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 bio-fuel-resistant rubber seal material and a preparation method thereof. Background technique [0002] Our current automobile fuels are mainly gasoline and diesel, which are synthesized from petrochemicals. However, the regeneration of petroleum takes too long to be completed in tens of thousands of years. Therefore, petroleum synthetic fuel 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 restricted by oil reserves. Through the efforts of agriculture and biologists, its consumption will not be exhausted. At the same time, biofuel has no harmful elements such as sulfur and benzene in petroleum, and has less pollution to the atmosphere after combustion, and is also called clean fuel. [0003] Now biofuel is partially replacing traditional gasoline and diesel. However, biofuels are m...
