High-temperature resistant mark coating

Abstract

High-temperature resistant mark coating is made by heating inorganic solution with molecules modified and chelated, antiseptic pigment nanometal oxide, superfine rare earth micropowder, sensitizer and thermal stabilizer. The mark coating is resistant to 1800 degrees Centigrade, bright in color, fine and smooth, fast in curing time, long lasting and non-discoloring, acid and alkali resistance is iimproved, the advantages of inorganic texture are given into play completely, adhesion is good, and the mark coating can be coated with materials and is resistant to corrosion and oxidation at high temperature and normal temperature. The high-temperature resistant mark coating is used for marking metallurgy steel, high-temperature kilns, refractory materials, communication vehicles, space flight and aviation devices.

Description

technical field [0001] High temperature resistant marking paint is a water-based inorganic, high temperature resistant and corrosion resistant paint that can be painted on metal materials at room temperature and high temperature . Background technique [0002] High temperature resistant coatings generally refer to coatings used above 200 °C. The high-temperature resistant coatings currently used in China are generally phenolic, modified epoxy coatings, silicone coatings, etc., which are not very good at high temperature resistance, and are easy to burn, which cannot meet the needs of actual production. Steelmaking, continuous casting, rolling steel, etc. are usually It is necessary to mark the surface of high-temperature steel parts to eliminate steel-mixing accidents, and high-temperature furnaces, engines and other equipment that have been working in high-temperature environments for a long time also need to be protected with high-temperature resistant coatings.

Problems solved by technology

The high-temperature resistant coatings currently used in China are generally phenolic, modified epoxy coatings, silicone coatings, etc., which are not very good at high temperature resistance, and are easy to burn, which cannot meet the needs of actual production. Steelmaking, continuous casting, rolling steel, etc. are usually It is necessary to mark the surface of high-temperature steel parts to eliminate steel-mixing accidents, and high-temperature furnaces, engines and other equipment that have been working in high-temperature environments for a long time also need to be protected with high-temperature resistant coatings

At present, the high-temperature-resistant coatings used in China are generally modified epoxy coatings and silicone coatings, etc., and there is still a gap between their high-temperature resistance and flame resistance and actual needs.
