Abstract

The invention belongs to the field of paint, relates to PU (Poly Urethane) double-component plastic paint, and in particular relates to PU double-component plastic paint which is applied to automobile trim plastic and rubber components. The automobile trim PU double-component plastic paint consists of a component A and a component B, wherein the component A comprises resin, 2-4 parts of high pigment carbon black dye, 3-5 parts of carbon black dispersing agent, 0.5-1 part of anti-settling agent, 0.02-0.05 part of drying agent, 0.5-1 part of flatting agent, 0.2-0.5 part of defoaming agent, 5-7 parts of matting agent, 1-2 parts of wax powder and 20-25 parts of a solvent, and the resin is a mixture consisting of 10-15 parts of high-hydroxy acrylic acid resin, 20-25 parts of low-hydroxy acrylic acid resin and 20-30 parts of quick-drying hydroxy acrylic acid resin; the component B consists of 70-90 parts of aliphatic polyisocyanate and 10-30 parts of n-butyl acetate. The paint can meet the property requirements (good adhesion capability, good chemical product resistance and laser etching possibility) of automobile trim plastic products.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a PU two-component plastic paint, in particular to a PU two-component plastic paint for automotive interior plastic parts. Background technique [0002] With the rapid development of the automobile industry, the application of various coatings in the automobile industry is becoming more and more extensive. The application of plastic materials in the automobile industry is increasing. Protection and decoration are also extremely important. In order to obtain better visual effects, enhance the chemical resistance of the plastic surface and prolong its service life, it is necessary to spray a layer of paint on the surface of the plastic material to improve the quality of the plastic product. [0003] At present, the paints used in automotive interior plastic products are mainly imported, and the unit price is high, resulting in high manufacturing costs; the chemical resistance of domestic pain...
