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.
Description
technical field [0001] The invention relates to the technical field of rubber for automobile oil cylinder seals, in particular to an oil-resistant rubber. Background technique [0002] With the continuous development of automobile manufacturing technology, people have higher and higher performance requirements for various parts of automobiles, especially the oil resistance performance requirements of rubber used for automobile oil cylinder seals. At present, although there are various types of oil-resistant rubber products, the problem of poor oil resistance is still common. Contents of the invention [0003] The invention provides an oil-resistant rubber, which has good oil resistance and can solve the problem of poor oil resistance existing in existing oil-resistant rubber products. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] It is made of the following components by w...
