Embodiment 1

[0025] In this embodiment, a high-viscosity and low-surface-tension dampening solution containing κ-carrageenan 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, and tea polyphenols 4 parts, 3 parts of ancient oil, 2 parts of sorbitol, 4 parts of pH regulator, 2 parts of coconut oil fatty acid diethanolamide, 2 parts of fatty alcohol polyoxyethylene ether, 6 parts of glycerin.

[0026] 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.

[0027] Specific steps are as follows:

[0028] (1) Preparation of κ-carrageenan-konjac gum-tea polyphenol microspheres:

[0029] ①. Dissolve κ-carrageenan, konjac gum and tea polyphenols in deionized water as the water phase for later use;

[0030] ②. Measure Taik...

Abstract

The invention discloses a high-viscosity low-surface-tension fountain solution containing k-carrageenan. The high-viscosity low-surface-tension fountain solution containing k-carrageenan consists 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 konjac 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 regulator, 1-3 parts of cocoanut fatty acid diethanolamide, 1-3 parts of fatty alcohol-polyoxyethylene ether and 3-8 parts of glycerin. According to the fountain solution, k-carrageenan and konjac gum are compounded to serve as a hydrophilic film-forming agent to improve the durability of a water film, so that the fountain solution has favorable wettability and permeability.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to a high viscosity and low surface tension fountain solution containing κ-carrageenan 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 the graphic...
