［Objective］Icing seriously threatens the safe operation of equipment such as aircraft， wind turbine blades，and high-speed trains，making it essential to develop protective coating thatexhibit both low ice-adhesion strength with excellent mechanical stability.［Methods］In this study，an epoxy-modified silicone coating system was constructed by incorporating epoxy resin with polyamide， hydroxyl-terminated polydimethylsiloxane，and KH560. In this system，the inherent anti-icing property of silicone materials was preserved，while the mechanical strength of the coating was significantly enhanced.［Results］The prepared epoxy-modified silicone coating exhibited good hydrophobicity andlow surface energy. Even after sand erosion，the coating retained its structural integrity and stable anti-icing performance. Moreover，it demonstrated excellent adhesion on aluminum substrates，reaching a maximum rating of 4B，and formed strong interfacial bonding with an epoxy primer.［Conclusion］The anti-icing properties of silicone and the mechanical advantages of epoxy resin were successfullyintegrated in this work，providing a feasible technical solution for ice protection in extreme coldenvironments such as the underbodies of high-speed trains.
