Problems solved by technology

[0006] From the properties of conductive coatings and high-temperature-resistant coatings, we can know that the design directions of the two are different. The inner wall of the pipe for passing high-temperature gases such as chimneys needs to have good high-temperature resistance and good electrical conductivity. Difficulty in developing coatings for this environment

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a conductive anticorrosion coating used in a high-temperature environment and a preparation method. Background technique [0002] The special inner wall material of chimney-type high-temperature gas pipelines used ceramic tiles and small tiles for wall-mounting design, but this kind of design method is difficult to construct, the construction period is long, and in some special industries, the technology cannot meet the requirements. With the application and development of special anti-corrosion coatings, the internal materials of some high-temperature gas pipelines have been technically satisfied, and have greater advantages in construction than traditional materials, and the overall cost has also been greatly reduced. [0003] Pipelines for high-temperature gases such as chimneys are in a high-temperature state all year round, so the coatings coated on the inside of the pipe...
