A method for preparing a nanosilver-containing antimicrobial ink is provided to produce the antibacterial ink having sterilizing or antibacterial functions without deteriorating the quality of ink. A method for preparing a nanosilver-containing antimicrobial ink includes the steps of: (1) preparing acrylic resins having a solid content of 50wt% by synthesizing an acrylic resin containing MMA monomer as a main material in polyglycol monoethyl ether acetate at 140 °C for about 6-7 hours; (2) mixing 60-70% of the prepared acrylic resin with 3-5wt% of a dispersant; and (3) adding 20-30% of pigment or aluminum paste, pearl powder, etc, 3-5% of an antifoaming agent and a leveling agent, and 1-2% of an anti-discoloring agent to the dispersant-dispersed acrylic resin, and dispersing the admixture at high speed. To impart an antibacterial property and adhesion to the prepared ink, a nanosilver solution having a nanosilver size of 1-5 nm and a nanosilver concentration of 10% is added to the ink in a ratio of 0.3% and mixed in an agitator. |
