摘　　要：介绍了阳离子水性聚氨酯的发展概况,包括阳离子水性聚氨酯的优点,目前存在的主要缺点,合成机理、合成方法及合成原料。简述了预聚物中R[n(—NCO)∶n(—OH)]值、亲水扩链剂的用量、中和剂的种类及中和度等因素对阳离子水性聚氨酯性能的影响。概述了阳离子水性聚氨酯的各种改性方法,包括环氧树脂改性、羟基硅烷改性、丙烯酸酯改性、纳米粒子改性等。介绍了阳离子水性聚氨酯在皮革涂饰剂、胶粘剂、织物整理剂等方面的应用概况,并对其发展方向作了展望。This article has described the development of cationic waterborne polyurethane in aspects of advantages, disadvantages, mechanism of synthesis, the methods of synthesis and the raw materials for syn- thesis. The influencing factors on properties of cationic waterborne polyurethane were summarized, including the R [ n （--NC0） ： n （--0H） 1 value of prepolymer, the content of hydrophilic chain extender, neutralizer and neutralization degree. Various modification methods for cationic waterborne polyurethane were also intro- duced,including modification with epoxy resin, hydroxy - terminated silane, polyacrylate and nano - parti- cle. The applications of cationic waterborne polyurethane in coating of leather, adhesive and coating of textile were given, and the development trend of the cationic waterborne polyurethane was described.
