Putty with good sanding property

Abstract

The invention discloses putty with a good sanding property, which is formed through the hybrid reaction of main agent and curing agent. The mass ratio of the main agent to the curing agent is 100:2; the main agent comprises the following components by part by weight: 56 to 64 parts of unsaturated polyester resin, 4 to 8 parts of phenethylene, 10 to 15 parts of talcum powder, 5 to 8 parts of barium sulphate, 2 to 3 parts of titanium dioxide, 6 to 9 parts of heavy calcium carbonate, 0.5 to 1 parts of tertiary butyl hydroquinone, 1.4 to 1.8 parts of anti-settling agent, and 0.2 to 0.4 part of accelerating agent; and the curing agent comprises the following components by part by weight: 80 to 84 parts of benzoyl peroxide, 5 to 8 parts of pigment, 10 to 12 parts of filling material, and 5 to 6 parts of 10 percent dimethyl aniline.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an atomic ash with good grinding performance. Background technique [0002] Atomic ash is mainly used for repairing and painting primers of various vehicles, machine tools, ships, instruments, instrument shells and furniture. At present, the production technology of atomic ash is basically mature, and whether the atomic ash is easy to polish after forming a film has become an important issue. It is an important index to evaluate the product quality of putty manufacturers. [0003] At present, in order to improve the grinding performance of putty after film formation, many manufacturers have adopted various methods: for example, reducing the viscosity of unsaturated polyester resin, while reducing the viscosity of the resin, the risk is high, and it is easy to reduce the activity of the resin. Even putty film formation and cracking; some add mono-acid or fumaric acid substances i...
