目的 将 1,2-丙二醇与一种表面活性剂复配，把复配体系添加到润版液中，替代酒精实现免酒精润版。 方法 根据 HLB 值法，在众多表面活性剂中初步筛选出 3 种表面活性剂（椰子油脂肪酸二乙醇酰胺、烷醇酰胺、十二烷基硫酸钠），通过对单一表面活性剂润湿性能的研究发现，十二烷基硫酸钠适合与 1,2-丙二醇进行复配，通过研究复配体系的润湿性能，得出二者最佳配比和添加量，以获得润版液最佳配方。 结果 1,2-丙二醇和十二烷基硫酸钠复配体系最佳质量比为 1.5︰0.005，复配体系此时的临界胶束质量分数为 1.505%，配制的润版液各项性能指标均符合要求。 结论 1,2-丙二醇和十二烷基硫酸钠复配，可实现免酒精润版，解决了酒精在润版时带来的危害。

This work aimed to prepare a compound system using a surfactant and 1, 2-propanediol to replace alcohol and add it into fountain solution to get alcohol-free fountain solution. First, preliminary screening based on the HLB value of surfactants resulted in three kinds of surfactants (Coconut oil fatty acid diethanolamide, alkanolamide, sodium dodecyl sulfate). Based on the research of the wettability of single surfactant systems, sodium dodecyl sulfate was found to be suitable for complexing with 1,2-propanediol. Through research on the wettability of compound systems, the best mix ratios and addition amounts were obtained, in order to get the optimal formula of fountain solution. The best mass ratio between 1,2-propanediol and sodium dodecyl sulfate was found to be 1.5︰0.005, and the critical micelle concentration of the compound system under this condition was 1.505%. All performance indexes of the prepared fountain solution met corresponding requirements. Compounding 1,2-propanediol and sodium dodecyl sulfate could create alcohol-free fountain solution, which avoids the damage generated by alcohol during fountain.
