The invention provides a super-hydrophobic insulating coating and a preparation method and application thereof.The super-hydrophobic insulating coating comprises a component A and a component B. The component A is prepared from, by weight, 40-70 parts of film-forming resin, 1-10 parts of modified resin, 5-15 parts of silicon dioxide, 1-5 parts of auxiliaries and 10-30 parts of organic solvent, and the component B is an isocyanate curing agent. Wherein the film-forming resin is fluorocarbon resin, and the modified resin is heptadecafluorodecyl trimethoxy silane resin. The super-hydrophobic insulating coating prepared by the invention has excellent electrical performance, ultraviolet aging resistance and super-hydrophobic capacity, and can prevent arc flashover caused by deposition and attachment of dirt on the surface of a contact network supporting device integrally formed by a novel composite material when being applied to the railway contact network supporting device.
本发明提供一种超疏水绝缘涂料及其制备方法与应用,包括A组分和B组分,A组分由以下重量份的原料制备而成:成膜树脂40~70重量份,改性树脂1~10重量份,二氧化硅5~15重量份,助剂1~5重量份,有机溶剂10~30重量份,B组分为异氰酸酯固化剂,其中所述成膜树脂为氟碳树脂,改性树脂为十七氟癸基三甲氧基硅烷树脂。本发明制备的超疏水绝缘涂料本具有优异的电气性能、耐紫外老化性能和超疏水能力,应用于铁路接触网支撑装置时,可防止污秽物在新型复合材料一体成型的接触网支撑装置表面沉积附着引起的电弧闪络。
