Abstract

The invention provides an anticorrosion conductive coating for a grounding grid and a preparation method thereof. The anticorrosion conductive coating for the grounding grid is prepared by mixing two components A and B in site according to a mass ratio of 100:2 to 100:8, wherein the component A is prepared by mixing the following substances in percentage by mass and filtering the mixture by a filter screen with a specification of 60 to 100 meshes: 8 to 15 percent of n-butyl acetate, 8 to 15 percent of cellulose acetate butyrate, 8 to 15 percent of natural asphalt, 8 to 15 percent of benzene mixture, 3 to 5 percent of conductive mica powder, 9 to 11 percent of nano graphite powder, 8 to 12 percent of isophorone, 0.3 to 0.7 percent of nano silver powder, 20 to 25 percent of fluorocarbon resin, 3 to 7 percent of propylene glycol methyl ether acetate, 0.1 to 0.3 percent of dispersing agent 923s, 0.05 to 0.15 percent of antifoaming agent 5500 and 0.05 to 0.15 percent of leveling agent 455; the component B is prepared by mixing 20 to 30 percent of a curing agent 3390, 20 to 30 percent of a curing agent TPA-90SB and 40 to 60 percent of n-butyl acetate.

Description

technical field [0001] The invention relates to an anti-corrosion conductive coating, in particular to a anti-corrosion and long-term conductive coating for grounding grids in heavily polluted areas and a preparation method thereof. Background technique [0002] With the continuous expansion of substation capacity, the safety requirements of the power system are also getting higher and higher. The grounding grid of the power system is used to eliminate the accumulated charge of the ground equipment, and the metal that constitutes the grounding grid is directly buried in the ground. The grounding grid is a key facility to ensure working grounding, lightning protection grounding, and protective grounding in power plants, substations, and communication stations. In recent years, the power system has more and more stringent requirements for the safe operation of the grounding grid. [0003] Since the grounding device has been in the harsh underground operating environment for ...
