摘　　要：以六氯环三磷腈和邻苯二胺为为起始原料,甲苯为溶剂,三乙胺为缚酸剂,一步法合成三邻苯二胺基环三磷腈(HACTP)。采用HPLC、FT-IR、MS、31P-NMR和1H-NMR对化合物进行了表征。所得HACTP和聚磷酸铵(APP)、阻燃协效剂复配成膨胀型阻燃剂(IFR),添加到EVA材料中进行阻燃研究。通过对不同配方的试验,得到阻燃效果较好的阻燃剂配方:HACTP为32.84%,APP为50.04%,阻燃协效剂为17.12%。用该配方阻燃的EVA,LOI为36.8%,拉伸强度为5.46 MPa,断裂伸长率为594.95%,整体性能优良。Tri （o-diamino-phenyl）-cyclo-triphosphazene （HACTP） was synthesized by means of one-step method,and to use hexachlorine-cyclo-triphosphazene as raw material,toluene as solvent,triethylamine as acid binder.The synthesised HACTP was chararteristized by HPLC,FT-IR,MS,31P-NMR and1 H-NMR.Compounded this synthesised HACTP with ammonium polyphosphate（APP） and flame retardantant synergist to a infumescent flame retardants （IFR）,then blended it with EVA material to research its flame retardant performance.Through many tests of different formulas,at last obtained the optimum formulu is：HACTP 32.84％,APP 50.04％,flame retardant synergist 17.12％.The performances of the EVA added this composite flame retardants are：LOI is 36.8％,stretch strength is 5.46 MPa,percent of elongation at break is 594.95 ％,the comprehensive performance of this flame retardant EVA composite is excellent.
