Problems solved by technology

[0003] However, the currently generally used exterior wall paints only serve to decorate and protect the wall from external environmental influences, and do not have the functions of heat insulation and heat preservation, and the weather resistance and waterproof performance of exterior wall paints need to be further improved. improvement, so the current exterior wall paints have certain limitations in use; the existing exterior wall paints are generally composed of water, pigments, film-forming aids, dispersants, defoamers, thickeners, It is formulated with wetting agent, filler, antifreeze, etc., and its stain resistance and friction resistance are poor; in summer, due to strong ultraviolet radiation, the paint film is very easy to age, and loses light, fades, changes color, cracks, Chalking phenomenon seriously affects the decorative effect and use value

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a high-weather-resistance comprehensive exterior wall special paint and a preparation method thereof. Background technique [0002] Exterior wall paint is mainly used in buildings, and it is a kind of paint for painting the facade of buildings. It has two functions: one is to protect the building from the external environment or minimize its impact. After the exterior wall paint is applied to the building, it can form a continuous coating film on its surface. This coating film has corrosion resistance , anti-pollution, anti-ultraviolet radiation, and anti-bacterial erosion, protect the steel bars from corrosion, and protect the concrete from carbonization and chlorination, so as to prolong the life of the building; the second is to decorate and beautify the building, and the exterior wall paint is painted on the surface of the building Finally, ...
