Problems solved by technology

Although the staff have made a lot of technical attempts, such as changing the resin, adjusting the vitrification of the resin, etc., the effect is not very satisfactory
For water-based systems, especially gravure printing systems, the slow drying speed will affect the printing efficiency, which is a great obstacle to the use of water-based inks. Therefore, it is difficult for water-based inks to achieve the printing efficiency of oil-based inks, especially under high humidity conditions. Printing, the drying speed of the printed matter surface will be greatly reduced, which greatly affects the printing speed

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...
