Die Erfindung betrifft ein Verfahren zur Herstellung eines komplexen Materials mit dem Aussehen eines Spiegels, wobei der Komplex einen Träger aus thermoplastis ehern Material, eine Klebeschicht oder Klebstoffschicht und eine durchsichtige Folie oder einen durchsichtigen Film aus Kunststoff, der auf einer Seite metallisiert ist, aufweist und der Träger und die Folie so angeordnet sind, daß die metallisierte Seite der Folie gegen den Träger gerichtet ist.The invention relates to a method of manufacture a complex material with the appearance of a mirror, the complex being a carrier made of thermoplastic material, an adhesive layer or adhesive layer and a transparent foil or a transparent film made of plastic, which is metallized on one side, has and the carrier and the foil are arranged so that the metallized side of the foil is directed towards the carrier is.

Es ist ein Verfahren zur Herstellung eines Komplexes, der einen Träger aus Polyvinylchlorid, eine Klebstoff schicht und eine metallisierte Folie aus Polyalkylenterephthalat aufweist, z.B. aus der US-PS2 7o2 58o bekannt.It is a method of making a complex that consists of a polyvinyl chloride carrier, an adhesive layer and a metallized film of polyalkylene terephthalate known for example from U.S. Patent No. 2,7o2,580.

Bei diesem kontinuierlich ausgeführten Herstellungsverfahren wird der biegsame Träger z.B. aus Polyvinylchlorid mit einem geeigneten KlebstoffUberzug in einem Lösungsmittel überzogen, wobei das Lösungsmittel darauf durch eine Wärmequelle, welche die Klebstoffschicht bei erhöhter Temperatur trägt, abgedampft wird. Eine Folie aus Polyalkylenterephthalat, die gemäß dem Fachmann bekannten Arbeitsweisen metallisiert ist, wird dann die metallisierte Seite der Folie gegen den Träger gerichtet, durch eine erhitzte Druckwalze in Berührung mit dem Klebstoff gebracht,wobei der so erhaltene Schichtstoff darauf gekühlt und auf Spulen gewickelt wird.In this continuous manufacturing process, the flexible support is made of polyvinyl chloride, for example coated with a suitable adhesive coating in a solvent, the solvent thereon by a heat source, which carries the adhesive layer at an elevated temperature, is evaporated. A film made of polyalkylene terephthalate, which is metallized according to the procedures known to the person skilled in the art, the metallized side of the film is then opposed directed the carrier, brought into contact with the adhesive by a heated pressure roller, the resulting Laminate is cooled on it and wound on spools.

Das gemäß diesem Verfahren erhaltene Produkt besitzt jedoch einen wesentlichen Nachteilt seine Oberfläche weist eine große Anzahl von punktförmlgen Unregelmäßigkeiten oder Streifen bzw. Riefen auf, welche das Produkt für solche Zwecke wie die Spiegelherstellung unbrauchbar macht. Man hat lange Zelt versucht, diese Art von Komplex zu vervoll-The product obtained according to this process, however, has a significant disadvantage in that it has a surface a large number of punctiform irregularities or stripes or grooves, which the product for such Purposes like making mirrors useless. Long attempts have been made to complete this type of complex-

kommnen, um daraus Spiegel herzustellen, ohne daß dies bisher gelungen ist.come to make mirrors out of them, without having done this up to now succeeded.

Das Verfahren gemäß der Erfindung ermöglicht es, diese Nachteile zu überwinden. Das Verfahren gemäß der Erfindung ist dadurch gekennzeichnet, daß man das komplexe Material in eine Presse einführt, deren erhitzte Platten einen fehlerlosen Oberflächenzustand aufweisen, während eines Zeitraums zwischen Io und 2o min mit einem Druck unterhalb 2o bar preßt, wobei die Temperatur der Platten über dem Vicat-Punkt des Trägers liegt, das komplexe Material dann mit einem Druck zwischen 25 und 9o Bar während eines Zeitraums über 2ο min preßt, wobei die Platten der Presse fortschreitend bis auf Umgebungstemperatur gekühlt werden.The method according to the invention makes it possible to overcome these disadvantages. The method according to the invention is characterized in that the complex material is introduced into a press, its heated plates have a flawless surface condition for a period of time between Io and 20 min with a pressure presses below 2o bar, the temperature of the plates being above the Vicat point of the carrier, the complex material then with a pressure between 25 and 9o bar for a period of 2ο min, pressing the plates the press can be progressively cooled down to ambient temperature.

Durch die Anwendung dieses Verfahrens erhält man einen Komplex mit dem Aussehen und den reflektierenden Eigenschaften eines Spiegels, wobei dieser Eigenschaften der Materialien hat, aus denen er zusammengesetzt ist (Weichheit, keine Gefahr eines Schneidens, reflektierende Oberfläche geschützt durch die Folie oder den Film usw.)By using this process, a complex is obtained with the appearance and the reflective Properties of a mirror, which has properties of the materials from which it is composed (Softness, no risk of cutting, reflective surface protected by the foil or film, etc.)

Ganz allgemein kann jede Art von thermoplastischem Träger bei der Durchführung des Verfahrens gemäß der Erfindung Anwendung finden: Es genügt, daß der Träger sich bei den Arbeitstemperaturen deformiert. Man kann z.B. Polystyrol, Polyvinylchlorid, Acrylnitrilstyrol-butadien-copolymer, Methylstyrol-butadien-polymethacrylat usw. verwenden. Ebenso ist jede Art von durchsichtiger Folie oder durchsichtigem Film geeignet: Polyäthylenterephthalat (polyterephthalate d*ethylene glycol), Polyäthylen, Polypropylen, ■etallisierte Cellulosefolie usw. Vorzugsweise ist diese Folie oder dieser Film ein Material, das eine Neigung zum Hirten in der Wärme hat . und das Temperaturen oberhalb loo°C auehält, ohne sich zu deformieren.In general, any type of thermoplastic carrier can be used in carrying out the method according to the invention Application: It is sufficient that the carrier deforms at the working temperatures. For example, you can use polystyrene, Polyvinyl chloride, acrylonitrile styrene butadiene copolymer, Use methyl styrene butadiene polymethacrylate, etc. Likewise, any type of transparent film or transparent Suitable for films: polyethylene terephthalate (polyterephthalate d * ethylene glycol), polyethylene, polypropylene, ■ Metallized cellulose sheet, etc. Preferably, this sheet or film is a material that has a tendency to Shepherds in warmth. and that maintains temperatures above 100 ° C without deforming.

809811/0862809811/0862

Es ist festgestellt worden, daß man sehr gute Ergebnisse erhält, wenn man einen Träger wählt, der sich bei der Arbeitstemperatur deformiert, solange wie die Folie oder der Film sich nicht deformiert, derart, daß der Träger sich ausstreckt und die vollkommen polierte Form der Pressenplatte annimmt.It has been found that very good results are obtained if one chooses a carrier that is compatible with the working temperature deforms, as long as the foil or the film is not deformed, in such a way that the carrier extends and takes on the perfectly polished shape of the press platen.

Da die gewöhnlich verwendeten Pressen keine genügend polierten Oberflächen haben, schaltet man allgemein eine Glasplatte oder eine Metallplatte ein, die das Aussehen eines polierten Spiegels ("poli-miroir") hat, der sorgfältig vor dem Gebrauch gereinigt ist, um die oberflächlichen Verunreinigungen ebenso wie Spuren von Feuchtigkeit, von Fett usw. auszuschalten. .Since the commonly used presses do not have sufficiently polished surfaces, one is generally switched on Glass plate or a metal plate that has the appearance of a polished mirror ("poli-miroir"), which is carefully is cleaned before use to remove superficial impurities as well as traces of moisture To switch off fat, etc. .

Die Temperatur, bei welcher das komplexe Material gemäß der Erfindung verwirklicht wird, darf nicht unterhalb der Erweichungstemperatur des Trägers (d.h. dem Vicat-Punkt, der durch die französische Norm NF T 51 o21 definiert ist) liegen. Der mit der Presse angewendete Druck muß ausreichend sein, um eine Deformation des erweichten Trägers zu erhalten, während die Dauer, während welcher das komplexe Material einem Druck unterworfen ist, nicht weniger als Io min sein kann. Wenn diese Gegebenenheiten nicht beachtet werden, kann man kein komplexes Material mit dem Aussehen eines Spiegels erhalten.The temperature at which the complex material according to the invention is realized must not be below Softening temperature of the support (i.e. the Vicat point, which is defined by the French standard NF T 51 o21). The pressure applied with the press must be sufficient be to obtain a deformation of the softened wearer during the period during which the complex Material under pressure cannot be less than Io min. If these conditions are not observed one cannot get a complex material with the appearance of a mirror.

Vas die benutzten Klebstoffe betrifft, so kann man jeden Klebstoff, der dem Sachverständigen bekannt ist, nehmen, um die verschiedenen Komplex· zu verwirklichen (in dem Maß, in dem sie sich nicht bei den Arbeltstemperaturen zersetzen), wie die Polyvinylacetat·, Polyvinylidenchlorid, Polyesterlacke usw.Regarding the adhesives used, any adhesive known to the expert can be used, to realize the various complexes (to the extent that they do not decompose at working temperatures), such as polyvinyl acetate, polyvinylidene chloride, polyester varnishes, etc.

Gemäß einem anderen Merkmal des Produkts gemäß der Erfindung weist dieses eine Dicke der metallisierten Folie oder des metallisierten Films auf, die niedriger als loo Mikron ist. Man muß dieser Dicke tatsächlich Rechnung tragen, weil es sonst nicht möglich ist, eine ausreichende Verformung des thermoplastischen Trägers zu erhalten und bei dem erhaltenen Produkt die notwendigen reflektierenden Eigenschaften zu erzielen.According to another characteristic of the product according to the invention, it has a thickness of the metallized foil or the metallized film that is less than 100 microns. You actually have to take this thickness into account wear, because otherwise it is not possible to obtain sufficient deformation of the thermoplastic carrier and to achieve the necessary reflective properties in the product obtained.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert.The invention is explained in more detail below with reference to the drawing.
