High-temperature-resistant ethylene propylene rubber sealing pad and preparation method and application thereof

The invention relates to the technical field of ethylene propylene rubber sealing pads, in particular to a high-temperature-resistant ethylene propylene rubber sealing pad and a preparation method and application thereof. The high-temperature-resistant ethylene propylene rubber sealing pad is made from ethylene propylene copolymer, furnace carbon black, spray carbon black, zinc oxide, aluminum oxide, a vulcanizing agent, an assistant cross-linker, an anti-aging agent and the like, wherein fully saturated ethylene propylene copolymer is used as a rubber raw material, and the prepared high-temperature-resistant ethylene propylene rubber sealing pad has excellent weatherability, dielectric resistance and temperature tolerance, may be used for a long time at 150 DEG C and may be used temporarily or intermittently at 180 DEG C, fatigue resistance and high-temperature aging resistance of the traditional ethylene propylene rubber sealing pad are improved, and the problems of the prior art that high-temperature fatig
