摘　　要：通过熔融挤出制备了无卤阻燃热塑性弹性体(TPE)复合材料。通过锥型量热仪、氧指数测定仪、垂直燃烧仪和扫描电子显微镜(SEM)等研究了其性能。结果表明:与未具备阻燃性能的TPE相比,二乙基次磷酸铝(ADP)阻燃TPE复合材料的总热释放(THR)、热释放速率峰值(PHRR)显著降低,点燃时间(TTI)、火灾性能指数(FPI)、质量保留率、极限氧指数(LOI)和UL94阻燃等级显著提高。硼酸锌与ADP对TPE复合材料具有明显的协同阻燃作用。TPE复合材料总体保持了较高力学性能,热老化后拉伸强度和断裂伸长率降低幅度均远低于30%,满足线缆护套材料的性能要求。Halogen-free flame-retardant thermoplastic elastomer(TPE)composite materials were prepared by melt extrusion,and its properties were studied using cone calorimeter,oxygen index analyzer,vertical combustion instrument and scanning electron microscope(SEM).The results show that compared with non flame retardant TPE,the total heat release(THR)and peak heat release rate(PHRR)of diethylaluminum phosphate(ADP)flame retardant TPE composite materials are significantly reduced,while the ignition time(TTI),fire performance index(FPI),quality retention rate,limit oxygen index(LOI)and UL94 flame retardant rating are significantly improved.Zinc borate and ADP have a significant synergistic flame retardant effect on TPE composite materials.TPE composite materials overall maintain high mechanical properties,with a decrease in tensile strength and elongation at break of less than 30%after thermal aging,meeting the performance requirements of cable sheath materials.
