Abstract

The invention discloses irradiation-resistant and high-temperature-resistant phenylene silicone rubber and a preparation method thereof. The irradiation-resistant and high-temperature-resistant phenylene silicone rubber comprises the following raw materials in parts by weight: 85-100 parts of composite phenylene silicone rubber, 10-15 parts of an irradiation-resistant auxiliary agent, 10-20 partsof rare earth salt, 3-5 parts of a plasticizer, 3-5 parts of an anti-aging agent and 5-10 parts of a reinforcing agent. The preparation method comprises the following steps: sequentially adding the composite phenylene silicone rubber, the radiation-resistant assistant, the rare earth salt, the plasticizer, the anti-aging agent and the reinforcing agent into a mixing mill, mixing for 30 minutes toobtain a mixture, carrying out heat treatment on the mixture at 190-200 DEG C for 1 hour, cooling, adding into a vulcanizing machine, and vulcanizing at 150 DEG C under the pressure of 25-30 MPa for 10 minutes to obtain the radiation-resistant high-temperature-resistant phenylene silicone rubber. By introducing the molybdenum element into the primary resin, the molybdenum element can form a chemical bond with very high bond energy, so that the high-temperature resistance of the primary resin is improved, and the finally prepared composite phenylene silicone rubber has excellent toughness and high-temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of rubber preparation, and particularly relates to a radiation-resistant and high-temperature-resistant phenylene oxide silicone rubber and a preparation method. Background technique [0002] At present, the commonly used radiation-resistant fillers on the market are divided into inorganic fillers and organic fillers. The inorganic fillers are mainly lead oxide and barium sulfate, and the organic fillers are mainly some small molecular organic compounds containing benzene rings. CN101200569 provides a preparation method of radiation-resistant thermoplastic elastomer. It is composed of thermoplastic elastomer styrene-ethylene-butylene-styrene block copolymer, polystyrene resin, radiation protection agent and antioxidant, and is prepared by melting method. Benzene, biphenyl, diphenylacetylene, diphenylmethane, naphthalene, and anthracene are selected as protective agents, which can transfer the irradiation e...
