摘要

为有效降低输电线路绝缘子表面积污引起的污闪事故的发生，通过将改性纳米TiO2、PTFE 与氟碳树脂FEVE 结合，采用压缩空气喷涂技术制备出一种新型氟碳涂层材料，探讨了改性TiO2粒子的最佳添加量。采用扫描电镜(SEM)、原子力显微镜(AFM)研究了涂层的微观形貌，采用接触角测量仪对其疏水性、自清洁性及抗紫外老化性进行了分析。结果表明:改性纳米TiO2的最佳添加量为4%，涂层的附着力可达0 级，静态水接触角最大为121°；TiO2经改性后制备的防污闪复合涂层表面存在大量微纳尺度的柱状锥尖结构，粗糙度更高，其疏水性更好，自清洁性、抗紫外老化性更佳，具备优良的防污闪性能。

Abstract

In order to effectively reduce the occurrence of pollution flashover accidents caused by surface contamination of transmission line insulators， a new fluorocarbon coating material was prepared by combining modified nano-TiO2， PTFE and fluorocarbon resin FEVE using compressed air spraying technology.The optimum addition amount of modified TiO2 particles was discussed.The microstructure was studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM).The hydrophobicity， self-cleaning properties and anti-ultraviolet aging resistance were analyzed using a contact angle measurement instrument.The results showed that the optimum addition amount of modified nano-TiO2 was 4%，the adhesion of the coating reached grade 0，and the maximum static contact angle was 121°.The surface of the anti-pollution flashover composite coating prepared with modified TiO2 exhibited numerous micro-nano scale columnar cone tip structures， resulting in higher roughness.Its hydrophobicity， self-cleaning ability， and anti-ultraviolet aging resistance were improved， demonstrating excellent antipollution flashover performance.
