The silicone rubber with high strength and high-temperature resistant properties was prepared via a dual-vulcanizer system based on the raw silicone rubber containing of both vinyl group and hydroxyl group. The effect of the dosage of cross-linker KH-CL, the processing way of silicon oxide and the antioxidant on the properties of silicone rubber were investigated. The optimum recipe was confirmed. It’s shown that the optimum dosage of KH-CL is 3phr, which is benefit for the vulcanization and the suppression of the main chain of silicone rubber. The silazane treated silicon oxide and home-made antioxidant are the optimum additives of the silicone rubber. The prepared silicone rubber shows outstanding heat-resistant properties at 350 ℃ for a short time and 300 ℃ for a long time.
