Abstract

The invention relates to primer-topcoat paint for automobile parts. The primer-topcoat paint consists of a main coating agent component A and a curing agent component B, wherein the main coating agent component consists of base resin, a pigment filler, a solvent and an aid; the base resin consists of epoxy resin 634-80 and epoxy resin 601-75 in the weight ratio of 20-35:10-19; and the base resin accounts for 30 to 54 percent of the weight of the main coating agent. The primer-topcoat paint has high adhesion, high mechanical strength, high corrosion resistance, high medicament resistance, highacid rain resistance, high pollution resistance and high moisture resistance. A coating is free from foaming, color change and distortion under a high-temperature and high-humidity climate condition,has high construction performance and high production line overcoatability.

Description

technical field [0001] The invention relates to a paint, in particular to a bottom-surface-in-one paint for auto parts and a preparation method thereof. Background technique [0002] With the rapid development of the domestic automobile industry, the auto parts paint used to improve the pollution resistance and salt spray resistance of auto parts has also been vigorously developed and manufactured by the majority of paint manufacturers. Although the existing auto parts paint is salt-resistant The fog performance has been greatly improved, but due to the huge amount of paint used for auto parts, it is extremely inconvenient to waste time and energy if the traditional primer and top coat are applied separately. Or improper use of raw materials often makes its salt spray resistance, pollution resistance, impact resistance, flexibility and other properties not reach the best state. Contents of the invention [0003] In order to solve the problems of inconvenient use and unsat...
