Problems solved by technology

[0003] Some coatings with self-cleaning function have been developed on the market. However, the self-cleaning method cannot satisfy the long-term effect. After a long period of wind and rain, the surface of the coating is seriously polluted by dust, which leads to a decline in the effect of radiation cooling

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to radiation refrigeration self-cleaning coatings. Background technique [0002] The main function of exterior wall paint is to decorate and protect the wall of the building, so that the appearance of the building is clean and beautiful, so as to achieve the purpose of beautifying the urban environment, and at the same time, it can protect the exterior wall of the building and prolong its service life. However, due to the long-term exposure of exterior wall coatings to the atmospheric environment and the influence of dust, rain and snow, and sunlight in the atmosphere, the exterior wall coatings have high performance requirements during use, such as self-cleaning performance, refrigeration performance, etc. [0003] Some coatings with self-cleaning function have been developed on the market, but the self-cleaning method cannot meet the long-term effect. At the same time, in ter...
