NOVELTY - An aqueous anticorrosive coating comprises component (A) and component (B). The component (A) comprises 10-25 wt.% aqueous epoxy emulsion, 10-15 wt.% silica sol, 1-5 wt.% polyvinyl alcohol binder, 5-10 wt.% aqueous graphene slurry, 0.5-1.5 wt.% aqueous hyperdispersant, 0.5-2.0 wt.% coupling agent, 5-20 wt.% anti-rust functional filler, 0.1-1 wt.% thixotropic agent, 20-40 wt.% metal anti-rust pigment, 0.5-5 wt.% other additive and balance deionized water. The component (B) comprises aqueous epoxy curing agent, an alcohol ether solvent, and deionized water. USE - Aqueous anticorrosive coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of aqueous anticorrosive coating, which involves mixing half of the deionized water, aqueous hyperdispersant, silica sol, aqueous graphene slurry, half of the other additive, and half of the thixotropic agents, dispersing, adding anti-rust functional filler, dispersing to obtain a dispersion slurry (I), grinding the dispersion slurry (I) with a nano-mill, obtaining a grinding slurry, dispersing aqueous epoxy emulsion and balance additive, thixotropic agent and deionized water, adding metal anti-rust pigment and dispersing until the slurry becomes a uniform fluid state, obtaining component (A), dispersing aqueous epoxy curing agent, alcohol ether solvent and deionized water until the slurry becomes a uniform fluid state, and obtaining a compound (B).
