摘　　要：目的研究不同分散剂种类、研磨时间、储存时间条件对制备出的UV喷墨色浆分散稳定性能影响。方法通过不同分散剂(685,CH-13,及685与CH-13的混合物(m685∶mCH-13=1∶1))制备色浆,预分散后改变研磨时间(60,75,90 min)、储存时间(2,12,20 d)得出9组色浆试样,根据测量粒径大小和粒径分布情况进行分析。结果分散剂685分散效果好,研磨时间为75 min,储存时间为2 d下色浆分散稳定效果好。结论分散剂685制备的色浆的分散稳定性最佳,研磨时间为75 min最佳,色浆稳定性与储存时间呈现负相关关系。The aim of this work was to study the effects of different kinds of dispersants, grinding time and storage time on the dispersion stability of UV inkjet colorants. Nine colorants samples were prepared by using different dispersants（685,CH-13,the mixture of 685 and CH-13）, predispersing, and changing grinding time（60, 75, 90 min） as well as storage time（2, 12, 20 d）. The particle size and particle distribution were measured and analyzed. The dispersion result of dispersant685 was good, and good dispersion stability was obtained when the grinding time was 75 min and the storage time was 2 d.The UV inkjet colorants made of dispersant 685 had the best dispersion stability, and the optimal grinding time was 75 min.The colorant stability and storage time showed a negative correlation.
