摘　　要：综述了聚氨酯水分散体涂料和水性双组分聚氨酯涂料的合成、性能、应用、改性研究新进展 ,讨论了副反应对双组分水性聚氨酯涂料的涂膜形成、活化期及涂膜外观等的影响 ,指出了水性聚氨酯涂料的发展趋势。With the restrictions of environment reg ul ations on volatile organic compounds (VOC) in coatings, waterborne polyurethane paints, in which high performance combined with low VOC value, become developed trends of coatings technology. The synthesis, properties, applications and modif ied studied of aqueous polyurethane dispersion and two-component waterborne pol yurethane were viewed. The influence of side reactions on the film formation, po t life and film appearance of two-component waterborne polyurethane were discus sed. The trends of waterborne polyurethane were pointed out.
