Abstract

The invention discloses a color ink for packaging and a preparation method thereof. The color ink for the packaging is prepared from the following materials in parts by weight: 12-45 parts of waterborne polyester resin, 5-10 parts of persimmon tannin, 10-35 parts of activated snail powder, 15-25 parts of polymeric silicate-aluminum sulfate, 5-16 parts of L-carnitine, 15-28 parts of modified starch, 1-3 parts of pigments and 55-85 parts of deionized water. The activated snail powder is prepared by a following method that snails are shelled and put into a citric acid solution for soaking for 5-10h, then the shelled snails are frozen at a temperature of minus 78 DEG C for 20-40h, then frozen snail meat is placed in steam of 120-125 DEG C for 1-2h, then steamed snail meat is dried, pulverizedand mixed with sodium carbonate according to the ratio of 1 to 0.3, and the mixture is placed under the temperature of 100-115 DEG C for drying for 20-40 min and then taken out for grinding and screening to 100-200 mesh. The color ink has the advantages such as high drying speed, lower chemical agent content, high antibacterial rate, high adhesion fastness, low friction coefficient, high temperature resistance and good corrosion resistance, and is suitable for using on the packaging.

Description

technical field [0001] The invention relates to a colored ink, in particular to a colored ink used for packaging and a preparation method thereof. Background technique [0002] Ink (ink, printing ink) is an important material for printing, which expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of pigments, linking materials, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. Existing inks have disadvantages such as slow drying speed and very high chemical preparation content, and are not suitable for use on packaging. Therefore, the present invention provides a color ink for packaging and a preparation method thereof. Contents of the invention [0003] The object of the present invention is to provide a color in...
