摘　　要：采用钛酸酯偶联剂对氧化锌(ZnO)进行表面改性,改性ZnO与低密度聚乙烯(LDPE)制备LDPE/ZnO复合材料。分析ZnO形貌及添加量对复合材料力学性能、阻尼性能、隔声性能及热稳定性的影响。结果表明:改性ZnO与LDPE具有良好的界面相容性,ZnO可以提升LDPE/ZnO复合材料的抗拉强度、隔声性能及热稳定性,四针状氧化锌(T-ZnO)添加量为5%时,复合材料的力学性能最好,综合性能最优。The surface of zinc oxide(ZnO) was modified by titanate coupling agent, and LDPE/ZnO composites were prepared by modified ZnO and low density polyethylene(LDPE). The effects of ZnO morphology and addition amount on the mechanical properties, damping properties, sound insulation properties and thermal stability of the composites were analyzed. The results show that the modified ZnO has good interfacial compatibility with LDPE. ZnO can improve the tensile strength, sound insulation and thermal stability of LDPE/ZnO composites. When the content of tetrapod-like ZnO(T-ZnO) is 5%, the mechanical properties of the composites are the best and the comprehensive performance is the best.
