Abstract
This invention relates to a screen printing water ink and its making method. The water ink comprises high-performance water-base PU, pigment and adjuvant, and it is made through water-base PU preparation and printing ink confect. At first select proper components, components' proportions, and optimize synthesizing condition to compose high-performance water-base PU. Then use 70-87wt% water-base PU, 12-18wt% pigment, 0-0.8wt% dispersant, 0-0.5wt% antifoamer, 0.1-1wt% thickening agent, 0-6wt% arbitration agent to mix fully to make water ink. The printing water ink has strong adhesiveness, bright color, good printing adaptation, and is suitable for PVC base-material surface printing and adhering. It is used for the making of magcard, bank card and credit card.
