摘　　要：以多壁碳纳米管(MWCNTs)作为纳米阻燃材料,同时加入了磷酸三苯酯和聚磷酸铵协同阻燃,使用熔融共混法制备了PP阻燃样品。采用氧指数仪和微型量热仪研究了MWCNTs和阻燃剂对PP阻燃性能的影响,当MWCNTs与协同阻燃剂共同阻燃PP时,材料的氧指数(LOI)明显提高,热释放速率大幅下降,同时力学强度也有所提高。The multi-wall carbon nanotubes was used as nano-retardant materials, while adding triphenyl phosphate, ammonium polyphosphate as flame retardants, PP flame retardant sample was prepared by melt blending method. The effect of MWCNTs and flame retardant agent on the flame retardance of PP was studied by LOI and micro-calorimetry（MCC）. When MWCNTs and flame retardant agent were applied to PP, The LOI increased, and the heat release rate（HRR） decreased significantly, while the mechanical properties improved.
