摘　　要：采用全水发泡工艺,通过对配方的调节,研制了一种具有一定耐压强度和较好吸油性能的聚氨酯软质泡沫塑料。研究了催化剂配比及用量、泡沫稳定剂用量、粗MDI指数对聚氨酯软质泡沫吸油性能的影响。采用聚醚(N-220),当催化剂辛酸亚锡的质量份为0.20、催化剂A33的质量份为0.55、泡沫稳定剂有机硅油的质量份为1.0、粗MDI指数0.85左右、发泡剂去离子水的质量份为4～8时,所制备的聚氨酯泡沫泡孔结构和吸油效果较好。The flexible polyurethane foam that had certain compressive resistance and high oil absorption was prepared by water-blown formulation adjustment.The effect of major technology parameters,including the ratio and dosage of catalysts system,the dosage of stabilizing agent as well as the effect of crude MDI isocyanate index on the oil absorption property of flexible polyurethane foam was discussed.The result showed that the oil absorption effect of the foam was good when polyether polyols N-220 was used,with t...
