风电叶片是风电机组的核心部件之一,主要采用环氧玻璃钢复合材料,要求使用寿命达20年之久,需要进行重点涂装保护。高效的防护效果取决于防护涂层的设计及表面处理、涂装工艺、涂料质量、涂层质量控制。风电机组要求为20年以上的使用寿命,现有兆瓦级风电机组叶片为玻璃纤维增强环氧复合材料,环氧树脂具备优异的粘接性能,同时冲击韧度可达255 kJ/m2,防腐性能优异等,但是目前国内选用的涂装产品涂层薄、附着力低、耐候性能差,不能满足防腐要求。为充分保证
Wind turbine blade is one of the core components of wind turbine, the main use of epoxy glass fiber reinforced plastic composite material, the required life of up to 20 years, the need for key coating protection. Effective protection depends on the protective coating design and surface treatment, coating process, coating quality, coating quality control. Wind turbine requirements of 20 years of service life, the existing megawatt wind turbine blade glass fiber reinforced epoxy composite materials, epoxy resin with excellent adhesion properties, while impact toughness up to 255 kJ / m2, anti-corrosion Excellent performance, etc. But at present, domestic selected coating products coating thin, low adhesion, poor weather resistance, can not meet the anti-corrosion requirements. To be fully guaranteed
