Description
Die vorliegende Erfindung betrifft ein Fußbodenbeschichtungs-Vlies für Messen und Ausstellungen, ein Herstellungsverfahren für eine Fußbodenbeschichtung und ein Verfahren zur Wiederaufbereitung einer Fußbodenbeschichtung. Eine Fußbodenbeschichtung für Messen und Ausstellungen hat eine geringe Dicke, etwa 4 mm, und muss dem Fußgängerverkehr während der Dauer der Messe oder Ausstellung standhalten.The The present invention relates to a floor coating nonwoven for measuring and exhibitions, a manufacturing process for a floor coating and a Process for the recycling of a floor coating. A floor coating for trade fairs and exhibits has a small thickness, about 4 mm, and must the pedestrian traffic while withstand the duration of the fair or exhibition.
Ein solches Fußbodenbeschichtungsvlies weist im Allgemeinen eine Verbundstruktur auf und ist aus zwei Schichten gebildet:
- – ein Netz von Fasern oder Filamenten, das im Allgemeinen "Nadelvlies-Matte" genannt wird, und die obere Schicht der Fußbodenbeschichtung bildet
- – Eine Matrix oder rückseitige Beschichtung, die in engem Kontakt mit der Rückseite der Nadelvlies-Matte steht, und die untere Schicht der Fußbodenbeschichtung bildet.
- - A network of fibers or filaments, which is generally called "needle felt mat", and forms the top layer of the floor coating
- A matrix or back coating that is in close contact with the back of the needled web and forms the bottom layer of the floor finish.
Derzeitig wird die Nadelflies-Matte auf der Basis von kurzen Fasern hergestellt, die mit einem Extrusions-Spinnverfahren erhalten werden. Die Fasern, deren Durchmesser und Länge der Anwendung des Produktes angepasst ist, sind aus neuen oder recycelten polymeren Thermoplasten wie Polyolefinen, Polyamiden oder Polyestern oder Mischungen dieser Polymere. Die rückseitige Beschichtung besteht im Wesentlichen aus Latex und synthetischen Harzen auf der Basis von Styrol und Butadien. Die Herstellung der Fußbodenbeschichtung besteht darin, die Rückseite der Nadelvlies-Matte gleichmäßig mit flüssigem Latex zu bestreichen und den Latex so polymerisieren zu lassen, dass eine ebene und gleichmäßige rückseitige Beschichtung entsteht. Der Nachteil einer solchen Fußbodenbeschichtung besteht darin, dass sie weder vollständig noch leicht recycelt werden kann, und deswegen nach Gebrauch, das heißt am Ende der Messe oder Ausstellung entsorgt werden muss. Latex ist nämlich nicht recyclierbar, so dass die rückseitige Beschichtung nicht recyclierbar ist. Außerdem ist es, um die thermoplastischen Polymere der Nadelvlies-Matte zu recyceln nötig, vorher die rückseitige Beschichtung von der Nadelvlies-Matte abzutrennen. Außerdem müssen, wenn die Nadelvlies-Matte aus thermoplastischen Polymeren besteht, die zu verschiedenen Familien gehören, wie zum Beispiel eine Nadelvlies-Matte, die aus einer Mischung von Polyolefinfasern und Polyesterfasern gebildet ist, beim recyceln die verschiedenen Polymere getrennt werden, weil sie durch ihre physikalischen Eigenschaften inkompatibel sind und keine homogene, in der Kunststoffindustrie verwendbare Mischung bilden können. Des Weiteren ist es im Allgemeinen nötig, dem Recycling-Material andere Bestandteile hinzuzufügen, um es verwenden zu können.current the needleflap mat is made on the basis of short fibers, obtained by an extrusion spinning process. The fibers, their diameter and length The application of the product is adapted from new or recycled polymeric thermoplastics such as polyolefins, polyamides or polyesters or mixtures of these polymers. The backside coating is made essentially based on latex and synthetic resins of styrene and butadiene. The production of the floor coating consists in it, the back the needle felt mat evenly with liquid Spreading latex and allowing the latex to polymerize that a flat and even back Coating is created. The disadvantage of such a floor coating is that they are neither completely nor easily recycled can, and therefore after use, that is at the end of the fair or exhibition must be disposed of. Latex is not recyclable, so that the back Coating is not recyclable. Besides, it's about the thermoplastic Need to recycle polymers of the needled nonwoven mat, before the back Separate coating from the needle-punch mat. In addition, if the needle-punch mat is made of thermoplastic polymers which belong to different families, such as a needle punch mat, made of a mixture of polyolefin fibers and polyester fibers is formed, while recycling the different polymers separated because they are incompatible by their physical properties are not homogeneous and usable in the plastics industry Mixture can form. Furthermore, it is generally necessary to recycle material to add other ingredients, to use it.
