Study on the Anti-Icing Property of a New Type Wear-Resistant Superhydrophobic Coating on Fan Blades
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 hy-drophobicity 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.
