Abstract

[Objective]To address the insufficient durability of superhydrophobic coating for anti-icing in power systems,this study developed a superhydrophobic coating combining wear resistancewith anti-icing performance.[Methods] Using fluoride-modified natural mineral powder(main component:SiO2)as hydrophobic filler compounded with low-surface-energy silicone resin,a wear-resistant superhydrophobic coating was constructed on substrate surfaces via spraying. The influence ofhydrophobic filler content(10% to 35%) on coating performance was systematically investigated.Coating microstructure and wettability were characterized using scanning electron microscopy andcontact angle measurements;anti-icing performance and wear resistance were evaluated via delayed icing tests,ice adhesion strength tests,and sandpaper abrasion tests.[Results]When the hydrophobic filler content was 30%,the coating exhibited a water contact angle greater than 160°,extended the surface ice formation time to 1 420 s(-10 ℃),reduced the ice adhesion strength to below 50 kPa,and maintained a contact angle above 150° even after 200 cycles of sandpaper abrasion. In the applicationvalidation on power transmission cable surfaces,the superhydrophobic coating(SSC-6)prolonged the droplet freezing time from 300 s to 1 200 s.[Conclusion]A wear-resistant superhydrophobic anti-icing coating was successfully developed,offering a potential solution for the anti-icing design of power transmission lines.
