Problems solved by technology

[0002] The traditional sealing ring uses ordinary nitrile rubber (NBR) as the main raw material, and its formula design often takes tear resistance, wear resistance and extrusion resistance as key considerations, which are not fully considered in the formula design process. The sealing rings used in the medium and working conditions are far from meeting the requirements in terms of self-lubricating performance, heat resistance, and aging resistance. Therefore, it is easy to twist and crack due to increased torque during assembly, and the service life is short.

Abstract

The invention relates to a seal ring for an automobile oil seal. The seal ring is prepared from the following components in parts by weight: 25-35 parts of natural rubber, 10-20 parts of ethylene propylene rubber, 4-6 parts of paroline, 3-5 parts of palm oil, 1.5-3 parts of sulfur, 2-4 parts of ceramic micropowder, 4-6 parts of lignin, 3-5 parts of nanosilicon dioxide, 1.5-2.5 parts of an anti-aging agent, 3-5 parts of polyethylene glycol, 2-3 parts of simethicone, 1.5-2 parts of polyurethane, 1-3 parts of Vaseline, 4-6 parts of a rare earth modifier, 2-3 parts of an adhesive, 4-6 parts of linear polyethylene and 4-6 parts of fumed silica. The seal ring is prepared by the following steps: uniformly mixing the components in a kneading machine; treating for 2 hours at 140-170 DEG C to prepare a sizing material; and preparing the seal ring according to a conventional process. The seal ring provided by the invention has the advantages of high strength and low compressive deformation, is high and low temperature resistant and excellent in performance and is free of breakage and deformation phenomena for a long operating time.

Description

technical field [0001] The invention relates to the technical field of automobile accessories, in particular to an automobile oil seal sealing ring. Background technique [0002] The traditional sealing ring uses ordinary nitrile rubber (NBR) as the main raw material, and its formula design often takes tear resistance, wear resistance and extrusion resistance as key considerations, which are not fully considered in the formula design process. The sealing rings used in the medium and working conditions are far from meeting the requirements in terms of self-lubricating performance, heat resistance, and aging resistance. Therefore, they are prone to twisting and cracking due to increased torque during assembly, and their service life is short. Contents of the invention [0003] The technical problem to be solved by the invention is to provide an automobile oil seal sealing ring with low cost and stable performance.
