Embodiment 1

[0025] In this embodiment, an anti-corrosion and anti-mold dampening solution compounded with κ-carrageenan-konjac gum comprises the following components and contents in parts by weight: 80 parts of deionized water, 12 parts of κ-carrageenan, 8 parts of konjac gum, 4 parts of tea polyphenols, 3 parts of ancient oil, 2 parts of sorbitol, 4 parts of pH regulator, 2 parts of antiseptic and fungicide, 2 parts of tributyl phosphate, 2 parts of alkylphenol polyoxyethylene ether;

[0026] The antiseptic and bactericide is a mixture of benzalkonium chloride, potassium sorbate, lauryl glucoside and isothiazolone.

[0027] Wherein the resistivity of deionized water at 25° C. is 1018 mΩ•cm; the pH adjuster is prepared by mixing phosphoric acid and ammonium dihydrogen phosphate, and the mass ratio of phosphoric acid and ammonium dihydrogen phosphate is 2:1.

[0028] Specific steps are as follows:

[0029] (1) Preparation of κ-carrageenan-konjac gum-tea polyphenol microspheres:

[0030] ...

Abstract

The invention discloses a corrosion-resistant mildew-proof fountain solution containing compounded k-carrageenan-konjak gum. The fountain solution is composed of the following raw materials in parts by weight: 70-85 parts of deionized water, 10-15 parts of k-carrageenan, 6-10 parts of konjak gum, 3-6 parts of tea polyphenol, 2-5 parts of Turkey red oil, 1-3 parts of sorbitol, 3-6 parts of a pH adjustor, 1-3 parts of a corrosion-resistant bactericide, 1-3 parts of tributyl phosphate and 1-3 parts of alkylphenol polyoxyethylene. The fountain solution, by compounding the k-carrageenan and the konjak gum, is taken as a hydrophilic film-forming agent, and improves the durability of a water film, so that the fountain solution disclosed by the invention has good wetting and permeating properties if being used.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to an anti-corrosion and anti-mildew dampening solution compounded with κ-carrageenan-konjac gum and a preparation method thereof. Background technique [0002] Offset printing uses the two natural laws of immiscibility of oil and water and selective adsorption of solids to liquids, and builds the copied graphics and blank parts on the surface of the unified printing plate after technical treatment, so that the blank part has 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 layout 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 adsorbed on the blank part, and t...
