Abstract

The invention provides a rubber sealing material for a bearing and resisting a mixed fuel system, and belongs to the technical field of rubber sealing materials. The rubber sealing material for bearing and resisting the mixed fuel resistant system is prepared from NBR rubber, PVC resin, a vulcanizing agent, a vulcanizing auxiliary agent, an activator, a protective agent, a reinforcing agent, a softener, a filler and other auxiliary agents. The vulcanizing agent is at least one of sulfur and 1,3-bis(tert-butylperoxydiisopropyl)benzene. The vulcanizing auxiliary agent is at least one of tetramethylthiuram disulfide, N-cyclohexyl-2-benzothiazole sulfenamide, dibenzothiazole disulfide and N-tert-butyl-2-benzothiazole sulfenamide. The activating agent is at least one of zinc oxide and stearic acid. The protective agent is at least one of N-phenyl-alpha-naphthylamine, N-isopropyl-N'-phenyl-p-phenylenediamine and 4,4'-bis(alpha,alpha-dimethyl benzyl)diphenylamine. According to the technical scheme, the oil resistance is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber sealing materials, and in particular relates to a rubber sealing material for bearing mixed fuel systems and a preparation process thereof. Background technique [0002] With the development of the automobile industry in the direction of high performance, low fuel consumption, low emission, low noise and long service life, automobile fuel oil, lubricating oil, refrigerant, etc. are also continuously improved. In recent years, due to the increasing shortage of petroleum resources and people's higher requirements for automobile exhaust emission standards, automobile fuels have been diversified. In addition to traditional automobile fuels (gasoline and diesel), there have also been gaseous fuels ( Natural gas, petroleum liquefied gas, hydrogen, etc.), oxygenated fuels (methanol, dimethyl ether, etc.), biodiesel and mixed fuels (alcohol-containing gasoline, emulsified diesel, etc.) and other new altern...
