Problems solved by technology

Especially in recent years, the application and substitution of imports in automobiles are expanding and increasing, but domestic putty is hard after curing, difficult to polish, and has a high shrinkage rate, which makes the coating easy to crack and peel off, and the production process is not good. Stability affects the quality and performance of domestic putty

The curing agent comprises, by weight, 35-45 parts of cyclohexanone peroxide, 35-45 parts of benzoyl peroxide, 2-3 parts of acetone, and 13-15 parts of white carbon black.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a kind of putty for automobile repair. Background technique [0002] The official name of putty is polymerized putty, that is, unsaturated polyester resin putty. Because of its unique advantages such as fast curing, easy grinding, less organic solvent emission, strong adhesion, and no cracking, it has become an ideal filling material with active research and rapid development at home and abroad. Widely used in automobile manufacturing, machinery, shipbuilding, locomotives, vehicle manufacturing, and repair industries. Putty is a compound product, which consists of two parts: main agent and curing agent. Agents (such as fumed silica, organic bentonite) are mixed and ground. The curing agent is composed of organic peroxides (such as cyclohexanone peroxide, methyl ethyl ketone peroxide, etc.), and pigments. Putty with excellent performance should have good air-drying properties,...
