Embodiment Construction

[0018] The present invention will be described in further detail below by specific embodiment:

[0019] The present invention screens temperature-sensitive pigments, temperature-indicating paint color-aiding fillers, adhesive pigments, uniform color-developing base materials, and dissolving base material solvents and diluents, and selects pigments, fillers, base materials, and solvents from selected raw materials according to certain conditions. According to the proportional formula, an irreversible three-color temperature-indicating paint based on isotherm identification was prepared. In this embodiment, the prepared irreversible three-color temperature display paint based on isotherm identification is composed of zinc titanium yellow with a mass ratio of 16.2%, antimony tin yellow with a mass ratio of 3.0%, and carbon dioxide with a mass ratio of 16.0%. Zirconium, 1.1% yttrium trioxide by mass ratio, 27.8% high-temperature organic resin 805 by mass ratio, 27.8% xylene by 27....

Abstract

The invention relates to an irreversible three-color temperature indicating paint based on isotherm identification and a coating manufacturing method. The irreversible three-color temperature indicating paint based on isotherm identification is composed of, by mass, 15.2%-17.2% of zinc titanium yellow, 2.8%-3.2% of antimony tin yellow, 15.5%-16.52% of zirconium dioxide, 0.9%-1.3% of yttria, 29.0%-31.0% of high-temperature organic resin 805, 26.8%-28.8% of xylene and 5.4%-6.4% of n-butyl alcohol. The irreversible three-color temperature indicating paint based on isotherm identification can accurately form an isotherm, so that the temperature distribution condition of the surface of an object can be conveniently and accurately judged.

Description

technical field [0001] The invention relates to a functional coating used for testing the surface temperature of high-temperature parts, in particular to an irreversible three-color temperature-displaying paint based on isotherm identification. Background technique [0002] Irreversible temperature-indicating paint is a functional paint that is coated on the surface of an object and can display different colors according to the surface temperature of the object and is irreversible. Since the temperature-indicating paint can be conveniently coated on the surface of the object to be measured, it is not limited by the shape, structure and motion state of the object, especially when used on high-speed rotating parts without any restrictions, and can complete the measurement that is difficult or difficult to handle with thermocouples . Moreover, due to its irreversibility, the irreversible temperature-indicating paint can avoid the error caused by the temperature drop and has hi...
