Abstract

The invention discloses a preparation method of a water-soluble photochromic ink. The method comprises the following steps: (1) preparing a diatomite / antimicrobial composite; (2) adding a styrene-acrylic emulsion into a container, and dropwisely adding the diatomite / antimicrobial composite water solution while stirring; stirring to obtain an antimicrobial dispersion solution; (3) adding an EVA (ethylene-vinyl acetate) emulsion into the container, dropwisely adding a diatomite / inorganic oxide water solution and a photochromic composite while stirring, and continuing stirring for 30-60 minutes to obtain a photochromic dispersion solution; (4) mixing the antimicrobial dispersion solution and photochromic dispersion solution, adding deionized water, alcohol ester-12, PE (polyethylene) water-based wax, an ink compound, a water-based leveling agent, a water-based defoaming agent and a nonionic surfactant into a dispersion kettle, and stirring to obtain the water-soluble photochromic ink. The ink has the characteristics of excellent antimicrobial property, excellent formaldehyde resistance and excellent deodorizing property, is photochromic, and satisfies the multifunctional demands, thereby widening the application range of the ink.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a preparation method of water-soluble photochromic ink. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of pigments, linking materials and additives. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. However, the single function of traditional ink can no longer meet the diverse needs of people. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of water-soluble phot...
