Zusammenfassung:	The invention discloses oil-resistant rubber which is made of raw material rubber according to a conventional vulcanized rubber production method. The oil-resistant rubber is characterized in that the raw material rubber is prepared from, by weight, 85 parts of NBR40 nitrile rubber, 15 parts of MPOL200 butadiene rubber, 8 parts of zinc oxide, 1.5 parts of stearic acid, 0.5 part of sulfur, 2.0 parts of CZ accelerant, 1.0 part of TMTD accelerant, 50 parts of channel black, 5 parts of DBT dibutyl phthalate and 15 parts of vinyl chloride-vinyl acetate copolymer. According to the oil-resistant rubber, the tensile strength and tear strength of vulcanized rubber are high, the elongation is large, the physical and mechanical properties are stable, the using reliability of a rubber core of a blowout preventer is guaranteed, and the service life is prolonged.
