摘要 分析了反应原料及其用量对水性聚氨酯乳液性能的影响,综述了水性聚氨酯胶粘剂研究进展及其在包装领域的应用,指出初始异氰酸基(NCO)与羟基(OH)摩尔比为3.5,总量的异氰酸基(NCO)与羟基(OH)摩尔比在1.2~1.8之间,中和剂三乙胺(TEA)与二羟甲基丙酸(DMPA)的摩尔比为(0.73~0.78): 1,有机锡类催化剂用量在0.1%~0.2%之间,DMPA含量在3%~8%之间,水性聚氨酯乳液性具有较优异的性能. The effects of reactants and their amounts on the properties of the waterborne polyurethane emulsion were analyzed. The progress and application of waterborne polyurethane in packaging were summarized. When the original mol ratios of isocyanic acid group(NCO) to hydroxyl group (OH) were about 3.5, the total mol ratios of NCO to OH were between 1.2 and 1.8, the mol ratios of neutralization agent triethylamine (TEA) to dimethylol propionic acid(DMPA) were (0.73~0.78)∶ 1, the amounts of organotin catalyst were between 0.1% and 0.2%, the DMPA were between 3% and 8%, waterborne polyurethane emulsion has better properties.
