist so formuliert, dass es der Trägerschicht und damit dem Bodenpaneel eine zweckoptimierte Elastizität verleiht. Darüber hinaus ist das Bodenpaneel wasserunempfindlich. Durch die Kombination der Werkstoffe und das Mischungsverhältnis der Trägerschicht sowie des synergistischen Zusammenspiels mit dem Aufbau der Dekorschicht und der Verschleißschicht ist das Bodenpaneel hinsichtlich Elastizität und Verformungseigenschaften sowie Wasseraufnahme/Quellung einstellbar. Besondere Bedeutung kommt hierbei der Art des Bindemittels und der Menge des Bindemittels zu.A floor panel produced by the method according to the invention consists of the less brittle mineral carrier layer which is more elastic than fibreboards or gypsum boards and which is provided on the upper side with a decoration and a wear layer. The decor or decorative layer is preferably a nonwoven, in particular a printed nonwoven, the wear layer is preferably made of aminoplastic resins. The binder of the carrier layer is formulated such that it gives the carrier layer and thus the bottom panel a purpose-optimized elasticity. In addition, the floor panel is insensitive to water. By combining the materials and the mixing ratio of the carrier layer and the synergistic interaction with the structure of the decorative layer and the wear layer, the floor panel is adjustable in terms of elasticity and deformation properties and water absorption / swelling. Particular importance is attached to the nature of the binder and the amount of binder.

Die Trägerschicht enthält mindestens 50 Vol.-% des mineralischen Werkstoffs. Insbesondere weist die Trägerschicht 70 Vol.-% bis 100 Vol.-%, vorzugsweise 75 Vol.-% bis 90 Vol.-% mineralischen Werkstoffanteils auf. Als mineralischer Werkstoff kommt vorzugsweise Gips, Kalkstein oder Dolomit bzw. ein Gemisch aus den vorgenannten Mineralien zur Anwendung.The carrier layer contains at least 50% by volume of the mineral material. In particular, the carrier layer comprises 70% by volume to 100% by volume, preferably 75% by volume to 90% by volume, of the mineral material portion. The mineral material used is preferably gypsum, limestone or dolomite or a mixture of the abovementioned minerals.

Der Bindemittelanteil in der Trägerschicht ist größer (>) 10 Vol.-%. Vorzugsweise liegt der Bindemittelanteil zwischen 18 Vol.-% und 28 Vol.-%, insbesondere zwischen 20 Vol.-% und 25 Vol.-%. Das Bindemittel bzw. der Bindemittelanteil wird abgestimmt auf die Korngröße und Kornverteilung der mineralischen Werkstoffe und insbesondere im Hinblick auf die gewünschten Eigenschaften, die das Bodenpaneel besitzen soll.The binder content in the carrier layer is greater (>) 10% by volume. The binder content is preferably between 18% by volume and 28% by volume, in particular between 20% by volume and 25% by volume. The binder or binder content is matched to the grain size and grain distribution of the mineral materials and in particular with regard to the desired properties, which should have the floor panel.

Im Rahmen der Erfindung ist das Bindemittel bei einer bevorzugten Ausführungsform ein wasserbasierter Acrylatharz. Hierbei handelt es sich um einen rein wasserbasierten und formaldehydfreien Acrylatharz, der umweltverträglich ist und sehr gute Bindeeigenschaften für die Herstellung erfindungsgemäßer Trägerschichten mit sich bringt.In the context of the invention, in a preferred embodiment, the binder is a water-based acrylate resin. This is a purely water-based and formaldehyde-free acrylate resin, which is environmentally friendly and brings very good binding properties for the production of carrier layers according to the invention.

Ein weiteres vorteilhaftes Bindemittel ist ein polymeres Bindemittel, insbesondere ein Bindemittel auf Basis von Vinylacetat und Ethylen-Copolymeren. Des Weiteren ist ein Biopolymer oder ein Polymer-Blend sehr gut als Bindemittel geeignet. Erfindungsgemäß kommen biologisch abbaubare polymere Bindemittel zum Einsatz. Hierbei bietet sich für die Praxis auch der Einsatz von Polymer-Blends an, bei denen es sich um ein Gemisch aus synthetischen und natürlichen Polymeren handelt. Hauptkomponente des Polymer-Blends ist ein natürliches Polymer aus einem nachwachsenden Rohstoff, beispielsweise Stärke, in einem Anteil von mindestens 65 %.Another advantageous binder is a polymeric binder, in particular a binder based on vinyl acetate and ethylene copolymers. Furthermore, a biopolymer or a polymer blend is very suitable as a binder. According to the invention, biodegradable polymeric binders are used. This also lends itself in practice to the use of polymer blends, which are a mixture of synthetic and natural polymers. Main component of the polymer blend is a natural polymer of a renewable raw material, such as starch, in a proportion of at least 65%.

Die Trägerschicht besitzt eine flächenbezogene Masse von größer oder gleich (≥) 3,0 kg/m2. Diese relativ hohe Massenbelegung (oft auch als Flächengewicht bezeichnet) sorgt für ein gutes Liegeverhalten des Bodenpaneels. Durch die Wahl und die Zusammensetzung des Bindemittels erhält die Trägerschicht und damit das gesamte Bodenpaneel ein plastoelastisches Liegeverhalten, was Spannungen aus dem Overlay bzw. der Versiegelung entgegenwirkt und Verzugserscheinungen minimiert oder sogar eliminiert.The carrier layer has a basis weight of greater than or equal to (≥) 3.0 kg / m 2 . This relatively high mass occupancy (often referred to as basis weight) ensures a good lying behavior of the floor panel. Due to the choice and the composition of the binder, the carrier layer and thus the entire floor panel receives a plastoelastic lying behavior, causing tensions counteracts the overlay or sealing and minimizes or even eliminates distortion.

Die Herstellung Komponenten für die Trägerschicht kann durch Extrusion erfolgen. Hierbei werden der mineralische Werkstoff und das Bindemittel in einem Extruder zu Pellets oder Granulat geformt und anschließend diese körnigen Stoffe zur Trägerschicht verarbeitet. Dies erfolgt vorzugsweise auf einer kontinuierlichen Bandpresse, einer so genannten Thermomeltanlage. Prinzipiell ist dies aber auch auf einer CPL (Continuous Pressure Laminate) -Anlage oder ähnlichem möglich. Die extrudertechnische Herstellung der Trägerschicht wird insbesondere eingesetzt bei polymeren Bindemitteln, insbesondere bei einem Bindemittel in Form von Vinylacetaten.The preparation of components for the carrier layer can be effected by extrusion. Here, the mineral material and the binder are formed in an extruder into pellets or granules and then processed these granular materials to the carrier layer. This is preferably done on a continuous belt press, a so-called Thermomeltanlage. In principle, however, this is also possible on a CPL (Continuous Pressure Laminate) system or the like. The extrudate production of the carrier layer is used in particular in polymeric binders, in particular in a binder in the form of vinyl acetates.

Alternativ ist es möglich, die Pellets/Granularien auf eine Unterlage auszustreuen und anschließend in einer zyklisch arbeitenden Kurztaktpresse zu einer Trägerschicht zu verpressen bzw. zu verschmelzen.Alternatively, it is possible to spread the pellets / granules on a substrate and then to press in a cyclically operating short-cycle press to a carrier layer or to merge.

Bei Acrylatbindemitteln werden diese dem mineralischen Werkstoff zugemischt und dieses Gemisch dann zur Trägerschicht geformt, beispielsweise indem das pastöse, streichfähige Gemisch auf eine Bandanlage aufgebracht, konfiguriert und getrocknet wird.In the case of acrylate binders, these are admixed with the mineral material and this mixture is then shaped into a carrier layer, for example by applying the pasty, spreadable mixture to a belt system, configuring it and drying it.

Grundsätzlich kann die Trägerschicht Zuschlagsstoffe, insbesondere biologische Zuschlagsstoffe, in einem Anteil von kleiner als (<) 50 Vol.-% enthalten. Hierbei ist insbesondere an den Einsatz von Zuschlagsstoffen in Form von Kork oder Ledergranulat und ähnlichen biologischen Zuschlagstoffen gedacht. Auch Gummi oder Naturkautschuk sind als Zuschlagstoff geeignet.In principle, the carrier layer can contain additives, in particular biological additives, in a proportion of less than (<) 50% by volume. This is particularly intended to the use of aggregates in the form of cork or leather granules and similar biological additives. Also rubber or natural rubber are suitable as an additive.

Das spezifische Gewicht der Trägerschicht liegt zwischen 1,5 kg/m3 und 2,5 kg/m3, insbesondere bei ca. 2,0 kg/m3.The specific weight of the carrier layer is between 1.5 kg / m 3 and 2.5 kg / m 3 , in particular about 2.0 kg / m 3 .

Die praktische Anwendung des erfindungsgemäßen Bodenpaneels wird dadurch verbessert, dass die Seitenränder des Bodenpaneels profiliert und mit Verriegelungsmitteln nach Art eines Klick-Systems versehen sind. Überraschender Weise hat sich gezeigt, dass die Trägerschicht aus mineralischem Werkstoff eine sehr gute Profilierbarkeit hat. Die Trägerschicht kann mit modernen Fräs- und Profilierwerkzeugen sehr gut bearbeitet und an ihren Seitenrändern mit einer entsprechenden Profilierung einschließlich Verriegelungsmitteln versehen werden.The practical application of the floor panel according to the invention is improved in that the side edges of the floor panel are profiled and provided with locking means in the manner of a click system. Surprisingly, it has been shown that the carrier layer of mineral material a has very good profiling. The carrier layer can be processed very well with modern milling and Profilierwerkzeugen and provided at their side edges with a corresponding profiling including locking means.

Grundsätzlich kann die Dekorschicht aus einem bedruckten Dekorpapier bestehen. Eine Dekorschicht aus Dekorpapier ist relativ kostengünstig.In principle, the decorative layer may consist of a printed decorative paper. A decorative layer of decorative paper is relatively inexpensive.

Als Verschleißschutz und Versiegelung ist das Bodenpaneel oberseitig mit einem Overlay versehen. Das Overlay ist ein- oder mehrschichtig ausgebildet und besteht aus transparenten Lacken und/oder transparenten Harzen mit gegebenenfalls verschleißerhöhenden Zuschlagsstoffen wie Korund. Auch die Einarbeitung von Effektpartikeln in das Overlay ist möglich.As wear protection and sealing, the floor panel is provided with an overlay on the upper side. The overlay is formed on one or more layers and consists of transparent paints and / or transparent resins with optionally wear-increasing additives such as corundum. The incorporation of effect particles into the overlay is also possible.

Zu einer Erhöhung der Stabilität und zur Vermeidung von Dimensionsveränderungen kann das Bodenpaneel unterhalb oder oberhalb der Trägerschicht mit einem Stabilisierungsgewebe versehen sein.To increase the stability and to avoid dimensional changes, the floor panel below or above the carrier layer can be provided with a stabilizing fabric.

Zur Herstellung eines Bodenpaneels wird ein Mehrschichtkörper hergestellt. Der Mehrschichtkörper umfasst eine Trägerschicht auf Basis eines mineralischen Werkstoffs sowie zumindest eine Dekorschicht und ein Overlay. Zwischen der Trägerschicht und der Dekorschicht kann eine Vliesschicht angeordnet werden. Auch kann die Dekorschicht durch eine mit einem Dekor bedruckte Vliesschicht gebildet sein. Anschließend wird der Mehrschichtkörper einer Presse zugeführt und in der Presse die Schichten des Mehrschichtkörpers unter Druck und Temperatur miteinander verpresst.To produce a floor panel, a multi-layer body is produced. The multilayer body comprises a carrier layer based on a mineral material and at least one decorative layer and an overlay. A nonwoven layer can be arranged between the carrier layer and the decorative layer. The decorative layer can also be formed by a nonwoven layer printed with a décor. Subsequently, the multilayer body is fed to a press and the layers of the multilayer body are pressed together under pressure and temperature in the press.

Der Pressvorgang wird bei einer Temperatur zwischen 120 °C und 200 °C durchgeführt. Der Druck beim Pressvorgang beträgt zwischen 1.500 kPa und 6.000 kPa.The pressing process is carried out at a temperature between 120 ° C and 200 ° C. The pressure during the pressing process is between 1,500 kPa and 6,000 kPa.

Die Trägerschicht aus mineralischem Werkstoff, der durch ein biologisches Bindemittel gebunden ist, wird beim Pressvorgang zumindest teilweise bzw. bereichsweise elastifiziert. Dies erhöht die Verbindung mit den übrigen Schichten des Bodenpaneels. Vorteilhaft ist dies insbesondere, um dem Bodenpaneel trotz eines dünnen Overlays Strukturen zu verleihen. Hierbei können tiefere Strukturen als bisher üblich erzeugt werden. Bei der Verpressung werden die Oberflächenstrukturen nach Art einer Maserung und Glanzgrade in das Bodenpaneel bzw. deren Oberfläche gepresst. Hierzu wird das Overlay bzw. das Harz, welches beim Pressvorgang das Overlay bildet, flexibel eingestellt, so dass das Harz bei der Verpressung fließfähiger ist, sich filmartig verteilt und anschließend aushärtet.The carrier layer of mineral material, which is bound by a biological binder, is at least partially or partially elasticized during the pressing process. This increases the connection with the remaining layers of the floor panel. This is particularly advantageous in order to give structures to the floor panel despite a thin overlay. Here, deeper structures than previously customary. During pressing, the surface structures are pressed into the floor panel or its surface in the manner of a grain and gloss levels. For this purpose, the overlay or the resin, which forms the overlay during the pressing process, set flexible, so that the resin during the compression is flowable, distributed like a film and then cured.

Die Dekorschicht und/oder die Vliesschicht können auch auf die Trägerschicht gebracht werden, wenn die Trägerschicht noch nicht vollständig ausgehärtet ist. Die Herstellung der Trägerschicht ist bei dieser Vorgehensweise in den Prozess der Fertigung des Bodenpaneels eingebunden. Die mineralischen Werkstoffe und das Bindemittel werden gemischt und vorzugsweise zu großformatigen Platten, beispielsweise in den Abmessungen von 2,10 m x 2,60 m in einer Stärke von 4 mm bis 12 mm, vorzugsweise 5 mm bis 6 mm, geformt. Noch bevor die Trägerschicht abgebunden bzw. vollständig ausgehärtet ist, werden die weiteren Schichten, also zumindest die Dekorschicht, gegebenenfalls die Vliesschicht und das Overlay auf die Trägerschicht aufgebracht und dieser Mehrschichtaufbau dann verpresst.The decorative layer and / or the nonwoven layer can also be applied to the carrier layer if the carrier layer has not yet completely cured. The production of the carrier layer is involved in this process in the process of manufacturing the floor panel. The mineral materials and the binder are mixed and preferably into large-sized plates, for example in the dimensions of 2.10 m x 2.60 m in a thickness of 4 mm to 12 mm, preferably 5 mm to 6 mm formed. Even before the carrier layer is set or completely cured, the further layers, ie at least the decorative layer, if appropriate the nonwoven layer and the overlay, are applied to the carrier layer and this multilayer structure is then pressed.

Die Trägerschicht aus durch das Bindemittel gebundenem mineralischem Werkstoff kann auch vollständig ausgehärtet zur Herstellung einer erfindungsgemäßen Bodenpaneels eingesetzt werden. Die weiteren Schichten werden dann gegebenenfalls unter Zusatz von Fixiermitteln und/oder Klebstoffen im Schichtaufbau aufgetragen.The carrier layer of mineral material bound by the binder can also be used completely cured for producing a floor panel according to the invention. The further layers are then optionally applied with the addition of fixatives and / or adhesives in the layer structure.

Bei dem Vliesstoff handelt es sich um ein textiles Flächengebilde aus einzelnen Fasern oder Filamenten. Die Vliesschicht kann beispielsweise aus einem Glasvlies oder Polyester gebildet sein. Grundsätzlich ist auch eine Kombination von Glas und Polyester möglich. Die Vliesschicht kann ferner aus Polyamid oder Polyethylenterephthalat (Kurzzeichen PET) hergestellt sein. Darüber hinaus ist auch eine Kombination aus Polyamid und Polyethylenterephthalat denkbar. Das Vlies kann auch Fasern unterschiedlicher Festigkeit enthalten, insbesondere können Versteifungsfasern aus Kevlar oder Karbon in das Vlies eingearbeitet sein. Die Vliesschicht zeichnet sich durch eine hohe Festigkeit und Stabilität aus. Zudem ist die Vliesschicht besonders gut zur Aufnahme des Dekors geeignet. Besonders vorteilhaft besteht die Vliesschicht aus endlos gesponnenen Filamenten, die lösungs- und bindemittelfrei zur Vliesschicht verarbeitet werden.The nonwoven fabric is a textile fabric of individual fibers or filaments. The nonwoven layer can be formed, for example, from a glass fleece or polyester. Basically, a combination of glass and polyester is possible. The nonwoven layer may further be made of polyamide or polyethylene terephthalate (abbreviation PET). In addition, a combination of polyamide and polyethylene terephthalate is conceivable. The nonwoven may also contain fibers of different strength, in particular stiffening fibers of Kevlar or carbon may be incorporated into the nonwoven. The nonwoven layer is characterized by a high strength and stability. In addition, the nonwoven layer is particularly well suited for receiving the decor. Especially Advantageously, the nonwoven layer consists of endless spun filaments, which are solvent and binder-free processed to nonwoven layer.

Der Mehrschichtkörper 35 wird dann einer Presse zugeführt und mittels Hitze und Druck gehärtet. Hierbei wird der Pressenvorgang bei einer Temperatur zwischen 120 °C und 200 °C sowie einem Druck zwischen 1.500 kPa und 6.000 kPa durchgeführt.The multilayer body 35 is then fed to a press and cured by means of heat and pressure. Here, the pressing operation is carried out at a temperature between 120 ° C and 200 ° C and a pressure between 1,500 kPa and 6,000 kPa.

Beim Pressvorgang wird die Trägerschicht 6 zumindest teilweise elastifiziert, insbesondere erfolgt eine Elastifizierung in einer oberseitigen Schicht. Beim Pressvorgang kommt es zu einer innigen Verbindung der Schichten des Mehrschichtkörpers 35, wobei beim Pressvorgang in das Bodenpaneel 1 - 5 sichtseitige Oberflächenstrukturen und/oder Glanzgrade gepresst werden.During the pressing process, the carrier layer 6 is at least partially elasticized, in particular an elastification takes place in an upper-side layer. During the pressing process, there is an intimate connection of the layers of the multi-layer body 35, wherein in the pressing process in the bottom panel 1 - 5 surface-side structures and / or degrees of gloss are pressed.

Zur Herstellung der Trägerschicht 6 werden mineralische Werkstoffe mit Bindemittel der erfindungsgemäß vorgesehenen Art gemischt und zur Trägerschicht 6 ausgebildet. Hierbei kann eine großformatige Platte in einer Abmessung von 2,10 m x 2,60 m in einer Stärke von 4 mm bis 12 mm, vorzugsweise 5 mm bis 6 mm, geformt werden. Möglich ist, dass die Dekorschicht 7 und/oder die Vliesschicht 32 auf die Trägerschicht 6 aufgebracht werden, bevor die Trägerschicht 6 vollständig ausgehärtet ist.To produce the carrier layer 6, mineral materials are mixed with binders of the type provided according to the invention and formed into the carrier layer 6. Here, a large-sized plate in a dimension of 2.10 m x 2.60 m in a thickness of 4 mm to 12 mm, preferably 5 mm to 6 mm, are formed. It is possible that the decorative layer 7 and / or the nonwoven layer 32 are applied to the carrier layer 6 before the carrier layer 6 is completely cured.

Nach dem Pressvorgang liegt die großformatige Platte bestehend aus Trägerschicht 6, Dekorschicht 7, gegebenenfalls der Vliesschicht 32 und dem Overlay 8 vor. Diese großformatige Platte wird dann in einzelne Bodenpaneele 1 - 5 geteilt und an den längsseitigen und kopfseitigen Seitenrändern profiliert und mit Verriegelungsmitteln 11 versehen.After the pressing process, the large-format plate consisting of support layer 6, decorative layer 7, optionally the nonwoven layer 32 and the overlay 8 is present. This large-format plate is then divided into individual floor panels 1 - 5 and to the profiled longitudinal side and head side edges and provided with locking means 11.

Das Bodenpaneel 1 - 5 besitzt eine Stärke von 4 mm bis 12 mm, vorzugsweise 5 mm bis 6 mm. Das einzelne Bodenpaneel 1 - 5 ist selbstliegend und benötigt keine Verklebung zum Untergrund.The floor panel 1 - 5 has a thickness of 4 mm to 12 mm, preferably 5 mm to 6 mm.
