Description

technical field [0001] The invention relates to an anti-corrosion coating material and a preparation method thereof, in particular to a high-efficiency energy-saving heat shielding and cooling anti-corrosion coating material and a preparation method thereof. Background technique [0002] The high surface temperature of buildings, industrial equipment, transportation vehicles, etc. caused by solar heat radiation has brought many problems and inconveniences to industrial production and people's daily life. On the other hand, oil storage tanks, thermal equipment, winter buildings, etc. are mostly at a higher temperature than the environment, and heat loss exists in these objects all year round, consuming a lot of energy. Therefore, the research and application of thermal insulation coatings have significant economic and social benefits. Researching an environmentally friendly energy-saving coating with thermal insulation function is the goal that the coatings industry has been...
