PURPOSE:To metallize the surface of a molding consisting of a polyphenylene sulfide resin and inorg. filler by roughening the surface of said molding with a specific chloride dissolved in an org. solvent then subjecting the surface to electroless plating. CONSTITUTION:The powdery inorg. filler such as alumina, silica, magnesia or others having 0.5-10mu average grain size is added at 10-250pts.wt. to 100pts. wt. polyphenylene sulfide resin and after the mixture is kneaded by a screw extruder, etc., the mixture is molded to a desired shape by an injection molding machine, extrusion molding machine and other methods. The molding is then immersed into the liquid of 60-80 deg.C prepd. by dissolving 5-20g chloride type Friedel-Crafts reaction catalyst such as anhydrous aluminum chloride into 100cc org. solvent such as benzene or toluene to dissolve the filler on the surface and to etch the surface, by which the surface is roughened. After such molding is rinsed, the plating layer having the excellent adhesiveness to the plating film is formed thereon by an electroless plating method to metallize the surface. |
