Abstract

The invention discloses a special rubber alloy elastomer for sealing members and a preparation method thereof. The special rubber alloy elastomer comprises the following raw materials in parts by weight: 40 to 60 parts of raw rubber of fluororubber, 5 to 20 parts of raw rubber of hydrogenated butadiene-acrylonitrile rubber, 5.01 to 50 parts of filling reinforcing agent, 0.3 to 2 parts of polyperfluoro isopropyl ether oil, 1 to 3 parts of zinc oxide, 0.6 to 1.4 parts of organic peroxides, 0.5 to 2.5 parts of triallyl isocyanurate, and 0.5 to 1 part of lubricant. During the preparation process, technologies of synthetic rubber preparation, moulding and vulcanization of rubber, post treatment, and examination are adopted, and the obtained special rubber alloy elastomer for sealing members has an excellent performance on resisting high temperature, low temperature, low pressure change, fuel oil, engine oil, acids, alkalines, and mixed oil gas, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a special rubber alloy elastic body for a seal and a preparation method thereof. Background technique [0002] The engine is the core component of the "heart" of the car, and its performance directly affects the performance, life and personal safety of the car. The sealing of the engine system is the prerequisite to ensure the normal operation of the engine, so the sealing technology of the engine system is particularly important. In order to solve its sealing problem, it is necessary to install a rubber seal between the engine block and its fittings. After the rubber seal is compressed, it will generate a rebound force, and a certain sealing contact pressure will be generated in the required sealing area, thereby preventing the cylinder The liquid or gas inside the body can not leak out, and it also reduces the vibration of the cylinder body and the noise between the m...
