摘　　要：研究钼系高乙烯基聚丁二烯橡胶(HVBR)胶料与几种常用橡胶胶料阻尼性能和物理性能的差异,以及无机填料品种和用量对HVBR胶料阻尼性能的影响。结果表明:与天然橡胶(NR)、丁苯橡胶(SBR)和丁基橡胶(IIR)胶料相比,HVBR胶料的损耗因子(tanδ)峰值大,阻尼性能好,有效阻尼温域略窄但在常温范围内,拉伸强度较小但可满足使用要求,耐热老化性能较好;蛭石粉和中空玻璃微珠可以明显改善HVBR胶料的阻尼性能,改性碳纳米管和云母粉不能改善HVBR胶料的阻尼性能;蛭石粉和中空玻璃微珠用量分别为3和15份时,HVBR胶料的tanδ峰值大,阻尼性能好,有效阻尼温域较宽。The damping property and physical properties of molybdenum-based high-vinyl polybutadiene rubber （HVBR） compound and several commonly used rubber compounds were studied. The effects of the amount and type of inorganic fillers on the damping properties of HVBR compounds were also investigated. The results showed that the loss factor （tanδ） of HVBR compound was higher than that of natural rubber （NR） , styrene butadiene rubber （SBR） and butyl rubber （IIR） compounds, and the damping performance was better in the range of normal temperature, but the effective damping temperature range was a little narrow. The tensile strength of HVBR compound was lower but it met the application requirements. The heat aging performance of HVBR compound was good. It was found that the addition of vermiculite powder and hollow glass beads could significantly improve the damping performance of HVBR compound, and addition of modified carbon nanotubes and mica powder presented little improvement. When the addition level of vermiculite powder and hollow glass beads was 3 and 15 phrs, respectively, the tanδ peak of HVBR compound was quite large, the damping performance was good, and the effective damping temperature range was wide.
