Description

technical field [0001] The invention relates to the field of rubber, in particular to a novel anti-oxidation rubber and a preparation method thereof. Background technique [0002] Rubber is 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 with a low glass transition temperature and often a large molecular weight, 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. [0003] With the ...
