Definitions
- the present invention relates to composite bodies containing a polyurethane base body and a surface coating thereon, wherein the surface coating consists of thermoplastic polyurethane having a thickness of 5 to 1000 microns. Furthermore, the present invention relates to a method for producing composite bodies according to the invention and the use of composite bodies according to the invention as interior parts in automobiles or as shoe soles.
- polyurethanes are often used to produce objects whose visible properties make the polyurethane surface visible to the user and partially touched directly by the user.
- Such items are, for example, interior parts of motor vehicles, such as steering wheels, instrument panels, door panels or shoe soles.
- polyurethane base bodies are often painted.
- the coating of polyurethane base bodies can be carried out, for example, after the preparation of these parts by spraying the paint or immersing the polyurethane base in the paint. It is also possible to apply the lacquer layer by means of what is known as in-mold coating, in which a lacquer is introduced into a mold, which is then filled with the polyurethane reaction mixture After the polyurethane reaction mixture has hardened, the finished lacquered polyurethane molded part is removed from the mold.
- a disadvantage of these techniques for applying a lacquer layer to a polyurethane base is that they are in each case quite complicated processes. Thus, when immersing polyurethane base bodies in a coating bath, a desired uniform lacquer coating is obtained only if the polyurethane base resin body is a small, simply shaped object and this is removed from the paint bath at a precisely controlled speed.
- IT 1,334,840 proposes placing a carrier film coated with a lacquer in the mold and then adding the polyurethane reaction mixture to the mold.
- lacquered polyurethanes are manifold. Thus, these often had porous paint surfaces, which are easily polluted.
- the mechanical stability, for example the adhesion or the elasticity of the paints is inadequate, especially for automotive applications.
- the resistance of the paints to solvents is often poor and the UV stability of the paint systems is inadequate, especially in automotive applications.
- Lacquered polyurethanes are described, for example, in "Kunststoffhandbuch, Volume 7, Polyurethanes", Carl Hanser Verlag, 2nd edition 1983, Chapter 7.3.3.5.
