Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a building exterior wall coating.
Background
The coating is a liquid or solid material which can form a film under certain conditions to protect, decorate or perform other special functions (insulation, rust prevention, mildew prevention, heat resistance and the like) when being coated on the surface of an object. With the improvement of living standard of people, the pursuit of people for quality of life is also gradually increased, and the building developers also increasingly pay attention to the quality of the building and have higher requirements for building exterior wall decorating materials.
The existing exterior wall coating has some problems, for example, the exterior wall material has poor waterproof performance, and after the exterior wall coating is coated on the exterior wall of a building, the exterior coating can fall off and crack after being blown by wind and rain for a long time, which seriously affects the appearance and waterproof function of the building. And when the temperature is too high in summer, the cracking of the exterior wall coating can be caused by the insolation of sunlight.
