Problems solved by technology

[0002] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the exterior decoration of buildings is getting more and more attention. Because it is not water-resistant and not waterproof, the paint film will peel off as a whole after being washed by rainwater, which looks unattractive. The requirements for the coating coating on the outer layer of the object are getting higher and higher. The waterproof and anti-seepage problem of the building is related to people's work and living environment, and affects the service life of the building. Therefore, if a waterproof performance is prepared , the coating with long service life has become a technical problem that needs to be solved at present
