Abstract
Thermal and/or sound insulation is provided by an insulation member which contains dried paper pulp or paper slurry together with at least one vegetable product.The vegetable product is preferably derived from tree bark. Also claimed is a process for manufacture of an insulation member from paper torn up and formed into a pulp in liquid or paper sludge from paper manufacture, to which the vegetable product is added before the material is converted to the required form and dried. Preferably, the paper is waste paper, softened for e.g. 30 minutes in water.
Description
Die vorliegende Erfindung betrifft ein Isolationselement zur Wärme- und/oder Schalldämmung. Weiter bezieht sie sich auf ein Verfahren zur Herstellung dieses Isolationselementes.
Es sind viele Arten von Isolier- und Dämm-Material bekannt, beispielsweise zur Verwendung im Hochbau. Gewöhnlich wird es in Form von Isolations-Platten oder -Matten angeboten, wobei aus einer Mehrzahl von derartigen Isolationselementen die gewünschte Isolier- bzw. Dämm-Schicht herstellbar ist. Durch Schneiden oder Pressen können die Isolationselemente zu besonderen Verwendungszwecken auch in bestimmte Formen gebracht werden. Nachteilig ist, dass zur Herstellung dieser Isolationselemente jeweils an sich unerwünschte Zusätze, wie mindestens ein Bindemittel und meistens auch verschiedene Chemikalien erforderlich sind.
Die vorliegende Erfindung stellt sich daher die Aufgabe, ein Isolationselement zur Wärme- und/oder Schalldämmung sowie ein Verfahren zu dessen Herstellung zu schaffen, durch welche die genannten Nachteile vermieden werden können.
Das erfindungsgemässe Isolationselement entspricht den kennzeichnenden Merkmalen des Patentanspruchs 1. Das Herstellungs-Verfahren geht aus Patentanspruch 3 hervor.
Nachfolgend wird ein Ausführungsbeispiel des Erfindungsgegenstandes näher beschrieben.
Das wichtigste Grundmaterial des Isolationselementes ist Altpapier. Als weitere Materialien dienen vorzugsweise rein biologische Stoffe bzw. pflanzliche Produkte, wie Holzabfälle, insbesondere Holzrinde bzw. Holzschnitzel, sowie Stroh oder andere pflanzliche Abfall- oder Nebenprodukte.
Der Herstellungsvorgang des Isolationselementes läuft wie folgt ab: Das Altpapier wird zerhackt, während ca. 30 Minuten in Wasser eingelagert und anschliessend zu einem Brei verarbeitet, z.B. mit Hilfe eines Rührwerks. AIs Variante kann auch Papierschlamm, der bei der Papierherstellung in Papierfabriken anfällt, verwendet werden. Der Holzabfall wird, falls dies erforderlich ist, auf eine Körnung von höchstens 10 mm zerkleinert. Am besten erfolgt dies mittels einer Hammermühle. Die kleinen Holzschnitzel bzw. die Holzmehl-Körner werden danach getrocknet, vorzugsweise auf annähernd 25% Feuchtigkeit. Der zu Mehl oder Schnitzeln zerkleinerte und getrocknete Holzabfall wird nun dem Altpapier-Brei beigegeben und dieses Gemisch während ca. 5 Minuten gerührt. In einem weiteren Arbeitsgang wird das Altpapier/Holz-Gemisch in die gewünschte Form gegeben und gepresst.
Das austretende Wasser kann für die nächste Charge wiederverwendet werden und schafft da her keine Entsorgungsprobleme. Das in seine endgültige Form gepresste Isolationselement kann nun austrocknen, entweder durch natürliche Lufttrocknung oder in einer entsprechenden Trocknungseinrichtung. Das Isolationselement wird vorzugsweise in Plattenform ausgeliefert. Es ist jedoch auch jede beliebige andere Form denkbar.
Die Verbindung des Altpapier-Breis mit dem zerkleinerten, trockenen Holz, vorzugsweise Holzrinde, verbessert die Festigkeitseigenschaften und die Wärmedämmung des Isolationselementes und trägt wesentlich zur Qualität des Endproduktes bei. Je nach gewünschter Qualitätseigenschaft bzw. nach genauer Zweckbestimmung des Isolationselementes ist es aber auch möglich, Pflanzenabfälle wie Stroh, Traubentrester, zerkleinerte Maiskolben usw. beizugeben. Das Mischungsverhältnis Altpapier-Brei/ Holzabfall bzw. Pflanzenabfall kann ebenfalls entsprechend dem Verwendungszweck variiert werden. Diese Parameter haben einen wesentlichen Einfluss auf die Festigkeit, die statische Eigenstabilität und den Isolationswert des Isolationselementes.
Zur Herstellung dieses Isolationselementes werden keine weiteren Zusätze benötigt. Wesentlich ist, dass als Bindemittel dasjenige dient, welches von Haus aus bereits im Altpapier vorhanden ist.
Zu bestimmten Zwecken, wie zur Steigerung der Festigkeit oder zur Erzielung einer feuerfesten bzw. -hemmenden Isolierung, können indessen während der Herstellung dem Gemisch zusätzliche Bestandteile beigegeben werden. Zum ersten Zweck eignet sich insbesondere Zement. Für den zweiten empfiehlt sich die Beigabe eines entsprechenden Spezialsalzes.
Abgesehen von den genannten Spezialfällen, werden zur Herstellung des erfindungsgemässen Isolationselementes also nur Recyclingprodukte bzw. rein biologische Abfall- und/oder Nebenprodukte benötigt.
The present invention relates to an insulation element for thermal and / or acoustic insulation. It also relates to a method for producing this insulation element.
Many types of insulating and insulating material are known, for example for use in building construction. It is usually offered in the form of insulation panels or mats, the desired insulation or insulation layer being able to be produced from a plurality of such insulation elements. By cutting or pressing, the insulation elements can also be brought into certain shapes for special purposes. It is disadvantageous that in order to produce these insulation elements, undesirable additives such as at least one binder and usually also various chemicals are required.
The object of the present invention is therefore to create an insulation element for heat and / or sound insulation and a method for its production, by means of which the disadvantages mentioned can be avoided.
The insulation element according to the invention corresponds to the characterizing features of patent claim 1. The manufacturing method emerges from patent claim 3.
An exemplary embodiment of the subject matter of the invention is described in more detail below.
The most important basic material for the insulation element is waste paper. Purely biological substances or vegetable products, such as wood waste, in particular wood bark or wood chips, as well as straw or other vegetable waste or by-products are preferably used as further materials.
The production process for the insulation element is as follows: The waste paper is chopped up, stored in water for approx. 30 minutes and then processed into a paste, e.g. with the help of an agitator. As a variant, paper sludge which is produced in the paper production in paper factories can also be used. If necessary, the wood waste is crushed to a maximum grain size of 10 mm. This is best done using a hammer mill. The small wood chips or wood flour grains are then dried, preferably to approximately 25% moisture. The wood waste, which has been crushed into flour or chips, is then added to the waste paper pulp and this mixture is stirred for about 5 minutes. In a further step, the waste paper / wood mixture is put into the desired shape and pressed.
The escaping water can be reused for the next batch and therefore does not create any disposal problems. The insulation element pressed into its final shape can now dry out, either by natural air drying or in an appropriate drying device. The insulation element is preferably supplied in plate form. However, any other shape is also conceivable.
The connection of the waste paper pulp with the shredded, dry wood, preferably wood bark, improves the strength properties and the thermal insulation of the insulation element and contributes significantly to the quality of the end product. Depending on the desired quality or the exact purpose of the insulation element, it is also possible to add plant waste such as straw, grape pomace, crushed corn cobs, etc. The mixing ratio of waste paper / pulp / wood waste or plant waste can also be varied according to the intended use. These parameters have a significant influence on the strength, the static inherent stability and the insulation value of the insulation element.
No further additives are required to produce this insulation element. It is essential that the binding agent is that which is already present in the waste paper.
For certain purposes, such as to increase the strength or to achieve a fire-resistant or -resistant insulation, additional components can be added to the mixture during manufacture. Cement is particularly suitable for the first purpose. For the second, it is advisable to add an appropriate special salt.
Apart from the special cases mentioned, only recycling products or purely biological waste and / or by-products are required to produce the insulation element according to the invention.
