Thepreparation technology of the coating is simple, and industrialized production can be achieved easily.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a conductive anticorrosion coating and a preparation method thereof. Background technique [0002] Conductive coatings are widely used in many fields such as power systems, oil refining industry, aerospace and electronic communication equipment, and their demand is gradually increasing. According to the mechanism of conductivity, conductive coatings can be divided into two types: structural type and blending type. Due to the complex process and high price of structural conductive coatings, blended conductive coatings have become the focus of research and development and industrialization of conductive coatings. However, the problems of high cost, high density and serious pollution of blended conductive coatings still need to be solved further resolved. [0003] In order to improve the conductive anti-corrosion coating process, reduce its cost and density, and reduce p...
