摘要

为提高硅橡胶复合绝缘子抗污闪及冰闪能力，采用激光雕刻机在其伞裙试样表面加工一系列不同类型的织构，使其具有超疏水性。采用三维形貌仪、SEM观察织构表面形貌特征，采用接触角测量仪、高速摄像机等进行疏水性能分析。分析了织构参数对硅橡胶表面疏水性能的影响，得到各织构疏水性能最佳时的尺寸参数及水滴弹跳性能。结果表明：设计的表面织构可明显改善硅橡胶表面疏水性能；不同织构疏水性最佳时织构高度基本相同，但织构宽度和间距参数不同。凸起织构相较于凹坑织构表现出了更好的疏水性能，其中菱柱织构表面具有最优的超疏水综合特性，能够有效的减少水滴在表面的停留，减少覆冰。

Abstract

To improve the resistance of silicone rubber composite insulator to pollution flashover and ice flashover, a series of different textures with different parameters were processed on the surfaces of umbrella skirt samples via laser engraving to make them being superhydrophobic. The morphological characteristics of the textured sample surfaces were observed by three-dimensional profilometer and SEM. The hydrophobicity was analyzed by the contact angle measuring instrument and the high-speed camera system. The effect of different texture parameters on the hydrophobicity of silicone rubber was analyzed and the optimal dimensional parameters and the droplet bounce performance were obtained when the textured surfaces had the best hydrophobicity. Results show that the designed textures can obviously improve the hydrophobicity of the silicone rubber surface. The height of different textures is basically the same in the best superhydrophobic state, however, other size parameters of the textures are different. The convex textures show better super-hydrophobicity than that of the concave textures. The diamond column textured surface has the best superhydrophobic comprehensive characteristics, which can effectively reduce the staying time of the water droplets on the surface and reduce icing.
