Abstract
The invention discloses an oil-resistant rubber sealing material. The oil-resistant rubber sealing material comprises the following components in parts by weight: 100 parts of nitrile rubber, 20-30 parts of natural powder, 3-4 parts of methyl hydrogen silicone fluid, 3-7 parts of zinc oxide, 1-3 parts of stearic acid, 5-10 parts of carbon black, 0.2-0.5 parts of an antiager and 1-1.5 parts of an accelerant. Compared with the existing nitrile rubber, the sealing material disclosed by the invention is capable of providing a more excellent oil-resistant performance.
Description
Technical field
The present invention relates to a kind of oil resisting rubber sealing material.
Background technology
In fuel oil, hydraulic oil seal system, need the paracril of a large amount of use relative moderate, but a certain distance in addition compared by the oil resistance of existing paracril and viton with trifluoropropyl siloxane, be difficult to meet the more harsh requirement of working conditions.
