AI Technical Summary

Problems solved by technology

Traditional inks cause paper jams due to excessive water content. If the water content decreases, the stability of the ink needs to be more scientific to ensure the overall formula. This is also the difficulty of water-based pigment inks for high-speed inkjet printers.
[0003] The printing speed of the current high-speed inkjet printing equipment is above 60 pages per minute. Since the traditional ink will make the paper wet and soft during printing, it will cause paper jams during high-speed printing. Pigment ink for printing equipment is imperative

Abstract

The invention relates to water-based pigment ink used for a high-speed ink-jet printer and a preparing method thereof. The water-based pigment ink includes 5-15 parts of pigment, 0.3-1 part of a defoamer, 1-3 parts of a dispersant, 39.6-67.6 parts of purified water and 26.1-38.4 parts of a waterborne solvent. The method includes (1) preparing the purified water; (2) adding the purified water, thepigment, the dispersant and the waterborne solvent according to a mass ratio into a dispersing machine, and dispersing the materials to obtain a mixture; (3) grinding the mixture until the particle size is less than 500 nm; and (4) adding the mixture into a stirrer, adding a pH adjusting agent, the defoamer, a humectant, an aseptic and a surfactant according to a ratio, and fully stirring the mixture to obtain the ink.

Description

technical field [0001] The invention belongs to the field of material science and engineering, and in particular relates to a water-based pigment ink for a high-speed inkjet printer and a manufacturing method thereof. Background technique [0002] With the increasing popularity of high-speed inkjet printers in recent years, dye inks and conventional water-based pigment inks are not suitable for high-speed inkjet printing equipment. Traditional inks cause paper jams due to excessive water content. If the water content decreases, the stability of the ink needs to be more scientific to ensure the overall formula. This is also the difficulty of water-based pigment inks for high-speed inkjet printers. [0003] The printing speed of the current high-speed inkjet printing equipment is above 60 pages per minute. Since the traditional ink will make the paper wet and soft during printing, it will cause paper jams during high-speed printing. Pigment inks for printing devices are imper...
