Abstract

The invention provides a kind of white paint composition, contains chemical plating catalyst precursor, binding agent, solvent in the described white paint composition, contains or does not contain additive; Described chemical plating catalyst precursor is selected from SnO2, ZnSnO3 , ZnTiO3 at least one. The invention also provides a method for selectively metallizing the surface of an insulating substrate by using the white paint composition and a composite product obtained by the method. The white coating composition provided by the invention can meet the requirements of white products; at the same time, the white coating composition is used to form a white coating on the surface of the insulating substrate without any influence on the various properties of the insulating substrate itself. After that, direct electroless plating on the coating surface can be realized, so as to realize selective metallization and obtain composite products with good adhesion.

Description

technical field [0001] The invention belongs to the field of surface metallization of non-metallic materials, and in particular relates to a white paint composition, a method for selectively metallizing the surface of an insulating substrate by using the white paint composition, and a composite product obtained by the method. Background technique [0002] A metal layer is formed on the surface of the plastic as a channel for electromagnetic signal transmission. It has been widely used in automobiles, industries, computers, communications and other fields. The selective formation of a metal layer on the plastic surface is a core link in the manufacture of such plastic products. There are many methods for plastic surface metallization production lines. In the prior art, metal nuclei are generally formed on the surface of the plastic substrate as the catalytic active center of electroless plating, and then electroless plating is performed. [0003] For example, the applicant's...
