Abstract

The present disclosure provides a high temperature-resistant silicone rubber. The silicone rubber comprises methyl vinyl silicone rubber, white carbon black, hydroxy silicone oil, hydrogen-containingsilicone oil, a heatproof additive and 2,5-dimethyl-2,5-di-(tert-butylperoxy)hexane. The heatproof additive added to the high temperature-resistant silicone rubber can significantly improve the residual quality of the silicone rubber at a high temperature, overcomes the disadvantage of poor compatibility between a commonly used heatproof additive and the silicone rubber, and maintains the originalmechanical properties of the silicone rubber.

Description

technical field

[0001] The disclosure belongs to the field of silicone rubber, and in particular relates to a high-temperature-resistant silicone rubber and a preparation method thereof. Background technique

[0002] Silicone rubber is a special rubber with Si atoms and O atoms alternately bonded to form the molecular main chain skeleton, and various organic groups as side groups. Because of its carbon chain structure different from ordinary rubber, silicone rubber has excellent high and low temperature resistance, weather resistance, electrical insulation, anti-mold and physiological inertia. Ordinary silicone rubber can generally be used for a long time and maintain elasticity in the temperature range of -50-260°C, while the heat-resistant temperature of phenyl silicone rubber can reach 300-350°C. However, with the development of science and technology, especially in the field of aerospace, the current heat resistance of silicone rubber can no longer meet the requirements...
