Description
Technical Field
The invention relates to the technical field of electromagnetic radiation prevention shielding tools, in particular to a pair of conductive shielding shoes. Meanwhile, the invention also relates to a preparation method of the conductive shielding shoe.
Background
With the development of electric power technology, live working in the electric power industry is more frequent, the traditional live working shielding clothes are composed of shielding caps, shielding jackets, shielding trousers and conductive shoes, so that a Faraday cage is formed to achieve the effect of shielding a power plant, and the shielding caps, the shielding jackets and the shielding trousers used in reality are made of conductive shielding clothes fabrics and have the shielding effect of the Faraday cage all day. The existing conductive shoes only conduct electricity at soles, carbon black with low conductivity is adopted as an added conductive material, the resistance is generally between 400 and 500 omega, and the upper part is non-conductive, so that the shoe sole does not have a shielding function. Therefore, the whole shielding effect of the Faraday cage is not formed, the Faraday cage is a leak, great life safety hazards exist for operators who work with electrification, and particularly the current voltage level reaches 1000 kV.
The conductive shoe is an electric functional protective shoe, which is usually made by adding conductive components such as carbon powder and conductive fibers into shoe materials, and the resistance value of the conductive shoe is required to be 1.5 multiplied by 105 omega. When carbon powder is used as a conductive component, a large amount of carbon powder needs to be added to achieve the low resistance, the color of the product is limited to black due to the high addition amount of the carbon powder, and the problem is that dust falls off during the use of the product to pollute objects in contact with the conductive shoes. And because the particle size of the carbon powder is small, agglomeration is easy to occur in the mixing processing process, so that the raw material waste is large. Another method is to add conductive fibers into the shoe material, but in order to ensure the conductivity, the conductive fibers are required to have a considerable length and not to be broken during the processing process as much as possible, while the use of an excessively long conductive fiber size causes a serious reduction in the material flow coefficient, and a plug flow is formed during the injection molding of the shoe material. And because the length of the conductive fiber is larger, the fiber is easy to agglomerate and disperse unevenly in the mixing processing process of the fiber, the base material and the auxiliary agent, so that the resistance of the shoe material is greatly increased, and the conductivity is reduced. No matter the conductive shoes are manufactured by adopting carbon powder or conductive fibers as conductive components, the waste of raw materials is caused, and the large-scale production is difficult and the cost is high.
CN209573377U discloses a novel antistatic one-way conductive shoe, which comprises a vamp and a sole arranged below the vamp and made of insulating material, the sole comprises a wear-resistant sole with a containing cavity and an insole, a caulking groove is arranged at the front sole in the wear-resistant sole, a one-way conductive component is arranged in the caulking groove, the insole is laid in the containing cavity and covers the caulking groove, conductive cloth is arranged on the inner wall of the vamp and the top surface of the insole, a placing groove is arranged on the wear-resistant sole, a grounding carbon brush is arranged in the placing groove, the conductive cloth and the grounding carbon brush form series connection and fixation through the one-way conductive component, compared with the prior art, the invention realizes grounding connection by utilizing the grounding carbon brush, changes the form of the traditional conductive needle, improves the wearing comfort level, and simultaneously utilizes the one-way conductive component to lead the grounding carbon brush to discharge static charges generated by the surface area of a human body or other charges entering the human body in time, the elimination is completed and the introduction of ground leakage into the human body can be prevented.
CN102504440B discloses a conductive shoe material and a manufacturing method thereof, the conductive shoe material is made of a composite conductive component consisting of polyvinyl chloride, conductive fiber and conductive powder and an auxiliary agent; the composite conductive component is pretreated by stearic acid-coupling agent treatment solution. The manufacturing method comprises the following steps: (1) pretreatment: firstly, conducting fiber and conducting powder are pretreated by stearic acid-coupling agent treatment solution; (2) mixing: firstly, mixing polyvinyl chloride, plasticizer and stabilizer at high speed; then adding the composite conductive component pretreated by the foaming agent, the solubilizer and the stearic acid-coupling agent treatment solution for mixing; (3) extruding: extruding the mixed materials, and cutting to obtain granules; (4) injection molding: the material is injection molded by an injection molding machine at 160 ℃ to obtain the finished shoe material. The conductive shoe material has the advantages of uniform dispersion of conductive components, capability of forming an effective conductive network and low cost. The manufacturing method has simple process, large-scale production and low cost.
The upper parts of the above patent documents are all conductive and have a certain shielding function, but the conductive shielding function of CN209573377U needs to be further improved, and CN102504440B has more materials and relatively complex preparation process. Therefore, the conductive shielding shoes are developed, the whole shielding effect of the Faraday cage can be formed, the conductive shielding function is good, and the potential safety hazard of operators in live working is eliminated.
