摘　　要：选择脂肪族异氰酸酯为主要原料，制备了一种耐光型水性聚氨酯皮革涂饰剂。讨论了影响产品耐黄变性能的主要因素。探讨了芳香族和脂肪族两种类型的水性聚氨酯黄变和耐黄变机理。表４，图１。Abstract A lightfast aq. polyurethane emulsion for leather finishing was prepared mainly from aliphatic isocyanate. Main factors affecting the lightstability of the product were also discussed in the paper. Yellowing and yellowing resistance mechanism of the two aq. dispersions made from aromatic or alipbatic polyurethane were researched.
