Abstract
The invention relates to an anti-aging rubber which is prepared from the following raw materials in parts by weight: 20-40 parts of chloroprene rubber, 3-5 parts of N-isopropyl-N'-phenyl-p-phenylenediamine, 0.5-2 parts of dicumyl peroxide, 10-15 parts of carbon black, 4-7 parts of stearic acid, 5-9 parts of anti-aging agent, 3-6 parts of graphite powder and 2-4 parts of adhesive. The rubber material has the advantages of excellent aging resistance, excellent tensile strength at break and high elongation at break.
Description
Technical field
The present invention relates to a kind of ageing-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 is g) low, and molecular weight is often very large, is greater than hundreds of thousands of for its second-order transition temperature.But in use, rubber can be aging gradually, and performance reduces greatly, is therefore badly in need of a kind of ageing-resistant rubber, slows down ager process, improve work-ing life.
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 good ageing-resistant performance, and tensile strength at yield, tensile yield are high.
For solving prior art problem, technical scheme provided by the invention is, a kind of ageing-resistant rubber, and its raw material by following parts by weight is made:
Chloroprene rubber 20-40 part, N-sec.-propyl-N`-diphenyl-para-phenylene diamine 3-5 part, dicumyl peroxide 0.5-2 part, carbon black 10-15 part, stearic acid 4-7 part, protective agent 5-9 part, Graphite Powder 99 3-6 part, tackiness agent 2-4 part.
Optimisation technique scheme of the present invention is, a kind of ageing-resistant rubber, and its raw material by following parts by weight is made:
30 parts of chloroprene rubbers, 4 parts of N-sec.-propyl-N`-diphenyl-para-phenylene diamines, 1.2 parts of dicumyl peroxides, 13 parts of carbon blacks, 5.5 parts of stearic acid, 7 parts of protective agents, 4.5 parts of Graphite Powder 99s, 3 parts of tackiness agent.
The invention has the beneficial effects as follows: elastomeric material of the present invention has good ageing-resistant performance, tensile strength at yield, tensile yield are high.
