[0036]
[0037]
[0038] The preparation method of the described water-based ink of embodiment 1~3, concrete process step is as follows:
[0039] a. Preparation of color paste: Weigh each component of the following formula, mix them evenly, and put them into a disperser for dispersion;
[0040]
[0041] B, grinding: the mixture obtained in step a is dropped into a sand mill filled with pure zirconia for grinding;
[0042] c. Ink adjustment: add self-crosslinking styrene-acrylic emulsion, wetting and leveling agent, defoamer, transfer aid to the mixture obtained in step b and disperse evenly after mixing, adjust the viscosity with non-ionic polyurethane thickener, Add a pH regulator to adjust the pH value.
[0043] In the above steps, the dispersion speed of step a is 1500r / min, and the dispersion time is 30-50min; in step b, grind twice at a grinding speed of 100kg / h u...
