DETAILED DESCRIPTION - A low surface treatment grade steel structure graphene anticorrosive coating comprises coating A and coating B. The coating A comprises 10-40 wt.% epoxy resin, 0.5-2 wt.% graphene, 0.2-2 wt.% metal penetrant, 0.1-2 wt.% anti-settling agent, 40-70 wt.% pigment filler and 8-22 wt.% solvent A. The coating B comprises 10-100 wt.% amine curing agent and 0-90 wt.% solvent B. The epoxy resin is modified epoxy resin, modified E20 or modified E44 A. The graphene is sheet structure. The metal penetrant is polyoxyethylene ether. The anti-settling agent is liquid rheology-modified wax, polyamide wax powder or organic bentonite. The pigment filler is titanium pigment, carbon black, precipitated barium sulfate, mica iron oxide ash or phosphate iron powder. The solvent A is cyclohexanone, methyl isobutyl ketone, xylene or n-butanol. The amine curing agent is polyamide, phenolic aldehyde or alicyclic amine curing agent. The solvent B is dimethylbenzene, n-butanol, cyclohexanone or methyl isobutyl ketone.
