| 摘要: |
| 目的 通过对水性油墨的印刷工艺进行条件优化，对比、分析不同工艺下的印刷品中溶剂残留的重复性和稳定性。方法 在相同的生产工序和生产批号下，从不同的生产车号中随机抽取平行样，采用顶空-气相色谱/质谱联用仪进行溶剂残留的测定。结果 乙醇和乙酸正丙酯的绝对偏差大于0.1 mg/m2，但其相对偏差小于10%，其他成分的绝对偏差均小于0.1 mg/m2，重复性较好；在相同分类、不同车号下，4类残留控制物的测定总量均远低于指标值，稳定性较好。结论 水性油墨既能满足环保印刷的要求，又能避免出现溶剂残留超标问题。 |

| Abstract: |
| The work aims to compare and analyze the repeatability and stability of solvent residuals in printed matters by optimizing the conditions for printing technology of water-based ink. Select parallel samples randomly from different production serial-numbers but same production process and production batch, then determine solvent residuals by headspace-gas chromatography/mass spectrometry (HS-GC/MS). While the absolute deviation of other components was less than 0.1 mg/m2, the absolute deviation of ethanol and n-propyl acetate was greater than 0.1 mg/m2, but their relative deviations was less than 10%, which demonstrated the satisfactory repeatability. Under the same classification and different car numbers, the total amount of the four kinds of solvent residuals was far below the index value, which illustrated the stability was good. Water-based ink can not only meet the requirements of environmental printing, but also avoid the problem of excessive solvent residuals. |
