摘要（英）：

The invention discloses a resistance reduction material for grounding engineering. The material comprises a conductive component group, an additive component group and a gelling component group, wherein the weight part ratio of the conductive component group to the gelling component group to the additive component group is 1:0.6:0.05; the conductive component group comprises the following components in percentage by weight: 65.0-77.0wt% of a high-conductivity carbon fiber with the diameter of 7 microns, the length of 1-2 mm and the purity of 95-99%, 14.0-20.0wt% of 325-400-mesh flake graphitepowder, 7-10.0wt% of 325-400-mesh aluminum chloride (AlCl3) and 2.0-5.0wt% of polyanionic cellulose (PAC); the additive component group comprises the following components in percentage by weight: 40-50% of sodium polystyrenesulfonate and 50-60% of polyacrylamide; and the gelling component group comprises the following components in percentage by weight: 50% of water glass with a modulus of 3.3 and50% of water. The material solves the problems that the graphite intercalation reaction temperature is high, the time is long, and the accumulation efficiency of conductive particles is low, so thatthe conductivity and the use durability of a product are improved.
