Abstract

A silicone rubber with UV aging resistance and low water absorption and its preparation method and application are provided. The preparation method uses a coupling agent KH570 and glyceryl monostearate to perform modified treatment on titanium dioxide to obtain modified titanium dioxide, uses a surface-modified coupling agent A171 and glyceryl monostearate to perform modified treatment on fumed silica to obtain modified fumed silica, and further performs subsequent treatment on methyl vinyl siloxane raw rubber, silicone oil, aluminum hydroxide, the modified fumed silica, the modified titanium dioxide, zinc oxide, α-alumina, a coupling agent KH560, a defoamer, iron oxide and a vulcanizing agent to obtain the silicone rubber. The silicone rubber prepared by the preparation method has low water absorption and excellent aging resistance, and its mechanical and electrical properties are also superior.
