Abstract

The invention discloses an oil-resistant rubber sealing ring material and a preparation method thereof. The rubber sealing ring material is prepared from the following raw materials: chloroprene rubber CR2442, lightweight carbon black AB770, an anti-aging agent MB, dicumyl peroxide, phenyltriethoxysilane, an antioxidant 1035, modified iron ore tailings, propanediol sebacate polyester and perogol. The chloroprene rubber CR2442 as a main material is low in price and good in oil resistance, heat resistance and ozone resistance; the modified iron ore tailings are added into the raw materials, so that the inner bonding force of a rubber sealing ring is enhanced. As a result, the tensile resistance, oil resistance, heat resistance, metal bonding property, mechanical property and the like of the rubber sealing ring are effectively improved.
