Water-based heat-insulating anticorrosive paint coating structure

The utility model discloses a water-based heat-insulating anticorrosive paint coating structure. Wherein the metal base material is coated with the priming paint layer, the priming paint layer is coated with the heat insulation anti-corrosion layer, the heat insulation anti-corrosion layer is coated with the bonding layer, the bonding layer is coated with the reflective heat insulation surface layer, and the reflective heat insulation layer is coated with the protective layer. The coating structure is provided with the water-based epoxy anticorrosive primer layer and the water-based heat-insulating anticorrosive layer, so that an anticorrosive effect can be achieved on the surface of the metal base material, and corrosion to the metal surface under the action of water, oxygen and the likeis reduced. The aerogel coating is adopted as the bonding layer, the bonding effect is good, the polyurethane transparent protective coating is arranged on the outermost layer, the hardness and the water resistance are good,
