Abstract

The invention discloses a method for preparing and spraying an anticorrosion coating for a western wind farm tower. The anticorrosion coating consists of priming paint, intermediate coat and finish, wherein the priming paint comprises an elastic resin A, zinc powder, a mixed solvent, an adhesion promoter, a base material wetting agent, an antifoaming agent and a curing agent A; the intermediate coat comprises an elastic resin B, a shielding impervious material, a mixed solvent, an antifoaming agent and a curing agent B; the finish comprises an elastic resin C, a weather-resistant anticorrosion material, a mixed solvent, an antifoaming agent, a wetting dispersing agent, a flatting agent and a curing agent C. The priming paint can weaken and absorb the impact stress of sand and wind on the film, the intermediate coat can weaken the impact stress from the finish, the elastic deformation capacity of the whole coating is improved, the finish has good weather resistance and has the characteristics of high elasticity, high wear resistance, high breaking elongation, high tensile strength, high sand and wind impact resistance and the like, and according to the preparing and spraying method, main performance indexes of the anticorrosion coating meet the application requirements of the western wind farm tower.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to a method for preparing and spraying anti-corrosion coatings for wind farm towers in western China. Background technique [0002] Most of the wind farms in western China are located in areas with perennial drought and little rain, strong ultraviolet rays, strong and frequent wind and sand, and large temperature differences between day and night. Therefore, the anti-corrosion coating of the towers of the western wind farms is also affected by the above harsh conditions all the year round. The anti-corrosion coating on the near-ground part and the main windward side of the tower will be completely eroded, causing the exposed metal surface of the tower to be corroded, causing the main structure of the tower to be damaged, corroded, and even collapsed, causing serious safety hazards. [0003] According to GB / T 9072-2003 "Wind Turbine Generating Sets-Tower",...
