| 摘 要： | 以聚酯多元醇、甲苯二异氰酸酯和二羟甲基丙酸为主要原料,采用环氧树脂改性制备出稳定的水性聚氨酯油墨连结料。水性油墨连结料的红外光谱分析说明合成了水性聚氨酯结构油墨连结料;差示扫描量热法测试表明环氧树脂复合改性增加了涂膜交联度,涂膜玻璃化转变温度(Tg)明显提高;粒径分布分析说明经过环氧树脂改性水性聚氨酯树脂的粒径分布变宽;热失质量分析说明环氧树脂改性增加了涂膜的耐热性;水性聚氨酯油墨性能测试说明水性油墨连结料PUIV-1的基本性能优于所用的水性丙烯酸连结料。

| Abstract: | A series of stable waterborne polyurethane ink vehicles have been prepared from toluene diisocyanate,polyester polyols and dimethylolpropionic acid and epoxy as modification resin.FT-IR analysis of waterborne polyurethane ink vehicle showed that waterborne polyurethane ink vehicle was prepared.Differential scanning calorimetric measurements of films tests showed that the crosslink degree and Tg of the films here improved greatly when epoxy resin was added.Particle size distribution analysis showed that waterborne polyurethane ink vehicle modified by epoxy resin was broaden.TG analysis showed that heat resistance of the films improved much when epoxy resin as modification agent.The properties test of waterborne polyurethane ink vehicle showed that PUIV-1 was better than waterborne acrylic vehicle. |
