摘　　要：分别采用三(氯异丙基)磷酸酯(TCPP)、膨胀石墨(EG)和阻燃聚合物聚醚多元醇(POP)三种阻燃剂制备聚氨酯自结皮泡沫(ISF)塑料。探讨了TCPP,EG和POP对聚氨酯ISF塑料的力学性能和阻燃性能的影响。结果表明:以POP为阻燃剂制备的聚氨酯ISF塑料,力学性能较好,工艺稳定性及综合性能优于其他两种阻燃剂制备的聚氨酯ISF塑料。当POP与聚醚EP-330N的质量比为70∶30时,制品的拉伸强度为17MPa,伸长率为125%,压陷硬度为76.5 shao A,氧指数为25%。因此,POP可广泛应用于聚氨酯ISF塑料。Polyurethane integral skin foams （ISF） were synthesized using flame retardants TCPP, EG, or POP respectively. The effect of three flame retardants on mechanical property and flame resistance of polyurethane ISF were investigated. The results show that the oxygen index of polyurethane ISF using POP as flame retardant is 25 %, the mechanical property of polyurethane ISF is also good, the process stability and combination property are better than that using the other two flame retardants. As a flame retardant, POP is widely used in polyurethane ISF.
