Embodiment 1

[0025] In this embodiment, a high-resistance water-based fountain solution containing κ-carrageenan-konjac gum compound comprises the following components and contents by weight: 80 parts of water, 12 parts of kappa-carrageenan, 8 parts of konjac gum, tea 4 parts of polyphenols, 3 parts of Taikoo oil, 2 parts of sorbitol, 4 parts of pH adjuster, 2 parts of fatty alcohol polyoxyethylene ether, 2 parts of defoamer, and 2 parts of compounding additives;

[0026] The compound auxiliary agent is a mixture of phosphatidylethanolamine, triethanolamine, citric acid, sodium citrate, olive oil and vitamin E.

[0027] The defoamer is a mixture of an organic silicon defoamer and a polyether-modified organic silicon defoamer, and the weight ratio of the two is 2:1.

[0028] The pH regulator is formed by mixing phosphoric acid and ammonium dihydrogen phosphate, and the mass ratio of phosphoric acid and ammonium dihydrogen phosphate is 2:1.

[0029] Specific steps are as follows:

Abstract

The invention discloses a high hard water resistance fountain solution with kappa-carrageenan-konjac glucomannan. The high hard water resistance fountain solution with kappa-carrageenan-konjac glucomannan comprises, by weight, 70-85 parts of water, 10-15 parts of kappa-carrageenan, 6-10 parts of konjac glucomannan, 3-6 parts of tea polyphenol, 2-5 parts of turkey red oil, 1-3 parts of sorbitol, 3-6 parts of pH modifier, 1-3 parts of fatty alcohol-polyoxyethylene ether, 1-3 parts of defoaming agent, and 1-3 parts of compound additive. According to the high hard water resistance fountain solution with kappa-carrageenan-konjac glucomannan, the kappa-carrageenan is compounded with the konjac glucomannan, hydrophilic filmogen is obtained, durability of water films is improved, and good madefaction and permeability are achieved when the fountain solution is used; a kappa-carrageenan-konjac glucomannan-tea polyphenol microballoon has the characteristics that an average grain diameter is thin and the tea polyphenol releases slowly; the release of the tea polyphenol is delayed when the fountain solution is used , the inoxidizability of the tea polyphenol is greatly improved, and the using stability of the fountain solution is ensured; and in addition, the fountain solution has good hard water resistance, is applicable to running water coming from various sources, and has no corrosivity on equipment.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to a high-hardness-resistant water-based fountain solution containing kappa-carrageenan-konjac gum and a preparation method thereof. Background technique [0002] Offset printing is to use the two natural laws of immiscibility of oil and water and selective adsorption of solids to liquids. The copied graphics and blank parts are jointly established on the surface of the unified printing plate after technical treatment, so that the blank parts have Strong water absorption performance, the graphic part is lipophilic and water repellent. In the printing process, water is supplied to the entire printing plate first, so that the blank part of the printing plate absorbs water to form a water film, and then ink is supplied to the printing plate. At this time, since a layer of water film already exists in the blank part of the printing plate, the ink cannot be ads...
