Problems solved by technology

However, as a functional material, it has not been successfully applied to architectural coatings, which has a lot to do with the instability of the reversible thermotropic pigment itself, which will lead to its light resistance, heat resistance, and aging resistance. Performance is far inferior to ordinary pigments

Abstract

The invention discloses temperature-sensitive colour-changeable artistic coating and a preparation method thereof. The temperature-sensitive colour-changeable artistic coating is prepared from the following raw materials in percentage by weight: 20-30% of water, 0.1-1% of a thickening agent, 0.1-0.5% of auxiliary, 0.1-1% of a dispersing agent, 0.1-0.5% of a wetting agent, 0.1-0.5% of a defoaming agent, 5-20% of titanium dioxide, 5-10% of kaolin, 0.1-0.5% of bactericide, 0.1-0.5% of a mould inhibitor, 0.5-1.0% of dihydric alcohol, 0.5-1.5% of a coalescing agent, 30-40% of silicon-containing acrylic polymer and 0.5-10% of microcapsule temperature-sensitive colour powder. The prepared temperature-sensitive colour-changeable artistic coating has good reversible colour changing function, excellent paint film properties in adhesion, handfeel, doodling resistance, concave-convex three-dimensional texture effect and the like and can provide more personalized colour space and creative artistic function for people in the aspect of decoration and renovation of buildings.

Description

technical field [0001] The invention relates to a temperature-sensitive color-changing art paint and a preparation method thereof. Background technique [0002] Thermochromic coatings are functional coatings that use reversible thermochromic materials as pigments, which undergo color changes when stimulated by external conditions, and return to their original colors after the excitation source is removed. The research on thermally reversible discoloration materials started earlier at home and abroad, and there are many types. The successful development of different types of reversible discoloration materials not only broadens the temperature range of discoloration, but also enriches the color changes. The discoloration temperature and color can be freely selected according to the needs. It is widely used in industrial coatings and is suitable for surface coating of daily necessities such as drinking water cups, electric kettles, tableware, bowls, baby bathtubs, etc. that req...
