Abstract
The invention discloses a shock absorber top rubber formula which comprises, by weight parts, 60-80 parts of nitrile rubber, 40-60 parts of polyurethane rubber, 10-15 parts of zinc oxide, 3-10 parts of 4,4-bis-diphenylamine, 5-10 parts of poly-allene siloxane, 5-10 parts of chlorine ethyl formate, 4-8 parts of sulphur, 3-5 parts of softening oil, 5-10 parts of carbon black N330 and 1-5 parts of accelerant TMTD. Rubber prepared according to the shock absorber top rubber formula is applicable to the field of automobiles, has good oil resistance and abrasion resistance and is long in service life.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a shock absorber top glue formula. Background technique [0002] With the rapid development of the automobile industry, people have put forward better requirements for the safety performance and technical performance of automobile rubber, and automobile rubber has developed towards high performance, such as the oil resistance and excellent wear resistance of shock absorber top rubber, etc. Wait. The so-called rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can return to its original shape after the external force is removed. Excellent high-performance tire materials have In addition to excellent comprehensive performance, it is also necessary to consider the processing performance of rubber. [0003] At present, although there are various kinds of wea...
