The invention provides a water-based inorganic zinc silicate coating and a preparation method thereof. According to the water-based inorganic zinc silicate coating provided by the invention, a first component comprises 10-25 parts of a silane monomer, 0.05-3 parts of acid, 5-15 parts of a silane coupling agent, 5-15 parts of acrylic resin and 60-70 parts of deionized water, silane hydrolysate generated by reaction of the first component is taken as a film forming matter as one component, and zinc powder and alkaline powder in a second component are taken as the other component; during construction, the silane hydrolysate is uniformly mixed with the zinc powder and the alkaline powder, the acidic silane hydrolysate is further subjected to polycondensation under the action of the alkaline powder to form a dense coating mainly comprising Si-O-Si bonds, and meanwhile, the corrosion-resistant effect on a base material is achieved by combining the cathode protection effect of the zinc powder.

The invention provides a nitrogen-sulfur-doped carbon quantum dot modified epoxy resin coating as well as a preparation method and application thereof. According to the nitrogen-sulfur-doped carbon quantum dot modified epoxy resin anticorrosive paint provided by the invention, a nitrogen-sulfur-doped carbon quantum dot modified epoxy resin anticorrosive coating is formed on the metal surface, the impedance value is increased by 1000 times compared with that of a blank epoxy resin coating, no obvious corrosion product is observed after a 72-hour salt spray test, and the corrosion resistance value of the nitrogen-sulfur-doped carbon quantum dot modified epoxy resin anticorrosive paint is greatly improved. Therefore, the nitrogen-sulfur doped carbon quantum dot modified epoxy resin anticorrosive coating has relatively good corrosion protection performance on metal. In addition, the nitrogen and sulfur doped carbon quantum dot modified epoxy resin anticorrosive coating can form an adsorption ...
