Ozone-resistant rubber

Abstract

The invention relates to an ozone-resistant rubber which is prepared from the following raw materials in parts by weight: 40-60 parts of natural rubber, 10-25 parts of ethylene propylene diene monomer, 6-10 parts of zinc diethyl dithiocarbamate, 8-11 parts of anti-aging agent, 3-6 parts of PVC (polyvinyl chloride) powder, 6-9 parts of nickel dibutyldithiocarbamate, 9-12 parts of microcrystalline wax and 5-7 parts of N-tert-butyl-2-benzothiazolylsulphenamide. The rubber material can enhance the ozone resistance of the manufactured automobile shock-absorption part rubber, thereby prolonging the service life.

Description

technical field [0001] The invention relates to an ozone-resistant rubber, which belongs to the technical field of rubber. Background technique [0002] Rubber: A highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (T g) is low, and its molecular weight is often large, greater than hundreds of thousands. The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. In the prior art, the rubber used ...

AI Technical Summary

Problems solved by technology

In the prior art, the rubber used to manufacture automobile shock absorbers is usually natural rubber. Due to the chemical structure of natural rubber itself, its ozone resistance is poor, thus affecting the physical and mechanical properties and service life of automobile shock absorbers.
