Abstract

The invention discloses high-temperature segment multi-color irreversible temperature indicating paint. The high-temperature segment multi-color irreversible temperature indicating paint is prepared from the following components in percentage by weight: 5 to 20 parts of a color development substance, 20 to 40 parts of a high-temperature physical filler, 30 to 50 parts of high temperature resistantsilicone resin, 10 to 30 parts of a solvent A and 20 to 40 parts of a solvent B. The high-temperature segment multi-color irreversible temperature indicating paint disclosed by the invention is formed by mixing the color development substance, the high-temperature physical filler, the solvent A and the solvent B according to specific proportions, and has remarkably-obvious color change point, good temperature measuring property, measurable temperature of 800 to 1200 DEG C and measurement temperature range of about 50 to 100 DEG C; and by matched combination use, the measurement temperature range can be further narrowed and can reach 30 DEG C at minimum. The high-temperature segment multi-color irreversible temperature indicating paint disclosed by the invention is convenient to produce, simple and convenient in process and simple in process; and the high-temperature segment multi-color irreversible temperature indicating paint is suitable for measuring the surface temperatures of a continuous operation machine part and a complex structural part, or can measure temperature distribution of large-area surface of an object and also can simultaneously measure the temperatures of element parts.

Description

technical field [0001] The invention relates to a paint, in particular to a high-temperature section multi-color irreversible temperature-indicating paint and a preparation method thereof. Background technique [0002] Temperature-indicating paint is a special paint that uses color changes to indicate the surface temperature and temperature distribution of objects. Temperature-indicating paint was first used to measure the temperature of aircraft turbine engine blades, combustion chambers, nozzles, etc. It is very expensive and difficult to measure the actual temperature of rotating parts, such as turbine blades, through traditional slip ring leads and compound thermocouples, and can only measure the temperature of a single point. Similarly, high frequency pyrotechnics can only give the probe point temperature on the part where the pyrometer probe is aimed. Temperature-indicating coatings can provide a permanent, simple and relatively inexpensive solution to the problems e...
