Problems solved by technology

However, this technique is a method of forming a coating film by reacting with heat, and in order to cure the coating film of the heat-curable paint, exposure to heat for a long time is required.
As a result, there is a concern that the plastic material will be damaged and productivity will be reduced.
[0007] In addition, U.S. Patent No. 3,801,368 and No. 5,340,451, European Patent No. 268,821, etc. have proposed a method for electroless plating by sputtering catalyst metal after plasma treatment, but this method has not yet provided Physical properties of coating films used as automotive interior and exterior parts

Abstract

The present invention relates to an ultraviolet-curable coating composition for automotive parts comprising a polyfunctional urethane acrylate oligomer having two or more functional groups; acrylate monomers; resins coated with nano-silica; adhesion enhancers; Sagging control agent and photopolymerization initiator,sagging control agent and photopolymerization initiator; thereby reducing the deterioration of the vapor deposition process and enabling metal plating according to the physical or chemical vapor deposition method, and can be applied to a variety of materials.

Description

technical field [0001] The present invention relates to an ultraviolet curable coating composition for automobile parts. Background technique [0002] In general, since plastic molded products can have various shapes and mechanical properties, the scope of application of plastic molded products as an alternative to metals is spreading. Among such plastic materials, there are cases where the basic physical properties are superior to those of metals. In order to make plastic molded products have a texture similar to metal, a plating process is performed after molding to give luster and appearance such as metal. Such surface plating methods mainly use electroless plating by activating the plastic surface, wet plating by electrolytic plating, or dry plating by vapor deposition in a vacuum state. [0003] According to reports, the wet plating method is carried out by performing electroless plating of nickel (Ni) or copper (Cu) on a plastic molded product that has undergone an e...
