Abstract

Decorative panels are produced by covering them with flocculated foils which are made of shrinkable plastics. On shrinking the foils enclose the panels totally without formation of any folds. Foils are coated with an adhesive which can be activated by irradiation, the adhesive is coated with floccules and the adhesive activated. Activation may be effected using electron beam irradiation induced by using a voltage varying from 150-600 kV.

Description

Beflockte Folien Flocked foils

Es ist bekannt beflockte Folien und Platten herzustellen, in dem man die Folien oder Platten mit Klebstoff beschichtet und anschließend den Flock aufbringt. Die hierfür geeigneten Klebstoffe können lufttrocknend, hitzehärtbar oder strahlenvernetzbar sein. Dem Fachmann sind die fUr diese Zwecke geeigneten Klebstoffe, die Folien oder Platten sowie die Auftragetechniken hinsichtlich des Klebstoffs und des Flocks ebenfalls bekannt, so daß an dieser Stelle darauf nicht näher eingegangen zu werden braucht.It is known to produce flocked foils and plates by using the foils or plates are coated with adhesive and then the flock is applied. The adhesives suitable for this can be air-drying, heat-curing or radiation-crosslinkable be. The person skilled in the art is the adhesives suitable for these purposes, the films or Plates as well as the application techniques with regard to the glue and the flock as well known, so that it does not need to be discussed in more detail at this point.

Üblicherweise verwendet man bei der Herstellung der beflockten Folien hitzehärtbare Klebstoffe, die nach der Beflockung normalerweise in einem industriellen Herstellungsprozeß durch Wärmeeinwirkung in einem Trockenofen gehärtet werden und auf diese Weise das Trägermaterial fest mit dem Flock verbinden.Usually one uses in the production of the flocked foils thermosetting adhesives that are normally used in an industrial after flocking Manufacturing process by the action of heat in a drying oven hardened and in this way connect the carrier material firmly to the flock.

Die beflockten Folien und Platten finden insbesondere fiir Dekorationszwecke Anwendung. Häufig ist es dabei erforderlich die beflockte Folie um eine starre, gegebenenfalls unebene Unterlage faltenfrei zu spannen. Um dies möglichst gut und rationell durchführen zu können bedient man sich häufig elastischer, beflockter Folien.The flocked foils and plates are used in particular for decorative purposes Use. It is often necessary to wrap the flocked film around a rigid, if necessary, stretch the uneven surface so that it is free from creases. To do this as well as possible and To be able to perform efficiently, one often uses more elastic, flocked ones Foils.

Trotz des Einsatzes solcher Folien ist die damit verbundene Verfahrenstechnik noch ziemlich aufwendig und führt nicht immer zu faltenfreien Umhullungen. Aufgabe der Erfindung war es daher, eine beflockte Folie zu schaffen, die sich nach Aufbringung auf die zu Uberspannende Unterlage mühelos faltenfrei spannen läßt.Despite the use of such films, the associated process technology is still quite complex and does not always lead to wrinkle-free wrappings. task of the invention was therefore to create a flocked film which, after application can be stretched effortlessly without creases on the surface to be spanned.

Gelöst wird diese Aufgabe dadurch, daß man eine beflockte Schrumpffolie herstellt, in dem man eine Schrumpffolie mit einem strahlenvernetzbaren Klebstoff beachichtet, dann den Flock in an sich bekannter Weise aufbringt und den Klebstoff mit einer für den Jeweiligen Klebstoff geeigneten Strahlenquelle vernetzt. Insbesondere wird gemäß der Erfindung ein Klebstoff eingesetzt, der mittels eines Elektronenstrahlers, insbesondere eines solchen, der mit einer Hochspannung von 150 bis 600 kV arbeitet, kalt gehärtet werden kann.This problem is solved by using a flocked shrink film by a shrink film with a radiation-crosslinkable adhesive noted, then applies the flock in a known manner and the adhesive cross-linked with a radiation source suitable for the respective adhesive. In particular an adhesive is used according to the invention, which by means of an electron gun, especially one that works with a high voltage of 150 to 600 kV, can be cold hardened.

Die gemäß der Erfindung eingesetzten Schrumpffolien, die 3e nach der Streckung, die sie bei ihrer Herstellung erfahren haben, bei Erwärmung in nur einer Richtung, in einer Richtung besonders stark oder in allen Richtungen gleichmäßig schrumpfen, sind ebenfalls bekannt, wurden aber bisher als Grundlage für die Herstellung von beflockten Folien nicht eingesetzt.The shrink films used according to the invention, the 3e after Stretching that they experienced in their manufacture, when heated in just one Direction, particularly strong in one direction or uniform in all directions shrink, are also known, but have so far been used as the basis for manufacture not used by flocked foils.

Bei Verwendung der erfindungsgemäß hergestellten beflockten Schrumpffolie Uberzieht man die zu bespannenden Gegenstände mit der beflockten Schrumpffolie. Durch Wärmeeinwirkung schrumpft dann die beflockte Schrumpffolie und umspannt faltenfrei den Uberzogenen Gegenstand.When using the flocked shrink film produced according to the invention The objects to be covered are covered with the flocked shrink film. The flocked shrink film then shrinks through the action of heat and wraps around it without wrinkles the coated item.
