Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and in particular relates to an environment-friendly water-based anti-corrosion conductive static coating and a preparation method thereof. Background technique [0002] With the development of science and technology, microelectronics technology has been widely used in recent years, so that the electromagnetic environment is becoming more and more complex. How to prevent electrostatic hazards has become an urgent problem to be solved. Static electricity can accumulate on non-metallic materials, and when it reaches a certain level, it will discharge to break down electronic components, cause explosion of dangerous goods such as oil or gunpowder, and interfere with the operation of aircraft. The manufacturing and use environment of electronic components and equipment also put forward higher requirements for electrostatic protection materials. [0003] Static conductive coatings can be c...

AI Technical Summary

Problems solved by technology

Conductive fillers include conductive carbon black, graphite, carbon fiber, and metal and metal oxide powders, etc. These fillers are quite different from polymer structures and have poor dispersion. They need to be filled with a higher volume fraction to achieve the electrostatic protection effect, which affects the coating. Adhesion, impact strength and other physical and mechanical properties

[0004] At present, domestic electrostatic conductive coatings are generally solvent-based, which not only requires expensive organic solvents, but also wastes resources and causes serious pollution to the environment.
