| 目的 针对生产油墨所用的卧式封闭砂磨机，研究油墨生产工艺条件，以生产出质量良好的纯水型凹印油墨。方法 考察预分散工艺条件对油墨分散性的影响，确定所使用的高速叶轮分散机的转速与分散时间；研究基墨的颜基比、进料速度、研磨次数对油墨质量的影响，确定生产油墨的研磨条件；探讨提高水性油墨干燥速度的干燥剂的添加工艺。结果 研究结果表明，当预分散转速为1500 r/min，时间为30 min，颜基比为1∶1.25，进料速度的隔膜泵工作气压为0.2 MPa，并经过4遍研磨的油墨，其性能较好；干燥剂应先分散到丙烯酸乳液中，1000 r/min的转速下研磨60 min制成乳液，再添加至油墨中，即可提高油墨的干燥速度，又不影响油墨的其他性能。结论 采用文中的工艺条件生产的纯水型凹印油墨具有良好的分散性和印刷适性，印刷质量优良。 |

| The work aims to research the production process conditions of ink regarding the horizontal closed sand mill used to produce ink, so as to produce the water-based gravure ink of good quality. The effects of pre-dispersion process conditions on the ink dispersion were investigated to determine the revolving speed and dispersion time of the high-speed impeller dispersing machine; the effects of binder ratio, feeding speed and grinding times of base ink on the ink quality were studied to determine the grinding conditions of ink. The adding process of drying agent for improving the drying speed of water-based ink was discussed. The results showed that the water-based gravure ink had a good performance when the pre-dispersion speed was 1500 r/min, the dispersion time was 30 min, the binder ratio was 1∶1.25, the working pressure of diaphragm pump for controlling feeding speed was 0.2 MPa and the ink was ground for four times. The drying agent should be first pre-dispersed in polyacrylic emulsion and then ground into emulsion for 60 min at the speed of 1000 r/min. With the emulsion above added to the ink, it would not affect other performances of the ink while improving its drying speed. The water-based gravure ink produced with the above-mentioned process conditions has good dispersion and printability and excellent printing quality. |
