Environment-friendly thermal-insulation anticorrosion coating and coating process thereof

The invention provides an environment-friendly thermal-insulation anticorrosion coating and a coating process thereof. The environment-friendly thermal-insulation anticorrosion coating comprises three environment-friendly anticorrosion thermal-insulation layers with different characteristics, wherein a priming layer is a high temperature resistant layer with a thickness of 230 mu m, a medium layer is a thermal-insulation layer with a thickness of 100 mu m and a surface layer is an anticorrosion layer with a thickness of 200 mu m. The three layers are coated through spraying. Complementation and superposition of the three layers enable the thermal-insulation reflective anticorrosion coating to be formed, so the effects of anticorrosion, thermal insulation and energy conservation can be redoubled; and the anticorrosion coating can be extensively used in fields like energy saving buildings, water heating, the chemistry industry, the aerospace industry and shipping.
