Preparation method of a flexible composite corrosion-resistant grounding material

Abstract

The invention discloses a preparation method for a flexible compound corrosion-resistant grounding material, and belongs to the technical field of grounding material preparation. According to the method, mixed reaction is carried out on iron powder, silicon powder and so on; the materials are prepared into a blank through hot rolling; wire drawing and annealing are carried out to obtain alloy fibers; mixed reaction is carried out on the alloy fibers, polyvinyl chloride resin, octadecylamine and so on; the alloy fibers are wrapped by resin; expanded graphite and coupling reagent are added to the alloy fibers wrapped by the resin, and stirring reaction is carried out; the resin is wrapped by the graphite; the resin wrapped by the graphite is rolled into the blank; the blank is cooled, is leached by alkaline and is washed by deionized water; mixed soaking is carried out on the purified blank, copper sulfate and absolute ethyl alcohol; and the finally processed blank is dried in the air, thereby preparing the flexible compound corrosion-resistant grounding material. According to the method, the preparation steps are simple; the alloy fibers are wrapped through full utilization of the resin; the flexible compound corrosion-resistant grounding material is prepared by wrapping the resin through the graphite; the pertinence is high; the corrosion-resistance and low flexibility problems are solved effectively; there is no corrosion phenomenon after the material is employed for 10-12 years; the obtained product is easy to transport and construct; the clearance between the product and soil is little; the cost is low; and the material is not liable to steal.

Description

technical field [0001] The invention relates to a method for preparing a flexible composite corrosion-resistant grounding material, which belongs to the technical field of grounding material preparation. Background technique [0002] Grounding is an important means to ensure the safety of electric power, communication, microelectronic equipment and other equipment, buildings and personal safety. With the advancement of electricity, microelectronics and cutting-edge science, the requirements for grounding systems are getting higher and higher. In recent years, equipment damage accidents caused by poor grounding systems have occurred frequently, especially in thunderstorm seasons, when the grounding device is corroded, which increases the grounding resistance and reduces the thermal stability of the grounding system, resulting in frequent equipment damage due to lightning strikes. occur. With the continuous increase of the capacity of the power system, the requirements for t...
