中文摘要:
      采用共混法制备环保丁基再生橡胶/聚氯乙烯（PVC）热塑性弹性体阻尼材料（以下简称热塑性弹性体），研究环保丁基再生橡胶用量、PVC改性剂种类和用量、填料（磁粉和硅藻土等）用量对热塑性弹性体性能的影响。结果表明：随着环保丁基再生橡胶用量的增大，热塑性弹性体的力学性能和压缩永久变形下降，密度增大，阻燃性能无明显变化；当环保丁基再生橡胶用量为40份时，热塑性弹性体的综合性能良好且性价比高。采用20份氯化聚乙烯与10份苯乙烯-乙烯-丙烯-苯乙烯共聚物并用作为PVC改性剂，热塑性弹性体的综合性能较优。随着填料用量的增大，热塑性弹性体的密度、阻燃性能和磁性提高，但力学性能下降；当填料用量为120份时，热塑性弹性体的综合性能较优，阻尼温域为－55～100 ℃，损耗因子≥0.3，阻尼性能好。
英文摘要:
      The environmentally friendly butyl reclaimed rubber/polyvinyl chloride（PVC） thermoplastic elastomer damping materials（hereinafter referred to as thermoplastic elastomer） were prepared by the blending method. The effects of the amount of environmentally friendly butyl reclaimed rubber，the type and amount of PVC modifiers，and the amount of fillers （magnetic powder and diatomaceous earth etc.） on the properties of thermoplastic elastomers were studied. The results showed that as the amount of environmentally friendly butyl reclaimed rubber increased，the mechanical properties and compression set of thermoplastic elastomers decreased，the density increased，and the flame retardant performance changed little. When the amount of environmentally friendly butyl reclaimed rubber was 40 phr，the thermoplastic elastomer exhibited good comprehensive properties and high cost-effectiveness. The optimal comprehensive properties of the thermoplastic elastomer were achieved by using a blend of 20 phr chlorinated polyethylene and 10 phr styrene-ethylene-propylene-styrene copolymer as PVC modifiers. As the amount of fillers increased，the density，flame retardancy，and magnetic properties of thermoplastic elastomers were improved，but the mechanical properties decreased. When the amount of fillers was 120 phr，the comprehensive properties of thermoplastic elastomer were optimal，with a damping temperature range of －55～100 ℃，a loss factor ≥ 0.3，and good damping performance.
