摘要: 以三聚氯氰和对苯二胺为原料,以丙酮为溶剂,采用一步法合成了一种具有超支化结构的新型芳胺三嗪聚合物,用红外光谱证实了其结构,将该产物与聚磷酸铵(APP)复配成膨胀型阻燃剂(IFR),研究了其对聚丙烯(PP)阻燃性能的影响。结果表明,在氮气氛围下,合成的新型芳胺三嗪聚合物在600 ℃的残炭量为44.8 %,具有较好的成炭阻燃性能;添加该类新型IFR后,PP的极限氧指数从17.5 %提高到27.0 %,热释放时间延后625 s,热释放速率峰值降低85.7 %。

Abstract: A new hyperbranched aromatic amine triazine polymer was designed and synthesed by taking cyanuric chloride and Pphenylenediamine as raw material in acetone solvent, and its structure was confirmed by infrared spectroscopy. The intumescent flame retardant(IFR) which was composed of ammonium polyphosphate(APP) and the prepared hyperbranched polymer was used for the preparation of expansion flame retardant polypropylene (PP). Results showed that the target product was capable of excellent flame retardant and its carbon residue amount at 600 ℃ in N2 atmosphere was 44.8 %. The limiting oxygen index of PP was enhanced to 27.0 % from 17.5 % after proper addition of IFR, the heat release time was delayed by 625 s, and the peak of heat release rate was decreased by 85.7 %.
