Embodiment 1

[0019] Embodiment 1: Preparation of fountain solution

[0020] An alcohol-free fountain solution prepared from the following components by weight (kg): water-soluble lanolin 6, sulfobutyl ether cyclodextrin 6, glucose 3, galactose 2, raffinose 2, cetearin Alcohol 3, gallic acid 2, tea saponin 1, white mineral oil 2, caprylic / capric triglyceride 2, sodium nitrate 2, methylisothiazolinone 0.5, additive 8, water 40;

[0021] 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 until completely dissolved.

[0022] Its prep...

Embodiment 2

[0026] Embodiment 2: Fountain solution performance test

[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.

[0028] Determination of ink emulsification rate C: by weight method.

[0029] 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 alcohol-free fountain solution. The alcohol-free fountain solution is characterized by comprising the following raw materials of, by weight, 2-8 parts of water-soluble wool fat, 2-8 parts of sulfobutyl ether-beta-cyclodextrin, 1-4 parts of glucose, 1-3 parts of galactose, 1-3 parts of melitose, 1-4 parts of cetostearyl alcohol, 1-3 parts of gallic acid, 0.5-1.5 parts of tea saponin, 1-3 parts of white mineral oil, 1-4 parts of caprylic / capric triglyceride, 1-3 parts of sodium nitrate, 0.2-1 part of methylisothiazolinone, 5-10 parts of auxiliaries and 30-50 parts of water. The alcohol-free fountain solution is simple in technology, avoids use of alcohol, is gentle and harmless to human bodies and the environment, reduces cost, and meets the requirements for energy conservation and environmental protection; the raw materials of the alcohol-free fountain solution are easy to obtain.

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. At present, fountain solution contains a large amount of ethanol or isopropanol, which volatilizes in a large amount in the printing workshop and affects the health of workers; at the same time, its emissions have adverse effects on the environment, so reducing the use of alcohol is an inevitable trend. Contents of the invention [0003] The purpose of the present invention is to provide a kind of alcohol-free fountain solution. [0004] The present invention is achieved through the following technical solut...
