Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Kunststoffverbundplatte nach der Gattung des Hauptanspruchs. Derartige Kunststoff­ verbundplatten sind in vielfältiger Weise bekannt. Sie sind bekannt beispielsweise als sogenannte beschichtete Spanplatten, wobei die Spanplatte aus Kunststoff und Holzspänen hergestellt wird, die unter Wärme gepreßt werden. Eine andere Kunststoffverbundplatte besteht darin, daß ein homogener Thermoplast zu einer Platte hergestellt, deren Oberfläche mit einer Dekorplatte versehen wird, die aus einem Duroplast besteht. Darüber hinaus sind auch andere Kunststoffverbundplatten bekannt. Grundsätzlich kann natürlich die Dekorplatte nur Folien­ dicke aufweisen.The invention is based on a plastic composite panel according to the genus of the main claim. Such plastic composite panels are known in many ways. they are known for example as so-called coated Chipboard, the chipboard made of plastic and Wood shavings are made that are pressed under heat will. Another plastic composite panel exists in that a homogeneous thermoplastic to a plate made whose surface with a decorative plate is provided, which consists of a thermoset. About that other plastic composite panels are also known. In principle, the decorative panel can of course only use foils have thickness.

Bei all diesen bekannten Kunststoffverbundplatten ist das Verbinden der Trägerplatte mit der Dekorplatte pro­ blemlos, da es sich um homogene Kunststoffe handelt, die problemlos über Kleber oder durch Aufwärmen bis zur Schmelztemperatur des Thermoplastes miteinander verbindbar sind.In all these known plastic composite panels  connecting the support plate with the decorative plate pro straightforward, since they are homogeneous plastics, the easily over glue or by warming up to the melting temperature of the thermoplastic with each other are connectable.

Zugrundeliegende AufgabeUnderlying task

Der Erfindung liegt die Aufgabe zugrunde, eine Kunststoff­ verbundplatte zu schaffen unter Verwendung von Sekundär­ materialien, also sogenannten Recyclingkunststoffen. Bekanntlich handelt es sich bei diesen Recyclingkunst­ stoffen um nichthomogene Mischungen, die vor allem auch Polyethylene enthalten und damit nach den Erfahrungen des Fachmannes nicht auf die Dauer haltbar mit Dekor­ platten beschichtbar sind, insbesondere auch deshalb, weil die bekannten Kleber jeweils nur bei der Verwendung von homogenen Kunststoffen selbst unterschiedlicher Art verwendbar sind. Vor allem wirkt sich hier aus, daß die Oberflächenbeschaffenheit der Recyclingkunststoffe je nach der nicht vorher bestimmbaren Mischung entspre­ chend unterschiedlich sind.The invention has for its object a plastic to create composite panel using secondary materials, so-called recycling plastics. As is well known, this is recycling art substances around non-homogeneous mixtures, above all Contain polyethylene and thus according to experience of the specialist not durable in the long run with decor plates are coatable, especially because because the known glue only in use of homogeneous plastics themselves different Are usable. Above all, that the surface quality of the recycled plastics depending on the mixture that cannot be determined beforehand are different.

Aus diesem Grunde werden Sekundärkunststoffe als Voll­ kunststoffmaterial bisher nur von in einem Stück ge­ spritzte Kunststoffmöbel für den Garten oder als Gehweg­ steine verwendet, mit dem Nachteil der durch die Recyc­ lingmasse vorbestimmten, meistens unansehnlichen Farb­ gebung. For this reason, secondary plastics are considered full plastic material so far only in one piece splashed plastic furniture for the garden or as a sidewalk stones used, with the disadvantage of being recycled ling mass predetermined, mostly unsightly color giving.  

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Kunststoffverbundplatte mit den kennzeichnenden Merkmalen des Anspruchs 1 und des An­ spruchs 5 hat gegenüber den gattungsgemäßen eingangs genannten Kunststoffverbundplatten den Vorteil, daß ein Produkt vorhanden ist, das nicht nur dem dringenden Umweltbedarf an zu verarbeitenden Sekundärkunststoffen Rechnung trägt, sondern vor allem den unterschiedlichsten mechanischen und chemischen Ansprüchen genügt, da aufgrund der dauerhaften Verbindung zwischen Trägerplatte und Dekorplatte die äußeren chemischen und mechanischen Eigenschaften durch die Dekorplatte bestimmt werden, hingegen die Stabilität der Platte durch die Trägerplatte. Die erfindungsgemäße Platte ist vor allem auch in Feucht­ räumen verwendbar, da kein Aufquillen der Trägerplatte als Kernmaterial stattfinden kann, wobei aufgrund der Dekorplatte Temperaturen ohne weiteres bis 80°C an der Oberfläche möglich sind, ohne daß die thermoplastische Trägerplatte angegriffen wird. Die Vielseitigkeit der erfindungsgemäßen Kunststoffverbundplatte ergibt sich vor allem durch die Möglichkeit der unterschiedlichsten Oberflächengestaltung der Dekorplatte. Dies gilt nicht nur für die Farbgebung, sondern auch für die Profilierung, beispielsweise als Schrumpffolie. Außerdem kann als Material der Dekorplatte solches gewählt werden, welches den verschiedensten Anwendungsgebieten genügt. The plastic composite panel according to the invention characterizing features of claim 1 and to Proverb 5 has compared to the generic entry mentioned plastic composite panels have the advantage that there is a product that is not just the urgent one Environmental requirements for secondary plastics to be processed Takes into account, but above all the most varied mechanical and chemical requirements are sufficient because of the permanent connection between the carrier plate and Decorative plate the outer chemical and mechanical Properties determined by the decorative panel on the other hand, the stability of the plate through the carrier plate. The plate according to the invention is above all moist can be used because there is no swelling of the carrier plate can take place as core material, due to the Decorative panel temperatures up to 80 ° C at the Surface are possible without the thermoplastic Carrier plate is attacked. The versatility of the Plastic composite panel according to the invention results especially through the possibility of the most varied Surface design of the decorative panel. This is not the case only for the coloring, but also for the profiling, for example as a shrink film. In addition, as Material of the decorative panel can be chosen which the most diverse areas of application is sufficient.  

Das in Anspruch 4 genannte Herstellungsverfahren hat vor allem den Vorteil, daß die bisher beim Fachmann vorhandene Voreingenommenheit überwunden wurde, Kunst­ stoffplatten, die auch Polyethylen enthalten, mit homo­ genen Dekorplatten zu verbinden. Entscheidend hierfür war das Oxidieren der zu verbindenden Oberfläche der Trägerplatte.Has the manufacturing method mentioned in claim 4 above all the advantage that the previously the specialist existing bias has been overcome, art sheets of fabric that also contain polyethylene with homo to connect the decor plates. Crucial for this was the oxidation of the surface to be joined Carrier plate.
