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
The present invention relates to auto parts machinery field, be specifically related to a kind of automobile sealing member.
Background technology
The selection of sealing member material to its sealing property and work-ing life important in inhibiting.The performance of material directly affects the use properties of sealing member.Automobile bearing sealing member in use will contact with oils, and at this moment oils can penetrate into sealing member inside to make it produce swelling, causes the intensity of sealing member and other mechanical properties to reduce.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of automobile sealing member, the seal has high-strength oil resistance, ensures the use properties of sealing member entirety.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of automobile sealing member, comprises each component by following parts by weight proportioning:
Polyvinyl chloride: 28-34 part
Glass fibre: 0.7 part
Paracril: 68-75 part
Zinc oxide: 4-7 part
2,2'-dithio-bis-benzothiazole: 2.2-2.8 part
