Hard low-carbon steel anticorrosive paint for valve and preparation method of hard low-carbon steel anticorrosive pain

Abstract

The invention discloses a hard low-carbon steel anticorrosive paint for a valve. The hard low-carbon steel anticorrosive pain is prepared from the following raw materials in parts by weight: 0.4-1 part of glycolic acid, 2-3 parts of polyamide wax powder, 1-2 parts of sulfosalicylic acid, 10-13 parts of aniline, 0.1-0.4 part of ammonium persulfate, 10-12 parts of pyrrole, 37-40 parts of tetrabutyl titanate, 41-50 parts of n-butyl alcohol, 70-90 parts of butyl cellosolve, 80-90 parts of epoxy resin E40, 5-7 parts of polyamide resin, 0.8-2 parts of dimethicone, 2-3 parts of magnesium stearate, 0.1-0.3 part of trimethylolpropane, 0.5-1 part of 2-thiol benzimidazole, 2-3 parts of zirconium oxychloride octahydrate, 3-4 parts of rosinated alcohol, 0.1-0.2 part of beta-hydroxyalkylamide and a proper amount of 70-75% salpeter solution. The metal passivating ability of the paint is strengthened, a high-compactness oxide film is generated on the surface of low-alloy steel, and the hard low-carbon steel anticorrosive paint has better anticorrosive property.
