Embodiment 1

[0019] Embodiment 1: Preparation of fountain solution

[0020] An alcohol-free fountain solution prepared from the following components by weight (kg): propylene glycol alginate 7, epoxy butyl stearate 3, glycine 2, arginine 2, lauryl sulfate Sodium 6, hydroxyethyl urea 3, hydrogen peroxide 0.8, tannin 2, vanillin 1.5, sodium edetate 2, silicone defoamer 0.5, additive 8, water 40;

[0021] The auxiliary agent is made of the following raw materials by weight (kg): gum arabic 7, phosphatidylethanolamine 2, triethanolamine 3, sodium gluconate 6, Tween 20 4, citric acid 3, sodium citrate 10, olive oil 2, Vitamin E 0.3, water 50; under the condition of 70-80°C water bath, add gum arabic, phosphatidylethanolamine, triethanolamine, Tween 20 and olive oil to the water at 200rpm, stop the water bath after 1 hour, cool to room temperature and add The rest of the raw materials were stirred at 200rpm until they were completely dissolved.

[0022] Its preparation method comprises the fol...

Embodiment 2

[0026] Embodiment 2: the performance index of dampening solution

[0027] Fountain solution mainly affects the balance performance of water and ink in the printing process, and the emulsification rate of ink is an important parameter. The nature of the fountain solution has an important influence on the ink emulsification rate. According to the principle of offset printing, it is feasible for the ink emulsification rate to be lower than 26% during the offset printing process.

Abstract

The invention discloses an alcohol-free fountain solution. The alcohol-free fountain solution is characterized by consisting of following raw materials in parts by weight: 2-10 parts of alginic acid propylene glycol alginate, 1-5 parts of epoxy butyl stearate, 1-3 parts of glycine, 1-3 parts of arginine, 1-8 parts of sodium dodecyl sulfate, 1-5 parts of hydroxyethyl urea, 0.5-1 part of hydrogen peroxide, 1-3 parts of tannin, 1-2 parts of vanillin, 1-3 parts of EDTA (Ethylene Diamine Tetraacetic Acid), 0.2-1 part of organic silicon defoamer, 5-10 parts of additive and 30-50 parts of water. According to the alcohol-free fountain solution disclosed by the invention, IPA (Iso Propyle Alcohol) or other alcohol additives do not need to be added during a using process of the alcohol-free fountain solution, the cost is reduced, and the alcohol-free fountain solution is mild and harmless to a human body and environment and adapts to the requirements of energy conservation, environmental protection and safety.

Description

Technical field [0001] The invention relates to printing fountain solution, in particular to an alcohol-free fountain solution and a preparation method thereof. Background technique [0002] Fountain solution is an indispensable chemical additive in the printing process of color printers. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of the ink on the graphics and text into the blank part and prevent the dirty plate. Isopropyl alcohol (IPA) is the most commonly used additive in fountain solution. Its main function is to emulsify ink. IPA is a flammable organic solvent with low boiling point and high volatility, which affects the gloss of the ink and damages the rubber roller. What's more serious is that IPA is harmful to the human body, and the emissions will also pollute the environment. Therefore, the use of IPA is detrimental to the environment, the human body, printing equipment and product quality. It is an inevitable...
