Through the coordinated design of the radiation protection layer and the antioxidant breathable film, when the coated cloth is used, the silver fiber in the silver ion woven layer in the radiation protection layer is a high-tech product obtained by permanently combining a layer of pure silver on the fiber surface through special technology.

At the same time, several groups of semicircular blocks reduce the contact area between the cloth and water droplets, so that the adsorption force of the cloth on water is much smaller than the surface tension of water, thereby improving the waterproof performance of the coated cloth.

DETAILED DESCRIPTION

[0021] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Example

[0023] like Figures 1 to 5 As shown, a radiation-proof and anti-penetration coated cloth comprises: a base fabric layer 1, a radiation-proof layer 2 is arranged on the upper surface of the base fabric layer 1, an anti-radiation layer 2 is arranged on the upper surface of the radiation-proof layer 2, an anti-ultraviolet layer 3 is arranged on the upper surface of the anti-ultraviolet layer 3, a wear-resistant layer 4 is arranged on the upper and lower sides of the radiation-proof layer 2, and the anti-oxidation breathable film 5 is arranged on the upper and lower sides of the radiation-proof layer 2, and the anti-oxidation breathable film 5 is a PTFE microporous film.

[0024] The base fabric layer 1 includes warp yarns 101 and weft yarns 102. The number of warp yarns 101 and weft yarns 102 are both several groups. The several groups of warp yarns 101 and weft yarns 102 are distributed perpendicular to each other, and the warp yarns 101 and weft yarns 102 are woven into a mesh structure. The warp yarns 101 and weft yarns 102 are woven into a mesh base fabric layer 1. Under the condition of ensuring the strength and toughness of the coated cloth itself, the mesh base fabric layer 1 is easier to penetrate when glue is used for compounding, so that the adhesion between the layers is stronger and the connection is tighter.

[0025] The anti-radiation layer 2 includes a silver ion woven layer 201 and an anti-static structure 202. The anti-static structure 202 includes a metal strip 203 and a metal anti-radiation disc 204. The metal anti-radiation disc 204 is equidistantly arrayed on the upper surface of the silver ion woven layer 201. The silver fiber in the silver ion woven layer 201 is a high-tech product obtained by permanently combining a layer of pure silver on the fiber surface through a special technology. This structure not only allows the silver fiber to maintain its original textile properties, but also gives it all the anti-radiation functions of silver. Silver has good electrical conductivity, which is several times or even hundreds of times that of ordinary conductive metals. Fabrics woven with silver fibers are excellent materials for shielding electromagnetic radiation.

[0026] The metal strips 203 are provided in several groups, and the several groups of metal strips 203 are distributed in a ring array on the outer circle of the metal anti-radiation disc 204. The metal strips 203 and the metal anti-radiation disc 204 are both highly conductive, which assists the silver ion woven layer 201 in playing the role of radiation protection and anti-static, thereby further enhancing the radiation protection capability.

[0027] The anti-ultraviolet layer 3 is woven from anti-ultraviolet fibers, which are woven from anti-ultraviolet copolymers. During outdoor activities, when ultraviolet rays are strong, the anti-ultraviolet layer 3 can also effectively block ultraviolet rays.

[0028] The wear-resistant layer 4 includes a thread layer 401 and a semicircular block 402. The thread layer 401 is woven from threads, which are composed of metal wires and nylon threads wound together. The semicircular block 402 is bonded to the outer surface of the thread layer 401 by adhesive. The metal wires and nylon threads are wound together, which are wear-resistant to a certain extent and improve the wear-resistant effect. The semicircular block 402 is directly worn on the surface of the coated cloth, thereby improving the wear resistance of the coated cloth surface.

[0029] Several groups of semicircular blocks 402 are provided, and gap grooves 403 are formed between the several groups of semicircular blocks 402. The bottom of the gap grooves 403 is filled with waterproof coating 404, and the waterproof coating 404 is a water-soluble resin waterproofing agent. Several groups of semicircular blocks 402 reduce the contact area between the cloth and water droplets, so that the adsorption force of the cloth on water is much smaller than the surface tension of water, thereby improving the waterproof performance of the coated cloth. At the same time, the waterproof coating 404 is filled on the gap grooves 403 between the semicircular blocks 402, so that the water droplets can only contact the semicircular blocks 402, and the water droplets can be shaken off by shaking, and cannot invade the gap grooves 403, effectively preventing the water droplets from penetrating into the interior of the coated cloth, further improving the waterproof performance of the coated cloth.

[0030] Implementation scheme: The silver fiber in the silver ion woven layer 201 in the radiation protection layer 2 is a high-tech product obtained by permanently combining a layer of pure silver on the fiber surface through a special technology. This structure not only allows the silver fiber to maintain its original textile properties, but also gives it all the radiation protection functions of silver. Silver has good electrical conductivity, so that the coated cloth can effectively shield electromagnetic radiation. The antioxidant breathable film 5 on the upper and lower sides of the radiation protection layer 2 is a PTFE microporous membrane, which has dust and water proof, breathable pressure relief, microporous exhaust, and UV resistance functions. It is physiologically inert and harmless to the human body, and has good antioxidant and high temperature corrosion resistance, thereby enhancing the antioxidant performance of the silver ion woven layer 201. The metal strip 203 and the metal anti-radiation disc 204 are both highly conductive, which assist the silver ion woven layer 201 in playing a role in radiation protection and anti-static, thereby further enhancing the radiation protection ability of the coated cloth. During outdoor activities, the ultraviolet rays are strong, and the anti-ultraviolet layer 3 can also effectively block ultraviolet rays. The wear-resistant layer 4 is composed of the silk thread layer 401 and the semicircular block 402. The middle silk thread layer 401 is woven from silk threads, and the silk threads are wound with metal wires and nylon threads, which are wear-resistant to a certain extent and improve the wear-resistant effect. The semicircular blocks 402 are directly worn on the surface of the coated cloth, thereby improving the wear resistance of the coated cloth surface. At the same time, several groups of semicircular blocks 402 reduce the contact area between the cloth and the water droplets, so that the adsorption force of the cloth on water is much smaller than the surface tension of water, thereby improving the waterproof performance of the coated cloth. At the same time, the gap grooves 403 between the semicircular blocks 402 are filled with waterproof coating 404, so that the water droplets can only contact the semicircular blocks 402, and the water droplets can be shaken off by shaking, and cannot invade the gap grooves 403, effectively preventing the water droplets from penetrating into the inside of the coated cloth, further improving the waterproof performance of the coated cloth, and the whole operation process is simple and convenient. Compared with the existing cloth, the utility model can improve the overall radiation protection and waterproof and anti-penetration effect of the coated cloth through design, effectively prolong its oxidation life while preventing radiation, and at the same time, the wear resistance of the coated cloth is improved, so that its service life is further improved.
