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
The present invention relates to a kind of cold resistant rubber, belong to rubber technology field.
Background technology
Rubber (Rubber): the snappiness polymer materials with reversible deformation.At room temperature high resilience can produce compared with large deformation under very little External Force Acting, removes resilient after external force.Rubber belongs to complete amorphous polymer, and (T g) is low for its second-order transition temperature, and molecular weight is often very large, is greater than hundreds of thousands of.Rubber industry is one of important foundation industry of national economy.It not only provides daily life the indispensable light industry rubber product such as daily, medical for people, and provides various rubber production unit processed or rubber components to the heavy industry such as digging, traffic, building, machinery, electronics and new industry.Yet the low temperature resistant effect of most of rubber is poor, can not meet the demands, be therefore badly in need of low temperature resistant rubber.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, a kind of rubber is provided, and has resistance to low temperature, can also keep appropriate elasticity simultaneously.
For solving prior art problem, technical scheme provided by the invention is, a kind of cold resistant rubber, and its raw material by following parts by weight is made:
Ethylene-propylene rubber(EPR) 20-40 part, nitrile rubber 20-30 part, cis-1,4-polybutadiene rubber 40-50 part, magnesium oxide 11-18 part, white carbon black 30-40 part, anti-aging agent 3-5 part, calcium carbonate 12-20 part, naphthenic hydrocarbon 2-5 part, stearic acid 1-3 part.
Optimisation technique scheme of the present invention is, a kind of cold resistant rubber, and its raw material by following parts by weight is made:
30 parts, ethylene-propylene rubber(EPR), 25 parts of nitrile rubbers, 45 parts of cis-1,4-polybutadiene rubbers, 15 parts, magnesium oxide, 35 parts of white carbon blacks, 4 parts, anti-aging agent, 16 parts, calcium carbonate, 4 parts, naphthenic hydrocarbon, 2 parts of stearic acid.
The invention has the beneficial effects as follows: elastomeric material of the present invention has resistance to low temperature, can also keep appropriate elasticity simultaneously.
