Anticorrosive coating for environment-friendly low-carbon steel valve and preparation method of anticorrosive coating

Abstract

The invention discloses an anticorrosive coating for an environment-friendly low-carbon steel valve. The anticorrosive coating is prepared from the following raw materials in parts by weight: 2-3 parts of naphthenic soap, 0.5-1 part of microcrystalline wax, 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 ethylene glycol butyl ether, 80-90 parts of epoxy resin E40, 5-7 parts of polyamide resin, 0.8-2 parts of dimethyl silicone, 0.1-0.2 part of triethanolamine oleic soap, 1-2 parts of dibutyl maleate, 2-3 parts of hydrolytic polymaleic anhydride, 0.1-0.4 part of tetrahydrofurfuryl alcohol, 3-5 parts of magnesium fluoride, 0.1-0.2 part of a silane coupling agent kh560 and a proper amount of absolute ethyl alcohol. According to the anticorrosive coating, the metal passivating capacity is enhanced, and a layer of high-density oxidation film is formed on the surface of low-alloy steel and presents relatively good corrosion resistance.
