The invention belongs to the technical field of metal equipment anti-corrosion engineering, and particularly relates to a marine environment water-based graphene composite anti-corrosion coating and a preparation method of the marine environment water-based graphene composite anti-corrosion coating. The graphene modified epoxy resin is prepared from 30-50 parts of epoxy resin, 10-15 parts of modified graphene, 5-8 parts of zinc phosphate, 3-7 parts of talcum powder, 5-10 parts of calcium carbonate, 2-5 parts of a coupling agent, 1-3 parts of an adhesion promoter, 1-2 parts of an anti-settling agent, 1-5 parts of a thickening agent, 7-20 parts of a curing agent and 3-6 parts of other auxiliaries. By modifying the graphene composite material, the dispersity of graphene is remarkably improved, the addition amount of graphene is reduced, the characteristics of good wear resistance, impact resistance and corrosion resistance of lignosulfonate are exerted, and the utilization value of lignin is improved. 本发明属于金属设备防
