摘　　要：制备无卤P-N阻燃环氧树脂(EP)复合材料,利用锥形量热(CONE)研究无卤阻燃剂DDPPC环氧树脂复合材料的火灾性能及成炭效果。结果表明:当DDPPC质量分数为25%时,阻燃EP的av-HRR、THR、av-EHC、av-SEA、avMLR相对未阻燃EP分别降低73.9%、71.6%、37.0%、48.7%、59.1%,呈现出良好的阻燃效果和抑烟、抑毒作用。宏观形貌研究表明:25%DDPPC/EP燃烧后形成了大体积圆锥形闭孔炭层。Epoxy resin was flame retarded with the novel arborescent P-N flame retardant hexalis-（4-（ 5,5-dimehtyl-l,3- dioxaphospho-rinanyl-2-oxy-phosphate-ester-phenoxy））-eyelotriphosphazene （DDPPC）. The CONE experimental resutts demonstrated that the DDPPC was effective on the flame retardancy of epoxy resin when the content of the fire retardant was 25% ,which the av-HRR, av-EHC, av-SEA and av-MLR of the EP retarded lowed 73.9% , 71.6% , 37.0% , 48.7% and 59.1% respectively than those of pure EP. In addition, SEM observation revealed that the continuous, intact, strong and closed charred layers were formed in EP specimen filled with DDPPC after burning.
