Preparation method of high-water-retaining property bentonite resistance reducing agent

Abstract

The invention belongs to a preparation method of a high-water-retaining property bentonite resistance reducing agent. In order to solve the problems that resistance reduction is difficult and a resistance reducing effect cannot last in a high-soil resistivity region, the method comprises the following steps of: preparing activated calcium-base bentonite serving as a main material of the resistance reducing agent by employing a bentonite activation modification technology; preparing the high water-retaining property bentonite resistance reducing agent by using materials such as sodium polyacrylate water absorbent resin, a compound multi-metal general gas-phase corrosion inhibitor, sodium chloride and clay; and carrying out special combined packaging on the resistance reducing agent. The high-water-retaining property bentonite resistance reducing agent prepared by the method can be applied to a lightning protection and electric grounding system and laid around a grounding body, and the grounding resistance of the grounding body is reduced by increasing the equivalent area of the grounding body, reducing contact resistance between the grounding body and surrounding soil and improving and keeping the conductive property of the surrounding soil of the grounding body for a long time.

AI Technical Summary

Problems solved by technology

[0004] In areas with high soil resistivity, especially in mountainous areas, the water retention capacity of the soil is very poor, making it difficult for the grounding resistance of the grounding system to meet the standard requirements

To reduce the grounding resistance, there are difficulties such as large amount of construction, insignificant resistance reduction effect and not lasting
