摘要
水性聚氨酯是聚氨酯溶于水形成的聚氨酯体系,在介绍其性能及分类的基础上,综述了水性聚氨酯的物理共混改性,特别是重点讨论了化学改性研究中的有机硅改性、丙烯酸酯改性、环氧树脂改性、有机氟改性以及纳米粒子改性等改性方法。随着改性技术的进步,环保型水性聚氨酯的新功能将不断呈现,环保型可降解的生物基聚氨酯材料将是今后的主要研究方向之一。
Waterborne polyurethane is a polyurethane system which is soluble in water. In this paper, the physical properties and classification of waterborne polyurethane were introduced. The modification of silicone, acrylate, epoxy resin, modification of epoxy resin, modification of nano particles and modification of nano particles were discussed. With the development of the modified technology, the new function of environmental protection type water-based polyurethane will be presented, and it is pointed out that the environmental protection-based polyurethane material is one of the main research directions in the future.
