摘    要:采用一种新方法来提高环氧封端聚氨酯固化速率和室温以上拉伸剪切强度.先以二甘醇胺和环氧氯丙烷为原料,氢氧化钠溶液作为催化剂合成了二缩水甘油二甘醇胺(DGDGA),并用FT-IR,MS对其结构进行了表征.再以自制的DGDGA对异氰酸酯封端的聚氨酯预聚体进行封端,合成了具有高反应活性的缩水甘油胺型聚氨酯(GAPU),用FT-...

关 键 词:二缩水甘油二甘醇胺  缩水甘油胺型封端聚氨酯  缩水甘油氨基甲酸酯  深冷胶黏剂

Abstract:A novel method was developed for the preparation of polyurethane with improved room-temperature curing rate and enhanced tensile shear strength at higher temperatures.Diglycidyl diglycolamine(DGDGA) was prepared through the reaction of epichlorohydrin and ethanolamine with the catalysis of sodium hydroxide aqueous solution.The structure of DGDGA was characterized by FI-IR,MS.DGDGA was used to convert the isocyanate terminated polyurethane prepolymer to glycidylamine terminated polyurethane(GAPU) with high r...
Keywords:Diglycidyl diglycolamine  glycidylamine terminated polyurethane  glycidyl carbamate  cryogenic adhesives
