Problems solved by technology

[0004] At present, most wind turbine blades use epoxy FRP or unsaturated polyester FRP as the main film-forming material. These organic FRPs have the advantages of light weight, good mechanical properties, and low cost, but there are still some shortcomings: such as poor weather resistance and wear resistance. poor sex, etc.

Abstract

The invention discloses a wear-resistant anticorrosive paint for air motor blades, which is composed of the following raw materials in percentage by weight: 20-30% of alkyd resin, 5-15% of zinc manganese zirconium titanium alloy powder, 1-2% of glycerol monostearate, 0.5-0.8% of phenyl glycol ether, 0.2-0.5% of sodium hypophosphite, 0.1-0.2% of marine algae extract, 0.1-0.5% of thickener, 0.1-0.5% of leveling agent, 0.1-0.5% of stabilizer and the balance of water. The paint for air motor blades has the advantages of stone impact resistance, wear resistance, impact resistance, excellent weather resistance and high adhesive force, and thus, prolongs the service life of the air motor set.

Description

technical field [0001] The invention relates to a paint, in particular to a wear-resistant and corrosion-resistant paint for wind turbine blades. Background technique [0002] Wind turbine blades are one of the key core components of wind turbines. Their good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. 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. my country's wind resources are mainly distributed in the rich belts of the Three Norths (Northeast, Northwest, and North China), as well as the sea area. The environment in these areas is harsh, the climate is complex, and the damage to the blade substrate itself is serious. Blades...
