摘　　要：合成了六(4-甲氧基苯氧基)环三磷腈(HMPCP)和六(4-羟基苯氧基)环三磷腈(HHPCP)。将HMPCP和HHPCP应用于TDE-85环氧树脂中,研究添加两者后环氧树脂的阻燃性能,结果表明HHPCP阻燃效果优异,添加8%(wt,质量分数,下同)HHPCP的环氧树脂氧指数从18.2%提高至23.7%,450℃时残炭率高达12%;HHPCP阻燃机理为膨胀阻燃机理。Hexa（4-methoxyphenoxy）cyclotriphosphazene（HMPCP）and hexa（4-hydroxyphenyl oxy）cyclotriphosphazene（HHPCP）were synthesized.HMPCP and HHPCP were respectively added in TDE-85 resin as a flame retardant,and the thermal degradation properties and mechnism were characterized.IT showed that the performance as aflame retardant was well.The mechanism was the expansion mechanism,and the LOI of epoxy oxygen with 8% HHPCP increased from 18.2%to 23.7% which charyield was up to 12% at 450℃.
