Abstract

The invention discloses oil resistant rubber, belonging to the technical field of rubber for automobile oil cylinder sealing. The oil resistant rubber is prepared from the following components in parts by weight: 35-46 parts of butadiene-acrylonitrile rubber, 20-30 parts of isoprene-butadiene rubber, 20-26 parts of polyhexamethylene biguanide hydrochloride, 8-12 parts of sulfur, 8-12 parts of fast extruding furnace black, 5-8 parts of dithiodimorpholine, 2-4 parts of zinc stearate, 1-5 parts of isobutyltriethoxysilicon, 5-8 parts of dibutyl phthalate and 1-5 parts of sodium pyrosulfite. The oil resistant rubber is prepared by mainly compounding butadiene-acrylonitrile rubber and isoprene-butadiene rubber and then adopting the following auxiliary components: polyhexamethylene biguanide hydrochloride, sulfur, fast extruding furnace black, dithiodimorpholine, zinc stearate, isobutyltriethoxysilicon, dibutyl phthalate and sodium pyrosulfite, so that the oil resistance of the oil resistant rubber can be effectively improved.
