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 outdoor decoration is getting more and more attention. However, 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. At present, acid rain The impact is getting bigger and bigger, which makes the requirements for the paint coating on the outer layer of the building higher and higher. The waterproof and anti-seepage of the building is related to people's working and living environment, and affects the service life of the building. Therefore, if prepare a kind of excellent waterproof performance, anticorrosion performance is good, the coating of long service life becomes the technical problem that needs to be solved at present
