The invention provides high-performance water-based epoxy anticorrosive coating. The coating comprises a component A and a component B. The component A is prepared from the following components in parts by weight: 60-70 parts of waterborne epoxy resin emulsion, 5-8.5 parts of styrene-acrylic emulsion, 2-3.5 parts of a zinc oxide/graphene oxide composite material, 0.5-1.2 parts of cerium-doped nanotitanium dioxide, 1-2 parts of nano attapulgite, 3-5 parts of organic bentonite, 0.2-3 part of pigment, 0.3-0.5 part of a silane coupling agent, 2-3 parts of n-butyl alcohol, 0.3-0.6 part of a dispersing agent, 0.3-0.5 part of a defoamer, 0.2-0.4 part of a leveling agent and 18-25 part of deionized water. The component B is prepared from the following components in parts by weight: 30-35 parts ofpolyether amine, 3-5 parts of diethylenetriamine, 25-32 parts of wet sericite powder and 8-12 parts of talcum powder. The anticorrosive coating is environmentally friendly, all the raw materials arematched with one another, a
