Embodiment 1

[0018] Embodiment 1: Preparation of fountain solution

[0019] An environment-friendly dampening solution prepared from the following components by weight (kg): isooctyl alcohol polyoxyethylene ether phosphate 8, corn starch 6, ammonium bicarbonate 2, trishydroxymethylaminomethane 1, smoke Amide 2, sodium octyl sulfonate 2, castor oil 2, castor oil maleate 6, tea polyphenol 1, lactic acid 4, aspartame 3, tea tree essential oil 1.5, additive 8, water 40;

[0020] Among them, 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 and stir at 200rpm unti...

Embodiment 2

[0025] Embodiment 2: Fountain solution performance test

[0026] 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.

[0027] Determination of ink emulsification rate C: by weight method.

[0028] Dilute the dampening solution described in Example 1 to 3% with distilled water, add 50 g of black ink and 50 g of the diluted dampening solution to the container at one time, stir at 100 r / min for 1 hour and then let it stand for 10 minutes, remove the unabsorbed dampening solution The liquid and the ink are separated in layers, and the emulsification rate of the ink is calculated according to the following formula:

Abstract

The invention discloses an environment-friendly fountain solution, which is characterized by being prepared from the following ingredients in parts by weight: 2 to 10 parts of polyoxyethylene isooctyl ether phosphate, 2 to 8 parts of corn starch, 1 to 3 parts of ammonium bicarbonate, 0.5 to 1.5 parts of trihydroxymethyl aminomethane, 1 to 3 parts of nicotinamid, 1 to 3 parts of sodium octane sulfonate, 1 to 3 parts of castor oil, 2 to 8 parts of castor oil maleic acid ester, 0.5 to 1.5 parts of tea polyphenol, 1 to 5 parts of lactic acid, 1 to 4 parts of L-Aspartyl-L-phenylalanine methyl ester, 1 to 2 parts of tea tree essential oil, 5 to 10 parts of auxiliaries and 30 to 50 parts of water. The fountain solution disclosed by the invention has the advantages that the raw material resource is rich, the cost is low, the wetting effect is good, volatile and irritant substances are not contained, the cost is reduced, the fountain solution is mild and harmless to human bodies and environments, and the requirements of energy saving and environment protection are met.

Description

technical field [0001] The invention relates to a printing fountain solution, in particular to an environment-friendly 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. Fountain solution is composed of various components, among which isopropyl alcohol (IPA) is the most commonly used additive in fountain solution, and its main function is to emulsify ink. IPA is a flammable organic solvent with low boiling point and high volatility, which is harmful to the human body, and its emissions will pollute the environment. Therefore, the use of IPA is harmful to the environment, human body, printing equipment and product quality. It is an inevitable trend to reduce the frequen...
