| 摘 要： | 考察了丁腈橡胶/聚氯乙烯共混物中硫化体系、炭黑种类、增塑剂用量及组分比对材料阻尼性能的影响.结果表明,丁腈橡胶/聚氯乙烯共混物的交联密度增大,其损耗因子峰向高温方向移动,峰值升高,损耗因子不小于0.5的温度区域变窄;相比高耐磨炭黑而言,用半增强炭黑作填料可使丁腈橡胶/聚氯乙烯共混物呈现更好的阻尼性能;随着增塑剂邻苯二甲酸二辛酯用量的增加,共混物的损耗因子峰值升高,但该峰向低温方向移动;丁腈橡胶/聚氯乙烯共混物(质量比为70/30)的损耗因子不小于0.5的阻尼温域相对较宽,适用于常温,且力学性能较好.

| Abstract: | The damping properties of acrylonitrile-butadiene rubber/polyvinyl chlorIDe(NBR/PVC) blends were investigated from curing systems, carbon black types, plasticizer amount and mass ratios of NBR to PVC, respectively. The results showed that as the crosslinking density increased, the position of loss factor (tan δ) peak shifted to high temperature with a higher value, but the temperature range of tan δ no less than 0.5 became narrow. Damping properties of blends filled with semi-reinforcing furnace black were better than that with high abrasion furnace black.Increasing dioctyl phthalate amount could improve the tan δ peak, but its position shifted to low temperature. NBR/PVC(70/30) showed the wIDest temperature range of tan δ no less than 0.5, which was suitable for using at room temperature with good mechanical properties. |
