LAYER, CLINCH PART AND TREAD FORMED USING DEFINED RUBBER MIXTURE AND PNEUMATIC TYRE WITH SAID COMPONENTS

摘要

FIELD: chemistry.SUBSTANCE: rubber mixture for a tyre component such as a layer, a clinch part or a tread, contains 100 pts.wt natural rubber and/or modified natural rubber, 25-80 pts.wt silicon dioxide having BET specific surface area of not more than 150 m/g, 1-4 pts.wt soot, vulcanising agents and vulcanisation accelerators.EFFECT: rubber mixture for tyre components has good processability during production and low hysteresis loss for the tyre layer, enables to preserve physical characteristics - rigidity, hardness and mechanical strength for the clinch part and tread; low consumption of materials from oil resources during production.9 cl, 2 dwg, 3 tbl, 14 ex
