Abstract

The invention relates to an alcohol-free environment-friendly fountain solution and a preparation method thereof. The fountain solution comprises, by weight, 70-85 parts of deionized water, 2-5 parts of pH modifiers, 10-25 parts of water-based colloid and 0.5-2 parts of nonionic surfactants. The preparation method includes the following steps that part of the deionized water is added into a stirred tank, the water-based colloid is added while the deionized water is stirred, stirring is continued until the water-based colloid is completely dissolved, and a colloid solution is obtained; the nonionic surfactants are added into the colloid solution, the nonionic surfactants and the colloid solution are fully stirred and mixed, and a mixed solution is obtained; and the pH modifiers are added into the remaining deionized water, the pH modifiers and the deionized water are stirred and mixed evenly and then added into the mixed solution, the mixture is fully stirred and dispersed, and the alcohol-free environment-friendly fountain solution is obtained. Compared with the prior art, the fountain solution is stable in property, safe, environmentally friendly, free of alcohol and good in printing adaptability; the added nonionic surfactants can effectively adjust the surface tension of the fountain solution, the preparation process is simple, the controllability is good, and the fountain solution is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of offset printing, and relates to an alcohol-free environment-friendly dampening solution and a preparation method thereof. Background technique [0002] Offset printing uses the two natural laws of immiscibility of oil and water and selective adsorption of solids to liquids, and builds the copied graphics and blank parts on the surface of the unified printing plate after technical treatment, so that the blank part has Strong water absorption performance, the graphic part is lipophilic and water repellent. In the printing process, water is supplied to the entire printing plate first, so that the blank part of the layout absorbs water to form a water film, and then ink is supplied to the printing plate. At this time, since there is a layer of water film in the blank part of the printing plate, the ink cannot be adsorbed on the blank part, and the graphic part is water-repellent and lipophilic and absorbs a ...
