Abstract

The invention relates to the technical field of grounding resistance-reducing materials in the fields of electric power, transportation, petroleum, petrochemicals and the like, in particular to a novel polymer skeleton resistance-reducing agent, which is a novel physical resistance-reducing agent, namely a graphite-based physical resistance-reducing material, with a novel water-based polymer material skeleton structure and is suitable for the resistance reduction requirements of a grounding material, a grounding grid and a lightning protection grounding system in the fields of petroleum, petrochemicals, electric power, buildings and the like. The novel polymer skeleton resistance-reducing agent is prepared from the following raw materials in part ratios by weight: 10%-30% of a water-soluble polymer skeleton, 10%-30% of a water-retaining agent, 40%-80% of a diffusing conductive agent and 0.5%-2% of an assistant. The novel polymer skeleton resistance-reducing agent has a solid space structure; the overall spatial density of the resistance-reducing agent is improved; combination of the inside of the resistance-reducing agent, the resistance-reducing agent and soil is tighter; the diffusing effect of the resistance-reducing agent is improved; the bulk conductivity and the grounding resistance of the resistance-reducing agent can also be improved; and the effect of reducing the grounding resistance of the grounding material in a high-resistivity soil region is achieved.

Description

technical field [0001] The present invention relates to the technical field of grounding resistance-reducing materials in the fields of electric power, transportation, petroleum and petrochemicals, etc., and in particular to a novel polymer framework resistance-reducing agent, which is a new type of physical resistance-reducing agent with a novel water-based polymer material skeleton structure— —Graphite-based physical resistance-reducing material. It is suitable for the resistance reduction requirements of grounding materials, grounding grids, lightning protection grounding systems, etc. in petroleum, petrochemical, electric power, construction and other fields. Background technique [0002] Grounding is an important means to ensure the safety of electric power, communication, microelectronics and other equipment, buildings and personal safety. A reliable ground should have a low ground resistance value. And the grounding resistance does not change too much with the runni...
