目的 研究6501与6502表面活性剂复配后添加到润版液中替代酒精， 实现免酒精润版。方法使用润版粉配制标准润版液， 加入不同质量分数的6501与6502， 测试单一体系的临界胶束浓度； 根据复配原理， 将6501与6502复配， 得出二者最佳配比和添加浓度， 获得润版液的最佳配方。结果 6501和6502复配体系最佳质量比为4.36： 5.54， 复配体系此时的临界胶束浓度为0.1%， 配制的润版液各项性能指标均符合要求。结论 表面活性剂6501和6502复配实现免酒精润版是可行的， 解决了酒精在润版时带来的危害。

This paper studied a combination of surfactants 6501 and 6502 which was added to fountain solution to replace alcohol so as to get an alcohol-free fountain solution. First, the original solution was prepared with fountain powder, then different concentrations of surfactants 6501 and 6502 were added to test the critical micelle concentration of the single system. According to the compounding principle and method, surfactants 6501 and 6502 were mixed and the best mix ratio and the optimum adding concentration were obtained, thus, a best formula fountain solution were gained. The best ratio was 4.36 : 5.54 for compound 6501 and 6502, and the critical micelle concentration was 0.1% at this ratio. Each performance parameter of this formula can meet requirements. Combination of surfactants 6501 and 6502 to replace alcohol is feasible to make alcohol-free fountain solution which solves the problem that alcohol causes hazards during dampening.
