Embodiment 1

[0024] In this embodiment, a dampening solution containing κ-carrageenan prepared by high-energy small molecule water comprises the following components and contents in parts by weight: 80 parts of water, 12 parts of κ-carrageenan, 8 parts of konjac gum, tea polyphenols 4 parts, 3 parts of Swire oil, 2 parts of sorbitol, 4 parts of pH regulator, 2 parts of polyoxyethylene fatty acid ester, 2 parts of silicone defoamer.

[0025] Wherein said pH adjuster is formed by mixing phosphoric acid and ammonium dihydrogen phosphate, and the mass ratio of phosphoric acid and ammonium dihydrogen phosphate is 2:1.

[0026] Specific steps are as follows:

[0027] (1) Filter the water twice through the sand filter device and activated carbon device, pressurize the water after the second filtration, and then filter it with RO reverse osmosis membrane, and perform ultrasonic treatment on the water after reverse osmosis treatment to obtain high-energy small Molecular water;

[0028] (2) Prepar...

Abstract

The invention discloses a kappa-carrageenan-containing fountain solution prepared from high-energy small molecule water. The fountain solution is composed of the following raw materials in parts by weight: 70-85 parts of water, 10-15 parts of kappa-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 part(s) of polyoxyethylene fatty acid ester and 1-2 part(s) of an organic silicon defoamer. According to the fountain solution disclosed by the invention, the kappa-carrageenan and the konjac gum are compounded to be used as a hydrophilic film forming agent, so that the durability of a water film is improved, and the fountain solution has good wettability and permeability during use; and kappa-carrageenan-konjac gum-tea polyphenol microspheres have the characteristics of fine average particle size and slow release of tea polyphenol, and tea polyphenol is slowly released when the fountain solution is used, so that the oxidation resistance of tea polyphenol is greatly improved and the use stability of the fountain solution is guaranteed.

Description

technical field [0001] The invention relates to the technical field of offset printing fountain solution, in particular to a fountain solution containing κ-carrageenan prepared from high-energy small molecule water 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...
