Problems solved by technology

At present, the anti-corrosion and electrostatic conductive coatings with a large amount of application are mostly solvent-based coatings such as carbon-based, metal-based or metal oxide-based coatings. However, due to the large amount added to the coating, the anti-corrosion coating often makes the Performance and electrostatic conductivity cannot be balanced, and the cost of solvent-based coatings is high, causing serious environmental pollution
[0003] With the development of water-based metal anti-corrosion coatings, water-based metal anti-corrosion conductive coatings are also emerging at the historic moment, but in general, their performance is still far behind that of solvent-based anti-corrosion conductive coatings.
In recent years, the application of nanomaterials and nanotechnology in coatings has improved and improved the adhesion, flexibility, impact resistance, antistatic and medium resistance properties of coatings to substrates to some extent, but The simple application of nano-materials is often unable to produce water-based metal anti-corrosion and conductive anti-static coatings with excellent performance in both anti-corrosion and anti-static properties. very important
