Problems solved by technology

[0003] At present, domestic wind turbine blades generally use imported polyurethane coatings, epoxy resin coatings, or imported gel coats to protect FRP blades. However, due to the location of wind farms, most of them are distributed in desert areas with strong wind and sand. The existing gel coats or coatings are resistant to wind and sand. The performance is not good, and it cannot solve the problem of the impact and damage of rain, snow, wind and sand, hail and wind and sand on the surface of the blade, which often causes the wear of the blade, thus affecting the service life of the wind turbine

Abstract

The invention discloses a coating for blades of a wind generation set, which is formed by polyurethane NEUKAPOL 1007, polyester ether NEUKADUR 1036, curing agents, auxiliaries, auxiliaries and titanium dioxide powder R930. Double-component polyurethane NEUKAPOL 1007 and double-component polyester ether NEUKADUR 1036 are chosen, the chosen polyurethane and polyester ether are low-viscosity resin with high hydroxyl values (respectively being 550-590 and 160-170), the resin is very small in molecular weight and can form coating films with high cross-linking density, the coating films have extra high surface hardness and excellent elasticity, bending resistance, elasticity and physical and mechanical performance and can avoid stress concentration, and therefore the coating films formed by the coating have good tensile strength, tearing strength and stone striking resistance, and service life of the wind generation set is ensured.

Description

technical field [0001] The invention relates to a coating, in particular to a coating for wind turbine blades, and belongs to the technical field of coatings. Background technique [0002] With the development of society, wind power generation is becoming more and more widespread. Wind turbine blades are one of the core components of wind turbines. At present, the blades are mainly made of FRP composite materials, and the designed service life is usually 20 years. Since wind turbines work in harsh environments for a long time, they have high requirements for corrosion resistance, wear resistance, weather resistance, ultraviolet resistance, and anti-icing performance. Therefore, they must be effectively protected. [0003] At present, domestic wind turbine blades generally use imported polyurethane coatings, epoxy resin coatings, or imported gel coats to protect FRP blades. However, due to the location of wind farms, most of them are distributed in desert areas with strong w...
