Embodiment 1

[0020] Put the raw material desiccant, water-based resin, ethanol, wetting agent, thickener, dispersant, defoamer, pigment, film-forming aid and water into the mixer according to the formula shown in Table 1, and use it at 2500rpm The mixer is stirred for 2-4 hours, and then the quick-drying water-based ink composition is obtained by using a bead mill with 0.1 mm zirconia beads for 6 hours of grinding and dispersion treatment at a speed of 1500 r / min. (According to Table 1, when the raw material does not contain desiccant, obtain the common type water-based ink composition as comparative example.)

Abstract

The invention relates to a water-based ink composition and a preparation method thereof. The water-based ink composition is composed of: 2-10% of a drying agent, 20-50% of water-based resin, 5-15% ofethanol, 1-5% of a wetting agent, 2-10% of a thickening agent, 1-5% of a dispersing agent, 1-5% of a defoaming agent, 2-10% of pigment, 2-10% of a film-forming assistant and 20-40% of water. Specifically, the drying agent is selected from any one or a mixture of two or more of 2-hydroxy-N, N-dimethyl acetamide, 3-hydroxy-N, N-dimethyl propionamide, N, N-dimethyl acetamide, N, N-diethyl acetamide,dimethyl carbonate, diethyl carbonate and ethyl methyl carbonate. The raw materials are mixed uniformly according to the mass ratio and are then ground till uniform dispersion, thus obtaining the water-based ink composition. The water-based ink composition can change the drying performance of water-based ink, and greatly increase the intaglio printing speed up to 115m/min.

Description

technical field [0001] The invention belongs to the field of water-based ink, and in particular relates to a water-based ink composition capable of changing the drying performance of the water-based ink, a preparation method and an application thereof. Background technique [0002] Oil-based inks contain organic solvents, which cause pollution to the ambient air during the printing and drying process. Solving the pollution problem of oil-based ink is an urgent technical problem to be solved. Among them, replacing the organic solvent in the oil-based ink with water as a solvent is the main way to solve the problem of organic solvent pollution. However, after the solvent is replaced with water, the boiling point of the ink is relatively high due to the formation of hydrogen bonds between water molecules, which slows down the drying speed of printing and affects the printing efficiency. Drying speed has become one of the biggest technical obstacles to ink water-based. Althou...
