Description

technical field [0001] The invention belongs to the technical field of conductive coatings, and in particular relates to a carbon nanotube modified conductive anticorrosion coating for grounding grids. Background technique [0002] The grounding grid is a necessary safety facility to ensure working grounding, lightning protection grounding, and protective grounding in power plants, substations, and power equipment for transmission lines. In power systems such as power transmission, distribution, and transformation, the contact resistance between the grounding grid and the earth is required to be as small as possible. If the grounding grid is severely corroded, a short circuit will occur in the live equipment during operation and the grounding grid will be blown, resulting in potential Lifting, causing personal equipment accidents. The development of coatings with anti-corrosion and conductive functions provides a new way to solve the corrosion problem of grounding materials...

Problems solved by technology

At present, the existing conductive coatings have poor corrosion resistance, and the anti-corrosion coatings with better corrosion resistance have low electrical conductivity. It is urgent to develop a coating that is both anti-corrosion and conductive.
