Method for Manufacturing a Vehicle Outer Surface Component and Vehicle Outer Surface Component

Abstract

The invention relates to a method for producing a vehicle outer surface component (1) comprising the following steps: preparing a base component (2) 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 (4) of a scratch self-healing plastic material into the closed injection mold to coat the base component (2); the invention further relates to a vehicle outer surface component, in particular a vehicle outer surface component produced according to this method.

Claims

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 material formed dependent on a glass point to provide a scratch self-healing plastic into the closed injection mold to coat the base component.

2. The method according to claim 1, wherein the step of injecting a covering layer is by injecting a PUR (polyurethane) or PUA (polyurea) having 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 step of injecting the covering layer, includes the step of applying an intermediate layer or a functional layer to the base component in the injection mold, and applying the covering layer to the intermediate layer or functional layer.

5. The method according to claim 4, further including forming the base component and/or the intermediate layer or functional layer as transparent, translucent or colored and/or forming as having a smooth, grained or structured surface and/or forming as having text or a graphic pattern.

6. The method according to claim 1, further including producing the base component as a structured surface and the covering layer is clear.

7. The method according to claim 4, 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, further comprising the step of colorizing the covering layer.

9. A vehicle outer surface component, comprising: at least a base layer made of a thermoplastic material and a covering layer, wherein the covering layer is produced from a material formed dependent on a glass point to provide a scratch self-healing plastic.

10. The vehicle outer surface component according to claim 9, wherein the covering layer is produced from PUR (polyurethane) or PUA (polyurea) and has a high-gloss surface and/or is 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 a 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 the component is a pillar molding or a door sill panel.

15. The vehicle outer surface component according to claim 9, produced by the method according to claim 1.

16. The vehicle outer surface component according to claim 9, wherein the component is a fixed or movable cover for a roof module.

17. The vehicle outer surface component according to claim 9, wherein the component is transparent.

18. The method according to claim 1, wherein the step of injecting a covering layer is by injecting a PUR (polyurethane) having a Shore hardness ranging from 65 Shore A to 80 Shore D.

19. The method according to claim 1, wherein the step of injecting a covering layer is by injecting a PUR (polyurethane) having a glass transition temperature (Tg) ranging from 40 to 60 C.

20. The vehicle outer surface component according to claim 9, wherein the covering layer is produced from PUR (polyurethane) having a Shore hardness ranging from 65 Shore A to 80 Shore D.

21. The vehicle outer surface component according to claim 9, wherein the covering layer is produced from PUR (polyurethane) having a glass transition temperature (Tg) ranging from 40 to 60 C.

Description

[0025] In the following, the invention will be specified in greater detail in the context of embodiment examples of a vehicle outer surface component according to the invention, with reference to the set of drawings. The drawings show:

[0026] FIG. 1 a sectional view of a vehicle outer surface component according to the invention; and

[0027] FIG. 2 a sectional view of another vehicle outer surface component.

[0028] FIG. 1 shows a schematic sectional representation of a vehicle outer surface component 1, e.g. in the form of a cover for a roof module. A base layer 2 made of a thermoplastic material is formed with a structured upper side 3 or surface. Base layer 2 is coated with a covering layer 4 which is made of a self-healing plastic, e.g. PUR or PUA, and particularly comprises clear plastic, so that structured upper side 3 is transparent. Surface 5 of covering layer 4 may be formed as smooth and high-gloss or also as structured.

[0029] A vehicle outer surface component 1 as shown in FIG. 2 contains, on base layer 2, an intermediate layer or functional layer 6, onto which covering layer 4 is applied. Intermediate layer or functional layer 6 contains, e.g. heating wires 7 of a heating device.

[0030] The individual features of the invention disclosed in the description in the context of the embodiment examples and in the figures may be combined in any technically expedient arrangements and configurations with the subject matter of the invention in its general form.
