Description

Verfahren zur Herstellung eines kunststoffbeschichteten Verbundmaterials.Process for the production of a plastic-coated composite material.

Zusatz zu Patent ........... (Patentanmeldung A 33 880 X/39 a) Es ist bekannt, Trägerbahnen wie Papier, Zellulose, Vliesse und Gewebe mit Kunststoff zu beschichten. Die herkömmlichen Anftragsverfahren sind das Arbeiten aus der Lösung, die Befilwung über Extruder mittels einer Breitschlitzdüse oder die Hitzekaschierung einer fertigen Folie auf dem Träger.Addendum to patent ........... (patent application A 33 880 X / 39 a) Es is known, carrier webs such as paper, cellulose, fleece and fabric with plastic to coat. The conventional application procedures are working from the solution, Filing via an extruder using a slot die or heat lamination a finished film on the carrier.

Ausserordentliche Schwierigkeiten bereitete es bisher hochschmelzende Kuhststoffilme, wie z.B. Polyamid, Polycarbonat, Polyester, Polyacetal u.s.w., deren Schmelzpunkt über 200°C liegt, mit der Trägerbahn zu guter Haftung zu bringen.So far it has caused extraordinary difficulties with high melting points Plastic films such as polyamide, polycarbonate, polyester, polyacetal, etc., their Melting point is above 200 ° C, to bring about good adhesion with the carrier web.

Es wurde nun gefunden, dass eine Befilmung von Trägern mit hochschmelzenden Kunststoffen wirtschaftlich und qualitativ in sehr hochwertiger Form durchgeführt werden kann, wen man die oben genannten Hochpolymere mit einem niederschmelzenden Kunststoff, z.B. Polyäthylen, im Blasverfahren in der Weise kombiniert, dass die einzelnen Kunststoffschichten aus zwei oder mehr konzentrisch zueinander gelegenen Düsen ausgepresst und unmittelbar nach dem Auspressen durch Aufblasen miteinander verbunden werden, wobei gemäß Ifauptpatent in dem Raum, den zwei einander benachbarte schlauchförmige Schichten vom Austritt aus den Ringdüsen bis zu ihrer Vereinigung miteinander einschliesen, ein mit einer der beiden Folienschläuchen reagierendes Gas eingebracht oder in diesem Raum ein polymerisationsfreudiges Gas durch Funkenentladung in einem Hochspannungsfeld zur Polymerisation gebracht wtrd, und dass hierauf der so gewonnene zweischichtige Film, mit der niederschmelzenen Schicht gegen die Trägerbahn gewendet, auf diese 9 mittels Wärme und Druck bzw.It has now been found that a film of carriers with high-melting Plastics carried out economically and qualitatively in a very high quality form can be if you can use the above high polymers with a low melting point Plastic, e.g. polyethylene, combined in the blow molding process in such a way that the individual plastic layers made up of two or more concentric layers Nozzles squeezed out and immediately after squeezing out by blowing them together be connected, according to If the main patent in the space, the two adjacent tubular layers from the exit from the ring nozzles to their union included with each other, one reacting with one of the two film tubes Introduced gas or in this space a polymerisation-friendly gas by spark discharge polymerized in a high voltage field, and that the Two-layer film obtained in this way, with the melted layer against the carrier web turned, on these 9 by means of heat and pressure or

Vakuum aufkaschiert wird. Hierdurch wird erreicht, dass sowohl die beiden Kunststoffschichten unter sich, wie die niederschmelzende Schicht mit der Trägerbahn eine zuverlässige Verbindung eingehen.Vacuum is laminated. This ensures that both the two layers of plastic under each other, like the low-melting layer with the Carrier web enter into a reliable connection.

BeSa aufbringen des Doppelfilmes kann mit Temperaturen zwischen dem Schmalzpunkt der Verbindungsschicht und dem Schmelzpunkt des hochschmelzenden Filmes gearbeitet werden, sodass zwar der Verbindungsfilm einwandfrei gufgeschmolzen wird, die Trägerbahn aber noch in ihrer Festigkeit erhalten bleibt und dadurch iicht verleitzt werden kann. Durch die Zweischichtigkeit können können auch die Filmeigenschaften kombiniert werden, zum Beispiel so, dass eine Kombination bestehend aus Polyäthylen und Polyamid einmal hoch wasserdampfdicht ist und gleichzeitig die guten Fett- Öl- und Aromadichtigkeiten und Kratzfestigkeiten des Polyamidfilmes aufweist.BeSa can apply the double film with temperatures between The melting point of the connecting layer and the melting point of the high-melting point film be worked so that the connection film is properly guf-melted, the carrier web, however, still retains its strength and is therefore not stranded can be. Due to the two-tier structure, you can can also do the Film properties are combined, for example so that there is a combination made of polyethylene and polyamide is once highly water vapor-tight and at the same time the good grease, oil and aroma impermeability and scratch resistance of the polyamide film having.

Die Pigur zeigt schematisch ein Verbundmaterial gemäß der Erfindung in starker Vergrösserung.Pigur shows schematically a composite material according to the invention in strong enlargement.

Auf der Trägerbahn 1 aus Papier, Gewebe oder einem Vliess befindet sich ein Zweischichtfilm, dessen äussere Schicht 2 ein hochschi'elzender Kunststoff wie Polyamid, Polycarbonat, Polyester, Polyacetal od. dgln. ist, und dessen innere, die Verbindung mit der trägerbahn 1 herstellende Schicht 3 aus einem niederschmelzenden Kunststoff, z.B. Polyäthylen besteht.Located on the carrier web 1 made of paper, fabric or a fleece a two-layer film, the outer layer 2 of which is a high-melting plastic such as polyamide, polycarbonate, polyester, polyacetal or the like. is, and its inner, the connection with the carrier web 1 producing layer 3 of a low-melting Plastic, e.g. polyethylene.
