Abstract

he invention relates to a high-polymer-resin resistance-reducing agent and a preparation and use method thereof. The high-polymer-resin resistance-reducing agent comprises sodium nitrite, polyacrylamide, ammonium persulfate, methylene bisacrylamide and triethanolamine; and specifically, the parts are in a following proportion: 25 to 35% of polyacrylamide, 55 to 65% of sodium nitrite, 2 to 4% of triethanolamine, and 3 to 6% of methylene bisacrylamide. All parts are mixed based on a proportion and are stirred uniformly to make high-polymer-resin resistance-reducing agent powder. When the high-polymer-resin resistance-reducing agent is in use, the prepared high-polymer-resin resistance-reducing agent is dissolved by using clear water; after uniform stirring, the high-polymer-resin resistance-reducing agent liquid becomes sticky gradually; the sticky liquid is poured into a ground device; and then the high-polymer-resin resistance-reducing agent liquid is solidified. According to the invention, the high-polymer-resin resistance-reducing agent is stirred uniformly with water and becomes liquid; and then the liquid becomes gel; and the liquid high-polymer-resin resistance-reducing agentis placed on the ground device to generate a root effect in soil, so that the diffusion area of the ground device is increased equivalently.

Description

technical field [0001] The invention belongs to a chemical auxiliary agent and a preparation method thereof, in particular to a polymer resin drag-reducing agent and a preparation method thereof. It can be widely used in various industries for lightning protection and grounding places. Background technique [0002] The drag reducing agent is generally composed of various components, including fine graphite, bentonite, curing agent, lubricant, conductive cement, etc., and is generally gray-black. It is a good conductor, and it is used between the grounding body and the soil. On the one hand, it can be in close contact with the metal grounding body to form a large enough current flow surface; on the other hand, it can penetrate into the surrounding soil and reduce the surrounding soil. Soil resistivity, forming a gently changing low-resistance area around the grounding body. [0003] At present, drag reducing agents are widely used in various fields of national economy. It ...
