ABSTRACT:
Since their surfaces are inactive, polyolefin resins are difficult to plate. A plating method utilizing sensitizing-activation of the surface has been used for plating polyolefin resins. Many attempts have been made to improve the plating properties of the surfaces of polyolefin resins, for example, a mechanical method, a method employing a solvent, a method of coating other types of resins on the surface, etc. As methods modifying the plastics themselves, there are several; a method of introducing polar radicals by graft polymerization, etc., a method of introducing atactic polypropylene or block copolymer of polypropylene and polyethylene, a method of mixing rubber or a copolymer of ethylene and vinyl acetate, a method of mixing in an inorganic filler, etc.
Recently, it was attempted to apply a high chrome etching-catalyst method for plating polyolefin resin, said method being mainly used in the automatic process of plating although the plating adhesion is poorer than that obtained with the plating method of sensitizing-activation. However, there was found no polyolefin resin composition having plating properties that can compare with ABS resin for applying the plating method of a high chrome etching-catalyst method.
We have developed a polyolefin resin composition which can be plated by a high-chrome etching-catalyst method. As a result, we have found that the object of the invention can be attained by blending a compound containing a cyano group with a mixture consisting of polyolefin resin and inorganic filler, and kneading and melting them.
