Definitions
- the present invention relates to a novel, multi-layer composite material and a method for producing this layer composite material.
- Layered composite materials or molded parts made from these layered composite materials are used on a large scale and for a wide variety of technical purposes.
- a large number of frequently decorative shaped parts such as, for example, panels, keyboards, switches, instrument panels or parts of the interior trim of motor vehicles, etc., are produced from such composite materials.
- cover layer or cover film which consists, for example, of polycarbonate.
- Polycarbonate cover films in particular are characterized by the fact that they allow a visually appealing surface appearance of the molded body and also have advantageous properties with regard to scratch resistance, shock resistance, transparency, etc.
- Such plastic films in particular colored or scattered light films, have been known for a long time and are used, for example, in automobile manufacture in the production of front panels, switch covers illuminated from the inside or identification plates, e.g. for control switches of motor vehicle heating or air conditioning systems used.
- the symbols and / or inscriptions are applied in a manner known per se, for example in a screen or multiple screen printing process.
- the surface exposed or directly exposed to the direct influences that is to say the cover layer of the molded part or of the composite material, is integrally bonded to the base part.
- the base part or the base or carrier layer provides the necessary structural strength or dimensional stability of the three-dimensionally shaped molded part.
- the previously known composite materials which are used in particular in the electrical, electronics and automotive industries and, for example, have decorative surfaces with the required properties, usually consist of a film layer, for example made of polycarbonate (PC) or acrylic butadiene Styrene copolymers (ABS-CoPo), and a carrier layer made of the same material, i.e. also made of PC or ABS-CoPo.
- the cover film or scattered light film which may have been colored or otherwise decorative in a previous work step, is connected, for example with heat treatment, to the carrier material, or the carrier material is applied to the back of the cover film by back injection.
- composite materials of this type used hitherto have serious disadvantages.
- the fact that identical materials have to be used to provide the composite material described above or the resulting shaped bodies or to ensure a firm bond between the carrier and cover film leads to the obtaining of three-dimensional shaped bodies with a very high weight. This is due to the relatively high density of the support materials used, such as polycarbonate.
- the high weight of the carrier material and thus of the entire composite material is particularly disadvantageous in the automotive industry because, for example, it has a disadvantageous effect on the gasoline consumption of the motor vehicle and thus endangers the economy.
- the known composite materials made of PC and ABS-CoPo are still in need of improvement with regard to their chemical resistance and their recyclability compared to other materials.
- Another disadvantage of conventional composite materials is the relatively high price of the carrier materials used. Furthermore, the processing properties of the materials used as carrier material, such as, for example, polycarbonates, can be modified only to a limited extent, or to a limited extent, in comparison to other thermoplastic polymers, such as, for example, polyethylene or polypropylene.
- thermoplastic polymers such as, for example, polyethylene or polypropylene.
- the object of the present invention was therefore to remedy the disadvantages described and to provide a qualitatively improved composite material which can be deformed very well in two and three dimensions and, because of the firm adhesion between the layers, has very high mechanical stability.
- the aforementioned objects are achieved by the provision of a layered composite material, the characteristic features of which can be seen in the fact that the composite material at least:
- thermoplastic plastic arranged on the heat-hardened layer, the thermoplastic in the top layer being selected from the group comprising polycarbonates, acrylic butadiene Styrene copolymers, poly (butylene) terephthalates, polyesters and derivatives and mixtures of the aforementioned materials.
- the layer arrangement or combination of materials according to the invention ensures excellent adhesion between the layers within the composite material, and thus the connection of thermoplastic material selected from the group comprising polycarbonates, acrylic butadiene
- the carrier material used in the previously known composite materials with the above-mentioned disadvantageous properties can be completely dispensed with.
- the composite material according to the invention or the molded parts produced therefrom show a very high mechanical stability and have the desired surface properties. They are also significantly lighter than the corresponding, previously known molded parts. Since the carrier material of the multilayer composite according to the invention is polyolefinic polymer materials and particularly preferably polypropylene instead of e.g. Includes polycarbonate, the production of the composite material according to the invention is also significantly cheaper and more economical.
- the cover layer of the composite material according to the invention can be a commercially available plastic film made of a thermoplastic, the plastic being selected from the group comprising polycarbonates, acrylic-butadiene-styrene copolymers, poly (butylene terephthalate) s, polyesters and derivatives and mixtures of the aforementioned materials ,

They can form the cover layer alone or in a mixture with other plastics which are compatible therewith. Examples of such compatible plastics include certain polyesters. They can be present in the mixture in proportions of up to 90% by weight, preferably up to 50% by weight. Compatibility is given when the mixture in the form of a film is clear or almost clear and transparent.

- the cover layer of thermoplastic material according to the invention which is also referred to below as cover film or scattered light film, is preferably refined by printing or metallizing.
- cover film or scattered light film is preferably refined by printing or metallizing.
- the good printability of, for example, polycarbonate films, in principle enables one or more layers of color or the decoration to be applied, preferably to the underside of the film, so that the color or the decor remains visible through the transparent film layer after lamination and at the same time is protected against abrasion or other damage.
- the cover layer is made of a translucent or transparent material. The finishing or application of color layers to the translucent cover layer or cover film, for example, is carried out according to methods known per se.
- certain color effects or certain markings are produced on the cover film with the aid of screen printing processes by applying one or more, if appropriate, color coatings that can be screened.

- the weight of the heat-cured layer, which preferably comprises a resin is preferably between 10 and 200 g / m 2 , in particular between 15 and 150 g / m 2 and particularly preferably between 30 and 80 g / m 2 .
- a resin-impregnated nonwoven, fabric, paper or a resin-impregnated film made of a thermoplastic is used as the heat-hardened layer.
- Resins suitable for this include acrylate resins, phenolic resins, urea resins and melamine resins.
- the composite material according to the invention further comprises at least one intermediate layer which contains at least one thermoplastic polymer material.
- the intermediate layer provided according to the invention is preferably arranged between the heat-hardened layer and the polyolefinic carrier layer.
