Abstract

Disclosed is color-variable environment-friendly paint. The color-variable environment-friendly paint is prepared by, by weight, 30-40 parts of organic silicon resin, 40-50 parts of bismuth vanadate, 10-15 parts of hybi, 20-30 parts of poval, 10-20 parts of Sl203, 20-30 parts of talcum powder, 8-15 parts of mica powder, 6-10 parts of organic silicon coupling agent, 20-30 parts of xylene, 2-4 parts of dispersant, 1-3 parts of anti-settling agent and 3-5 parts of defoamer. The color-variable environment-friendly paint is excellent in reaction time within a range of 50-70 DEG C, low in color changing temperature, short in restoring time and reversible in color changing effect. The color-variable environment-friendly paint is smooth in coating, high in hardness, large in adhesive force, excellent in water resistance, less prone to aging, convenient in operation and simple in process, and has relatively-wide industrial application range.

Description

technical field [0001] The invention relates to an environment-friendly coating, in particular to a color-changing environment-friendly coating and a preparation method thereof. Background technique [0002] Coatings can protect, decorate, mark and other purposes on the surface of materials in industry, and are generally composed of film-forming substances, fillers (pigments and fillers), solvents, and additives. According to the performance, there are anti-corrosion paint, insulating paint, conductive paint, heat-resistant paint, color-changing paint, etc. Among them, the color-changing paint is a special paint that uses color changes to reflect the surface temperature and temperature distribution of the object. Under certain conditions, heating the object to a certain temperature will change the color of the paint on the surface of the object, thereby determining the color change temperature of the paint. . In industrial applications, it is mostly used as an over-tempera...
