Problems solved by technology

[0002] At present, silicone rubber is widely used in construction, chemical industry, transportation, electronic appliances, biological materials and aerospace materials. It has excellent heat resistance, low temperature resistance, insulation, earthquake resistance, compression resistance, and abrasion resistance. And good biological properties, the current silicone rubber components are generally methyl vinyl raw rubber, white carbon black, hydroxyl silicone oil, hydrogen silicone oil and zinc stearate combination, oil resistance is poor
The commonly used oil-resistant rubber, such as nitrile rubber, hydrogenated nitrile rubber, fluorosilicone rubber, etc., has good oil-resistant effect, but cannot withstand high temperature, so there is a lack of an oil-resistant silicone rubber, which solves the problems of existing oil-resistant rubber materials. Defects that are not resistant to high temperature
