Description
Technical field
The present invention relates to rubber materials, it carries out the elastomeric material of modification particularly to relate to modification butadiene-isoprene rubber and production method thereof and use.
Background technology
In the current international big environment be becoming tight at natural rubber and petroleum resources day, domestic natural rubber price, also by per ton about ten thousand a few years ago yuan, rises to current about 40,000 per ton; Synthetic rubber also rises to about 30,000 per ton.Cause many rubber plants normally to produce, even face the serious situation of bankruptcy.
Rubber compounding, have passed through the development of decades, improving and use, in order to winning of unexpectedly striving between the same industry, tries every possible means to reduce costs one after another.But by the restriction of material property, rubber compounding has arrived the stage changing and can not change already.Therefore, in the urgent need to releasing type material, to adapt to the social demand of current rubber industry.
Butadiene-isoprene rubber because of macromolecular chain shorter, still can not use as rubber separately at present, but part natural rubber can be replaced, be applied in the various rubber items such as tire, adhesive tape, oil sealing, and shown the characteristic not available for many general conventional rubbers:
1) greatly strengthen with the wetting capacity of carbon black, dust from flying obviously reduces, thus improves the velocity of diffusion of carbon black in rubber, shortens mixing time (small-sized internal mixer, the banburying time reduced to 8 minutes from 12 minutes).
2) Mooney viscosity of rubber unvulcanizate decreases, thus suitably can improve the consumption of synthetic rubber consumption or carbon black and strengthening agent, and does not reduce the performance of cross-linked rubber.
3) self-adhesion of rubber unvulcanizate and mutual viscosity can be all fine, and during calendering, rubber unvulcanizate power of oozing in cord strengthens, and cord kiss-coating is even, and the adhesion strength between glue-line is also improved preferably.The process operability such as extrusion, joint are all obviously better than normal rubber unvulcanizate.
Summary of the invention
The object of the present invention is to provide a kind of modification butadiene-isoprene rubber, production method and use it to carry out the elastomeric material of modification.
The object of the invention is to be realized by following approach:
Modification butadiene-isoprene rubber, its component and mass percent are:
