Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-corrosion nano-coating. Background technique [0002] Fasteners are the foundation of the development of the industrial industry, which directly affects the quality and safety of the overall mechanical products. However, fasteners will encounter some problems during use, such as loosening, rusting, seizure, and even fracture. The occurrence of these phenomena has major safety hazards or even serious accidents. For this reason, strict quality control of fasteners, correct installation, maintenance, inspection, and research and development of high-performance protective coatings are all very important, and have been highly valued by people. In addition, fasteners used in marine environments or coastal areas need to have excellent corrosion resistance. [0003] Commonly used anti-corrosion coatings include: epoxy resin coatings, polyurethane coatings, phosphorus flake resin coating...
