? 2022In the present research, the influence of nanodiamond (ND) and a physical hybrid of ND and fumed nano-SiO2 were investigated on the performance of a typical tire tread compound. The styrene-butadiene rubber (SBR) and cis-butadiene rubber (BR) blend filled with a commercial grade highly dispersive silica at 70 phr loading were used as typical tire tread compound. ND was substituted partially with silica at two different concentrations of 5 and 10phr. Meanwhile, 5 phr of ND/nano-SiO2 hybrids with the weight ratio of 2.5/2.5 and 1/4 were substituted with silica. ND-Filled compounds exhibit increased scorch and cure time compared to controls. Improvement in different characteristics of the control sample such as mechanical properties, thermal conductivity and crosslink density estimated based on the tube theory and swelling test was observed for 5 phr loading of ND. The sample containing 5 phr loading of ND exhibited improved Young's modulus (～ 40%) and enhanced thermal stability (～ 40°C and ～ 10 °C increase in temperature at weight loss of 10% and 50%, respectively). Moreover, ND at 5phr loading provided notable progress (～ 10%) in wet traction, which could be essential for tire tread manufacturers. ND/nano-SiO2 hybrid enhanced the hardness and thermal stability in synergistic manner.
