摘　　要：PU树脂制备过程中,在不加任何助剂的前提下有些树脂表现为清澈透明,但有些树脂则出现泛蓝光的现象。虽然无论清澈透明或者泛蓝光的PU树脂对于合成革的物性没有产生影响,但此现象一直困扰着PU生产与研究者。本文通过以不同固含量的PU树脂为起点,研究其对泛蓝光现象的影响。实验结果显示,当PU树脂固含量高于40%时容易出现泛蓝光现象,同时对蓝光产生的原因做出了相应的解释。During the preparation of PU resin,some resins appear clear and transparent without adding any additives,but some resins show a phenomenon of blue light.Although the PU resin,whether it is clear,transparent or bluish,has no effect on the physical properties of synthetic leather,this phenomenon has always troubled PU production and researchers.In this paper,the impact of the pan-blue phenomenon was studied by using PU resins with different solid contents as a starting point.The experimental results showed that when the solid content of PU resin was higher than 40%,the phenomenon of pan-blue light was prone to occur,and the reason for the blue light was explained accordingly.
