Production process of diphenyl chain link high-temperature vulcanized phenyl silicone rubber

The invention discloses a production process of diphenyl chain link high-temperature vulcanized phenyl silicone rubber. The preparation method comprises the following steps: adding octamethylcyclotetrasiloxane, a methyl vinyl cyclosiloxane monomer and a methyl phenyl cyclosiloxane monomer into a polymerization reaction kettle; adding an end-capping reagent into the polymerization monomer subjectedto pressure reduction and water removal; carrying out ring-opening copolymerization reaction under the action of a catalyst; after the synthesis reaction is finished, removing the catalyst through heating decomposition or filtration; then removing low-molecular compounds at high temperature under reduced pressure, cooling to room temperature, mixing with a cross-linking agent, methyl phenyl hydrogen-containing silicone oil and a platinum complex catalyst, uniformly mixing, rolling, discharging sheets, continuing primary vulcanization and secondary vulcanization, and molding so as to prepare the diphenyl chain link hi
