Die vorliegende Erfindung betrifft ein neues Harzschaum-Vlies-Verbundprodukt, das dadurch gekennzeichnet ist, dass es aus Melaminharzschaum mit aufgenadeltem Kohlefaservlies besteht.The present invention relates to a novel resin foam-nonwoven composite product, which is characterized in that it consists of melamine resin foam with needled carbon fiber nonwoven.
Dabei besteht Kohlefaser vorzugsweise aus oxydiertem und/oder zyklisiertem Polyacrylnitril. Kohlefasern sind an sich schon seit langem bekannt und können durch Oxydation und/oder Teiloxydation von Viskose, Polyacrylnitril und Pech hergestellt werden. Die Einzelheiten über die Herstellung, Eigenschaften und bisherige Anwendung von Kohlenstoff-Fasern sind zusammengefasst in dem Aufsatz „Carbonfasern" des Instituts für Textiltechnik, Hochschule Aachen, veröffentlicht in der Zeitschrift Chemiefaser/Textilindustrie 39./91. Jahrgang 1989 (Dezember).Carbon fibers preferably consist of oxidized and/or cyclized polyacrylonitrile. Carbon fibers have been known for a long time and can be produced by oxidation and/or partial oxidation of viscose, polyacrylonitrile and pitch. The details of the production, properties and previous application of carbon fibers are summarized in the article "Carbon fibers" by the Institute for Textile Technology, Aachen University, published in the journal Chemiefaser/Textilindustrie 39th/91st year 1989 (December).
Zum nächstkommenden Stand der Technik wird auf die Deutsche Gebrauchsmusterschrift 297 22 595 mit der Bezeichnung „Harzschaum-Vlies-Verbundprodukt" hingewiesen, die als Anmelderin die Anmelderin vorliegender Erfindung aufweist.The closest prior art is German utility model 297 22 595 entitled “Resin foam-fleece composite product”, which has the applicant of the present invention as its applicant.
Der vorliegenden Erfindung liegt die überraschende Erkenntnis zu Grunde, dass ein Harzschaum-Vlies-Verbundprodukt aus Melamin-Harzschaum und Kohlefaservlies mit sprunghaft verbesserten thermischen Isolationseigenschaften dadurch geschaffen werden kann, dass das Kohlefaservlies auf den Harzschaum aufgenadelt ist.The present invention is based on the surprising discovery that a resin foam-nonwoven composite product made of melamine resin foam and carbon fiber fleece with dramatically improved thermal insulation properties can be created by needle-punching the carbon fiber fleece onto the resin foam.

Vorzugsweise liegt das erfindungsgemäße Verbundprodukt in Plattenform oder in Bahnenform vor, wobei die Bahnenform insbesondere als Rollenware gestaltet ist.Preferably, the composite product according to the invention is in plate form or in web form, wherein the web form is in particular designed as a roll product.
Zum Stand der Technik ist zu sagen, dass das Verbindung von Melaminharzschäumen mit Faservliesen bisher unter Verwendung eines drittren Mediums nämlich eines Klebers erfolgte, wodurch beispielsweise insbesondere die Schwerentflammbarkeit bzw. die angestrebte Unbrennbarkeit des Harzschaum-Vlies-Verbundprodukts nachteilige beeinflusst werden kann, obgleich nunmehr auch hochtemperaturfeste Kleber, die aber sehr teuer sind, zur Verfügung stehen. In der Regel bedingt ein Kleber einen sogenannten Energieanstieg, d.h. die Erhöhung der Entflammbarkeit.Regarding the state of the art, it should be noted that the connection of melamine resin foams with fiber fleeces has previously been carried out using a third medium, namely an adhesive, which can, for example, have a negative impact on the flame retardancy or the desired non-combustibility of the resin foam-fleece composite product, although high-temperature-resistant adhesives are now available, although these are very expensive. As a rule, an adhesive causes a so-called energy increase, i.e. an increase in flammability.
Ein weiterer Nachteil der Klebstoffverwendung besteht darin, dass im Brandfall der Kleber toxische Stoffe abgibt.Another disadvantage of using adhesives is that in the event of a fire, the adhesive releases toxic substances.
Der vorliegenden Erfindung liegt demgegenüber die Erkenntnis zu Grunde, dass durch die Tatsache, dass der Harzschaum mit dem Kohlefaservlies durch Vemadeln verbunden ist, die Schwerentflammbarkeit sowohl bezüglich des Schaums als auch des Vlieses nicht nachteilig beeinflusst wird.In contrast, the present invention is based on the finding that the fact that the resin foam is connected to the carbon fiber fleece by needling does not adversely affect the flame retardancy of either the foam or the fleece.
Ferner hat die Sprödigkeit des Melaminharzschaums den Fachmann offenbar bisher abgehalten, die Verbindung der beiden Komposit-Komponenten Vlies und Melaminharzschaum durch Vemadelung &zgr; u bewirken.Furthermore, the brittleness of the melamine resin foam has apparently prevented the expert from bonding the two composite components, fleece and melamine resin foam, by means of needle bonding.
Vorliegender Erfindung liegt ferner die Aufgabe zu Grunde, ein Harzschaum-Vlies-Kohlefaser-Verbundprodukt mit verbesserten Schallschluck-Eigenschaften herzustellen; in der Tat sind die Schallschluck-Eigenschaften des erfindungsgemäßen Produkts gegenüber den Produkten des nachtskommenden Standes der Technik sprunghaft verbessert. Das erfindungsgemäße Produkt besitzt nämlich im Gegensatz zu den Produkten, bei denen das Vlies mit dem Melamtnharzschaum durch eine Klebschicht verbunden ist, keine Schallwellensperre. The present invention is also based on the object of producing a resin foam-nonwoven-carbon fiber composite product with improved sound absorption properties; in fact, the sound absorption properties of the product according to the invention are dramatically improved compared to the products of the current state of the art. In contrast to the products in which the nonwoven is connected to the melamine resin foam by an adhesive layer, the product according to the invention does not have a sound wave barrier.
Der Fachmann hat ferner offenbar auch deshalb mit Kleber gearbeitet, weil die üblichen 2,5-Meter-Melaminharzschaumplatinen einer Nadelung nicht oder nur sehr schwierig zugänglich gemacht werden konnten.The expert also apparently worked with glue because the usual 2.5-meter melamine resin foam boards could not be made accessible to needling or could only be made very difficult.
Demgegenüber liegt vorliegender Erfindung ferner die Erkenntnis zu Grunde, dass eine Nadelung dann wirtschaftlich durchführbar ist, wenn der Melaminharzschaum auf wirtschaftliche Weise in langen Bahnen zur Verfügung steht, was beispielsweise durch Schälen der Schaumblöcke erreichbar ist.In contrast, the present invention is also based on the finding that needling can be carried out economically if the melamine resin foam is available in long strips in an economical manner, which can be achieved, for example, by peeling the foam blocks.
Nach einer weiteren Ausführungsform vorliegender Erfindung weist das Kohlenstoff-Faser-Vlies einen Gehalt an Polyester-Fasern und/oder Viskose-Fasern und/oder Polyamid-Fasern und/oder Phenolharzfasern auf.According to a further embodiment of the present invention, the carbon fiber fleece contains polyester fibers and/or viscose fibers and/or polyamide fibers and/or phenolic resin fibers.
