Abstract

The invention discloses a low-alcohol efficient fountain solution and a preparation method thereof. The fountain solution is prepared from the following raw materials of gelatin, potassium citrate, sodium bicarbonate, graphene oxide, sodium chloride, sodium succinate, diacetone-D-mannitol, octyl dodecyl glucoside, alcohol alkoxylate, polyoxyethylene silicon alcohol ether, rhamnolipid, borax, tartaric acid, magnesium acetate, aluminium potassium sulfate, sodium dodecyl benzene sulfonate, hydroxymethyl cellulose, twain-60, polyethylene glycol, n-butyl alcohol and soft water. The fountain solution prepared through the preparation method is then diluted into a working solution with the concentration being 3%, the pH value is 5.1-5.3, the surface tension is 42.5-46.2 mN / m, the electric conductivity is 912-978 us / cm, and the performance parameter requirements for the fountain solution are met. Meanwhile, the fountain solution is low in alcohol, good in surface tension and capable of obtaining a good printing effect and meets the application requirements of the printing industry.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a low-alcohol and high-efficiency fountain solution and a preparation method 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 to act on the blank part of the printing plate to make the blank part The role of the agent absorbs water to form a layer of water film, which avoids the blank part of the printing plate from being infiltrated and polluted by printing ink during the printing process, prevents dirty plates, and at the same time can obtain better printing quality and printing effect. [0003] Fountain solution has successively experienced the development of ordinary type fountain solution, alcohol type fountain solution and nonionic surfactant fountain solution. Ordinary type f...
