Abstract

The invention discloses an oil-resistant silicon rubber composition. The oil-resistant silicon rubber composition comprises silicon rubber, white carbon black, quartz powder, acetylene carbon black, kieselguhr, polytetrafluoroethylene, zirconia, platinum complex, structure inhibitor, liquid silicon rubber, vulcanizing agent, vinyl-containing silane coupling agent, methyl silicone oil, barium metasilicate, titanium oxide and zinc stearate. The composition overcomes the defect of poor high-temperature resistance in the existing oil-resistant rubber material, and has the advantages of low cost and favorable oil-resistant effect.

Description

technical field [0001] The invention relates to the technical field of silicone rubber, in particular to an oil-resistant silicone rubber composition. Background technique [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 pro...
