Problems solved by technology

Although the application of the particles in the preparation of inks is disclosed, there are still great defects in the application of photonic crystals as pigments in ink formulations after they are assembled. On the one hand, the structural color of the photonic crystal is whitish due to scattering, and the hue saturation is low. On the other hand, when the assembled photonic crystal is dispersed in the ink as a pigment and affected by the solvent, it will disperse into nanoparticles and lose its structural color.
Therefore, the application of "structural color" materials with environmental protection, brilliant color and iridescent effect is limited.

Abstract

The invention belongs to the field of ink preparation, and specifically discloses a preparation method of water-based ink, comprising the following steps: (1) mixing and stirring monodisperse nanometer microsphere emulsion, water-based resin, and alcohol solvent; (2) adding inorganic nano Granules, dispersant and defoamer, disperse evenly and then fully grind; (3) Add leveling agent, film-forming aid, adhesion promoter and thickener, and mix evenly to obtain water-based ink. The water-based ink of the present invention can be used to prepare printed matter with structural color light-changing characteristics. After printing, monodisperse nano-microspheres are assembled to form a hexagonal close-packed structure, thereby forming an ink layer with photonic crystals. The color and luster energy produced by the photonic band gap structure As the viewing angle changes, the iridescent effect appears, and the color and gloss of the ink print are relatively independent and can be combined with each other, thereby forming colorful visual effects.

Description

technical field [0001] The invention belongs to ink, and in particular relates to a preparation method of water-based ink and an ink formula. Background technique [0002] Ink is a colloidal dispersion system composed of pigment (dye) material, filler, binder, solvent, auxiliary agent, etc. It is an indispensable coloring material used in the printing process. Through printing, the pattern and text are displayed on the substrate, which is used for various printings such as books, periodicals, packaging, and decoration. With the continuous emergence of new dyes and pigments, inks with different hues, lightness, and saturation appear one after another. While meeting the colorful color requirements, people hope that inks can provide magnificent effects such as metallic texture and pearl color. Noble and gorgeous image. As a result, pearlescent inks, metallic inks and other inks added with effect pigments appeared. These inks are prepared by using tiny metal flakes or pearlesc...
