Description

technical field [0001] The invention relates to a wall paint, in particular to a weather-resistant exterior wall paint, which belongs to the field of building materials. Background technique [0002] Exterior wall paint is a kind of paint used to paint the facade of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. The exterior wall paint also requires water resistance and self-cleaning properties. The paint film must be hard and smooth, and the dirt will fall off as soon as it is washed. [0003] Existing exterior wall paints are generally formulated with water, pigments, film-forming aids, dispersants, defoamers, thickeners, wetting agents, fillers, antifreezes, etc. Sex is poor. In summer, due to strong ultraviolet radiation, the paint film is very prone to aging, loss of light, fading, discoloration, cracking, and chalking, which seriously affect the decorative effect and use value.
