摘　　要：制备超疏水表面是一种新型的抗冰方法。为提高硅橡胶复合绝缘子表面的抗冰性能,采用D80M多功能激光雕刻机进行加工,得到不同类型、不同尺寸参数的复合织构绝缘子伞裙表面。通过测试不同织构表面绝缘子的接触角,得到疏水性能最佳的表面织构类型及尺寸参数。同时,以延缓水滴在试样表面发生结冰的时间为评价标准,利用可程式恒温恒湿试验机设定环境温度为-10℃,测试水滴在不同织构化试样表面的凝结时间。结果表明:表面织构化明显提升了复合绝缘子伞裙表面的疏水性,使其达到超疏水性;尺寸和间距均为350μm的正方形+圆形织构的疏水性和抗覆冰性能最优,且抗冰耐久性良好。Objective Silicon rubber composite insulators have been widely used in high-voltage transmission,distribution lines,and some high-voltage transmission parts machinery due to their good electrical insulation,excellent antipollution characteristics,and low maintenance cost.Transmission lines often work in cold and heavily polluted conditions,and the anti-icing ability of insulators affects the safety of transmission lines.As a new anti-icing method,the superhydrophobic surface has the advantages of low energy consumption,light weight,and simple structure.It also shows a good application prospect in reducing ice-covered flashover,fouling flashover,and tower collapse accidents of high-voltage transmission lines.Many domestic and foreign researchers determined that the superhydrophobic surface has a great positive effect in reducing the adhesion strength of ice on the material surface and has a certain effect of delaying icing.The most widely used method for preparing superhydrophobic silicone rubber surfaces is the coating method due to the physical and chemical properties of silicone rubber.However,the coating in harsh environments can easily fail because of the poor mechanical stability and impact resistance of the coating.In previous studies,superhydrophobic surfaces were obtained using chemical reagents to reduce surface energy after laser processing of micro-nano structures.Herein,the silicone rubber composite insulators umbrella skirt material has the characteristics of low surface energy;thus,it requires no modification through chemical reagents.The laser engraving machine is used to process micron-scale texture to obtain a superhydrophobic surface,which has a higher processing efficiency than a nanoscale machine.Therefore,using a laser engraving machine to prepare a superhydrophobic surface to shorten the icing of the silicone rubber composite insulator has a certain application prospect.Methods Herein,the D80M multifunctional laser engraving machine is used to process different types and dimensional paramete
