摘要:
为提高发泡聚氨酯材料的界面粘接性能，利用二乙醇胺与环氧树脂反应合成端羟基环氧树脂，再将其涂敷于发泡模具的内表面，加入聚氨酯羟基组分并与稍过量的异氰酸酯组分混合均匀后发泡成型，制得环氧树脂改性聚氨酯泡沫材料.研究了合成反应的温度、时间、配比以及反应动力学方程.红外光谱分析结果显示产物的环氧基特征吸收峰消失，且羟基特征吸收峰增强变宽，说明环氧基参与了反应并生成了端羟基环氧树脂.性能测试实验的结果表明：环氧树脂改性聚氨酯具有凝胶、固化快等特点，环氧树脂链段的引入可以将聚氨酯发泡材料的界面粘接强度提高约57%.
Abstract:
To improve surface adhesive properties of polyurethane foam, diethanolamine (DEA) was utilized to react with epoxy groups of epoxy resin to synthesize modified epoxy resin with terminal hydroxyl. Before foaming, epoxy resin with terminal hydroxyl had been coated on internal surface of a foaming mould. Hydroxyl components and isocyanine components of polyurethane were added into the mould and then the mixture foamed molding. Research emphases were placed on optimum reaction conditions including temperature, time, reactant proportions as well as kinetic analysis. Infrared characterizations illustrate that the absorption peak of epoxy group disappears, while the peak of hydroxyl group prominently strengthens and widens, which corroborates that the ringopening reaction takes place indeed. Besides results of property tests confirm that the polyurethane modified by epoxy resin can gel and cure in a shorter period than that of traditional polyurethane foam. Furthermore, tensile and shear strength tests verify that the introduction of epoxy resin improves the adhesive performance of modified polyurethane by around 57%.
