B. by other rubber master batch components except pre-dispersed s. and predispersed accelerator by a meshing mixer through multistage mixing or two series connection the mixing productions of meshing mixer once-through method, Banbury mixer packing volume 60 ~ 80%;
C. add sulphur technique: refining 5 ~ 20min is opened in mill, roll spacing 1.0 ~ 5.0mm, less than 100 DEG C add pre-dispersed s., predispersed accelerator, evenly mixing, 60 ~ 80 DEG C of binder removal slices.
10. the production technique of high-performance tire rubber combination according to claim 9, it is characterized in that: the concrete technology of described step b is as follows: milling maternal rubber technique: in Banbury mixer, add Butadiene-Styrene Rubber, high-cis-1,4-nickel system's cis-butadiene cement and natural gum carry out Banbury mixer and turn, pressurization rises floating weight, add oligomeric high dispersive type silicon-dioxide and silane coupling agent, pressurization rises floating weight and adds part TDAE oil, pressurization, constant temperature is evenly mixing, and binder removal to mill slice becomes one section of rubber master batch; In Banbury mixer, add one section of rubber master batch, banburying pressurization rises floating weight, adds zinc oxide, stearic acid and carbon black, anti-aging agent component, and pressurization rises floating weight and adds residue TDAE oil, pressurization, and control 135-145 DEG C constant temperature is evenly mixing automatically, and binder removal is to mill slice;
Multistage is mixing repeats above-mentioned technique.
