摘要
简述了硬段含离子的水性聚氨酯乳液及软段含离子的水性聚氨酯乳液的差异及优缺点,重点介绍了羧酸盐型、磺酸盐型和季铵盐型3类软段含离子的水性聚氨酯乳液的制备、性能以及国内外研究进展,介绍了其应用领域和国内外应用情况,并对软段含离子的水性聚氨酯的发展及应用前景进行了展望。
This paper reviewed the differences between aqueous polyurethane（APU） with ions in soft segment and APU with ions in hard segment, including their advantages and disadvantages. The synthesis, characters and study progress in the world of APU with carboxyl, sulphonate or quaternary ammonium salt as ions were discussed. The application fields was introduced, and the development and prospect of APU with ions in soft segment were discussed.
