摘要

风力发电机叶片在服役过程中经常会受到覆冰影响,超疏水材料由于其特殊的湿润性,在防冰领域具有较大的应用潜力。基于此,以风力发电机叶片为基底,在其表面旋涂由环氧树脂(EP)、聚二甲基硅氧烷(PDMS)和改性的SiO2等配制的无氟悬浮液,固化后制得耐磨防冰的超疏水试样。采用扫描电镜、红外光谱仪和接触角测量仪分别对超疏水涂层的微观形貌、成分组成和疏水性能进行研究。结果表明:超疏水涂层的接触角为166.65°,滚动角为2.5°。相比于无涂层风机叶片,涂层在-10℃和-15℃延长结冰时间40%左右,并且涂层结冰后冰层的粘结强度明显小于风机叶片的。涂层在800目砂纸上磨损10 m后接触角为150.5°。制备的耐磨超疏水涂层具有超疏水效果和良好的防冰性能。

Abstract

Wind turbine blades are often affected by ice coating during service. Due to its special wetness, superhydrophobic materials have great application potential in the field of anti-icing. Based on this, using the wind turbine blades as the base, and a fluorine-free suspension formulated with epoxy resin(EP), polydimethylsiloxane(PDMS) and modified SiO2 was spin-coated on the surface of wind turbine blades, and a wear-resistant and anti-icing superhydrophobic specimen was produced after curing. In addition, the microstructure, composition and hydrophobicity of superhydrophobic coatings were studied by scanning electron microscopy, infrared spectroscopy and contact angle measurement instruments, respectively. Results showed that the contact angle of the superhydrophobic coating was 166.65°, and the rolling angle was 2.5°. Compared to uncoated fan blades, the coating prolonged the icing time by about 40% at-10 ℃ and-15 ℃, and the bonding strength of the ice layer after coating icing was significantly lower than that of fan blades. The contact angle of the coating after 10 meters of wear on the 800 mesh sandpaper was 150.5 °. Overall, the prepared wear-resistant superhydrophobic coating possessed superhydrophobic effect and good anti-icing performance.
