Abstract
The invention provides low temperature resistant rubber. The low temperature resistant rubber is prepared from the following raw materials in parts by weight: 20-40 parts of ethylene propylene rubber, 20-30 parts of nitrile butadiene rubber, 40-50 parts of butadiene rubber, 11-18 parts of magnesium oxide, 30-40 parts of white carbon black, 3-5 parts of anti-aging agent, 12-20 parts of calcium carbonate, 2-5 parts of cycloalkane and 1-3 parts of stearic acid. The low temperature resistant rubber has the beneficial effects that the rubber material has low temperature resistance and simultaneously can maintain moderate elasticity.
Description
technical field [0001] The invention relates to a low-temperature-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. However, most rubbers hav...
