摘　　要：以丙二醇丁醚缩水甘油醚改性的聚乙烯亚胺的CO2加合物(R-PEI-CO2)作为发泡剂,氯代烷基多聚磷酸酯(YK-8006)用作反应型阻燃剂,对所制备的硬质聚氨酯泡沫塑料的阻燃效果进行研究。测试结果表明,R-PEI-CO2除了作为环境友好的发泡剂以外,其含有的氮元素还可以对制备的聚氨酯泡沫起到一定的阻燃作用。通过适当的配方设计,可以使R-PEI-CO2制备的硬泡阻燃性能好于同等密度的水发泡的硬泡。The flame retardant effect of rigid polyurethane foam was studied,which prepared by using propanediol butyl ether grafted polyethyleneimine CO2 adduct(R-PEI-CO2)as blowing agent and chloroalkyl polyphosphate(YK-8006)as the reactive flame retardant.The results showed that the R-PEI-CO2 used as an environmental friendly blowing agent could also play a certain role in flame retardancy due to its high nitrogen content.When the formulations were designed properly,the flame retardancy of R-PEI-CO2 blown rigid polyurethane foam was better than the water-blown foam with the same density.
