Abstract

The invention discloses an environment-friendly high-stability printing fountain solution and a preparation process thereof. The foundation solution comprises the following components: xanthan gum, vitamin C, sodium succinate, propylene glycol alginate, mannitol, isomeric alcohol ethoxylates, hydroxyethyl carboxymethyl cellulose, ethylenediamine tetraacetic acid disodium, guanylic acid, polyoxyethylene lauryl ether, graphene oxide, acetic acid, disodium hydrogen phosphate, ammonium sulfate, L-lysine, sodium tripolyphosphate, polyvinyl alcohol, tween-40, ethylene glycol and soft water. The fountain solution is diluted to 4% in concentration to obtain a working solution, the pH value of which is ranged from 4.9 to 5.2, the surface tension of which is ranged from 46.5mN/m to 50.3mN/m and the conductivity of which is ranged from 1004us/cm to 1057us/cm. The ink balance and stability are excellent, the performance parameter requirement of the fountain solution is met and a good printing quality can be guaranteed, and meanwhile, the fountain solution is green and environment-friendly and satisfies the application demand of printing industry well.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an environment-friendly high-stability printing fountain solution and a preparation process thereof. Background technique [0002] Fountain solution is an essential and important chemical additive in the printing industry. It mainly uses the principle of oil-water immiscibility and the selective adsorption of solids to liquids. In the printing process, water is supplied to the entire printing plate first, so that the blank part absorbs water to form a layer of water film due to the action of the dampening agent, and then the ink is printed. Because the oil and water are not compatible, the ink cannot be absorbed on the blank part, and the graphic part Water-repellent and lipophilic to absorb a layer of ink, which not only prevents the blank part of the printing plate from being infiltrated and polluted by printing ink during the printing process, prevents dirty plate...
