The invention relates to the technical field of heat-insulating and heat-preserving anticorrosive coatings, in particular to a water-based heat-insulating and heat-preserving anticorrosive matched coating for a storage tank, which comprises a water-based epoxy anticorrosive primer, a water-based heat-insulating and heat-preserving intermediate paint and a water-based acrylic finishing paint. According to the water-based heat insulation and preservation anti-corrosion matched coating for the storage tank, a protection system of the water-based epoxy anti-corrosion primer, the water-based heat insulation and preservation intermediate paint and the water-based acrylic acid finish paint is adopted. The waterborne epoxy anti-corrosion primer can improve the adhesive force between a coating system and a base material and improve the anti-corrosion performance; the water-based heat insulation intermediate paint is low in heat conductivity coefficient and obstructs heat conduction of the storage tank; the water-based
