摘　　要：本文比较全面地介绍了影响水性聚氨酯膜断裂伸长率的主要因素和提高方法,结合笔者所在实验室的研究工作,讨论了提高水性聚氨酯皮革涂饰剂膜断裂伸长率的方法,展望了具有高断裂伸长率的水性聚氨酯皮革涂饰剂的研究与应用前景。The main factors influencing the elongation at break of the aqueous polyurethane film and the modifying methods of aqueous polyurethane are introduced in detail in the paper. With the studies in this aspect done in our laboratory being considered, the ways that may be taken to increase the elongation at break of the aqueous polyurethane film are discussed, and the foreground in studies and application of aqueous polyurethane finishing agents with great elongation at break is prospected .
