Meanwhile, the offshore wind power is impacted by water vapor, salt fog erosion and sea waves for a long time, so that the problem of corrosion is easy to occur. The safe operation of the device and the continuation of the lifetime must be ensured by means of anticorrosive paint. Wind power protective paint mainly comprises tower anti-corrosion paint and blade protective paint, and tower bases, hubs, bearings, nacelle covers, fairings and other electrical equipment also need protection of the paint. The wind turbine blade of the wind driven generator has the problems of pinholes, defects and the like in the production process. Therefore, after the blade is molded, the repair putty is used to repair the surface defects of the blade. The repair putty for the wind power blade is a high-solid-content or solvent-free system, and has the requirements of flexibility, strength, easiness in polishing, sagging prevention, good blade coating property, good interlayer adhesive force between a blade base material and a blade primer, and the like. Most wind power equipment is built in desert or coastal areas to acquire wind power, so that the surfaces of the blades are easily corroded by wind and sand and high-salt seawater, damage is caused on the surfaces of the blades, and the service life of the wind power blades is influenced.
