説明
This paper describes the research on etching mechanism for coating of polypropylene resin. After pre-etching with xylene and etching with chromic-sulfuric acid mixture at 60°C, the resin was examined by weight loss, surface roughness, and crystallinity.<br>The results of experiments were summarized as follows:<br>(1) The weight loss by etching increased with the progress of pre-etching time. It was believed that the degree of swelling of the resin surface and the dissolution of small molecules from the surface increased with the increase of pre-etching time. The results revealed that the resin surface was more easily etched by the subsequet acid etching.<br>(2) In the standard type of polypropylene resin, the curve representing the relation between surface roughness and etching time was found to show a maximum roughness, but the same curve in the plating type of polypropylene resin was found to be linear.<br>(3) No carbonyl radicals were formed on the resin surface layer etched under the same conditions.<br>(4) Crystallinity of the resin was reduced by etching, which was assumed to be owing to the cutting of principal chains of crystalline molecules and their dissolution by etching.<br>(5) The adhesion of the standard type of polypropylene resin was poor owing to the effects of blisters and skips.<br>(6) The adhesion of the plating type of polypropylene resin increased during the first 60 minutes, and then, decreased with the lapse of time.
