摘　　要：研究了增塑剂、无机填料以及酚醛树脂对聚氯乙烯(PVC)热塑性弹性体(TPE)力学性能及动态力学性能的影响。结果表明:聚酯增塑PVC弹性体材料体系的tanδ峰值明显高于DOP、DOTP、TOTM三种增塑剂,且阻尼性能最优;随着聚酯用量的增加,PVC弹性体的tanδ峰值逐渐提高,tanδ峰逐渐向低温方向移动。PVC热塑性弹性体中加入适量无机填料可以提高其tanδ峰值;可以用酚醛树脂调整PVC弹性体阻尼材料tanδ峰所对应的温域,从而改善其阻尼性能。The effects of plasticizers,inorganic fillers and phenolic resin on mechanical and dynamic mechanical properties of polyvinyl chloride(PVC)thermoplastic elastomer(TPE)were investigated.The results show that:tanδmax of polyester plasticized PVC elastomer material system is obviously higher than DOP,DOTP and TOTM plasticizers,and the damping performance is the best.With the increase of polyester content,the tanδmax of PVC elastomer increases gradually,and the tanδmax moves to low temperature gradually.Adding inorganic fillers to PVC thermoplastic elastomer can increase its tanδmax,and phenolic resin can be used to adjust the temperature range corresponding to tanδmax of PVC elastomer damping material to improve its damping performance.
