Description

technical field [0001] The invention relates to a coating and a production method thereof, in particular to an exterior wall coating and a production method thereof. Background technique [0002] Facing the increasingly severe energy crisis, the whole world is vigorously advocating energy conservation and emission reduction. According to statistics, building energy consumption accounts for 30-40% of human energy consumption. Therefore, improving the thermal insulation performance of buildings is of great significance for saving energy. [0003] Practice has proved that the use of special energy-saving coatings on the exterior walls of buildings can effectively reduce the heat transfer coefficient of the exterior walls, thereby reducing energy consumption. [0004] As disclosed in Chinese Patent Application Publication No. 101870842, a water-based cold pigment double-coated multi-functional heat-insulating exterior wall paint and its preparation method, the paint includes si...
