Abstract
The invention relates to a super high-temperature resistant coating and a preparation method thereof. The coating comprises the following components in part by weight: 40 to 60 parts of organosilicon modified resin, 20 to 45 parts of coated metal powder, 10 to 15 parts of additive and 10 to 25 parts of solvent. Compared with the prior art, the super high-temperature resistant coating can protect a metal surface from being corroded in the operating state and high and low temperature alternating state of ultrahigh-temperature equipment, and has the advantages that: (1) the coating has excellent temperature-resistant performance and can be used at the temperature of higher than 800 DEG C for a long time; (2) the coating has the extremely good corrosion resistance on the premise of having excellent temperature tolerance; (3) the phenomena such as cracking, rusting and the like cannot be generated when an ambient temperature suddenly drops; and (4) priming paint is the same as the coating with easy construction.
