| 目的 为有效提升柔印薄膜水墨的印刷适性，对润湿剂W1、消泡剂D1以及增稠剂T1在柔版薄膜水墨制备过程中不同添加量产生的影响及其最佳值进行探究。方法 通过对柔印薄膜水墨粘度、细度、附着牢度及稳定性等性能测试，确定了润湿剂W1、消泡剂D1以及增稠剂T1的最佳用量。结果 随着润湿剂W1含量的增加，柔版水性油墨的润湿性先增加后减小，W1质量分数最适为0.6%~0.9%；加入增稠剂T1后，柔印水墨体系粘度明显增大；当T1的质量分数超过0.9%后，柔印水性油墨的粘度突增，且热稳定性差；当消泡剂D1的质量分数为0.4%时，可以达到很好的消泡及抑泡效果，且附着及热稳定性能优异。结论 柔印薄膜水墨中加入适量的润湿剂、消泡剂及增稠剂可以增加其印刷适性。 |

| The work aims to study the effect of the contents of wetting agent W1, defoamer D1 and thickener T1 on flexible printing ink on film to improve the printability of flexible printing ink effectively. The optimum amount of wetting agent W1, defoamer D1 and thickener T1 was determined by testing the performance the viscosity, fineness, adhesion fastness and stability of the waterborne ink. Wettability of waterborne ink increased firstly and then decreased with the increase of wetting agent W1 content. The optimum amount of W1 was 0.6% to 0.9%. Viscosity of waterborne ink signif-icantly increased with the increase of thickener T1 content. When the content of T1 exceeded 0.9%, the viscosity of the waterborne ink sharply increased and the thermal stability was destroyed. When the mass fraction of defoamer D1 was 0.4%, it showed excellent defoaming ability and good adhesion and thermostability. The printability of water-based flexible printing ink used on films can be improved by adjusting the appropriate content of wetting agent, defoamer and thickener. |
