Embodiment 1

[0025] In this embodiment, an insect-proof dampening solution containing κ-carrageenan-konjac gum compound 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, tea poly 4 parts of phenol, 3 parts of Swire oil, 2 parts of sorbitol, 4 parts of pH regulator, 2 parts of fatty alcohol polyoxyethylene ether, 2 parts of polyether modified silicon defoamer, 3 parts of pest control additive;

[0026] The pest control additive is prepared by mixing the following components by weight: 0.5 parts of wormwood powder, 0.5 parts of inulin, 0.5 parts of rosemary powder and 1.5 parts of polyethylene glycol.

[0027] The resistivity of deionized water at 25°C is 10 18 mΩ·cm; 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.

[0028] Specific steps are as follows:

Abstract

The invention discloses an insect-preventing fountain solution containing a kappa-carrageenan-amorophophallus konjac compound. The insect-preventing fountain solution comprises the following raw materials in part by weight: 70-85 parts of deionized water, 10-15 parts of kappa-carrageenan, 6-10 parts of amorophophallus konjac, 3-6 parts of tea polyphenol, 2-5 parts of sulfated caster oil, 1-3 parts of sorbitol, 3-6 parts of a pH regulator, 1-3 parts of fatty alcohol-polyoxyethylene ether, 1-3 parts of a polyether modified silicone defoamer, and 2-4 parts of an insect-preventing additive. Kappa-carrageenan and amorophophallus konjac are compounded to form a compound, and the compound as a hydrophilic film former improves the water film persistence, so that the fountain solution has high wettability and permeability when used; kappa-carrageenan- amorophophallus konjac-tea polyphenol microspheres slow release of tea polyphenol during the using process of the fountain solution, so that the oxidation resistance of tea polyphenol is improved greatly, and the using stability of the fountain solution is ensured; and besides, the fountain solution can achieve the effect of insect prevention, printed image-text is clear, the color is restored, the requirement of printing production is met, and the produced fountain solution is fragrant and pleasant in smell, environment-friendly, nontoxic, and harmless to the human body.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to an insect-proof fountain solution containing kappa-carrageenan-konjac gum compound 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 ...
