▎ 摘  要

NOVELTY - An anticorrosive coating comprises 35-50 pts. wt. epoxy resin E-20, 15-20 pts. wt. butanediol glycidyl ether, 6-12 pts. wt. titanium dioxide, 4-7 pts. wt. silicon powder, 3-6 pts. wt. thinner, 2-5 pts. wt. antiseptic composition, 2-5 pts. wt. butyl acetate, 2-4 pts. wt. curing agent, 1-3 pts. wt. bentonite, 1-3 pts. wt. m-phenylenediamine, 1-2.5 pts. wt. aluminum tripolyphosphate, 1-2 pts. wt. barium sulfate, 0.3-0.8 pt. wt. silane coupling agent, and 0.2-0.5 pt. wt. defoamer. USE - Anticorrosive coating. ADVANTAGE - The coating has good anticorrosion effect and strong adhesive force. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the anticorrosive coating comprising adding polyurethane dispersant to n-butanol, dispersing, adding modified graphene and modified zinc oxide, stirring, adding N-methylpyrrolidone, and stirring to obtain antiseptic composition; mixing butanediol glycidyl ether, titanium dioxide, aluminum tripolyphosphate, barium sulfate, bentonite, silicon powder and curing agent to obtain first mixed liquid; mixing epoxy resin E-20, antiseptic composition, thinner, butyl acetate, m-phenylenediamine and silane coupling agent to obtain second mixed liquid; and mixing first mixed liquid and second mixed liquid, and stirring.
