摘　　要：通过合成新型聚醚多元醇 ,对交联剂和催化剂的选择等试验 ,有效地改善了HFC 2 45fa聚氨酯硬泡的粘接性能 ,满足了冰箱冰柜生产对聚氨酯硬泡粘接强度的要求。研制生产的HFC 2 45fa组合聚醚发泡特性及发泡制品的性能均达到了CFC— 11型同类产品水平。s The adhesive property of HFC 245fa rigid PU foam was improved by a new synthexized polyether polyols and the selection of crosslinking agent and catalyst,meeting the need for adhexive strength of refrigerator.The foaming property and product property of the prepared HFC 245fa premixed polyether foam had come up to the property level of CFC 11 foam of the same grade.
