Abstract

A metal layer(12) is located between a polyolefin-based carrier film(6) and a facing layer(9) with a printed motif(10) on the inside and an adhesive coating(11) below. The metal layer is formed either by metallizing the carrier film, a metallized plastic film or a metal foil. The printed motif(10) forms a brushed metal sheet structure, which in conjunction with the metal layer gives the appearance of a brushed metal surface. The metal layer may be coated with adhesive(11) on both sides for bonding with the facing layer(9) and carrier film(6).

Description

Die Erfindung betrifft eine mehrschichtige Verbundfolie zur Oberflächenbeschichtung, insbesondere von Blechen, mit einem Schichtenaufbau bestehend aus zumindest
einer durch Koextrusion hergestellten polyolefinischen Trägerfolie, die eine unterseitige Haftvermittlerschicht auf der Basis von Polyolefinen oder Reaktionsharzen und mindestens eine weitere Schicht aus Polypropylen oder einem Polypropylen-Polyolefin-Mischpolymerisat aufweist, und
einer Folie aus einem linearen Polyester (PET) oder aus Polymethylmethacrylat (PMMA) als Deckschicht,
wobei die Deckschicht innenseitig mit einem Druckmotiv bedruckt und mittels einer Klebstoffschicht mit dem unterseitigen Material verbunden ist. Die beschriebene Verbundfolie dient der Oberflächenveredlung von Blechtafeln, Kunststoffplatten, Holzwerkstoffen und dergleichen, die nach ihrer Beschichtung durch Umformung und/oder spanende Bearbeitungen weiter verarbeitet werden. Die fest aufgebrachte Verbundfolie bildet eine dekorative und kratzfeste Oberfläche und ist ausreichend flexibel, so dass ein mit der Verbundfolie beschichtetes Material durch Biege- und Tiefziehverfahren umgeformt werden kann. Eine bevorzugte Anwendung der Verbundfolie ist die Beschichtung von Blechen, die beispielsweise im Automobilbau und bei der Herstellung von Haushaltsmaschinen zum Einsatz kommen.The invention relates to a multilayer composite film for surface coating, in particular of sheet metal, with a layer structure consisting of at least
a polyolefin carrier film produced by coextrusion, which has an underside adhesion promoter layer based on polyolefins or reactive resins and at least one further layer made of polypropylene or a polypropylene-polyolefin copolymer, and
a film made of a linear polyester (PET) or of polymethyl methacrylate (PMMA) as a top layer,
wherein the cover layer is printed on the inside with a print motif and is connected to the underside material by means of an adhesive layer. The composite film described is used for the surface finishing of metal sheets, plastic plates, wood-based materials and the like, which are further processed after being coated by forming and / or machining. The firmly applied composite film forms a decorative and scratch-resistant surface and is sufficiently flexible that a material coated with the composite film can be formed by bending and deep-drawing processes. A preferred application of the composite film is the coating of sheets, which are used, for example, in automobile construction and in the manufacture of household machines.

Eine mehrschichtige Verbundfolie des beschriebenen Aufbaus ist aus EP 0 795 398 B1 bekannt. Das Material kann sowohl in der Deckschicht als auch in der Trägerfolie transparent und/oder pigmentiert sein, wobei außerdem auch eine glänzende oder matte Außenfläche geschaffen werden kann. Bekannt ist es auch, die Deckschicht innenseitig oder außenseitig zu bedrucken oder zwischen der Trägerfolie und der Deckschicht eine Farbdruckschicht anzuordnen ( EP 0 522 240 A2 ). Die bekannten Verbundfo1ien bilden Beschichtungen, die den optischen Eindruck einer lackierten Fläche vermitteln und einer hochwertigen Lackierung gleichwertig sind.A multilayer composite film of the structure described is made EP 0 795 398 B1 known. The material can be transparent and / or pigmented both in the cover layer and in the carrier film, it also being possible to create a glossy or matt outer surface. It is also known to print on the inside or outside of the cover layer or to arrange a color print layer between the carrier film and the cover layer ( EP 0 522 240 A2 ). The well-known composite foils form coatings that give the visual impression of a painted surface and are equivalent to high-quality painting.

Im Modetrend liegen Geräte, die eine metallische Oberfläche aufweisen bzw. deren Oberfläche einer gebürsteten Aluminium oder Edelstahlfläche nachgebildet ist. Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Verbundfolie zur Oberflächenbeschichtung anzugeben, die den metallischen Charakter einer gebürsteten Metallfläche, insbesondere einer gebürsteten Edelstahlfläche, nachahmt.Devices that are in fashion trend a metallic surface have or the surface of one brushed Replicated aluminum or stainless steel surface is. Against this background, the invention is based on the object a composite film for surface coating specify the metallic character of a brushed Metal surface, in particular one brushed Stainless steel surface, imitated.

Ausgehend von einer mehrschichtigen Verbundfolie mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass zwischen der polyolefinischen Trägerfolie und der Deckschicht eine Metallschicht angeordnet ist, die von einer Metallisierung der Trägerfolie gebildet wird oder aus einer metallischen Kunststofffolie oder einer Metallfolie besteht, und dass das Druckmotiv an der Innenseite der Deckschicht die Struktur eines gebürsteten Bleches nachbildet, wobei durch das Zusammenwirken des Druckmotivs und der Metallschicht die Optik einer gebürsteten Metalloberfläche erzeugt wird. Die Metallschicht verleiht der Oberfläche ihren metallischen Glanz. Das Druckmotiv besteht aus einer faserförmigen, in einer Richtung orientierten Struktur, durch welche die durch Bürsten erzeugte Rauhigkeit nachempfunden wird. Das Druckmotiv und die Metallschicht sind durch eine transparente Klebstoffschicht getrennt in unterschiedlichen Schichtenebenen angeordnet. Durch die beschriebene Schichtenanordnung wird ein räumlicher Effekt erzielt, der den typischen metallischen Charakter einer gebürsteten Metalloberfläche erzeugt. Durch die Trägerfolie ist die Verbundfolie ausreichend biegsam und flexibel, so dass das mit der Verbundfolie beschichtete Material durch Tiefziehen oder Kaltverformung weiterverarbeitet werden kann. Durch ihre Deckschicht aus PET oder PMMA ist die Oberfläche kratzfest und hart. Die Deckschicht kann matt oder glänzend ausgebildet werden.Starting from a multilayer Laminated film with the features described above becomes the task according to the invention solved, that between the polyolefinic base film and the top layer a metal layer is arranged by a metallization the carrier film is formed or from a metallic plastic film or There is metal foil, and that the print motif on the inside of the Replicates the structure of a brushed sheet, by the interaction of the print motif and the metal layer the look of a brushed metal surface is produced. The metal layer gives the surface its metallic sheen. The print motif consists of a fibrous, in a directional structure through which the through to brush generated roughness is modeled. The print motif and the metal layer are separated by a transparent adhesive layer in different layer levels arranged. The layer arrangement described creates a spatial Effect achieved the typical metallic character of a brushed metal surface generated. Through the carrier film the composite film is sufficiently flexible and flexible that the material coated with the composite film by deep drawing or Cold forming can be processed further. Through their top layer the surface made of PET or PMMA is scratch-resistant and hard. The top layer can be made matt or glossy.
