The added high-reflectivity material (Econstan powder) can reflect the visible light and near infrared light (400 nm-2500 nm) in sunlight to the external space, so that most of energy irradiated by the sun on the coating film is reflected instead of being absorbed by the coating film. The heat absorbed by the surface of the object is radiated into the space by using high-heat radiation material (potassium hexatitanate whisker), so that the heat of the sun is not accumulated on the surface of the object to be heated. The density and the heat conductivity coefficient of the coating are reduced by applying a heat insulation material, wherein the heat insulation material comprises a vacuum heat insulation material (hollow glass beads), and the hollow characteristic of the beads enables the beads to have low heat conductivity coefficient, so that heat conduction can be effectively isolated; the porous heat-insulating material (cork powder and aerogel) plays a role in shielding and slowing down the heat transfer and exchange speed, and simultaneously fills gaps in the coating. The preparation process of the product is perfected by the application of the suspending stabilizer and other auxiliary agents. The coating film obtained by scientific and reasonable compounding of the materials has excellent adhesive force to a base material, low density, low thermal conductivity coefficient, difficult cracking at high temperature, excellent heat insulation and cooling functions, and can well play a role in reducing the temperature of a protected object and the heat insulation and cooling of a protected space under the conditions of strong sunlight irradiation and thermal radiation.
