COATING COMPOSITION FOR AN VEHICLE PARTS, PAINTING METHOD FOR VEHICLE PARTS AND VEHICLE PARTS USING THE SAME

摘要

The present invention relates to a coating composition for vehicle parts, and a coating method for vehicle parts and vehicle parts using the same. In an embodiment, the coating composition for vehicle parts comprises: a main agent containing 50-70 parts by weight of an acryl polyol resin, 0.1-0.5 parts by weight of an adhesion enhancer, 0.01-1.0 parts by weight of a pigment, 0.1-1.5 parts by weight of a reaction catalyst, 0.5-8.0 parts by weight of additives and 20-40 parts by weight of a solvent; and 10-30 parts by weight of a curing agent containing a resin for a curing agent and a solvent for a curing agent. The acryl polyol resin is a blend of a non-reactive acryl polyol resin and a reactive acryl polyol resin at a weight ratio of 1:1.5-1.5:1, and the resin for a curing agent is used in an amount of 5-20 parts by weight based on 100 parts by weight of the main agent, and the solvent for curing agent is used in an amount of 5-15 parts by weight based on 100 parts by weight of the main agent. According to the present invention, it is possible to realize a beautiful and light color while maintaining a metallic texture of chrome plating, to control various designs, colors and gloss, to ensure the reliability required for an interior part for vehicles so that the part may have a desired function and high quality, to improve the product value of an interior part of vehicles, to provide sun cream resistance, scratch resistance and wear resistance, and to simplify the conventional secondary and tertiary coating systems into a mono-coating system, thereby reducing the cost and total processing cost.
