▎ 摘  要

NOVELTY - Graphene-containing heavy-duty anti-corrosion coating comprises 1-6 pts. wt. graphene, 10-50 pts. wt. epoxy resin, 0.5-3 pts. wt. hydroxytriazine, 0.5-3 pts. wt. glycidyl ether silane, 10-25 pts. wt. first solvent and 30-65 pts. wt. filler as component A, 38-80 pts. wt. second solvent, 19-60 pts. wt. curing agent, and 0.5-2 pts. wt. aminophenol as component B. USE - The coating is useful for crude oil storage tanks, ships, offshore platforms, and offshore wind power installations, engineering device and facility of seawater, high sulfur-containing crude oil, acid/alkali liquid and other corrosion medium contact. ADVANTAGE - The coating: has excellent comprehensive performance, and no heavy metal containing graphene, has strong hydrogen sulfide corrosion resistance, good acid/alkali resistance, high adhesion, good anti-ultraviolet aging performance, strong salt fog/wet heat characteristics; and can satisfy for preventing corrosion of various metal substrates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the heavy anticorrosive coating containing graphene.
