Problems solved by technology

However, so far, the development of heavy-duty anti-corrosion coatings in China still cannot meet the needs of large-scale engineering construction. High-tech anti-corrosion coatings are far behind the actual demand in terms of variety and quality, and the problem of short validity period is common. Anti-corrosion coatings with special properties, especially high-solid, solvent-free heavy-duty anti-corrosion coatings, cannot meet the long-term anti-corrosion requirements of a large number of offshore and coastal facilities, water conservancy projects, petrochemical projects and metallurgical construction projects in China

Embodiment Construction

[0011] Firstly (1) make the pre-made lithium bentonite into a gel, then add a certain amount of water and additives, add refractory aggregate bauxite and additives after ball milling for 20 minutes, continue ball milling for 30 minutes (2) mix the silicon-fluorine solution Stir and ripen at high speed, the speed of the mixer should reach more than 3500 / min, stir for more than 30 minutes, and leave the stirred solution for more than 2 hours to mature; (3) gradually add the mature silicon-fluorine solution to the ground under stirring at 3000 / min Lithium-based bentonite bauxite-based powder, yttrium oxide, composite α-ceramic micropowder, silicon carbide, silicon dioxide powder, magnesium oxide, etc. chelate and stir for 30 minutes. Finally, boric acid is added for stabilization.

Abstract

The invention provides a high-temperature-resistant and anticorrosive composite ceramic coating which is a high-technology environment-friendly energy-saving coating resistant to high temperature and acid-base corrosion and high in abrasion resistance. An advanced high-temperature-resistant silicon-fluorine modified film-forming solution is adopted, various kinds of pigment are formed in a chelating mode under the closed high-temperature condition, and the resistant temperature can be 1200 DEG C. As compact ceramic glaze is formed at high temperature, the coating has the advantages of being high in hardness, resistant to impact, long-acting in corrosion, good in adhesive force, resistant to abrasion, long in service life and the like, meets the requirement for large-scale engineering construction in industry in China, and can be widely applied to the acid-base long-term corrosion environment, the organic solvent corrosion environment, chemical material storing tanks, and the high-corrosion and high-friction environment.

Description

technical field [0001] Composite ceramic high-temperature anti-corrosion coating is a high-tech coating with a unique polymer structure and extremely high hardness and flexibility. It is also an environmentally friendly and energy-saving coating that is resistant to high temperatures, organic solvents and acid and alkali corrosion. High-tech anti-corrosion coating. Background technique [0002] Our country has successfully developed a variety of industrial anti-corrosion coatings, which play an important role in the anti-corrosion of metal structures. However, so far, the development of heavy-duty anti-corrosion coatings in China still cannot meet the needs of large-scale engineering construction. High-tech anti-corrosion coatings are far behind the actual demand in terms of variety and quality, and the problem of short validity period is common. Anti-corrosion coatings with special properties, especially high-solid, solvent-free heavy-duty anti-corrosion coatings, cannot m...
