Background
At present, the film forming material of the building coating mainly takes organic emulsion as a main component, and has large influence on the environment due to high content of volatile components. And a compact paint film is formed after the organic resin is formed into a film, so that the adsorption function of the functional coating material is seriously hindered, and the air purification performance of the functional coating material is reduced.
The inorganic building coating has nanoparticles with large specific surface area, and is easy to form a network structure which has irreversibility. Therefore, the coating film is hard, strong in adhesion, and excellent in water resistance and chemical resistance. However, inorganic gel materials have large shrinkage during film formation, and the coating film is easy to crack.
