摘　　要：采用磷酸三苯酯(TPP)和可膨胀石墨(EG)进行复配,通过一步法发泡工艺制备了具有阻燃性能的软质聚氨酯泡沫(FPUF)。通过极限氧指数(LOI)、垂直燃烧和烟密度测试对FPUF的阻燃性能进行研究,探索了TPP与EG之间的协同阻燃作用。结果表明:TPP与EG之间存在一定的协同增强FPUF的阻燃性能。当TPP/EG配比为1/3、复配型阻燃剂用量为30份时,阻燃FPUF的LOI值达到25%。同时,复配型阻燃剂添加到FPUF中还能降低有焰燃烧时间,并起到一定的抑烟作用。The triphenyl phosphate （TPP） and expand graphite （EG） were selected to form one new kind of compound flame retardants, and the flexible polyurethane foam （FPUF） with excellent flame retardant was prepared with one-step foaming process method. The flame retardant effect of FPUF was researched through limiting oxyer index （LOI）, vertical burning test and smoke density measurement. The synergy flame retardant effect between TPP and EG was discussed. The result show that the flame retardant properties of the FPUF improve because of the synergistic flame retardancy between TPP and EG. The LOI value of FPUF can reach to 25% when the ratio of TPP and EG is 1/3 and the content of TPPIEG is 30 phr. At the same time, the compound type flame retardant added to the FPUF can reduce the flame burning time and has the smoke suppression effect.
