Embodiment 1

[0033] Embodiment 1: take by weighing epoxy-modified silicone resin (50%) 50g, xylene 15g, stir and mix, then add zinc titanium yellow 35g, cobalt carbonate 5g, talcum powder 8g, kaolin 15g, potassium feldspar powder 7g, 2g of barium carbonate, 2g of magnesium carbonate, 1g of calcium carbonate, and stir while adding materials to make a color paste, send the prepared color paste into a ball mill, grind and disperse, and use a scraper fineness meter to measure the fineness to no more than 30μm. , add remaining xylene 10g to the color paste after grinding and dispersing, mix thoroughly, filter and pack, and obtain a paint that is light iron yellow in color.

[0034] According to the provisions of "General Preparation Method of Paint Film" (GB1727-79), prepare a paint film on a 200×200mm high-temperature-resistant alloy steel plate. After the paint film is dry, ablate it with an oxyacetylene flame for 3 minutes to 5 After 10 minutes, naturally cool to room temperature, it can be ...

Embodiment 2

[0035] Embodiment 2. Take by weighing epoxy-modified silicone resin (50%) 50g, xylene 20g, stir and mix, then add zinc titanium yellow 35g, cobalt sulfate 6.5g, talcum powder 7g, kaolin 18g, potassium feldspar powder 7g successively , barium carbonate 2g, magnesium carbonate 2g, calcium carbonate 2g, stir while feeding, make color paste, send the prepared color paste into a ball mill, grind and disperse, measure the fineness to no more than 30 μm with a scraper fineness meter Yes, add 10g of remaining xylene to the ground and dispersed color paste, mix thoroughly, filter and pack, and obtain 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 an 800°C-1250°C multi-color irreversible temperature-indicating paint, 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 have been put forward for temperature measurement technology - simple, fast, convenient, accurate and so on. Temperature-indicating paint is a new type of temperature-measuring tool with special purposes. It is a kind of paint that indicates the surface temperature and temperature distribution of objects by color change. Because it can be effectively used in the occasions where the temperature cannot be measured, such as thermometers and thermocouples, it has been valued by the scientific and technological circles of var...
