摘要：

The effect of nitrile rubber (NBR) on the properties of silica-filled natural rubber (NR) compounds was studied in the presence of a new silane coupling agent, 3-octanoylthio-1-propyltriethoxysilane (NXT). The properties of silica-filled NR compounds were improved by adding NBR. The torque at equilibrium of compounds decreased with increasing NBR content. The dispersion of silica was improved by adding NBR. The scorch time and optimum cure time became shorter with increasing NBR content. The crosslink density of silica-filled NR vulcanizates also increased with increasing NBR content. The modulus and hardness of NR vulcanizates were increased by adding NBR. The wet traction of the NR vulcanizates containing NBR was better than that without NBR, but rolling resistance of the vulcanizates containing NBR was worse than that without NBR.
