The invention provides a rubber sealing material for a bearing-resistant mixed fuel system, which belongs to the technical field of rubber sealing materials. A kind of rubber sealing material for bearing and resistant mixed fuel system, which is made of NBR rubber, PVC resin, vulcanizing agent, vulcanizing aid, activator, protective agent, reinforcing agent, softener, filler and other auxiliaries. The agent is at least one of sulfur and 1,3-bis(tert-butylperoxydiisopropyl)benzene, and the vulcanization aid is tetramethylthiuram disulfide, N-cycloethyl-2- At least one of benzothiazole sulfenamide, dibenzothiazole disulfide and N-tert-butyl-2-benzothiazole sulfenamide, and the activator is at least one of zinc oxide and stearic acid, so Described protective agent is at least N-phenyl-α-naphthylamine, N-isopropyl-N'-phenyl-p-phenylenediamine and 4,4'-bis(α,α-dimethylbenzyl) diphenylamine A sort of. The present invention improves its oil resistance through the above technical solutions. |
