Abstract

The invention relates to a modified rubber which comprises the following components in parts by weight: 10-16 parts of polyisoprene, 6-10 parts of polypropylene, 0.2-0.5 part of anti-aging agent, 1-3 parts of silane coupling agent, 50-65 parts of ethylene propylene diene monomer, 0.8-2.2 parts of hydroxy silicon oil, 1-3 parts of carbon black, 0.5-1 part of zinc oxide and 0.8-2 parts of vulcanizing agent. The high-toughness impact-resistant rubber provided by the invention has the advantages of favorable toughness, favorable impact resistance, favorable anti-aging function, favorable weather resistance and wide application range.

Description

A kind of modified rubber
Technical field
The present invention relates to a kind of rubber, be specifically related to a kind of modified rubber.
Background technology
Rubber is a kind of resilient polymkeric substance.Rubber can be obtained from the myron of some plants, can be also artificial, both considerable application and products, and such as tire, packing ring etc., become Important Economic crop then.Rubber has good elasticity, and very light weight, and cost is lower, and moulding ratio is easier to, and can in multiple fields, use, and the kind of rubber is varied now, and rubber use range is very extensive, and what in industry, agricultural, use is very frequent.Some rubber impact is better, some rubber is slight height but toughness deficiency, but some rubber good toughness undercapacity, but rubber is easily aging, causes toughness and impact to decline.
Summary of the invention
The object of this invention is to provide a kind of modified rubber, improved toughness and the shock resistance of rubber.
The present invention is achieved through the following technical solutions:
A kind of modified rubber, comprises: polyisoprene 10-16 part, polypropylene 6-10 part, anti-aging agent 0.2-0.5 part, silane coupling agent 1-3 part, terpolymer EP rubber 50-65 part, hydroxy silicon oil 0.8-2.2 part, carbon black 1-3 part, zinc oxide 0.5-1 part, vulcanizing agent 0.8-2 part by weight.
Described vulcanizing agent is sulphur.
Described anti-aging agent is 2,2,4-trimethylammonium 1,2-dihydro quinoline.
Beneficial effect of the present invention: high-tenacity and shock-resistance rubber provided by the invention has good toughness and good shock resistance, impact property improves more than 40% than terpolymer EP rubber, and product has good anti-old function, there is good weathering resistance, use range is wide.
