[0027] A kind of preparation technology of environment-friendly water-based printing ink, comprises the steps:
[0028] The first step, according to the following parts by weight: 60-70 parts of polyacrylate emulsion, 6-7 parts of modified filler, 4-5 parts of pigment, 0.5-0.7 part of wetting agent, 0.8-1 part of dispersant, defoamer 0.5-0.7 parts, 10-12 parts of deionized water, weigh raw materials;
[0029] Specifically, the wetting agent is wetting agent 101A, Dalian Institute of Light Industry; the dispersing agent is polyethylene glycol; the defoaming agent is a silicone defoaming agent;
[0030] The second step, the preparation of color paste:
[0031]Add deionized water to the dispersing tank, then add the pigment, and ultrasonicate at room temperature for 10 minutes to prepare a water dispersion of the pigment, then add a wetting agent and half of the dispersant, disperse in a high-speed disperser at 6000r / min for 60 minutes, and then Put it into a sand mill and grin...
