Abstract

The vulcanization properties of rubber compounds based on solution styrene-butadiene rubbers containing silica fillers have been studied. As objects of study, elastomer compositions based on rubber grades DSSK-2163 and oil-filled DSSK-2560-M27 were used. Two types of filler, Zeosil-1165MP and Zeosil Premium 200MP, were used in the work, differing in the specific adsorption surface area. The dosage of mineral fillers was 60, 65 and 70 phr. The silane grade X 50-S was used as a coupling agent. It has been determined that an increase in the dosage of the coupling agent leads to a reduction in optimum cure time of rubber compounds based on DSSK-2163 with different filler content by 3.9–10.9% for compositions with Zeosil-1165MP and by 2.6–9.9% for compositions with Zeosil Premium 200MP, and for compounds based on DSSK-2560-M27, an increase in the content of the coupling agent leads to a reduction in optimum cure time for compositions with Zeosil-1165MP by 2.6–7.1% and with Zeosil Premium 200MP by 2.3–6.5%. It has been established that an increase in the filler content from 60 to 70 phr, the optimum cure time increases by 10.2–35.6% for compositions based on DSSK-2163 and up to 16.8% for compositions based on DSSK-2560-M27.
