Self-cleaning super-weather-proof powder paint and preparation method thereof

The invention belongs to the field of powder paints and particularly relates to a self-cleaning super-weather-proof powder paint. The self-cleaning super-weather-proof powder paint comprises a carboxyl-terminated polyester particle system and a fluorocarbon resin particle system in a weight part ratio of 4:1-1:4, wherein the fluorocarbon resin particle system contains TiO2 nano-particles. As carboxyl-terminated polyester is introduced into a pure fluorocarbon paint, the phase separation occurs in a solidification process, and the fluorocarbon resin floats up to the surface of a coating to serve as coating protection and ageing resistance; the carboxyl-terminated polyester and the like and a substrate can be well wetted, so that the coating and the substrate can be well adhered and can hardly crack and spall; as the TiO2 nano-particles only exist in a fluorocarbon phase, the resin on a bottom layer cannot be broken, and the excellent stability of the system is guaranteed; and the TiO2 nano-particles are scattered in a dry blending manner, and the complex preprocessing is avoided, so that the preprocessing process can be greatly shortened, the cost is lowered, and the efficiency is improved.
