Description

technical field

[0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a thermal insulation coating, a preparation method thereof, and a thermal insulation coating. Background technique

[0002] At present, fiber linings with high temperature resistance and low thermal conductivity are mostly used in all high temperature resistant furnaces such as iron and steel metallurgical furnaces, heavy non-ferrous metal metallurgical furnaces, chemical industry furnaces, and industrial calcining furnaces. Although the thermal insulation effect of these furnace linings is relatively good, under the action of harsh atmosphere, wind speed, slag corrosion and thermal shock, after a certain period of use, crystallization, pulverization, and slag removal will occur, thereby destroying the overall structure of the furnace lining. Lead to a reduction in the service life of the high temperature furnace.

[0003] In order to solve the above probl...
