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.

Description

technical field [0001] The invention relates to coatings, in particular to a super high temperature resistant coating and a preparation method thereof. Background technique [0002] At present, with the continuous adjustment and updating of production processes in various chemical plants, oil refineries, and power plants, various devices such as: high-temperature boilers, exhaust devices, chimneys, etc. have higher and higher requirements for various functions of heat-resistant coatings. It turns out that the temperature range of traditional heat-resistant coatings is usually up to 700 ° C, and the temperature resistance is poor. When the high-temperature device returns to normal temperature, the defect of poor corrosion resistance of the heat-resistant coating will be exposed; therefore, the market urgently needs a A temperature-resistant anti-corrosion coating with a temperature resistance of about 800°C, good temperature denaturation resistance and excellent anti-corrosio...
