Problems solved by technology

The phosphorus contained in the traditional fountain solution will lead to the deterioration of the metal in the key parts of the equipment. At the same time, the discharge of phosphorus-containing sewage into the water body will cause eutrophication of the water body and cause the deterioration of water quality, thus threatening the natural environment.

Embodiment 1

[0018] Embodiment 1: Preparation of fountain solution

[0019] A phosphorus-free fountain solution prepared from the following components by weight (kg): hydroxyethyl-β-cyclodextrin 4, cetearyl glucoside 3, triolein 3, pine Oleyl Alcohol 1.5, Menthone 2, Tartaric Acid 0.8, Imidazolidinyl Urea 2, Sodium Lauryl Amphoacetate 2, Sodium Xylene Sulfonate 1.5, Benzalkonium Chloride 0.6, Span 60 0.8, Additive 8, Water 40;

[0020] Among them, the auxiliary agent is made of the following raw materials by weight (kg): glycerin 7, polyethylene glycol 6, glycine 1, citric acid 2, oleic acid 1.5, clove oil 0.5, rhamnose 0.5, tea polyphenol 0.5, carbonic acid Sodium hydrogen 2, sodium citrate 18, Tween 80 3, water 40; first dissolve citric acid and sodium citrate in water, heat to 50-60°C, then add glycerin, polyethylene glycol, clove oil, oleic acid and sodium bicarbonate, stirred for 15 minutes, cooled to room temperature, added the rest of the raw materials, stirred until completely dis...

Embodiment 2

[0025] Embodiment 2: Determination of ink emulsification rate

[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 a non-phosphorus fountain solution which is characterized by comprising, by weight, 2-6 parts of 2-hydroxyethyl-beta-cyclodextrin, 1-4 parts of cetearyl glucoside, 1-4 parts of glycerol trioleate, 1-2 parts of terpineol, 1-3 parts of menthone, 0.5-1 part of tartaric acid, 1-3 parts of imidazolidinyl urea, 1-3 parts of sodium lauroamphoacetate, 1-2 parts of sodium xylene sulfonate, 0.5-1 part of benzalkonium chloride, 0.2-1 part of span 60, 5-10 parts of addition agents and 30-50 parts of water. The fountain solution contains no phosphorus, can effectively avoid the adverse effect of phosphorus containing materials on a device, is favorable for device maintenance and reduces cost; deterioration of water quality caused by phosphorus containing emissions is avoided, and the environmental protection requirements are met.

Description

technical field [0001] The invention relates to a printing fountain solution, in particular to a non-phosphorus 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, which can not only generate inorganic salts stably, continuously replenish the worn hydrophilic layer on the blank part of the plate, but also clean the oil on the plate and reduce the temperature of the plate, so that the image and text on the printing plate The ink and the water in the blank part remain relatively balanced and stable to achieve the expected printing effect. The phosphorus contained in the traditional fountain solution will lead to the det...
