摘　　要：以聚醚多元醇（PPO330）和甲苯二异氰酸酯（TDI）为原料,合成了一种泡孔结构较好的聚氨酯软质泡沫材料,研究了催化剂和匀泡剂质量分数对其孔结构的影响。结果表明,随着胺催化剂AN33质量分数的增大,泡沫孔径和开孔率都随之增大。而随着锡催化剂二丁基二月桂酸锡质量分数增大,泡沫的孔径和开孔率随之变小。匀泡剂L-580质量分数在1.0%~1.5%之间时,泡沫孔径最大,随L-580质量分数增加,泡沫开孔率先增加后减小,在其质量分数为1.0%时,开孔率最大。Using polyether polyol（ PPO330） and toluene diisocyanate（ TDI）,the flexible polyurethane with certain compressive resistance was prepared. The effect of catalysis and stabilizing agent on cellular structure of flexible polyurethane foam was discussed. The result shows that increasing the dosage of AN33,its pore size and opening ratio are increased; the pore size and opening ratio are decreased when increasing the dosage of dibutyltindilaurate. When the mass fraction of L-580 is between 1. 0% to 1. 5%,the pore size reaches the maximum. When the dosage of L-580 is increased,its opening ratio first increases and then decreases,the opening ratio is the largest when the mass fraction of L-580 is 1. 0%.
