Anticorrosive paint for flame-retardant low-carbon steel valve and preparing method thereof

Abstract

The invention discloses an anticorrosive paint for a flame-retardant low-carbon steel valve. The anticorrosive paint is prepared from, by weight, 0.1-0.2 part of dibasic lead phosphite, 0.8-1 part of calcium ricinoleate, 1-2 parts of ethoxylated alkyl ammonium sulfate, 1-2 parts of sulfosalicylic acid, 10-13 parts of phenylamine, 0.1-0.4 part of ammonium persulfate, 10-12 parts of pyrrole, 41-50 parts of n-butyl alcohol, 70-90 parts of butyl cellosolve, 80-90 parts of epoxy resin E, 5-7 parts of polyamide resin, 0.8-2 parts of dimethicone, 3-4 parts of hydrous zinc borate, 0.4-1 part of ammonium molybdate, 1-2 parts of ammonium polyphosphate, 0.8-1 part of linoleic acid, 0.5-1 part of fatty acid polyglycol ester, 37-40 parts of tetrabutyl titanate and an appropriate amount of absolute ethyl alcohol. The capacity for passivating metal of the paint is improved, a high-compactness oxidation film is generated on the surface of low-alloy steel, and the metal represents higher corrosion resistance.
