Description

Technical Field

[0001] The present invention relates to the field of high-voltage live working, and in particular to a conductive shielding shoe. Background Art

[0002] When working with high-voltage live wires, worker safety is paramount. With the continuous advancement of power technology, workers are increasingly performing live wire maintenance on live grid components, requiring them to wear shielding clothing to protect themselves from electromagnetic waves. The design principle of shielding clothing is based on the Faraday cage effect, which uses a closed metal surface to reduce the internal electric field to zero. However, existing shielding clothing and shielding shoes have many shortcomings in practical application.

[0003] For example, most existing shielding shoes only have conductive soles, while the uppers are non-conductive. This makes it impossible to form a complete Faraday shielding cage and cannot fully shield electromagnetic waves. This may cause electromagnetic waves to invade through the uppers, threatening the safety of workers. In addition, existing conductive shoes mostly use nylon thread sewing technology, which will cause bumps or unevenness on the shoe surface. The bumps are prone to charge accumulation, reducing the overall shielding efficiency. At the same time, large amounts of carbon powder or conductive fibers are added to the existing conductive sole materials. High amounts of carbon powder will cause dust to fall off, and when it enters the electric field along the insulator, it will contaminate the insulator, significantly reducing the insulation performance of the insulator. These problems seriously affect the safety and work efficiency of workers. Therefore, there is an urgent need for a conductive shielding shoe that can effectively solve the above problems.

[0004] In the prior art, for example, patent number CN111838862A discloses a conductive shielding shoe and a preparation method thereof. However, the conductive shielding shoe of this patent still has the following deficiencies: first, the conductive performance of the upper portion mainly depends on the metal conductive fiber yarn, which is easily degraded due to factors such as friction in actual use; second, the sole structure of this patent is relatively simple, and the conductive function is achieved only by mixing conductive silver-plated glass beads with plastic materials, which cannot effectively solve the problem of balancing the conductive performance, wear resistance, and insulation of the sole; finally, the connection method between the shoelaces and the upper of this patent is not clearly stated, and a complete Faraday cage cannot be formed; the suture thread ends are prone to accumulate charge; and the conductive sole material is prone to dust and contaminate the insulator.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0044] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise indicated, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0045] Example 1

[0046] The present invention relates to a conductive shielding shoe designed to address issues such as the inability of existing shielding shoes to form a complete Faraday cage, the tendency of suture threads to accumulate charge, and the tendency of conductive sole materials to shed dust and contaminate insulators. The following is a detailed description of specific embodiments of the present invention:

[0047] The conductive sole assembly 1 consists of a wear-resistant outer bottom layer 11, a conductive middle layer 12, and an insulating inner bottom layer 13. The wear-resistant outer bottom layer 11 is made of thermoplastic polyurethane elastomer (TPU), which has excellent mechanical strength, wear resistance, oil resistance, and flexibility, and is particularly suitable for use in high-voltage live working environments. The conductive middle layer 12 is composed of a natural rubber nanocomposite material reinforced with carbon nanotubes (CNTs). This is achieved by ultrasonically dispersing multi-walled carbon nanotubes in an organic solvent to form a suspension, mixing and homogenizing it with a natural rubber solution and a vulcanizing additive, and then forming a composite film using a vacuum casting process. The composite film is then subjected to a multi-stage vulcanization treatment at a preset temperature and pressure to obtain a conductive rubber composite material with a continuous conductive mesh structure. The insulating inner bottom layer 13 is made of a non-conductive elastic material, such as natural rubber, and is used to isolate the wearer's foot from the conductive middle layer 12 to avoid direct contact while providing good comfort.

[0048] Conductive upper component 2 is made of Ti3C2T X The coated fabric is formed by etching Ti3AlC2 powder through a mixed acid solution to obtain a single layer of Ti3C2T X The fiber substrate is then impregnated with Ti3C2T X In the dispersion, a gradient drying process forms an alternating stack of nanosheets on the fiber surface. This coated fabric exhibits high conductivity and excellent flexibility, effectively shielding electromagnetic waves and reducing charge accumulation. The bottom of the conductive upper component 2 and the conductive intermediate layer 12 form a closed conductive path through a non-stitched conductive connection structure, preventing charge accumulation at the ends of stitching, which could reduce shielding efficiency and endanger personnel safety.

[0049] Integrated conductive shoelaces 3 made of Ti3C2T X The coated fabric is woven and directly contacts the conductive upper component 2. This not only increases the conductive material coverage of the upper, but also further enhances the electromagnetic shielding capability of the shielding shoe. X The coated fabric shoelaces can ensure the conductivity of the entire shoe body and form a complete Faraday cage shielding structure.

[0050] The heel connection component 4 comprises a detachable metal conductor. One end of the conductor is embedded in the conductive intermediate layer 12 and electrically connected to the conductive upper assembly 2. The other end features an interface for conductive connection to the shielding suit. This allows the shielding shoe and the suit to form a Faraday cage, protecting personnel. Adaptive, deformable conductive contacts are mounted on the metal conductor. These contacts, through a magnetic mounting base, form a dynamic equipotential connection with the conductive webbing at the hem of the suit, ensuring a consistent electrical connection between the shoe and suit during operation.

[0051] The preparation method of the conductive intermediate layer 12 specifically includes the following steps:

[0052] The multi-walled carbon nanotubes are dispersed in an organic solvent at an ultrasonic power of 600-900 W for 8-12 minutes to form a suspension with a concentration of 0.3-0.7 wt %.

[0053] The suspension is mixed with a natural rubber solution and a vulcanization additive, wherein the vulcanization additive comprises 4-6 phr of zinc oxide, 2-4 phr of sulfur, 0.5-1.5 phr of stearic acid and 0.5-1.2 phr of accelerator CBS.

[0054] The mixed solution was injected into the mold by vacuum casting process, dried under ambient conditions for 10-14 hours, and the solvent evaporation rate was monitored by infrared spectroscopy to be ≥99%.

[0055] The dried composite membrane material is subjected to a multi-stage vulcanization treatment, including:

[0056] High pressure hot vulcanization is carried out at a temperature range of 120-150°C and a pressure of 25-35 kN, with a treatment time of 50-70 minutes.

[0057] Post-curing treatment is carried out at a temperature of 80-110°C for 0.5-2 hours.

[0058] The mass ratio of the vulcanization additive to the natural rubber solution is 5-15 phr, and the mass fraction of the carbon nanotubes is 0.5-5%.

[0059] Ti3C2T X The preparation method of the coated fabric specifically comprises the following steps:

[0060] Ti3AlC2 powder is reacted with a mixed acid solution at a solid-liquid ratio of 3g:60mL. The mixed acid solution is prepared by mixing 10-12M hydrochloric acid, deionized water and 40-50% hydrofluoric acid in a volume ratio of 5:3:1 to 7:3:1. The mixture is stirred and etched at 30-40°C for 20-30 hours to obtain an etched product.

[0061] The etched product was washed with deionized water to a pH of 6-7 and separated by centrifugation to obtain a single-layer Ti3C2T X The centrifugal speed is 3000-5000 rpm, and the centrifugation time is 3-10 minutes each time.

[0062] The cotton / linen blended fabric was washed with industrial detergent and then immersed in Ti3C2T X In the dispersion, the diameter of a single layer of flakes is 200-400 nm, the dipping time is 0.5-2 minutes each time, and an alternately stacked nano-sheet structure is formed on the fiber surface through a gradient drying process.

[0063] The gradient drying process includes segmented temperature-controlled drying, with each segment increasing in temperature by 3-8°C and a coating loading of 10-20 mg / cm 2 .

[0064] To further enhance the performance of the conductive sole assembly 1, the bottom surface of the wear-resistant outer layer 11 is equipped with anti-slip textures and drainage channels, enhancing the sole's anti-slip and drainage capabilities. The insulating inner layer 13 is physically secured to the conductive middle layer 12, and an array of anti-slip protrusions on the inner sole surface provide enhanced comfort and anti-slip properties.

[0065] The interface between the conductive upper component 2 and the conductive sole component 1 features a transition structure consisting of alternating conductive fiber woven layers and elastic cushioning layers, with the density of the conductive fibers increasing along the depth of the joint. This not only strengthens the connection between the upper and sole, but also further enhances conductivity and overall shielding effectiveness.

[0066] The metal conductor surface of the heel connector 4 is equipped with adaptively deformable conductive contacts, which form a dynamic equipotential connection with the conductive webbing of the shielding suit's trouser legs via a magnetic mounting base. This ensures a consistent electrical connection between the shoe and the shielding suit during operation, forming a complete Faraday cage shielding structure and protecting the operator's safety.

[0067] Conductive shielding shoes and shielding clothing form a complete Faraday cage system. The conductive middle layer of the shoe body is 12, and the upper is Ti3C2T X The coating and heel connector 4 are connected to the conductive layer of the shielding suit through multiple points of contact, forming a closed equipotential shielding network. This not only improves shielding efficiency and enhances operator safety, but also reduces contamination to insulators, resulting in excellent economic benefits and practical application value.

[0068] Through the above-mentioned embodiments, the conductive shielding shoes of the present invention can effectively protect the safety of workers during high-voltage live operations, improve shielding efficiency, and reduce charge accumulation and dust drop.

[0069] Example 2

[0070] As a specific example of the above example, the purpose of this patent is to provide a conductive shielding shoe. By processing and using conductive rubber and fabric materials, a shielding shoe with a conductive upper and sole is designed. This shielding shoe is comfortable and wear-resistant while also being conductive and can prevent the accumulation of charge formed by the protruding seams of the shoe body. This solves the problem of shielding clothing not providing enough protection for the human foot, reduces the contamination of insulators by dust, improves the shielding efficiency of shielding clothing, and enhances the safety of workers working with live lines.

[0071] Preparation method of conductive natural rubber nanocomposite material:

[0072] Conductive natural rubber (NR) nanocomposites were prepared by solvent casting a suspension of reduced carbon nanotubes (CNTs) and subsequently vulcanizing the rubber composite.

[0073] CNT suspension preparation: Multi-walled CNTs (approximately 40 μm in length, 20 nm in thickness, and 8 nm in wall thickness) were dispersed into toluene by ultrasound using an ultrasonic probe with a 6 mm tip at a maximum power of 750 W for 10 minutes. The final CNT concentration in the solvent was adjusted to 0.5 wt%.

[0074] The curing additives were: 5 phr ZnO, 3 phr sulfur, 1 phr stearic acid, and 0.8 phr CBS, equivalent to 4.6 wt% ZnO, 2.7 wt% sulfur, 0.9 wt% stearic acid, and 0.7 wt% CBS, respectively, relative to the amount of NR used. The proportion of the carbonaceous phase in the final composition was adjusted by adding different amounts of a solution containing 0.5 wt% CNTs.

[0075] Composite Preparation Method: Solvent-based CNTs were mixed with NR solution and the desired additives for vulcanization. The mixture was homogenized for 5 minutes at 5000 rpm using a homogenizer, followed by sonication in a conventional ultrasonic bath for 5 minutes. The solution was poured into a square glass mold and dried under ambient conditions for 12 hours. Infrared IR spectroscopy was used to monitor and confirm complete evaporation of all solvents prior to vulcanization. Uniform solvent evaporation produced a conductive rubber composite film. The film was rolled from the mold and vulcanized for 1 hour using a hot press at 145°C and 30 kN of pressure.

[0076] The shielded shoe sole consists of three layers.

[0077] The wear-resistant outer layer 11 of the conductive sole assembly 1 is composed of thermoplastic polyurethane (TPU), a linear polymer material produced by the reaction of diisocyanate, macromolecular polyol, and chain extender. It is a novel, environmentally friendly material with excellent mechanical strength, wear resistance, oil resistance, and flexibility, with wear resistance being particularly prominent.

[0078] The conductive middle layer 12 is composed of the above-mentioned conductive natural rubber nanocomposite material. The midsole is connected to the conductive upper of the shielding shoe to form a conductive path and a Faraday cage to protect the feet of the wearer.

[0079] The insulating inner bottom layer 13 is an insole made of natural rubber, which isolates the wearer's feet from the conductive midsole to avoid direct contact.

[0080] The soles of shielded shoes have good comfort and wear resistance. On the premise of having good conductivity, they not only provide protection for the feet, but also prevent dust from falling and contaminating the insulators.

[0081] Preparation method of highly conductive Ti3C2Tx coated fabric:

[0082] Single-layer Ti3C2Tx synthesis method: Ti3C2T X It was synthesized from aluminum-rich Ti3AlC2 by a mixed acid method. 3 g of Ti3AlC2 powder with a particle size of less than 32 μm was slowly added to 60 ml of an etching solution containing 36 ml of 12M hydrochloric acid HCl, Fisher Chemical, 37%, 18 ml of deionized DI water, and 6 ml of 49% hydrofluoric acid HF, Acros Organics. The mixture was stirred at 600 rpm with a magnetic stir bar at 35°C for 24 hours. After etching, the multilayer Ti3C2T was washed with DI water. X , and repeat the centrifugation for 5 minutes until the pH reaches 6-7.

[0083] Ti3C2T X Preparation of coated fabrics: Raw cotton and linen woven fabrics were washed with industrial strength liquid detergent to remove impurities. Fabric samples were immersed in a 15 mg / ml concentration of additive-free aqueous Ti3C2T X Dye for 1 min, then air dry, and repeat this process until the desired loading is achieved.

[0084] The conductive upper component 2 is covered by the aforementioned Ti3C2Tx coated fabric, and the bottom of the conductive upper component 2 is connected to the conductive intermediate layer 12 to form a conductive path.

[0085] The integrated conductive shoelace 3 is made of Ti3C2Tx coated fabric, which further enhances the conductive material coverage of the shoe upper and the electromagnetic shielding capability of the shielding shoe.

[0086] The heel connecting component 4 is provided with a detachable metal conductor, which can be a metal connector. The lower part of the metal connector is connected to the conductive sole and the upper, and the upper part can be connected to the pants, forming a Faraday cage with the shielding suit as a whole to protect the safety of personnel.

[0087] The sole thickness is about 3cm, which has a certain degree of comfort and wear resistance, improving the convenience and safety of operation.

[0088] The connection between the sole and the upper of the shielding shoes is adhesive to avoid the accumulation of electric charges at the stitching ends, which will reduce the shielding efficiency and endanger personnel safety.

[0089] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
