A high-stability aqueous dye ink containing lignin sulfonate and a preparation method thereof

ActiveCN121495399BGuaranteed complete reversibilityEnsure color stabilityInksSuspended particlesSulfonate
The application provides a high-stability lignosulfonate-containing aqueous dye inkjet ink and a preparation method thereof, and belongs to the technical field of inkjet inks; the application constructs a repairable dynamic network through synergistic action: anchor copolymer functionalizes the surfaces of particles such as mica by using dopamine units, and the main units provide diol reaction sites; the bridging copolymer connects the particles into a three-dimensional structure by forming reversible borate ester chemical bonds with the diol sites through boronic acid groups; the synergistic action of the two suspends the particles through a gel structure during standing, and ensures long-term storage stability; during printing, the network collapses under shear force, and the viscosity sharply decreases to ensure smooth jet flow; after printing, the network self-repairs, and the viscosity is recovered to control droplet spreading, and finally, the unity of high stability and high printing performance is achieved.
