摘　　要：研究钼系高乙烯基聚丁二烯橡胶(HVBR)与天然橡胶(NR)并用在输送带胶料中的应用。结果表明,HVBR/NR并用可改善输送带胶料的加工性能,基本不影响胶料的物理性能,可明显增大输送带胶层与纤维帘布的剥离强度,特别是热氧老化后HVBR/NR并用胶层的剥离强度明显大于NR单用胶层,HVBR的应用优势明显。The application of molybdenum-catalyzed high vinyl polybutadiene rubber(HVBR)blending with natural rubber(NR)in the conveyor belt compound was studied.The results showed that blending HVBR with NR could improve the processability of the conveyor belt compound without affecting its physical properties and could significantly increase the peeling strength between the rubber layer and the fiber cord of the conveyor belt.In particular,the peeling strength of the HVBR/NR blend layer was significantly greater than that of the single NR layer after thermo-oxidative aging,and the application advantage of HVBR was obvious.
