Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a static conductive coating, in particular to a water-based nano static conductive coating and a preparation method thereof. Background technique [0002] Static conductive coatings are often applied to areas or parts that need to control the hazards caused by static electricity to eliminate disasters caused by static electricity, such as oil storage tanks, oil pipelines, computer rooms, etc. In the traditional anti-corrosion coatings, there are a lot of organic solvents, which are easy to volatilize in the process of operation, which will damage human health and pollute the environment. The water-based electrostatic conductive coating does not use solvents in the manufacturing process, and has a very low content of volatile organic compounds, which makes the operation safer. It is especially suitable for the anti-corrosion and static-conductive requirements of petroleum storage t...
