Abstract

The invention discloses an automotive oil seal ring, comprising, by weight, 100 to 125 parts of silicone rubber, 100 to 120 parts of butadiene rubber, 80 to 100 parts of nitrile-butadiene rubber, 80 to 100 parts of styrene butadiene rubber, 60 to 80 parts of butyl rubber, 60 to 80 parts of isoprene rubber, 5 to 8 parts of petroleum ether, 8 to 10 parts of diethylene glycol monobutyl ether, 5 to 8 parts of cyclopentadiene, 8 to 10 parts of dioctyl phthalate, 3 to 5 parts of coconut oil, 3 to 5 parts of rapeseed oil, 5 to 8 parts of realgar, 6 to 10 parts of ammonium hydrogen phosphate, 8 to 10 parts of basic cupric carbonate, 10 to 12 parts of silicon carbide powder, 6 to 8 parts of polyvinyl alcohol, 8 to 10 parts of nano-titanium dioxide, 8 to 10 parts of nano calcium carbonate, 8 to 12 parts of calcite powder, 6 to 8 parts of N-phenyl-alpha-benzenamine anti-aging agent, 8 to 10 parts of polypropylene glycol, 6 to 8 parts of diethylene glycol, and 8 to 10 parts of emulsified silicone oil. The automotive oil seal ring is low in cost, stable in performance, high in strength, low in compressive deformation, resistant to high and low temperatures, excellent in performance, and free of breakage and deformation in long-term operation.

Description

technical field [0001] The invention relates to the technical field of an oil seal ring, in particular to an automobile oil seal ring. Background technique [0002] The traditional sealing ring uses ordinary NBR as the main raw material, and its formula design often takes tear resistance, wear resistance and extrusion resistance as key considerations, and its use medium is not fully considered in the formula design process. The self-lubricating performance, heat resistance, aging resistance and other aspects of the sealing ring in the same working condition are far from meeting the requirements of use. Therefore, it is easy to twist and crack due to the increase of torque during assembly, and the service life is short. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an automotive oil seal ring, which has low cost, stable performance, high strength, low compression set, high...
