Description

A kind of rubber for tire

Technical field

The present invention relates to a kind of rubber for tire.

Background technology

Present rubber industry is one of important foundation industry of national economy, it is not only for people provide daily life indispensable daily, medical rubber product such as light industry such as grade, and to digging, traffic, building, machinery, the heavy industry such as electronics and new industry provide various rubber production unit or rubber components, rubber is more and more widely used, but there are some defects, because increasing in recent years along with automobile, the consumption of rubber gets more and more, the quality of tire also declines thereupon to some extent, use under complicated and exacting terms but tire is everlasting, it subjects various extruding in motion, friction, load, the impact of wetland and high/low temperature, so the refinement more that the rubber for tire on market will do, targetedly.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of rubber for tire, has high thermal resistance, and with low cost, Toughness Ratio is better.

For solving prior art problem, technical scheme provided by the invention is, a kind of rubber for tire, and it is made up of the raw material of following parts by weight:

Natural rubber 10-21 part, two mercaptan 2-5 parts, softening agent 4-8 part, paracril 25-37 part, phenylformic acid 3-8 part, promotor 3-6 part, polyisoprene rubber 13-17 part, terpolymer EP rubber 10-15 part, stearic acid 2-5 part, spray carbon black 30-40 part, 320 type chloroprene rubber 12-15 parts, natural fluororubber 23-34 parts, calcium carbonate 2-5 part, fire retardant 5-6 part.

The invention has the beneficial effects as follows: rubber for tire of the present invention, has high thermal resistance, with low cost, and Toughness Ratio is better.
