Automobile shock-absorbing rubber products are elastic buffer devices installed in specific parts of the body made of rubber as the main raw material, which can play a role in reducing or eliminating vibration and noise during the driving of the car. Chlorinated butyl rubber is prepared by chlorine gas through butyl rubber solution, which has the characteristics of good air tightness, heat resistance, weather resistance, aging resistance, good shock absorption performance, etc., and is an ideal raw material for the production of various types of automobile shock absorbing rubber products.
1. The specific application of chlorobutyl reclaimed rubber in automobile shock absorbing products
Chlorobutyl reclaimed rubber is a waste chlorobutyl rubber products such as pharmaceutical butyl stoppers processed by crushing, thinning, desulfurization, refining and other processes, which retains the basic performance characteristics of chlorobutyl rubber, and can be used in combination with chlorobutyl rubber E4LYY1113 produce automobile shock-absorbing rubber products to reduce costs. Chlorobutyl rubber/chlorobutyl reclaimed rubber has good elasticity and can effectively absorb the vibration caused by uneven road surface during driving; Good damping and shock absorption, isolate sound wave conduction, and reduce internal noise.
The shock-absorbing rubber products produced with chlorobutyl rubber/chlorobutyl reclaimed rubber combined with rubber as the main raw material are widely used in automobiles, mainly including shock-absorbing upper brackets in the suspension system, rear axle elastic couplings, inflatable shock absorbers, shock absorbing pads, spring pads, etc., the central bearing of the transmission shaft in the power transmission system, and various rubber bushings in the steering system. The vulcanization formula of shock-absorbing rubber products is different for different use occasions.
