摘要 针对MW级风电叶片用聚氨酯涂料中存在的问题,对比了国内外研究机构的研究进展,提出从不同方面来提升聚氨酯涂料的性能,着重综述了在聚氨酯力学性能、耐候性、环保型以及工艺性能方面取得的研究进展。研究发现:通过对丙烯酸树脂进行聚酯改性,将丙烯酸和聚酯拼用,发挥两种树脂的优点,可有效提升聚氨酯叶片涂料的干燥性、耐候、耐磨、柔韧性、附着力等性能。选择合适的固化剂并在涂层中引入纳米颗粒,增强助剂可以提高涂层的硬度和力学性能。通过设计水性聚氨酯涂料,使涂料具有环保方面的优势,同时可提升其干燥性、耐磨性及耐候性等。叶片涂料工艺采用底面合一可有效提升工艺效率,使得涂膜厚度更加均匀。

Abstract: In view of the existing problems in polyurethane coatings for MW wind power blades, the research progress of domestic and foreign research institutions was compared, and it was proposed to improve the performance of polyurethane coatings from different aspects. The progress in mechanical properties, weather resistance, environmental protection and technological properties of polyurethane was reviewed. It is found that the combination of acrylic acid and polyester can play to the advantages of the two resins by modifying acrylic resin with polyester, which can effectively improve the properties of dryness,weather resistance, wear resistance, flexibility and adhesion. The hardness and mechanical properties of the coating can be improved by selecting suitable curing agent and introducing nano-particles into the coating. Through the design of waterborne polyurethane coating, the coating has advantages in environmental protection, and can improve the dryness, wear resistance and weather resis-tance. The combination of bottom-surface integration process in the blade coating process can effectively improve the process efficiency, and the film thickness is more uniform.
