Description

technical field [0001] The invention belongs to the technical field of anticorrosion coatings, and in particular relates to an acid-resistant nano anticorrosion coating and a preparation method thereof. Background technique [0002] In recent years, the phenomenon of acid rain in some areas has become more and more serious. Acid rain has a strong corrosive effect on mechanical equipment and engineering buildings. Once mechanical equipment and engineering buildings are corroded by acid rain and fail, serious production accidents will occur. [0003] In addition, in some special occasions, the outer wall of mechanical equipment or pipelines will be corroded by acidic liquid or gas. Once the coating covering the outer layer fails, mechanical equipment or pipelines will be corroded rapidly. [0004] Anticorrosion technology has always been one of the important research contents in the field of coating research at home and abroad. There are various anti-corrosion treatment met...
