Low-compression-change nitrile rubber material and preparation method thereof

The invention discloses a low-pressure-change nitrile rubber material which is prepared from the following raw materials in parts by weight: 100 parts of nitrile rubber, 5-10 parts of zinc oxide, 1-3 parts of stearic acid, 1-2 parts of an anti-aging agent RD, 1-1.5 parts of an anti-aging agent MB, 2-3 parts of an anti-aging agent 4010NA, 2-3 parts of microcrystalline wax 9108, 95-120 parts of carbon black, 20-30 parts of inorganic filler, 20-22 parts of a plasticizer, 2-3 parts of a vulcanizing agent, 1-2 parts of an accelerant, 0.3-1 part of a scorch retarder, 1-3.5 parts of an adhesive RS and 2-4 parts of an adhesive RA-65. Aiming at a sulfur vulcanization system, the adhesive RS and the RA-65 are added, and the adhesive RS and the methylene donor adhesive RA-65 can be subjected to resinification reaction, so that the crosslinking degree of the nitrile rubber material under the low-temperature vulcanization condition is improved, and the low pressure change performance is improved; the nitrile rubber materi
