摘　　要：研究了环保型发泡剂种类、特殊催化剂对建筑保温用聚氨酯泡体结构与性能的影响。研究结果表明,可通过改变催化剂有机锡用量协调凝胶速率与发泡速率的匹配以调节泡体结构及性能;不同类型的发泡剂所制得的聚氨酯泡体结构及性能均有所不同。The effects of the kind of green-foaming agent and the special catalyst on the structure and property of polyurethane foam for the building thermal insulation had been studied in this thesis. Research results showed that the match between the gelatinizing rate and the foaming rate would be adjusted by specific catalyst, and then the structure and property of polyurethane foam could be controlled in this way. The results also indicated that the kind of foaming agent could affect the structure and property of polyurethane foam.
