Problems solved by technology

[0004] The ink can be ejected normally on the printer and requires a specific viscosity, and usually, a high-viscosity solvent has a slow drying speed, so it provides a good control of the viscosity-temperature curve, drying speed and printing response frequency. Balanced water-based ink has become an urgent technical problem in this technical field

Abstract

The invention relates to water-based ink and a preparation method thereof, and belongs to the field of digital ink-jet printing. The ink is prepared from 1-10 wt% of Polyglykol P41 / 12000, 0-5 wt% of dye, 5-40 wt% of humectant, 1-10 wt% of viscosity modifier, 0.05-5 wt% of auxiliaries and the balance water. By adding a proper amount of Polyglykol P41 / 12000, the amount of other solvent low in drying speed is reduced, and therefore the drying speed of ink on a medium is increased, a reasonable viscosity-temperature curve is adjusted, and the ink can have a quite good response frequency on a printing machine.

Description

technical field [0001] The invention relates to an aqueous ink and a preparation method thereof, in particular to an aqueous ink that can adjust the viscosity and printing response frequency of the aqueous inkjet ink and a preparation method thereof, which is beneficial to improve the drying speed of the ink on the medium, and belongs to digital inkjet print field. Background technique [0002] In the field of digital inkjet printing, water-based inks have had a large market in China in recent years, mainly used for indoor advertising. A large content of water-based ink formulations is water. In addition, there are alcohols, ethers, surfactants, pH adjusters, bactericides, etc. to adjust the ink viscosity, surface tension, pH and other parameters to meet the requirements of the printer. [0003] Solvents with low boiling points are volatile, and solvents with high boiling points can penetrate deep into the dielectric coating. More and more new nozzle technology, faster and...
