Abstract

The invention relates to an oil resistance rubber, wherein the main components comprise, by mass, 85-95 parts of nitrile butadiene rubber, 1-2 parts of stearic acid, 1-3 parts of an anti-aging agent RD, 1-3 parts of an anti-aging agent 4010NA, 15-30 parts of carbon black N660, and 1-2 parts of poly(hexamethylenebiguanide)hydrochloride. The oil resistance rubber of the present invention has the following advantages that: the poly(hexamethylenebiguanide)hydrochloride is added to the rubber components, the oil resistance of the produced oil resistance rubber is less than 8.5%, the heat resistance and the gas tightness are good, the process is simple, and the production is convenient.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to an oil-resistant rubber. Background technique [0002] Rubber products are a general term for finished products made from rubber as the main raw material through a series of processing. Their common feature is that they have special high elasticity, excellent wear resistance, shock absorption, insulation and sealing properties. Ordinary rubber is not oil resistant. Contents of the invention [0003] The present invention is to provide an oil-resistant rubber. [0004] In order to solve the above technical problems, a kind of oil-resistant rubber of the present invention, its main component is NBR, stearic acid, antioxidant RD, antioxidant 4010NA, carbon black N660, polyhexamethylene biguanide hydrochloride; Score ratio: 85-95 parts of nitrile rubber, 1-2 parts of stearic acid, 1-3 parts of anti-aging agent RD, 1-3 parts of anti-aging agent 4010NA, 15-30 parts of carbon b...
