Embodiment 1

[0025] In this embodiment, a high-performance dampening solution containing kappa-carrageenan-konjac gum compound comprises the following components and contents in parts by weight: 80 parts of deionized water, 12 parts of kappa-carrageenan, 8 parts of konjac gum, tea 4 parts of polyphenols, 3 parts of ancient oil, 2 parts of sorbitol, 4 parts of pH regulator, 2 parts of allyl alcohol polyoxyalkyl ether, 4 parts of water film regulator, 2 parts of fatty alcohol polyoxyalkyl ether;

[0026] The water film regulator is composed of glycerin and white granulated sugar, and the weight ratio of the two is 3:1.

[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 high-performance fountain solution containing a k-carrageenan-konjac gum compound. The fountain solution comprises 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 pH conditioning agent, 1-2 parts of allyl alcohol polyoxy alkyl ether, 3-5 parts of water film regulator, and 1-3 parts of fatty alcohol polyoxy alkyl ether. According to the fountain solution, through the k-carrageenan-konjac gum compound acting as a hydrophilic film-forming agent, the durability of a water film is improved, and the fountain solution has good wettability and permeability when in use.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to a high-performance fountain solution containing kappa-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 the graphic part a...
