| 摘 要： | 环状碳酸乙烯酯(EC)分别与乙二胺、己二胺开环反应合成1,2-乙二氨基甲酸羟乙酯(EDHU)与1,6-己二氨基甲酸羟乙酯(HDHU),用FT-IR、1H-NMR、13C-NMR等手段对其结构进行表征并作为扩链剂与二异氰酸酯(MDI)、聚酯多元醇反应制备聚氨酯热熔胶,对热熔胶的黏结性能、结晶性能、微相分离程度、表面张力及流变性能进行研究,结果表明:EDHU与HDHU作为扩链剂合成的聚氨酯热熔胶的微相分离程度分别为91.2%和83.9%,与传统的1,4-丁二醇(BDO)扩链剂合成的热熔胶相比,EDHU合成的热熔胶黏结强度提高了20%。

| Abstract: | 1,2-Ethyl dihydroxyethyl urethane ester(EDHU)and 1,6-hexa dihydroxyethyl urethane ester(HDHU) were synthesized by the reaction of ethylene carbonate(EC) with ethylene diamine and hexamethylene diamine respectively. Structures of EDHU and HDHU were characterized by FT-IR,1H-NMR and13C-NMR. They were used as chain extenders to react with diisocyanate(MDI)and polyester diols to get the polyurethane hot-melt adhesives.The adhesive,crystal,micro-phase separation,surface force and rheological properties were studied. The results showed that the micro-phase separation achieved to 91.2% and 83.9%, respectively, with EDHU and HDHU as chain extenders. Compared with the traditional polyurethane hot-melt adhesive extended by 1,4-butylene diol(BDO), the adhesive strength increased by 20% when extended by EDHU. |
