Embodiment 1
[0052] 39.2 parts of deionized water, 14 parts of polyethylene glycol PEG400, 6 parts of polyethylene glycol PEG300, 2 parts of fatty alcohol polyoxyethylene ether phosphate MOA-3P, 0.3 parts of polyether modified siloxane Twin 4200, 0.2 parts Add 1,2-benzisothiazolinone and 1.5 parts of triethanolamine into a stirring tank with paddle stirring, stir evenly at a low speed, add 0.8 parts of alkali swelling thickener TT-615 and 1.0 parts of Alkali-swellable thickener DR-180, as the molecular chain of the thickener gradually opens, the viscosity of the system increases, and the stirring speed is gradually increased. When the system is evenly mixed, continue to add 35 parts of carbon black with a mass concentration of 20% under stirring Water-based pigment paste until all materials are mixed evenly and the stirring is over.
[0053] The ink mixture prepared above was filtered through two stages of 1000 mesh and 1 micron to obtain a filtrate, which was then subjected to vacuum defo...
