辐照水性聚氨酯的复合改性研究与应用进展

摘要

Irradiated waterborne polyurethane mainly included gamma-irradiation rays (Co-60 ) irradiated WPU and ultraviolet (UV) curing WPU, and several multi-modified methods were summarized for radiation waterborne polyurethane. Weather resistance and mechanical properties of radiation waterborne polyurethane were superior to those of waterborne polyurethane, so radiation waterborne polyurethane could be used in the field of printing adhesive, floor paint, wood coating, automotive top coats. In the end, the development prospects of radiation water-borne polyurethane were expected.%综述了辐照水性聚氨酯(WPU)最常用的多元改性方法,重点介绍了γ射线(Co-60)辐照WPU和紫外光(UV)固化WPU的改性方法.改性后的辐照WPU的耐候性和机械性能要远优于WPU,辐照WPU经改性后可应用于印花粘合剂、地板涂料、木器漆涂料和汽车漆膜等领域.最后展望了辐照WPU的发展前景.
