中文摘要：

以聚酯二元醇（PE-600）及聚醚二元醇（PEG-600）为原料，采用扩链法制备了具有光固化性能聚氨酯油墨保护树脂，并对其结构进行红外光谱分析表征，结果表明制备的产物与目标产物相符合．分析了原料的配比及引发剂的种类对于膜性能的影响．利用正交试验得出以PEG-600与PE-600的摩尔比为2：1、TDI与IPDI的摩尔比为1：1合成的氨酯油墨保护树脂配制成成膜树脂，光引发剂为Irgacure184，固化后热转印到ABS基材上，树脂膜表现为：与油墨的附着力强，耐磨耐溶剂，透明度好，高硬度（大于1H）．

英文摘要：

With polyester glycol and polyether glycol as materials, UV-curable polyurethane, used as ink protection resin, was synthesized by using the extender chain method. The structure of the UV-curable polyurethane was characterized by infrared spectrum. The results of the orthogonal design experiment show that when the molar ratio of PE-600/PEG-600 and TDI/IPDI is 1 ： 2 and 1 ： 1 respectively, and the UV initiator is Irgacure184, the heat of the UV-cured film is transferred to ABS base, and that the UV-cured film shows good performance such as good adhesion, wear and solvent resistance, high hardness （ 〉 1 H） and transparence.
