Abstract

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.

Description

technical field

[0001] The invention relates to a self-cleaning super weather-resistant powder coating and a preparation method thereof, belonging to the field of new chemical materials. Background technique

[0002] Powder coating is a new type of powder coating material that does not contain liquid solvents and thinners. It has the advantages of high efficiency, energy saving, and no three-waste pollution. It is being widely used all over the world, and its usage is at an average rate of 10% per year. increase. How to make the surface of weather-resistant architectural coatings self-cleaning through material modification has become a hot topic in domestic and foreign enterprises, universities and research institutes this year. Fluorocarbon coatings are sought after due to their super weather resistance. The foreign fluorine coatings market started in the 1940s, while my country's fluorine coatings market did not start to get on the right track until the end of the 1990s, ...
