Problems solved by technology

[0003] Since latex paint uses water as the dispersion medium, it is easily polluted and destroyed by microorganisms. The product quality of the paint is unstable during the production and storage process, and after the latex paint is dried and formed into a film, it has poor adhesion to the building wall and poor water and weather resistance. , long-term use will cause problems such as cracking, peeling, discoloration, and powder removal. At the same time, the existing latex paint has poor acid and alkali resistance and corrosion resistance, and the paint surface is easily damaged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano ceramic material modified latex paint and a preparation method thereof. Background technique [0002] Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, uses water as the dispersion medium, adds pigments, fillers and additives, and is prepared through a certain process. Latex paint has many advantages different from traditional paints, such as easy to paint, fast drying, water-resistant paint film, good scrub resistance, etc. It is mainly used in interior decoration. [0003] Since latex paint uses water as the dispersion medium, it is easily polluted and destroyed by microorganisms. The product quality of the paint is unstable during production and storage, and after the latex paint is dried and formed into a film, its adhesion to the building wall is poor, and its water resistance and weather resistance are poor. , Long-term use will cau...
