Abstract: In order to discuss the effects that cosolvent takes on ink used in water-borne pen performance and quality, select and use ethanol, methanol, isopropanol, Ethylene glycol monobutyl ether, ethanediol and propanediol six common water-soluble cosolvent, using them to prepare the samples of ink used in Water-borne pen, testing the surface tension, viscosity, drying rate and adhesionforce. Select three kinds of cosolvent to carry the formula experiment. The results of the study show that: the ink prepared with different kinds csolvent have different performance. The ink prepared by isopropyl alcohol has good quality performance.

Abstract: Water-based ink in low-energy surface wetting more difficult and hinder its application. In order to solve water ink in low-energy on the surface wettability problem, change the kind of cosolvent, kind and content of surfactants prepared ink. They were tested in low-energy CD the surface contact Angle to examine wettability of ink, test the surface tension, ink affecting wettability factors were analyzed. Results show that: in water-based ink add isopropyl alcohol, flow ping agent 432 and substrate wetting agent 245, can better improve its surface wettability in low-energy, and base material wetting agent 245 content about 1.25% wet effect is good.
