Description

technical field [0001] The invention relates to the field of silicone rubber, in particular to a formula of silicone rubber. Background technique [0002] Silicone rubber is an excellent special rubber, which has excellent heat resistance, low temperature resistance, insulation, shock resistance, compression resistance, abrasion resistance and good biological characteristics, making it widely used in construction, transportation, etc. Transportation, electronic appliances, chemicals, biological materials and now aerospace materials, etc. Now silicone rubber can be used for a long time at -65°C to 200°C, but with the development of science and technology, higher requirements are put forward for its heat resistance, and the current aerospace technology requires silicone rubber to be used at higher temperatures for a long time , It is of great significance to further improve the high temperature resistance of silicone rubber. In addition, when the heat resistance is improved, ...
