Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a water-based graphene anti-corrosion coating. Background technique [0002] With the development of low-pollution coating industry and coating process, water-based coatings are rising day by day. The use of water-based coatings reduces the pollution of organic solvents to the environment and ensures the health of operators. Its safe and environmentally friendly production and transportation methods are widely favored. However, the current commercially available water-based anti-corrosion coatings are difficult to compete with solvent-based coatings in terms of anti-corrosion performance, poor water resistance, and salt spray resistance time is less than half of solvent-based coatings, which greatly limits the development of water-based coatings. Contents of the invention [0003] The object of the present invention is to provide a water-based graphene anti-corrosion coa...
