Abstract

The invention relates to an anti-icing wind power blade and a preparation method thereof, wherein the outer surface of the wind power blade is coated with a coating material, and the coating materialcomprises, by weight, 20-30 parts of a resin, 1-2 parts of a dispersant, 10-14 parts of a pigment, 0.01-3 parts of an electric conduction material, 0.2-0.4 part of a defoamer, 0.1-0.2 part of a leveling agent, 1-3 parts of a rheological aid, 3-5 parts of a matting agent, 2-4 parts of an adhesion promoter, 0.01-0.5 part of an initiator, 3-10 parts of butyl acetate, 5-8 parts of propylene glycol methyl ether acetate, 6-10 parts of light calcium carbonate, 0.5-0.9 part of anti-settling fumed silica, and 0.2-0.3 part of xylene. According to the present invention, after the blade is coated with thecoating material, the weather resistance, the hydrophobicity, the impact resistance and the wear resistance of the blade are improved so as to save the maintenance cost and prolong the service life.

Description

technical field [0001] The invention belongs to the field of wind power blade equipment, and in particular relates to an anti-icing wind power blade and a preparation method thereof. Background technique [0002] Most of the fan blades are made of epoxy fiberglass, and there are also unsaturated polyester resin composite materials, which have the advantages of light weight, good mechanical properties, and low cost, but there are still some shortcomings: such as poor weather resistance, poor wear resistance, etc. . Wind turbines are mostly located in deserts, mountains, coasts and seas far away from human habitation. The environment is harsh, and the blades need to withstand the erosion of various natural factors such as strong wind, sand, rain, frost, ultraviolet radiation, as well as the abrasion of high-speed operation. Coating protection technology has a wide range of applications in the field of surface protection due to its advantages of simple construction, wide adapt...
