Embodiment 1

[0027] Preparation method of high temperature direct injection dispersion water-based ink, including the following steps:

[0028] The first step: orthosilicate, anhydrous ethanol, and deionized water were mixed, and then the pH to 8 was adjusted with hydrochloric acid, and at a temperature of 50 ° C, it was reacted at a temperature of 8 h, and after the reaction was completed, the KH570 was added dropwise. Then reaction at a temperature 50 ° C, i.e., the modified nano silica solution is obtained; in the n-butanol as a solvent, the aqueous acrylic resin is mixed with the modified nanosoxiloxide solution, under temperature 90 ° C. The reaction is 5 h to obtain a modified aqueous acrylic resin;

[0029] Step 2: Mix the modified aqueous acrylic resin with antibacterial agents, and dispersed for 15 min under temperature 60 ° C, obtaining a liquid; then, deionized water, ethanol, and modified dispersant is added to the A liquid. It was mixed for 1 h to give a B liquid; then the aqueous...

Abstract

The invention discloses a preparation method of high-temperature direct-injection dispersed water-based ink, and the method comprises the following steps: mixing modified water-based acrylic resin with an antibacterial agent to obtain a solution A; sequentially adding deionized water, ethyl alcohol and a modified dispersing agent into the solution A to be mixed for 1-2 h, and obtaining a solution B; adding a water-based organic pigment into the solution B, adding a defoaming agent, and grinding through a three-roller grinder to obtain a solution C; sequentially adding deionized water, ethyl alcohol, water-based wax emulsion and a water-based flatting agent into the solution C, performing stirring and mixing at the rotating speed of 2,000 r/min, adding organic amine to adjust the pH to be 8-9, performing grinding through a three-roller grinding machine, and obtaining the water-based ink. The water-based ink has good stability, high temperature resistance and corrosion resistance, and due to the addition of the antibacterial agent, the water-based ink has good antibacterial performance; meanwhile, the water-based organic pigment and the auxiliaries can be uniformly dispersed through the modified dispersing agent.

Description

Technical field [0001] The present invention belongs to the field of water-based ink, and is, for example, a method for preparing high temperature direct injection dispersion water-based ink. Background technique [0002] Comparative Document CN102993823B discloses a printing plate for water-based ink, which specifically relates to high resolution water-based inks for inkjet printing direct plate and its preparation method thereof. The present invention is based on the total amount of water-based ink, and 5-40% by weight of polymer, 0.01-10% by weight, from 0.01 to 10% by weight of the dye or pigment, 1-30% by weight of the organic solvent, The 0-5 wt% of the defoamer and the remaining amount of deionized water was stirred at room temperature. After the polymer was completely dissolved, the mixed solution was filtered, the resulting filtrate is the water-based ink of the present invention. The ink is sprayed on the surface of the metal substrate by inkjet printing machine (the me...
