High-temperature resistant coating

Abstract

The invention provides a high-temperature resistant coating which comprises, by weight, 15%-50% of epoxy modified organic silicon resins, 5%-15% of high-temperature resistant composite inorganic pigments, 10%-20% of silicate fillers, 3%-10% of rust resisting pigments, 5%-20% of mixed type glass powders free from lead and boron, 1%-8% of adhesion promoters and 5%-40% of viscosity regulation solvents. The high-temperature resistant coating has the advantages of being easy to solidify at normal temperatures, high in hot and cold alternation resistant capacity, adhesive forces of coating films and high temperature corrosion resistant capacity, difficult to crack, convenient to prepare and use and energy-saving.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a high temperature resistant coating. Background technique [0002] With the rapid development of modern industry and national defense construction (such as aerospace, aviation, weapons, etc.), the requirements for high-temperature resistant coatings for equipment are getting higher and higher. Physical and mechanical properties and anti-corrosion properties. [0003] High-temperature resistant coatings are widely used in high-temperature places such as steel chimneys, high-temperature pipes, high-temperature furnace shells, petroleum cracking devices, tanks, and artillery, to delay the thermal hydrogenation corrosion of metal equipment such as steel at high temperatures, and ensure long-term use of equipment. [0004] At present, there are many reports on heat-resistant coatings, and the heat-resistant properties of existing high-temperature-resistant coatings can basically m...

AI Technical Summary

Problems solved by technology

[0005] The invention proposes a high-temperature-resistant coating, which solves the problems in the prior art that conventional high-temperature-resistant coatings need to be cured at high temperature, have poor adhesion to the base material of the paint film, poor resistance to cold and heat alternation of the paint film, are easy to crack, and have poor corrosion resistance at high temperatures.
