Problems solved by technology

In order to prevent the grounding rod from being oxidized and corroded, the surface of the grounding rod is usually plated with copper or coated with conductive paint. The copper plating layer will still be corroded, but the speed of corrosion will be delayed; the commonly used conductive paint is graphite or nickel. The conductive coating made of graphite is easy to crack after drying, which makes the sealing performance poor, and the nickel powder is easily oxidized. After the nickel powder is mixed with organic polymer materials, the interface is clear, and the sealing performance is poor, which leads to corrosion of electrolytes

Description

technical field [0001] The invention belongs to the technical field of conductive materials, and in particular relates to a conductive anticorrosion coating and a preparation method thereof. Background technique [0002] The conductive grounding rod is a key component of power grounding in the power system. Since the grounding rod is made of iron, it is easily oxidized and corroded when it is exposed to the air or inserted into the ground during use. In order to prevent the grounding rod from being oxidized and corroded, the surface of the grounding rod is usually plated with copper or coated with conductive paint. The copper plating layer will still be corroded, but the speed of corrosion will be delayed; the commonly used conductive paint is graphite or nickel. The conductive coating made of graphite is easy to crack after drying, which makes the sealing performance poor, and the nickel powder is easy to be oxidized. After the nickel powder is mixed with the organic po...
