Problems solved by technology

However, although copper materials have a good anti-corrosion effect, they are expensive, and will cause heavy metal pollution, which will have a huge impact on the surrounding environment.
[0004] It can be seen that the traditional anti-corrosion measures have more or less certain defects, either causing pollution to the environment, or the anti-corrosion effect is not very good, or the cost is high, and it cannot protect the grounding device from environmental protection, long-term and economical anti-corrosion effect

Abstract

The invention discloses an environment-friendly long-acting grounding device anticorrosive agent and a preparation method of the anticorrosive agent. The environment-friendly long-acting grounding device anticorrosive agent is prepared from the following components in percentage by mass: 90.2-94.9% of calcium bentonite, 0.7-0.9% of Na2B4O7, 0.6-2.8% of Na2SiO3, 0.7-2.0% of NaHCO3 and 1.2-5.4% of Na2CO3. The environment-friendly long-acting grounding device anticorrosive agent is capable of effectively preventing oxygen from permeating into a metal grounding electrode and preventing the metal grounding electrode from oxidation corrosion caused by the oxygen, and therefore, the metal grounding electrode is better in corrosion resistance, and the grounding body structure has stable and long-term excellent electrical conductivity.

Description

technical field [0001] The invention mainly relates to the technical field of grounding device anticorrosion, in particular to an antiseptic for grounding device based on environmental protection and long-acting performance and a preparation method. Background technique [0002] The grounding device will be subject to chemical corrosion and electrochemical corrosion in the soil, especially in places with soft soil and high water content, where the soil resistivity is low, and the corrosion rate is very fast, which will cause the grounding electrode to rust and increase the grounding device Grounding resistance, when the corrosion reaches a certain level, it will even cause partial fracture of the grounding grid, which will endanger the safety of personal equipment in the event of a grounding short circuit. And after a failure occurs, the grounding device must be excavated for inspection and transformation, which will consume huge financial and material resources. Therefore,...
