Abstract:
The properties of coatings and the polyurethane film that are both applied on the leading edge of wind turbine blades have been discussed. Several typical properties(e.g., tensile strength, adhesion, salt fog resistance and UV resistance) and the rain resistance are examined. Meanwhile, the effects of environment on the rain resistance of the coatings are investigated. The rain resistance of the coatings after UV resistance test is examined in particular. The results show that the performance of the rain resistant coatings applied initially and for a certain period can reach or even surpass the property of the polyurethane film. Therefore, the rain resistant coatings will play a significant role in the future research of the rain erosion materials for wind turbine blades.
Key words:

摘要：
对风机叶片前缘耐雨蚀涂料及聚氨酯膜性能进行了研究,测试涂膜拉伸性能、附着力、耐盐雾性、耐紫外性等常规性能及耐雨蚀性能,并考虑了环境对叶片前缘耐雨蚀防护材料性能的影响,测试了紫外老化后雨蚀性能。结果表明:耐雨蚀涂料性能在使用初期阶段及一定使用时间后,性能均能达到或超过聚氨酯膜的性能,是未来风机叶片耐雨蚀材料的重要发展方向。
