Abstract

A method for producing a vehicle outer surface component having steps for preparing a base component made of a thermoplastic material in an injection mold by injecting a thermoplastic material into the injection mold or by placing a prefabricated base component made of a thermoplastic material therein, and injecting a covering layer of a scratch self-healing plastic material into the closed injection mold to coat the base component. A vehicle outer surface component is also provided, in particular a vehicle outer surface component, produced according to this method.

First claim

1 . A method for producing a vehicle outer surface component, comprising:
preparing a base component made of a thermoplastic material in an injection mold by injecting a thermoplastic material into the injection mold or by placing a prefabricated base component made of a thermoplastic material therein and injecting a covering layer of a scratch self-healing plastic material into the closed injection mold to coat the base component.

2 . The method according to claim 1 ,
wherein the plastic material of the covering layer is a PUR (polyurethane) or PUA (polyurea) and is produced in particular with a high-gloss surface.

3 . The method according to claim 1 , wherein the PUR or PUA is a UV-resistant plastic material.

4 . The method according to claim 1 , wherein before the covering layer is injected, an intermediate layer or functional layer is applied to the base component in the injection mold, and the covering layer is applied to the intermediate layer or functional layer.

5 . The method according to claim 1 , wherein the base component and/or the intermediate layer or functional layer is formed as transparent, translucent or colored and/or is formed as having a smooth, grained or structured surface and/or is formed as having text or a graphic pattern.

6 . The method according to claim 1 , wherein the base component is produced as having a structured surface and is covered by a clear covering layer.

7 . The method according to claim 1 , wherein the intermediate layer or functional layer contains at least one light guide or is formed as a light guide layer, is a design layer or a touch-sensitive layer for generating a signal, or contains an antenna device or heating wires, or is formed at least in a partial area as a three-dimensional structure.

8 . The method according to claim 1 , wherein the covering layer is colorized.

9 . A vehicle outer surface component having a layered, comprising: at least a base layer made of a thermoplastic material and a covering layer, wherein the covering layer is produced from a scratch self-healing plastic material.

10 . The vehicle outer surface component according to claim 9 , wherein the covering layer is produced from PUR (polyurethane) or PUA (polyurea) and is particularly formed as high-gloss and/or as UV-resistant.

11 . The vehicle outer surface component according to claim 9 , wherein an intermediate layer or functional layer is positioned between the base layer and the covering layer.

12 . The vehicle outer surface component according to claim 9 , wherein the covering layer is applied as an injection molded layer onto the base layer or the intermediate layer or functional layer in an injection mold.

13 . The vehicle outer surface component according to claim 9 , wherein the functional layer is a light guide layer or at least contains a light guide, is a design layer or a touch-sensitive layer for generating a signal, or contains an antenna device or heating wires.

14 . The vehicle outer surface component according to claim 9 , wherein it is a pillar molding, a door sill panel or a fixed or movable, particularly transparent cover for a roof module.

15 . The vehicle outer surface component according to claim 9 , wherein it is produced by a method according to claim 1 .
