Problems solved by technology

At present, the quality and price of architectural coatings on the market are uneven, and the sudden change of environmental factors (freeze, sun exposure, rain erosion, etc.) leads to unstable performance. During the application process, there are often peeling off, Cracking and other adverse phenomena occur, the weather resistance is poor, and the service life is short, which seriously affects the appearance of buildings and the value of coating products
[0003] Some existing building interior and exterior wall coating products have good functionality, and have certain effects of thermal insulation, sound insulation, energy saving and noise reduction. However, there are few reports on these coating products having the function of electromagnetic wave absorption, and most of them are electromagnetic wave shielding / anti-interference ; It is undeniable that electromagnetic pollution has become the fifth largest public hazard to human beings after air pollution, water pollution, solid waste, and noise pollution. Its harm to human life and work and electrical equipment is immeasurable. The shielding effect cannot eliminate electromagnetic pollution, and it will still cause harm to social groups; therefore, it is necessary to develop a building wall coating with good electromagnetic absorption

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wall coating composition. Background technique [0002] Coatings are widely used. The traditional name in China is paint. It is mainly a viscous liquid made of polymer resins, emulsions, inorganic fillers, additives, organic solvents or water, with or without pigments; It is used on the exterior wall, interior wall and ground of the building. At present, the quality and price of architectural coatings on the market are uneven, and the sudden change of environmental factors (freeze, sun exposure, rain erosion, etc.) leads to unstable performance. During the application process, there are often peeling off, Unfavorable phenomena such as cracking, poor weather resistance, and short service life seriously affect the appearance of buildings and the value of coating products. [0003] Some existing building interior and exterior wall coating products have good functionality, and h...
