The invention provides a self-cleaning powder coating based on fluorine-modified acrylate polymer and a preparation method thereof. The raw materials are: 88-92 parts of fluorine-modified acrylate polymer, 0.07-0.12 parts of leveling agent, and 0.9-0.9 parts of dispersant. 1.2 parts, titanium dioxide 6.8-7.2 parts; In the preparation of fluorine-modified acrylate polymer, various monomers, initiators and solvents are formed into a polymerization reaction system, and the introduction of fluorine-containing structural units can reduce the surface energy of the polymer and improve the paint film. The self-cleaning performance of the coating can be further improved by introducing nano-titanium dioxide. Compared with the prior art, the introduction of a fluorine-containing structural unit into the acrylate polymer can improve its water and oil resistance, and at the same time, the introduction of titanium dioxide increases its binding force with the resin matrix and improves the self-cleaning function of the powder coating. |
