[0038] The preparation method of the low-voltage heating ink specifically comprises the following steps:
[0039] (1) Weigh the components of the low-voltage heating ink in parts by mass, put the water-based acrylic resin, rosin resin, pH regulator and deionized water in a stirring tank and stir for 5 to 10 minutes. After mixing evenly, add Carbon black, graphite, carbon nanotube dispersion and xanthan gum, stir evenly, finally add dispersant and defoamer, stir evenly to form primary heating ink;
[0040] (2) After mixing the primary heating ink and ball milling beads according to the mass ratio of 3:1, put it in an electric mixer and stir for 1 to 3 hours, then take it out and filter it, and finally put the primary heating ink in a sand mill and grind it until the particle size is below 5 μm , Obtain low voltage heating ink.
[0041] In the preparation process of the low-voltage heating ink, xanthan gum can form a stable three-dimensional network structure with conductive fi...
