| 摘 要： | 采用4,4′-二苯甲烷二异氰酸酯(MDI)和端羟基染料合成了有色聚氨酯,通过红外光谱表征了其分子结构。利用这种有色聚氨酯作为高分子染料对聚氨酯树脂进行着色,研究了有色聚氨酯及其着色后聚氨酯的色牢度、耐溶剂性能、热机械性能。结果表明:有色聚氨酯及其着色的聚氨酯树脂具有优异的色牢度,干湿摩擦色牢度均达到5级;有色聚氨酯的耐溶剂性能与聚氨酯树脂相同,在水及甲苯中无溶解掉色现象;有色聚氨酯的玻璃化转变温度与聚氨酯树脂接近,可以作为一种性能优异的高分子染料用于聚氨酯着色。

| Abstract: | Colored polyurethane has been synthesized by reaction of 4 ,4'-methylene diphenyl diisocyanate (MDI) with the hydroxy-terminated dye Reactint Black. The molecular structure of the colored polyurethane was characterized by FT-IR spectroscopy. This colored polyurethane was used as a polymeric dye to color polyurethane resin and the color fastness,solvent resistance,and thermal-mechanical properties of the resulting colored polyurethane resin and the colored polyurethane itself were studied. The results showed... |
