Abstract

The invention discloses a biological fuel oil-resistant rubber sealing element material, which is prepared from the following raw materials in parts by weight: 100 parts of a mixture of nitrile rubber and polyvinyl chloride, 50-70 parts of fast extruded carbon black, 3-8 parts of an indirect zinc oxide, 1-2 parts of stearic acid, 1-3 parts of 2,2,4-trimethyl-1,2-dihydroquinoline polymer, 1-3 parts of 4,4-bis(a,a-dimethyl benzyl)-diphenylamine, 5-10 parts of a polyester plasticizer, 3-8 parts of calcium hydroxide, 3-5 parts of ultra high molecular weight polyethylene, 1-3 parts of paraffin, 1-2 parts of sulphur, 0.5-1.5 parts of an accelerant TMTD and 1-3 parts of an accelerant CBS. The invention further discloses a preparation method of the biological fuel oil-resistant rubber sealing element material. The biological fuel oil-resistant rubber sealing element material is capable of effectively resisting expanding corrosion of biological fuel oil and preventing extracting corrosion of biological fuel oil, and has good biological fuel oil resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a biofuel-resistant rubber seal material and a preparation method thereof. Background technique [0002] Our current vehicle fuels are mainly gasoline and diesel, which are synthesized from petrochemicals. However, the regeneration time of petroleum is too long, and it takes tens of thousands of years to complete, so the fuel synthesized from petroleum is basically non-renewable fuel. At the same time, biofuel is a kind of energy produced based on vegetable oil. It is a renewable fuel. Biofuel is not limited by oil reserves. After the efforts of agriculture and biologists, its consumption will not be exhausted. At the same time, bio-fuel has no harmful elements such as sulfur and benzene in petroleum, and has less pollution to the atmosphere after combustion, so it is also called clean fuel. [0003] Biofuels are now partially replacing traditional gasoline and diesel. However,...
