METHOD OF PAINTING PLASTIC PARTS OF AUTOMOBILE

摘要

PURPOSE: A coating method of automotive plastic parts is provided to remarkably improve the adhesion and the scratch resistance of a film, to embody elasticity enough to protect the surface of a film, and to increase the strength of the surface of a film. CONSTITUTION: A coating method of automotive plastic parts comprises a step of spreading a paint composition for a primer on a plastic component, and a step of spreading a base paint composition on a primer film. The paint composition for a primer comprises 10-30 weight% of a chlorine-modified acryl resin, 1-20 weight% of an acrylic resin, 1-20 weight% of an epoxy modified acryl resin, 01-20 weight% of a chlorinated polypropylene, 0.1-20 weight% of a hardener, and a 10-80 weight% of solvent. The base paint compostion comprises 30-55 weight% of a polyester-polycarbonate based polyurethane resin, 2-20 weight% of a hardener, 1-10 weight% of quencher, 1-15 weight% of a precipitation inhibitor, 0.5-2 weight% of a photostabilitzer, and 20-70 weight% of solvent .
