Abstract
Abstract When the silicone rubber composite insulator is exposed outdoors for a long time, it will be affected by high‐temperature ultraviolet environments. In order to ensure the operation of silicone rubber composite insulators, a super‐hydrophobic composite insulator with antiaging characteristics was prepared by mixing cerium dioxide (CeO 2 ) with silicone rubber and spraying CeO 2 on the surface of silicone rubber. This article studied the aging characteristics of the base and surface of silicone rubber composite insulator by CeO 2 in ultraviolet environment. The properties of silicone rubber composite insulators before and after aging were tested by mechanics, contact Angle, rolling Angle, bounce, and icing experiments. The aging mechanism of silicone rubber was analyzed by Fourier transform infrared spectroscopy and search engine marketing. This study prepared composite insulators with excellent mechanical, hydrophobic, and antiicing properties. The aging resistance of silicone rubber composite insulators is improved by adding CeO 2 into silicone rubber matrix and spraying CeO 2 on the surface, which also ensure the use of composite insulators in high‐temperature ultraviolet environment.
