Abstract
The invention discloses a rubber bushing for an oil pump, which comprises the following components in parts by weight: 50-55 parts of nitrile-butadiene rubber N-41, 25-30 parts of PVC (polyvinyl chloride), 2.2-2.4 parts of stearic acid, 1.4-1.6 parts of promoter DM, 1-1.2 parts of promoter SA, 0.5-0.6 part of crosslinking agent DCP, 30-34 parts of white carbon black, 1.5-1.7 parts of anti-aging agent MB, 4-5 parts of zinc oxide, 16-18 parts of softening agent and 4-5 parts of sulfur. According to the invention, because of favorable oil resistance and moderate processing, the nitrile-butadiene rubber N-41 is used as the main body material of the bushing; the white carbon black is used to improve the oil resistance, wear resistance and tearing strength; the promoter, the sulfur and the like are used to provide heat resistance and aging resistance for the bushing and reduce the permanent deformation of the bushing; the tensile strength is 16-18 MPa; the extension percentage is 500-550%; the Shore A hardness is 68-71 degrees; the tearing strength is 45-50 KN/M; the permanent deformation is no more than 15%; the aging coefficient under the condition of 24h at 90 DEG C is no less than 0.9; and the service life is increased by 2-2.5 times.
