以六（对羟甲基苯氧基）环三磷腈（ HHPCP ）与甲基磷酸二甲酯（ DMMP ）组成复配阻燃剂制备了阻燃聚氨酯硬泡。利用FT?IR研究了HHPCP与多亚甲基多苯基多异氰酸酯（ PAPI）的交联反应，通过扫描电子显微镜、极限氧指数测试仪、热重分析仪以及微型量热仪研究了 HHPCP／DMMP不同配比对聚氨酯硬泡的阻燃性能和热性能的影响。结果表明，当在50份聚醚多元醇中加入阻燃剂HHPCP与DMMP各10份时，阻燃聚氨酯硬泡的氧指数、抗压强度、密度达到最优，氧指数为24?5％，且总释放热由21?6 kJ／g降低到16?9 kJ／g。

Flame retardant polyurethane( RPUF) foam was prepared with combined flame retardant by hex( p?hydroxymethyphenoxy) cyclotriphosphazene(HHPCP) and dimethyl methyl phosphate(DMMP). The crosslink re?action of polymethylene polyphenyl isocyanate( PAPI) and HHPCP was studied by FTIR. The flame retardant prop?erties and thermal performance of RPUF with different HHPCP/DMMP ratio were investigated by the limiting oxy?gen index( LOI) , scanning electron microscopy,thermal gravimetric analysis and micro?calorimeter. The results in?dicated that, when the adding amount of HHPCP and DMMP in 50 parts poyether polyol was 10 parts respectively, flame retardant properties, compressive strength and density were the optimal, the LOI of the RPUF reached 24?5% and total release thermal peak decreased to 16?9 kJ/g from 21?6 kJ/g.
