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] Wherein the auxiliary agent is made of the raw materials of the following 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 compr...

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, which is characterized in that it is composed of the following raw materials in parts by weight: propylene glycol alginate 2-10, epoxy butyl stearate 1-5, glycine 1-3, arginine Acid 1‑3, Sodium Lauryl Sulfate 1‑8, Hydroxyethyl Urea 1‑5, Hydrogen Peroxide 0.5‑1, Tannin 1‑3, Vanillin 1‑2, Sodium EDTA1‑3 , silicone defoamer 0.2‑1, additives 5‑10, water 30‑50. The fountain solution of the invention does not need to add IPA or other alcohol additives during use, which not only reduces the cost, but also is gentle and harmless to the human body and the environment, and meets the requirements of energy saving, environmental protection and safety.

Description

technical field [0001] The invention relates to a 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 printing machines. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of ink on the graphic and text to the blank part and prevent dirty plates. Isopropyl alcohol (IPA) is the most commonly used additive in fountain solutions, and its main function is to emulsify the 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 discharge also pollutes the environment. Therefore, the use of IPA is harmful to the environment, human body, printing equipment and product quality. It is an inevitable t...
