摘　　要：以甲苯二异氰酸酯(TDI)、聚丙二醇(PPG1000)、2,2-二羟甲基丙酸(DMPA)、单硬脂酸甘油酯(GMS)、酸性红B为主要原料,经自乳化法合成了一种稳定性良好的红色聚氨酯皮革染料。通过傅里叶红外光谱验证了产品结构;通过紫外-可见光谱验证了染料的色调未因结构的改变而发生变化;热失重分析得出染料的起始分解温度为320.9℃。产品单独成膜以及和皮革涂饰材料混合成膜后,膜的颜色干湿擦牢度均为5级。A stable red polyurethane high molecular leather dye was synthesized based on toluene-2,4-diisocyanate（ TDI）,poly propylene glycol（ PPG1000）,2,2-bis（ hydroxymethyl） propionic acid（ DMPA）,glyceryl monostearate（ GMS） and acid red B via a self emulsification method. The structure of the resulting dye was confirmed by Fourier transform infrared spectroscopy（ FTIR）. The UV-vis spectra analysis showed dye color did not change due to changes in the structure of the dye. The thermo-gravimetric analysis revealed that the initial decomposition temperature of the obtained dye was320. 9 ℃. The properties of the films formed by the dye alone or mixing with leather finishing agents were investigated,and the results demonstrated that the wet and dry friction color fastness of the films reached 5 level.
