Description

Deckfolie aus Polyesterharzen und Verfahren zu ihrer Herstellung Die Erfindung bezieht sich auf eine Deckfolie aus Polyesterharz mit eingebettetem Dekor zur Oberflächenveredelung von Bauplatten aus Holz oder dergleichen flächigen Unterlagen und auf ein Verfahren zum Herstellen dieser Deckfolie.Polyester resin cover sheet and process for its manufacture The invention relates to a cover sheet made of polyester resin with embedded decoration for the surface finishing of building panels made of wood or similar flat substrates and to a method for producing this cover sheet.

Mit einem Dekor versehene Melaminharzplatten sind bekannt. Der Nachteil bei diesen Platten besteht darin, daß sie nur in Hochdruckpressen hergestellt werden können und daher in ihren Abmessungen begrenzt sind. Man hat ferner schon Folien aus ungesättigten Polyesterharzen mit eingebettetem Dekor, nämlich bedrucktem Papier, bedrucktem Textilgewebe, Mikroholzfolie usw., hergestellt, die entsprechend der drucklosen Verarbeitung ungesättigter Polyesterharze in langen Bahnen erzeugt werden können. Der Nachteil dieser Polyesterharz-Dekor-Folien ist darin begründet, daß zur Erzielung einer harten, möglichst abriebfesten Oberfläche mit ungesättigten Polyesterharzen gearbeitet werden muß, die nach ihrer Auspolymerisation verhältnismäßig spröde Produkte ergeben. Daher können derartige spröde Dekorfolien im verklebten Zustand auf flächigen Unterlagen plötzliche Stoß- oder Schlagbeanspruchungen nicht elastisch abfangen, so daß es bei derartigen Belastungen sehr leicht zum Reißen der Folie kommen kann.Melamine resin panels provided with a decoration are known. The disadvantage The main thing about these plates is that they are only made in high pressure presses can and are therefore limited in their dimensions. You also have foils made of unsaturated polyester resins with embedded decor, namely printed paper, printed textile fabric, micro wood foil, etc., produced according to the pressureless processing of unsaturated polyester resins in long strips can. The disadvantage of these polyester resin decorative films is based on the fact that to achieve a hard, as possible abrasion-resistant surface with unsaturated Polyester resins must be worked, which proportionally after their complete polymerization result in brittle products. Therefore, such brittle decorative films can be glued Condition on flat surfaces, sudden shock or impact loads are not elastically intercept, so that it is very easy to tear under such loads the slide can come.

Diese Nachteile werden bei der Erfindung dadurch vermieden, daß die Folie an der Oberseite aus harten, abriebfesten Polyesterharzen und an der der Unterlage zugekehrten Unterseite aus weichelastischen Polyesterharzen besteht, wobei innerhalb des Querschnittes der Folie ein allmählicher übergang von harter zu weicher Konsistenz der Polyesterharze vorhanden ist.These disadvantages are avoided in the invention in that the Foil on the top made of hard, abrasion-resistant polyester resin and on the base facing underside consists of flexible polyester resins, with within the cross-section of the film shows a gradual transition from hard to soft consistency the polyester resins is present.

Ein geeignetes Verfahren zum Herstellen dieser Deckfolien besteht gemäß der Erfindung darin, daß ein gegebenenfalls bedruckter Dekor aus Textilgewebe, Papier, Glas- oder Drahtgewebe mit einer instabilen Mischung von harten, spezifisch leichten mit flexiblen, spezifisch schweren Polyesterharzen getränkt wird und daß der satt getränkte Dekor erst nach einer für die Entmischung ausreichenden Zeit, während welcher der harte, leichtere Polyester an die Oberfläche steigt und der flexible, schwerere Polyester nach der Unterseite des Dekors absinkt, zwischen zwei an sich bekannten endlosen, über Walzen geführten profilierten bzw. verchromten Stahlbändern kontinuierlich und unter Anwendung von Druck und Hitze hindurchbewegt wird, wobei die Laufgeschwindigkeit der Bänder und deren Länge so abgestimmt sind, daß beim Austritt aus den Stahlbändern das flächige Produkt auspolymerisiert ist.There is a suitable method for producing these cover sheets according to the invention in that an optionally printed decoration made of textile fabric, Paper, glass or wire cloth with an unstable mixture of hard, specific light is impregnated with flexible, specifically heavy polyester resins and that the richly soaked decor only after a time sufficient for separation, during which the hard, lighter polyester rises to the surface and the flexible, heavier polyester after the bottom of the decor drops, between two per se known endless, profiled or chrome-plated guided over rollers Steel belts moved through continuously with the application of pressure and heat the running speed of the belts and their length are adjusted so that that the sheet-like product is fully polymerized when it emerges from the steel belts.

Entsprechend dem erfindungsgemäßen Vorschlag läßt man die Entmischung und die anschließende Auspolymerisation auf dem eingebetteten Dekor vor sich gehen, wobei der Dekor nach oben weist. Die vorher durch kräftiges Rühren oder sonstige Mittel homogenisierte instabile Harzmischung entmischt sich vor der Auspolymerisation so, daß die fertige Platte einen Aufbau weich zu hart von unten nach oben aufweist.According to the proposal according to the invention, the separation is allowed to take place and the subsequent polymerisation on the embedded decor takes place, with the decor facing up. The previously by vigorous stirring or other Medium homogenized unstable resin mixture segregates before polymerization so that the finished plate has a structure soft to hard from bottom to top.
