Abstract

The invention discloses anti-corrosive paint for a low-carbon steel valve. The anti-corrosive paint is prepared from the following raw materials including, by weight, 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 and 0.8-2 parts of dimethicone. The anti-corrosive paint has the advantages that the metal passivation capacity is enhanced, a layer of high-compactness oxidation film is generated on the surface of low alloy steel, the anodic reaction inhibiting capacity is enhanced, a base metal material and a corrosive medium are better isolated from each other, and the corrosion resistance is better.
