Abstract

The invention belongs to the field of metal coatings, and in particular relates to a coating that can be used at high temperatures and is corrosion-resistant; the technical problem to be solved by the invention is to provide a coating that still has strong mechanical strength, strong adhesion, Corroded paint; in order to solve the above problems, the technical solution provided by the present invention is: a high-temperature anti-corrosion paint, including base material, solvent, curing agent, pigment and filler, silane coupling agent, drier, auxiliary agent; the present invention The beneficial effect is that: it has good adhesion, impact resistance and mechanical strength, the thickness of the coating film is 50 μm, the coating can withstand the temperature of 600 ° C, and has good corrosion resistance.

Description

technical field [0001] The invention belongs to the field of metal coatings, in particular to a coating that can be used at high temperatures and is corrosion-resistant. Background technique [0002] Most of the anti-corrosion coatings belong to the category of normal temperature anti-corrosion, while the dust collector for the exhaust gas of the cement plant, the high-temperature and high-pressure reaction kettle in the petrochemical plant and the boiler in the thermal power plant are mostly operated in high-temperature strong corrosive gases such as sulfur and chlorine for a long time. Under such harsh conditions, the service life of metal equipment is reduced, production costs are increased, and major hidden dangers are brought to safe production. In recent years, some high-temperature anti-corrosion materials have also been developed, but there are problems such as weak mechanical strength, poor adhesion and easy corrosion resistance.
