摘　　要：探讨了水与多元醇的质量比对阻燃高回弹聚氨酯泡沫塑料的反应活性、泡孔结构及制品性能的影响。结果表明:随着水与多元醇的质量比增大,制品的乳白、到顶和上升时间均呈下降趋势,泡孔孔径逐渐变小,制品的玻璃化转变温度上升,制品的拉伸强度逐渐上升,断裂伸长率逐渐降低,制品的氧指数从25.0%降低到22.5%。The effect of mass ratio of water to polyols on reaction activity, cellular structure and mechanical properties of flame-retardant high resilience polyurethane（FRHRPU） are discussed. The results show that with the increase of mass ratio of water to polyols, the cream, reach-top and rise time of the product all decrease, the diameter of bubble holes becomes smaller, the ten- sile strength of the product rises gradually, elongation at break reduces gradually, and the oxy- gen index of the product reduces from 25.0% to 22.5%.
