Embodiment 1

[0019] Embodiment 1: Preparation of fountain solution

[0020] A corrosion and scale inhibiting dampening solution, prepared from the following components by weight (kg): sucrose ester 8, liquid paraffin 1.5, lauryl amidopropyl hydroxysultaine 6, alkyl diphenyl ether disulfone Sodium acid 5, alkyl dimethyl amine oxide 1, zinc sulfate 2, sulfaguanidine 1.5, polyaspartic acid 1, polyepoxysuccinic acid 1.5, isothiazolone 0.8, sodium lactate 1.5, additive 8, water 40 ;

[0021] 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 re...

Embodiment 2

[0026] Embodiment 2: the test of fountain solution performance

[0027] 1. Ink emulsification rate

[0028] 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.

[0029] Determination of ink emulsification rate C: by weight method.

[0030] 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 accordin...

Abstract

The invention discloses a corrosion and scale inhibition fountain solution. The corrosion and scale inhibition fountain solution is characterized by being composed of the following raw materials, by weight, 2-10 parts of sucrose ester, 1-2 parts of liquid paraffin, 2-8 parts of lauramidopropyl hydroxy sulfoBetaine, 1-6 parts of sodium lauryl diphenyl ether disulfonate, 0.5-1.5 parts of dodecyldimethylamine oxide, 1-3 parts of zinc sulfate, 1-2 parts of sulfaguanidine, 0.5-1.5 parts of polyaspartic acid, 1-2 parts of polyepoxysuccinic acid, 0.5-1 part of isothiazolinone, 1-2 parts of sodium lactate, 5-10 additives and 30-50 parts of water. The corrosion and scale inhibition fountain solution has good scale inhibition and corrosion protection effects, lowers maintenance cost of a printing system, is low in ink consumption amount and good in printing effect, and meets the requirements of environmental protection and energy saving.

Description

technical field [0001] The invention relates to a printing dampening solution, in particular to a corrosion and scale inhibiting dampening 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. During the printing process, due to the influence of water quality, insoluble and greasy calcium soap will be generated in the fountain solution, resulting in deposits on the surface of the printing plate and water roller, which will affect the transfer and spreading of ink and fountain solution. Severe contamination fault occurs. [0003] Polyaspartic acid and polyepoxysuccinic acid are water-soluble polymers, which have the characteristics of phosphorus-free, non-toxic, pollution-free and ...
