Graphite cloth and production method thereof

Abstract

The invention relates to the technical field of graphite resistance-reducing cloth, in particular to graphite cloth and a production method thereof. The method comprises the steps that expandable graphite is expanded at high temperature to obtain graphite worms, the graphite worms are rolled through rolling equipment to obtain an inner graphite layer and an outer graphite layer, a fiber layer is infiltrated with a binder, and the binder is heated and cured to form a bonding layer; the fiber layer is bonded on the end face of one side of the inner graphite layer, then the outer graphite layer is laid on the surface of the inner graphite layer, the graphite composite material is turned over after being rolled twice, the other side of the inner graphite layer is covered with the fiber layer and the outer graphite layer in the same mode, and the conductive low-resistance graphite paper is formed after being rolled twice. The graphite composite resistance-reducing cloth with a smooth and flat surface, high compactness and good performance is obtained by cutting, twisting, weaving and shaping the conductive low-resistance graphite paper, the conductivity and the resistance-reducing effect of the graphite resistance-reducing cloth are effectively enhanced through the method, the corrosion resistance, the flexibility and the ground-attaching performance of the graphite resistance-reducing cloth are greatly improved, and the service life of the graphite resistance-reducing cloth is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of graphite resistance-reducing cloth, in particular to a graphite cloth and a production method thereof. Background technique [0002] It is an important facility to ensure the safety and stability of the power system and the personal safety of electric power construction personnel. The resistance reducing agent and grounding module as auxiliary grounding materials can effectively ensure the safe and stable operation of electrical equipment and the personal safety of operators in some areas with high soil resistivity . [0003] However, the drag-reducing effect of the drag-reducing agent is unstable, and its drag-reducing effect gradually weakens with the passage of time and the flow of groundwater. In addition, the chemical substances contained in the lost drag-reducing agent will pollute the nearby soil and groundwater, so it can replace the Graphite resistance-reducing cloth with long-term resistance-re...

[0003] However, the drag-reducing effect of the drag-reducing agent is unstable, and its drag-reducing effect gradually weakens with the passage of time and the flow of groundwater. In addition, the chemical substances contained in the lost drag-reducing agent will pollute the nearby soil and groundwater, so it can replace the Graphite resistance-reducing cloth with long-term resistance-reducing effect and no loss has become a better resistance-reducing material. The existing graphite resistance-reducing cloth is not flexible enough to fit closely with the ground, and its resistance-reducing strength is not high. good
