目的 制备一种适用于胶版印刷机的环保型水基油墨清洗剂。方法 以吐温-80、十二烷基二甲基甜菜碱为表面活性剂，碳酸钠为碱性助剂复配达到清洗目的，去离子水和乙醇为溶剂，三乙醇胺为抗再沉积剂，苯并三氮唑为缓蚀剂，尿素为增溶剂，氯化钠为电解质，研究环保型油墨清洗剂的合成条件。通过单因素变量法对影响产品性能的各种因素进行考察。结果 得到了最终优化的配方，水为70 g，乙醇为15 g，十二烷基二甲基甜菜碱为6 g，吐温-80为12 g，碳酸钠为3 g，尿素为2 g，苯并三氮唑为1 g，三乙醇胺为1 g，氯化钠、消泡剂适量。在此条件下合成的产品为透明、无沉淀、无分层液体，净洗力为99.8%。结论 产品综合性能良好，适用于胶版印刷机的油墨清洗。

The work aims to prepare an environment friendly water-based ink cleaner suitable for offset printing press. Tween 80 and dodecyl dimethyl betaine were used as surfactants and sodium carbonate as an alkaline auxiliary to achieve cleaning effect, and deionized water and alcohol were used as solvent, triethanolamine as anti-redeposition, benzo Triazole as rust inhibitor, urea as solubilizer and sodium chloride as electrolyte to study the synthesis conditions of environment friendly ink cleaner. The factors affecting the product properties were investigated by univariate variable method. The optimal formula was obtained: 70 g water, 15 g alcohol, 6 g dodecyl dimethyl betaine, 12 g Tween 80, 3 g sodium carbonate, 2 g urea, 1 g benzo Triazole, 1 g triethanolamine, appropriate amount of sodium chloride and defoamer. The product which was synthesized under this condition was transparent and clarified with cleaning rate of 99.8%. The comprehensive performance of the product is good and the product is suitable for cleaning the ink of the offset printing machine.
