Description

technical field [0001] The invention relates to the technical field of electromagnetic radiation shielding appliances, in particular to conductive shielding shoes. At the same time, the invention also relates to a method for preparing conductive shielding shoes. Background technique [0002] With the development of electric power technology, live work in the electric power industry is becoming more and more frequent. Traditional live work shielding suits are composed of shielding hats, shielding jackets, shielding pants, and conductive shoes to form a "Faraday cage" to achieve the effect of shielding power plants. , The shielding hats, shielding jackets, and shielding pants used in reality are made of conductive shielding clothing fabrics, which have a "Faraday cage" shielding effect all day long. However, the current conductive shoes only conduct electricity on the sole, and the carbon black with low conductivity is used as the conductive material. The resistance is genera...
