Abstract

The invention discloses a preparation method of a corrosion-resistant and scouring-resistant resistance reducing agent, and belongs to the technical field of conductive material preparation. Graphiteand alunite react with potassium permanganate in a sulfuric acid environment to generate a graphene oxide component, meanwhile, aluminum ions in the alunite are dissolved in the solution to form a free state, afterwards, coconut shreds are added and decomposed in the sulfuric acid solution, a plant fiber component is separated and extracted, and aluminum ions and graphene oxide nanoparticles are dispersed in the fiber component, so that the mechanical strength and the bonding performance of the fiber are enhanced, and it is avoided that the durability of the resistance reducing agent is reduced due to the fact that the resistance reducing agent is scoured by rainwater. Aluminum ions react with alkali liquor and are sintered at high temperature to generate aluminum oxide nano-scale particles, the aluminum oxide nano-scale particles are dispersed in plant fibers, and the fiber component is dispersed in the resistance reducing agent to further improve the rain wash resistance of the resistance reducing agent. The fiber component is subjected to high-temperature treatment and carbonization to generate carbon fibers, and meanwhile a graphene component is embedded to enhance the conductivity of the resistance reducing agent.

Description

technical field [0001] The invention discloses a preparation method of a corrosion-resistant and scouring-resistant drag reducing agent, which belongs to the technical field of conductive material preparation. Background technique [0002] The drag reducing agent is composed of various components, including fine graphite, bentonite, curing agent, lubricant, conductive cement, etc., and is generally gray-black. It is a good conductor, and it is used between the grounding body and the soil. On the one hand, it can be in close contact with the metal grounding body to form a large enough current flow surface; on the other hand, it can penetrate into the surrounding soil and reduce the surrounding soil. Soil resistivity, forming a gently changing low-resistance area around the grounding body. At present, drag reducing agents are widely used in various fields of national economy. Such as electrical grounding devices in industries such as electric power, telecommunications, const...
