| Abstract: |
| The blades are the key parts of the wind turbine equipment, the well-working of which could not only improve the efficiency of power generation, but also reduce maintenance costs. The blades are always brittle after working for a long time with exposure to the natural environment, especially the leading edge, which is vulnerable to sand and rain erosion. The simplest but most effective method at present is to spray protective coatings on the blades surface. According to the characteristics of the working environment, major features of blades protective coatings were put forward. Several matrix resins applied to the coatings were introduced, including polyurethane, acrylic acid, fluorocarbon, organic silicon and epoxy resins. Research and current applications of the resins in the field of wind turbine protective coatings were described in detail. Polyurethane and acrylic acid resins are most applied with excellent flexibility, abrasion resistance and anti-erosion of sand and rain while fluororesin and organic silicon resins have received more attention owing to the outstanding weatherability and anti-icing properties. Epoxy resins could provide excellent anti-corrosion properties and adhesion between the layers when applied to the primer. Matched coatings systems prepared from modification among these resins have a more excellent effect on protecting the blades on account of different characteristics of different resins, when compared to single resins, which would still be a main research area in future. Finally, the difference in the wind turbine blade coating markets in China and other countries was pointed out, and the development directions of wind turbine blades protective coatings were prospected. |
