The invention discloses a water-based heavy corrosion protection ceramic paint comprising an A component and a B component, wherein the A component is dispersoid of water-based epoxy resin emulsion, water, a thickening agent, a film-forming auxiliary agent, a flash erosion inhibitor, a foam inhibitor, a foam breaker, a wetting dispersant, a coupling agent, a flatting agent, physique fillers and ceramic powder; the B component comprises the following materials in proportion: 40.0%-70.0% of water-based epoxy hardeners and 30.0%-60.0% of the water; and the water-based heavy corrosion protection ceramic paint can be prepared by mixing the A component with the B component according to the mass ratio of 6.6:1 and stirring. The water-based heavy corrosion protection ceramic paint has the advantages of safety, environmental protection, direct coating, compact coating, strong abrasion performance, low cost, excellent corrosion protection performance, normal temperature solidification, easy spraying, simple process, high insulativity and very strong sterilizing and mildew-proof function and is a water-based environment-friendly heavy corrosion protection ceramic paint especially suitable for the corrosion protection of pipelines.
