Abstract

The invention discloses a sealing element for automobiles. The sealing element comprises, by weight, 28 parts to 34 parts of polyvinyl chloride, 0.7 part of glass fiber, 68 parts to 75 parts of nitrile rubber, 4 parts to 7 parts of zinc oxide, 2.2 parts to 2.8 parts of 2,2'-dithio-dibenzo thiazole, 2.2 parts to 2.8 parts of tetramethylthiuram disulfide, 1 part to 2.3 parts of stearic acid, 2.5 parts of sulphur, 35 parts to 43 parts of carbon black, 2.2 parts to 2.5 parts of antiager RD, 2.2 parts to 2.5 parts of N-isopropyl-N`-phenylenediamine, 12 parts to 16 parts of dibutyl phthalate, 1.5 parts to 2.5 parts of diglycol, and 0.3 part to 0.5 part of triphenyl phosphite. The sealing element for automobiles can overcome the defect that the service life of the prior art is short due to poor oil resistance, and the integral usability of the sealing element is guaranteed.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a sealing element for automobiles. Background technique [0002] The choice of seal material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the seal. Automobile bearing seals are in contact with oil during use. At this time, oil can penetrate into the inside of the seal to cause swelling, resulting in a decrease in the strength and other mechanical properties of the seal. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a seal for automobiles, which has high oil resistance and ensures the overall performance of the seal. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] A sealing element for automobiles, comprising components proportioned in the following p...
