摘　　要：水性油墨是目前最具发展潜力的环保型油墨,其中最重要的成分是水性树脂连接料,其在很大程度上决定了水性油墨的优劣。水性聚氨酯(WPU)作为一种水分散型环保材料,具有低挥发性有机物(VOCs)含量、安全不易燃、结构可设计性强等优点,但在耐水性、耐溶剂性、黏附力、稳定性、力学性能和机械性能上欠佳,需要对其进行改性以满足作为喷墨油墨连接料的应用需求。该文首先简述了喷墨打印方式和WPU性能的影响因素;然后,重点综述了WPU改性方法的研究进展,主要对二醇/二胺扩链改性、有机氟/有机硅改性、丙烯酸酯改性、环氧树脂改性、纳米材料改性、生物质材料改性、超支化改性、点击化学改性和封端改性等的技术特点、优势和不足、WPU性能提升和适用范围进行了论述;最后,从复合改性、生物基原料、功能化和高固低黏4个方面对WPU喷墨油墨连接料未来的发展趋势进行了展望。Water-based ink is currently the most development potential of environmentally friendly ink,with water-based resin linker being the most important component,which to a large extent determines the advantages and disadvantages of water-based ink.Waterborne polyurethane(WPU),a water-dispersed environmentally friendly material,has the advantages of low volatile organic compounds(VOCs)content,safety and non-flammability,as well as strong structural designability,etc,and disadvantages of poor water resistance,solvent resistance,adhesion,stability,and mechanical properties.Therefore,modification is needed in order to meet the application requirements of inkjet ink bonders.In this review,the inkjet printing mode and the influencing factors on WPU performance were briefly described.The research progress on WPU modification methods was specifically discussed,with the technical characteristics,advantages and advantages,as well as WPU performance improvements and scope of application of diol/diamine chain expansion modification,organofluorine/silicone modification,acrylate modification,epoxy modification,nano-materials modification,biomass material modification,hyperbranched modification,click chemistry modification and end-capping modification introduced.Finally,the future development trend of WPU inkjet ink binders were prospected from the four aspects of composite modification,biomass raw materials,functionalization and low solid as well as high viscosity.
