Description

technical field

[0001] The invention relates to a coating and a preparation method thereof, in particular to a graphene-based high temperature resistant anticorrosion coating and a preparation method thereof. Background technique

[0002] High temperature resistant coating is an important coating, which is suitable for anticorrosion of chimney flue, high temperature steam pipe, heat exchanger, high temperature furnace, high temperature desulfurization equipment, petroleum and petrochemical cracking device, engine parts and exhaust pipe. In addition, some special high-temperature-resistant anti-corrosion coatings are widely used in aerospace, petroleum and petrochemical, metallurgy, electric power, and national defense fields. Since the industrial production of organic silicon in the 1940s, the high-temperature resistant coatings formulated with its products have been widely used in high-temperature motors and electrical insulation. For example, organosilicon-aluminum powder...
