The invention discloses a waterborne epoxy resin coating for ships. The waterborne epoxy resin coating comprises a component A and a component B, wherein the weight ratio of the component A to the component B is (95-110) to (0.5-1.8). The component A comprises the raw materials in parts by weight: 20-30 parts of epoxy resin E-44, 15-25 parts of siloxane modified epoxy resin, 5-15 parts of novolac epoxy resin, 1-5 parts of allyl glycidyl ether, 5-10 parts of aluminum silicate, 3-8 parts of polypyrrole hollow balls, 3-6 parts of a quartz powder, 2-6 parts of titanium dioxide microspheres, 2-6 parts of kaolin, 2-5 parts of lithium-based bentonite, 0.5-1.5 parts of zinc oxide, 2-5 parts of barium metaborate, 1-2 parts of micaceous iron oxide, 5-15 parts of poly(vinyl alcohol), 1-2 parts of polytetrafluoroethylene, 1-2 parts of emulsified silicone oil, 1-2 parts of a wetting agent, 1-2 parts of castor oil, and 15-30 parts of deionized water. The component B comprises the raw materials in parts by weight: 20-40 parts of cyclohexane tricarboxylic acid anhydride, 5-15 parts of m-xylylenediamine, 2-8 parts of propylene glycol methyl ether acetate, 2-8 parts of texanol ester alcohol, and 15-25 parts of deionized water.
