Background
The paint coating meets the requirements of health and environmental protection, but the paint coating has the trouble of strong water absorption, and can absorb water and change color when being used as a decorative protective coating of a building. If the base material is made of cement, the entered water can bring the saline alkali to the wall surface when being dried, and the saline alkali is accumulated on the surface of the paint film, thereby not only reducing the service life of the cement and accelerating the corrosion, deformation and aging of the cement, but also leading the paint film to discolor and damage. In some building coatings with very low PVC formulations, the paint film is relatively dense, although the moisture entry is limited, some slowly entering moisture penetrates out of the paint film in the migration process and is unbalanced, and the paint film surface or the paint film and the substrate are easy to generate foaming phenomena, so that the paint film is damaged or falls off. Another undesirable consequence of the water absorption of the paint film is that the extensive contact between the water and the surface of the paint film can carry contaminants into the pores of the coating or adhere to the surface of the paint film to form unsightly stains.
