Abstract: ［Objective］By adding modified inorganic fillers，the abrasion resistance of the coating is improved，providing effective solutions for long-lasting anti-icing.［Methods］ A highly durable hydrophobic coating with delayed icing effect was prepared，with fluorocarbon resin as the film-formingmaterial and quartz powder and silica combined with low surface energy long-chain organosilicon asthe functional fillers. The study focused on the coating′s hydrophobicity，resistance to mechanical damage，artificial weathering test and anti-icing performance.［Results］The results showed that the developed coating had water contact angle of 120°，classifying it as a non-wetting hydrophobic material. The pull-off adhesion reached 7 MPa，and after abraded 3 000 r by abrasive wheels，the mass loss was less than 0. 05 g. After 3 000 h of artificial weathering test the gloss retention exceeded 80%.Additionally，water droplets at low-temperature environments revealed a significant delay in iceformation and reducing ice adhesion on the coating.［Conclusion］Homemade organic silicon anti-icing coatings have anti-icing performance and high abrasion resistance，and are expected to provide an important solution to icing problems in wind power facilities，railway transportation，and power transmission in low-temperature environments.
