Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anticorrosion coating and a preparation method thereof. Background technique [0002] With the continuous development of the national economy and basic construction, the anti-corrosion requirements of national key projects and large-scale projects are getting higher and higher, and large-scale steel equipment, components, pipelines and other steel structure facilities are increasing. In order to ensure the service life of these steel structures, it is necessary Take efficient and durable protective measures, among which coating protection is the most commonly used anti-corrosion method for steel structures. An ideal coating requires that the coating that forms the coating not only has excellent anti-rust and anti-corrosion properties, but also must have good workability, adaptability and durability. [0003] At present, the vast majority of anti-corrosion coatings...
