Description

Technical field: [0001] The invention relates to a super-hydrophobic anti-corrosion coating for grounding electrodes and a coating preparation method thereof. Background technique: [0002] As the core component of the grounding device, the grounding electrode is buried in the soil, dark and humid environment for a long time, and is easily affected by various factors such as soil pH value, water content, total salt content, various anion and cation content and microbial activity. Corrosion occurs. Due to its complex working environment, the factors affecting its corrosion are not only chemical corrosion of soil, but also stray current corrosion, electrochemical corrosion and so on. When the grounding electrode is corroded, the material of the grounding electrode is damaged, and the surface corrosion products will cause poor grounding performance, unable to meet the requirements for thermal and dynamic stability during leakage, endangering personal safety, and causing seriou...
