Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based solar heat reflection and thermal insulation nano coating. Background technique [0002] The growth of all living things depends on the sun, and solar radiation is the main source of energy on the earth's surface. After the surface of an object exposed to sunlight absorbs solar radiation energy, the energy is mainly converted into heat energy, which increases the surface temperature of the object. Buildings, granaries, oil storage tanks, oil tank transport vehicles, temporary workshops, mobile homes, industrial equipment, instruments and equipment, etc. are exposed to sunlight for a long time, so the temperature of their outer surfaces will rise greatly, especially in summer. Due to the increase of the temperature of the outer surface, a large amount of heat will be transmitted into the room through the wall or the wall, which will affect the living co...
