More Information
Summary:The invention discloses an oil inlet sealing ring material for a vehicle brake master cylinder and a process thereof for manufacturing a sealing ring. The material is prepared from the following components in part by weight: 80 to 120 parts of ethylene propylene rubber, 4 to 6 parts of active agent, 1 to 3 parts of lubricant, 2 to 4 parts of acid-base balance agent, 1 to 3 parts of age resistor, 2 to 4 parts of sulfurizing agent and 25 to 35 parts of inorganic filler; then the components are subjected to the processes, namely mixing and molding, primary sulfurizing, punching and edge removingand secondary sulfurizing to obtain the oil inlet sealing ring material product with high strength, low compression deformation, tear resistance, resistance to braking fluid corrosion, resistance to low and high temperatures and excellent performance for the vehicle brake master cylinder; and the production efficiency and the product percent of pass are high, and the product can completely substitute similar imported prod
