| 摘要: |
| 目的 通过不同的预分散转速、预分散时间、氧化锆珠与油墨的配比和研磨时间来研究对水性柔印油墨分散性的影响。方法 通过激光粒度仪来检测油墨中95%的颗粒粒径及其分布，以此来判断最佳的预分散工艺条件，以及工艺参数对油墨分散性能的影响。结果 当预分散转速为2000 r/min，预分散时间为40 min，氧化锆珠与油墨的质量比为2︰1，研磨时间为2 h时，油墨中95%的颗粒粒径最小且其分布范围最窄，具有最佳的分散性。结论 预分散转速、预分散时间、氧化锆珠与油墨的配比及研磨时间对水性油墨的分散性均具有较大的影响。 |

| Abstract: |
| The work aims to study the influence of dispersion process on water-based flexo ink dispersivity through different pre-dispersion rotating speeds, pre-dispersing time, and the ratio and milling time between zirconia balls and the printing ink. Laser partied size instrument was employed to evaluate the conditions for dispersion process and the influence of technological parameters on the dispersibility of ink through measuring 95% particle size and distribution of ink. When pre-dispersion rotating speed was 2000 r/min, pre-dispersing time 40 min, mass ratio 2︰1, and milling time 2 h, 95% particle of ink had the smallest size, the most narrow distribution and the best dispersion. In conclusion, the pre-dispersion rotating speeds, the pre-dispersing time and the ratio and milling time between zirconia balls and the printing ink have great influence on the property of the water-based flexo ink. |
