| 摘 要： | 用新型难燃接枝聚合物聚醚多元醇和聚醚多元醇3050的混合物与甲苯二异氰酸酯(TDI)自由发泡反应，制备了阻燃型聚氨酯软质泡沫。讨论了难燃接枝聚合物聚醚多元醇的用量对聚氨酯软质泡沫密度、氧指数和力学性能的影响。结果表明，随着难燃聚醚用量的增加，聚氨酯软质泡沫的阻燃性能提高，力学性能也有显著提高，泡沫体的密度降低。

| Abstract: | The flame retardant flexible polyurethane foams (FPUF)was prepared from TDI and the mixture of new flame retardant graft polymer polyether polyols(FRGPPP) and polyether polyols 3050 by free foaming method. The effects of FRGPPP content on density, oxygen index and mechanical properties of FPUF were investigated. The results show that with the increasing of FRGPPP content, the fire resistance improved and the mechanical properties increased remarkably, the density of FPUF decreased. |
