摘　　要：以季戊四醇、三氯氧磷、三聚氰胺为原料合成出集酸源、炭源、气源于一体的单分子膨胀型阻燃剂(PDM),通过红外及核磁分析方法对其组成进行了表征和分析,研究了合成反应时间、反应温度对产率的影响,结果发现最佳反应温度为85℃,最佳反应时间为7.5h。将合成出的阻燃剂应用于环氧树脂中,利用锥形量热仪对其阻燃及热解性能进行测试,结果表明环氧树脂中阻燃剂含量从20份增加到30份后,峰值热释放速率分别从1 310 kW/m2下降到474 kW/m2和351kW/m2,阻燃效果良好。Using pentaerythritol, phosphorus oxychloride and toluene as raw materials, a single-molecule intumescent flame retardant PDM was synthesized. Carbon source,acid source and gas source were integrated in PDM. Its structure was tested and （;haracterized by IFR and NMR. The effect of the synthesis reaction time and reaction temperature on the yield was explored. The results show that the best reaction temperature is 85℃. The best reaction time is 7. 5 h. This flame retardant was applied in epoxy resin. The flame retardant and pyrolytic properties was measured by cone calorimeter. It show that when the mass of PDM increases from 20 phr to 30 phr in the epoxy resin, the peak of heat release rate respectively declines to 474 kw/m2 and 351 kW/m2 from 1 310 kW/m2.
