Embodiment 1

[0033] Example 1: Weigh 50g epoxy-modified silicone resin (50%), 15g xylene, stir and mix, then add 35g zinc titanium yellow, 5g cobalt carbonate, 8g talc, 15g kaolin, 7g potash feldspar powder, 2g of barium carbonate, 2g of magnesium carbonate, and 1g of calcium carbonate. Stir while adding materials to make a color paste. Send the prepared color paste to a ball mill, grind and disperse, and measure the fineness to no more than 30μm with a scraper fineness meter. , Add the remaining 10g of xylene to the milled and dispersed color paste, mix well, filter and pack, and get a light iron yellow paint.

[0034] Prepare the paint film on a 200×200mm high-temperature alloy steel plate according to the "General Preparation Method of Paint Film" (GB1727-79). After the paint film is completely dry, ablate it with an oxyacetylene flame for 3 minutes to 5 minutes. Minutes later, cool down naturally to room temperature. From the low temperature zone to the high temperature zone, the coating ...

Embodiment 2

[0035] Example 2. Weigh 50g of epoxy-modified silicone resin (50%), 20g of xylene, stir and mix, then add 35g of zinc titanium yellow, 6.5g of cobalt sulfate, 7g of talc, 18g of kaolin, and 7g of potash feldspar powder. , Barium carbonate 2g, Magnesium carbonate 2g, Calcium carbonate 2g, stir while adding materials to make color paste, send the prepared color paste to a ball mill, grind and disperse, use a scraper fineness meter to measure the fineness to no more than 30μm. Yes, add 10g of the remaining xylene to the milled and dispersed color paste, mix well, filter and pack, and get a light iron yellow paint.

Abstract

The invention discloses a 800DEG C-1250DEG C multi color-changing irreversible thermopaint, which is prepared by taking epoxy modified organic silicon resin as an adhesive and a high temperature resisting yellow pigment for underpainting, and adding a cobalt pigment, a silicate filling material, part of metal carbonates and a diluent. The paint is mainly used for temperature measurement of dynamic operating parts and large-area temperature fields, and a painted film has the characteristics of good physical and mechanical properties, sensitive color change, obvious color difference and high precision, etc.

Description

Technical field [0001] The invention relates to a multicolor irreversible temperature-indicating paint at 800°C to 1250°C, which is used for temperature measurement of dynamic operating parts and large-area temperature fields, especially for environments where thermometers and thermocouples cannot be directly used for temperature measurement. Background technique [0002] With the rapid development of modern industry and science and technology, new requirements for temperature measurement technology-simple, fast, convenient, accurate, etc. are put forward. Temperature indicating paint is a new type of temperature measuring tool with special purpose. It is a kind of paint that indicates the temperature and temperature distribution of the surface of the object by color change. Because it can be effectively used in occasions where temperature cannot be measured, such as thermometers and thermocouples, it has attracted the attention of scientific and technological circles in various...
