Abstract

The invention discloses a high-performance fountain solution and a preparation method thereof, and belongs to the technical field of printing. The high-performance fountain solution is prepared from the following raw materials of butyl acetate, sodium alginate, potassium carbonate, Turkey red oil, citric acid, triammonium citrate, simethicone, tallow amine, potassium phenylacetate, sodium dodecylbenzene sulfonate, saponin, a compound additive, pentaerythritol, water, polyacrylamide, phthalic acid and ammonium bisulfite. The high-performance fountain solution is prepared through the steps of raw material weighing, mixed reaction, filtering, defoaming, standing and the like. According to the high-performance fountain solution and the preparation method thereof, under the mutual cooperationof polyacrylamide, phthalic acid and ammonium bisulfite, and the pH value stability and water-ink balance of the fountain solution are synergistically improved, so that the performance of the fountainsolution is extremely high.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a high-performance fountain solution and a preparation method thereof. Background technique [0002] The offset printing process is mainly based on the principle of water-ink immiscibility, emulsification, wetting, and selective adsorption. The blank part is hydrophilic and ink-friendly, and the graphic part is lipophilic and water-repellent. has a very important role in closing. Therefore, the fountain solution should have five basic functions: First, during the printing process, the fountain solution will spread rapidly on the printing plate, forming a water film on the non-graphic part of the printing plate, and this water film can prevent the ink from flowing to the printing plate. The non-graphic part diffuses, and this layer of water film is thin and uniform. The second is that the fountain solution should maintain relative stability during printing, and the ...
