Anti-rust coating

Abstract

Disclosed is an anti-rust coating. The anti-rust coating is composed of, by weight part, 25-35 parts of styrene-acrylic emulsion, 1-3 parts of defoamer, 14-18 parts of light calcium carbonate, 7-13 parts of polyvinyl alcohol castor oil, 3-5 parts of emulsifier, 1-2 parts of polypropylene dispersing agent, 13-17 parts of calcium carbonate, 6-8 parts of aluminum oxide, 3-5 parts of m-phenylenediamine, 3-4 parts of anti-corrosion agent, 1-2 parts of sodium acetate, 2-5 parts of vinyl acetate, 1-2 parts of coalescing agent, 2-4 parts of n-butyl alcohol and 2-3 parts of diethyl phthalate. The anti-rust coating has the advantages of being heat-resistant, cold-resistant and high in adhesion force and anti-rust capability.

Description

technical field [0001] The invention relates to an antirust coating, which belongs to the field of coatings. Background technique [0002] Rust is a compound. When iron is in a wet state between rust and rust for a long time, iron will combine with oxygen to produce rust, so iron will rust after a long time. However, iron is a commonly used metal in industry and life, and rust is a headache for people. Rust on iron will reduce its service life, and it is often unhygienic, so using anti-rust coatings on metal surfaces can be effective It can effectively avoid the direct invasion of various corrosive substances in the atmosphere and prolong the service life of metals. However, there are still many defects in the coatings on the market, which need to be updated and refined. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide an anti-rust paint which is high temperature resistant, cold...
