功能性水性聚氨酯的研究进展

Research Progress of Functional Waterborne Polyurethane

水性聚氨酯具有绿色、环保的特点,广泛应用于涂料、胶黏剂和表面整理剂等领域,但存在着力学性能低、热稳定性差的缺点。基于此,综述了近几年用于提升水性聚氨酯力学性能和热稳定性的方法,并就水性聚氨酯的应用领域进行了介绍,旨在为科研人员开发、合成新型水性聚氨酯提供帮助。

Waterborne polyurethane has the characteristics of green and environmental protection,and is widely used in coatings,adhesives and finishing agents,but there are shortcomings of low mechanical prop⁃erties and poor thermal stability.Based on this,the methods used to improve the mechanical properties and thermal stability of waterborne polyurethane in recent years are introduced,and the application field of wa⁃terborne polyurethane is introduced,aiming to help researchers develop and synthesize new waterborne polyurethane.
