Abstract
The invention relates to oil-resistant rubber. The oil-resistant rubber provided by the invention contains natural rubber and has excellent properties of natural rubber. In addition, the oil-resistant rubber is added with chloroprene rubber, so that molecules of the oil-resistant rubber contain chlorine atoms, and the oil-resistant rubber has excellent resistance to oxygen, ozone, oil, solvent, acid, alkali and aging, is nonflammable, can be extinguished naturally after catching fire, and is good in air tightness; nitrile rubber is particularly high in resistance to gasoline and aliphatic hydrocarbon oils, relatively high in heat resistance, air tightness, wear resistance, and water resistance, and strong in binding power. In combination with other auxiliary components, the prepared oil-resistant rubber has good physical and mechanical properties, and high in heat resistance and air tight performance, and the oil resistance is 6% or lower. Therefore, the oil-resistant rubber can sufficiently adapt to the use in automobile cylinder sealing elements.
