Abstract

The invention discloses a sulfonated polyaniline modified sodium bentonite resistance-reducing agent, which is mainly formed by mixing sodium bentonite, carbon fiber, graphene, carbon black, zinc powder, nickel powder, aniline, ammonium persulfate, metanilic acid, ammonium chloride, calcium oxide, sodium polyphosphate, sodium benzoate, cement and a retarder. By preparation at normal temperatures and pressures, dust is not easy to generate, and the product is soluble in water, contains no toxic or harmful substances. Environmental influence is little, construction is simple and convenient, and cost is low. The prepared resistance-reducing agent has low electrical resistivity, good corrosion resistance, good stability and good water-retaining property, is suitable for acidic and alkaline soil, sand, mountainous areas, rocky areas and the like where electrical resistivity is high and water content is easy to change, especially for soil with high electrical resistivity and acidic areas.

Description

technical field [0001] The invention discloses a sulfonated polyaniline modified sodium bentonite-based drag reducing agent, mainly relates to a high-efficiency physical drag reducing agent used for grounding projects such as electric grounding and lightning protection grounding, and belongs to the technical field of conductive grounding materials. technical background [0002] Resistance reducing agent is an engineering material widely used in the fields of power grounding and lightning protection grounding, especially in areas with high grounding resistance, it has good resistance reducing and anti-corrosion effects. [0003] In order to solve the problems that the early chemical drag reducers were easy to lose and the effective conductive components could not exist stably, a conductive polymer organic chemical drag reducer was developed. Conductive polymer organic chemical drag reducers overcome the disadvantage of easy loss of conductive components, but the corrosion of ...
