Temperature-sensitive color-changing art coating and preparation method thereof

Abstract

The invention discloses a temperature-sensitive color-changing art coating and a preparation method thereof. The coating comprises the following raw materials in percentage by weight: 50-60 parts of water, 5-8 parts of reversible color-changing pigment, 8-10 parts of calcium carbonate, 3-5 parts of auxiliaries, 5-8 parts of titanium dioxide, 5-8 parts of kaolin, 2-3 parts of dihydric alcohol, 10-15 parts of silicon-containing acrylic polymer, 5-10 parts of temperature sensing agent, 8-10 parts of inorganic pigment, 10-12 parts of acrylic resin, 8-12 parts of mannitol and 2-5 parts of alkylphenol polyoxyethylene ether. The coating has the advantages of super-strong adhesive force, good stability, good light resistance, good heat resistance, good aging resistance and the like; in addition, the coating also has the advantages of high chemical resistance and fullness, and can be used as an auxiliary film-forming substance to be combined with the modified temperature sensing agent with good wear resistance and chemical resistance, and the reversible temperature indicating coating with excellent performance can be obtained under the reasonable proportion of the modified temperature sensing agent, the wetting agent and the defoaming agent.

Description

technical field [0001] The invention relates to the field of temperature-indicating paints, in particular 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. [0003] After searching, it was found that the invention of application number CN201810743916.4 relates to a modified temperature-sensing agent, a reversible temperature-indicating coating and its preparation method ...

AI Technical Summary

Problems solved by technology

[0006] For functional materials, they have 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, aging resistance, etc. Performance is far inferior to ordinary pigments
