摘　　要：较全面地介绍了PU光老化的原理,抗紫外光老化测试和表征方法,以及利用有机抗老化助剂和无机纳米材料提高PU抗老化性能的研究进展。提出了加大对PU光老化的机理性研究、开发更加有效的有机抗老化助剂和实现无机纳米材料改性PU工业化利用的研究方向。The principle of PU degradation, testing and characterization methods were comprehensively introduced. The current researches of improving the ageing resistance of PU modified by organic anti - aging agents and inorganic nano materials were also reviewed. Finally, some suggestions and prospect were given to the research in this area. Deep study on UV aging mechanism of PU, as well as development of more effective organic anti - aging agents and the realization of the industrial use for PU modified with inorganic nano material will be the trends.
