Color-variable art paint and preparation method thereof

Abstract

The invention discloses a color-variable art paint and a preparation method thereof, belonging to the technical field of water-based paints. The color-variable art paint comprises the following components in parts by mass: 20-30 parts of deionized water, 0.1-1 part of a thickener, 0.1-2.5 parts of a pH value regulator, 0.1-1 part of a dispersant, 1-3 parts of an antifoaming agent, 0.1-0.5 part ofa wetting agent, 0.1-0.5 part of a bactericide, 0.1-0.5 part of a mold inhibitor, 0.1-0.5 part of an antifreezing agent, 0.5-1.5 parts of a film forming aid, 30-40 parts of an acrylic emulsion, 5-15 parts of a photosensitive color-variable material and 25-30 parts of glass beads. The color-variable art paint overcomes the shortcoming of inclusion of volatile solvents in conventional color-variablepaints, and has a solid content of 100%. At the same time, the paint does not emit organic solvents and chemical emulsifiers, can change color with light, presents different colors with light, and achieves the purpose of beautifying the environment.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a color-changing art paint and a preparation method thereof. Background technique [0002] Color-changing art paint refers to a special paint whose color changes with environmental conditions such as light, temperature, electric field, magnetic field, etc., especially photochromic art paint, which can absorb sunlight / ultraviolet energy under light irradiation , resulting in a change in the molecular structure, resulting in a change in the absorption wavelength, resulting in a change in color; when sunlight / ultraviolet energy is lost, the original molecular structure is restored and the original color is restored. This kind of color-changing material started earlier at home and abroad, with a wide variety, and is widely used in industry, children's toys, and some candy packaging. Moreover, as a color-changing material, cobalt salts are mostly used as color-changing pigme...

Problems solved by technology

This kind of color-changing material started earlier at home and abroad, with a wide variety, and is widely used in industry, children's toys, and some candy packaging. Moreover, as a color-changing material, cobalt salts are mostly used as color-changing pigments, but cobalt salts have Toxicity, which mainly harms its direct contacts, and is less harmful in the process of consumer use, but still has a certain degree of harm

[0003] At present, people's requirements for architectural coatings are getting higher and higher, and they are becoming more and more diverse. Therefore, it is necessary to provide a water-based environmentally friendly color-changing art paint, which can make up for this vacancy, solve the problem of single wall color, and make the wall surface more attractive. The color of the environment can also change with the change of light, so as to meet the individual and artistic requirements of people's decoration
