Example Embodiment

[0019] 1. Preparation of steel grounding body:

[0020] In the first step, a batch of steel grounding rods can be customized, with a diameter of 2-3 cm and a length of 200-250 cm. The steel rods are tapered at one end, which is convenient for hitting and inserting into the ground. figure 1 Shown

[0021] In the second step, a graphene layer (2) is prepared on the above-mentioned steel rod (1) by chemical vapor deposition;

[0022] In the third step, a chemical vapor deposition method is used to prepare a graphene layer (2) on the surface of the above-mentioned steel ground body. The carbon source used can be methane, ethylene, acetylene and other gases, and the reaction auxiliary gas is hydrogen and argon, wherein hydrogen plays a reducing role and argon plays a protective role. The basic process is as follows: hydrogen and argon are introduced into the reaction, hydrogen is used to reduce and remove oxides on the metal surface, and argon plays a protective role. When the temperat...

Abstract

The invention discloses a grounding body based on a nano-conductive corrosion resistant coating which comprises a steel bar grounding body coated with a graphene coating. One end of a steel bar (1) is a cone. A graphene layer (2) is prepared on the steel bar (1). The graphene layer (2) is used as a conductive corrosion resistant coating to be used in a grounding body. According to the nano-conductive corrosion resistant grounding body, the surface of the steel grounding body is directly coated with multiple layers of graphene. Precious metal (such as copper, nickel, etc.) is replaced with the graphene material grown on the surface of the steel metal to prepare the corrosion resistant conductive grounding body, or graphene is used to cover the steel surface so as to raise antioxidant ability of the steel bar grounding body. Graphene, used as a unique two-dimensional nano-film, has good structural properties, physical properties and chemical properties. The graphene material is used as a coating to be used on the surface of the grounding body such that the metal grounding body has excellent characteristics such as high oxidation resistance, corrosion resistance, good conductivity, high mechanical strength, wear resistance and the like. From the perspective of production costs, the graphene coating requires a simple preparation technology, has low cost, and is an ideal material for replacing precious metal.

Description

technical field [0001] The invention relates to a grounding body based on a nano conductive anti-corrosion coating, in particular to a conductive coating used in a conductive anti-corrosion grounding device. Background technique [0002] Power grounding is an important guarantee for the safe operation of power supply systems and high-tech weak signal testing. Grounding and protection technology is a very important topic in international electrotechnical academic research. The widely used grounding bodies are mainly steel rods, copper-plated steel rods and galvanized steel rods. The grounding body is inserted about 2.5 meters into the ground. Generally, after 3-5 years of use, the metal layer on the surface of the grounding body will show different degrees of corrosion. , causing the grounding resistance to increase, and even the grounding effect to be lost, causing potential safety hazards. In particular, with the current increase in industrial power capacity and the incre...
