▎ 摘　　要

NOVELTY - Anti-icing super-smooth polyurea coating comprises component-A and component-B in a ratio of 1:1.5-2.1, where the component-A includes 30-55 pts. wt. modified isocyanate, 20-40 pts. wt. polyether polyol, 10-20 pts. wt. lubricant and 2-10 pts. wt. modified graphene oxide slurry. The component-B is composed of 10-28 pts. wt. chain extender, 40-55 pts. wt. modified amino-terminated polyether, 5-10 pts. wt. diluent, 1-5 pts. wt. foaming agent, 5-10 pts. wt. modified nano molybdenum disulfide and 1-5 pts. wt. auxiliary agent. USE - The anti-icing super-smooth polyurea coating is useful for wind power blades. ADVANTAGE - The coating has low surface energy, exhibits excellent hydrophobicity, and can form a super-smooth polyurea coating with high adhesion performance and anti-icing on the surface of wind power blades, can improve the shelf life of the coating, delays the crystallization process of droplets and reduce the adhesion of ice to the substrate after crystallization, so as to improve the power generation efficiency and shelf life of the fan.
