| 摘 要： | 采用锥形量热仪研究了磷-溴-硅三种阻燃元素对聚丙烯(PP)释热速度、总烟产量、释热总量、一氧化碳、二氧化碳(Co、CO_2)的释放量等的影响。研究结果表明,含溴阻燃剂阻燃效果显著,但 CO 和总烟产量较高。含磷和氮的膨胀型阻燃剂的 CO 和总烟产量显著降低,但阻燃效果较差,分子筛的加入,可使磷采用锥形量热仪研究了磷-溴-硅三种阻燃元素对聚丙烯(PP)释热速度、总烟产量、释热总量、一氧化碳、二氧化碳(Co、CO_2)的释放量等的影响。研究结果表明,含溴阻燃剂阻燃效果显著,但 CO 和总烟产量较高。含磷和氮的膨胀型阻燃剂的 CO 和总烟产量显著降低,但阻燃效果较差,分子筛的加入,可使磷一溴协同体系的各项阻燃参数得到显著改善,若能将磷氮的膨胀型阻燃剂和分子筛二者结合,少加或不加六溴环卜二烷将是理想的选择。溴协同体系的各项阻燃参数得到显著改善,若能将磷氮的膨胀型阻燃剂和分子筛二者结合,少加或不加六溴环十二烷将是理想的选择。

| Abstract: | Effect of P,Br and Si on the heat release rate,total smoke emission,total heat release rate, and CO and CO_2 concentration for PP was studied by cone calorimeter.It showed that Br is an effective flame retardant element,but the CO and total smoke emission is high.The P-N intumescent system de- creased the CO and total smoke emission,however,had an inferior flame retardaney.With the addition of molecule sieve,parameters of the flame retardant become superior.The combination P-N intumescent system with molecu... |
