The coating comprises the following components in percentage by weight: 0.5-1.5% of 10% sodium hexametaphosphate solution serving as a wetting dispersant, 1.5-2.5% of ethylene glycol serving as an anti-freezing agent, 0.15-0.25% of antifoaming agent, 0.5-1.5% of film forming aid, 0.5-1% of thickening agent, 1.5-2% of bentonite serving as an anti-settling agent, 15-20% of heavy calcium carbonate serving as filler, 0.2-0.5% of monocrystalline silicon powder serving as a reflection functional material, 2-5% of aluminum silicate serving as a reflection thermal insulation functional material, 0.5-1.5% of antimony oxide serving as an infrared absorption material, 8-12% of pigment filler, 8-12% of heat insulation functional material, 25-35% of elastic acrylic emulsion, 20-25% of water serving as a solvent and 0.05-0.15% of ammonia water serving as a pH regulator.

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...
