Problems solved by technology

However, due to the strong wettability of white cardboard, the surface coating of the paper is different from the surface film layer of other composite papers, which has a strong barrier effect on the penetration of water, and absorbs the water in the ink and volatilizes slowly. When the ink loses water too quickly during printing, it is easy to cause poor film-forming effect of the ink layer, low adhesion and easy to fall off
In view of the above characteristics, it is difficult for white cardboard to adapt to the printing requirements of gravure water-based ink, and it is impossible to achieve a satisfactory printing effect

Embodiment 1

[0037] 【formula】

[0038]

[0039] The water-based acrylic film-forming emulsion (purchased from DSM Coating Resin Co., Ltd.) has characteristics: a polymer emulsion of water-based acrylic acid with a pH value of about 7.5, a solid content of 48%, a Tg value of about 21°C, and an acid value of 50 mgKOH / g , Ultra-low VOC content.

[0040] The water-based acrylic non-film-forming emulsion (purchased from DSM Coating Resin Co., Ltd.) has characteristics: a styrene with a pH value of about 7.5, a solid content of 45%, a Tg value of about 100°C, and an acid value of 80 mgKOH / g And acrylic polymer emulsion, ultra-low voc content.

[0041] Described styrene-acrylic resin aqueous solution is prepared by following method:

[0042] Add 35% styrene-acrylic solid resin and 65% deionized water into the reactor, heat up to 55°C, and add the pH regulator diethanolamine while stirring, so that the pH value of the solution in the reactor is always maintained at About 8.5 (the consumption...

Abstract

The invention discloses gravure water-based ink for an ivory board and a printing method, and belongs to the field of water-based ink production. The ink is prepared by mixing water-based acrylic film-forming emulsion, water-based acrylic non-film-forming emulsion, a styrene-acrylic resin aqueous solution, organic pigments, polyethylene wax, a wetting dispersant, a levelling agent, a PH value regulating agent, a defoaming agent and water and has the advantages of being good in stability and the like. In the printing process, ultraviolet irradiation is performed in a matched mode, therefore, the performance indexes of a printed product on the aspects such as the glossiness and the levelling property are all obviously improved, and the very good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of water-based ink, in particular to a gravure water-based ink for white cardboard and a printing method. Background technique [0002] White cardboard is a thicker, firmer white cardboard made of pure high-quality wood pulp. It is widely used in the field of cigarette packaging because of its high color purity, good folding resistance, and good ink absorption. However, due to the strong wettability of white cardboard, the surface coating of the paper is different from the surface film layer of other composite papers, which has a strong barrier effect on the penetration of water, and absorbs the water in the ink and volatilizes slowly. If the ink loses water too quickly during printing, it will easily lead to poor film-forming effect of the ink layer, low adhesion and easy to fall off. In view of the above characteristics, it is difficult for white cardboard to adapt to the printing requirements of gravure ...
