A Research on the Super-hydrophobic Surface Constructing Method for the Out-door Insulator Based on the Recycling of Composite

摘要

Super-hydrophobic surfaces is a probable method to solve the icing and contamination problems in the out-door insulation. Considering the large amount of the out-door insulation equipment, we are in urgent need of a cheap and convenient constructing method. In this paper, a super-hydrophobic surface constructing method has been studied in which the sheath of the composite insulators has been used as the raw material. With this new method, two problems, the constructing of the super-hydrophobic surfaces and the recycling of the composite insulators which are difficult to degradation and harmful to the environment, have been resolved at the same time. Firstly, the pyrolysis method was used to simulate the combustion process of silicone rubber housing, and FTIR, TGA-MS, XPS and LPSA were used to analyze the formation of solid products and gas products during the pyrolysis of silicone rubber. According to the analysis of the physical and chemical properties of the products, the best experimental parameters have obtained. Secondly, A super-hydrophobic surface has been constructed on the surface of an originally hydrophilic material, glass, which is commonly used in the out-door insulation. Finally, the performance of the super-hydrophobic coating has been analyzed, and its static contact angle and rolling angle have been measured, as well as the anti-contamination flash performance. The experimental results show that the surface constructing method based on the recycling of the composite insulators could get a super-hydrophobic surface which could slow done the icing process, and improve the contamination flashover performance as well.
