Problems solved by technology

Chinese patent ZL201120438767.4 discloses a self-rolling sleeve, that is, it is self-curling along the radial direction of the sleeve so that the parts overlap each other and can be opened under the action of external force, but the sleeve only serves to simply protect the cables and It is convenient for construction, and has no anti-puncture and shielding performance
Chinese patent ZL201310584056.1 uses PET monofilament, PA monofilament or PPS monofilament and axial metal wire to weave into warp and weft to form a self-rolling sleeve. The sleeve has a shielding effect, but the fabric woven with metal wire is easy to break in the axial direction , the formed broken end is easy to damage the internal protected pipeline; and there are problems such as light aging resistance, high temperature resistance and puncture resistance.

Embodiment 1

[0054] Preparation of the self-rolling sleeve layer:

[0055] The warp yarn is composed of 5 strands of non-thermoplastic polyimide organic fiber with a linear density of 600D and combined at constant tension. The weft yarn is a single thermoplastic polyimide organic fiber monofilament with a monofilament diameter of 0.50mm, which is woven into a plain weave tape in warp and weft. At the same time, a free edge along the warp direction is woven with 2 strands of white aramid organic fiber with a maximum diameter marking line, and the shortest distance between the marking line and the free edge of the warp is 7mm. Wherein, the warp yarn has a weaving density of 30 strands / inch, and the weft yarn has a weaving density of 30 strands / inch.

[0056] The woven sheet-like woven fabric is passed through the treatment tank with a solid content of 15% anti-mold liquid (anti-mold agent GN-A626, purchased from Dongguan Guangneng Shoe Material Co., Ltd., the same below) at a speed of 2m / min...

[0064] Preparation of the self-rolling sleeve layer:

[0065] The warp yarn is composed of 3 strands of aramid organic fiber with a multifilament linear density of 1000D at constant tension, and the weft yarn is 2 strands of polyphenylene sulfide organic fiber monofilament with a monofilament diameter of 0.20mm and 3 strands of 20 polyimide yarns. The plain weave belt structure is formed into warp and weft. At the same time, a free edge along the warp direction is woven with 2 strands of white aramid organic fiber with a maximum diameter marking line. The shortest distance between the marking line and the free edge of the warp is 7mm. Wherein, the weaving density of the warp yarn is 25 strands / inch, and the weaving density of the weft yarn is 25 strands / inch.

[0066] The woven sheet-shaped woven fabric is passed through the treatment tank with a solid content of 20% mildew-proof liquid at a speed of 2m / min, the drying hot roller at 200°C, and the treatment tank with a solid c...

Embodiment 3

[0073] Preparation of the self-rolling sleeve layer:

[0074] The warp yarn is composed of 8 strands of multifilament linear density 1200D polybenzoxazole organic fiber with constant tension, the weft yarn is 1 thermoplastic polyimide organic fiber monofilament with a monofilament diameter of 0.60mm and 5 strands of 15 non-thermoplastic polyimide Amine yarn, woven into a warp and weft twill weave tape structure, and a free edge along the warp direction is woven with a maximum diameter marking line with 2 strands of white aramid organic fiber, and the shortest distance between the marking line and the free edge of the warp is 10mm. Wherein, the weaving density of the warp yarn is 20 strands / inch, and the weaving density of the weft yarn is 20 strands / inch.

[0075] The woven sheet-like woven fabric is sequentially passed through a treatment tank with a solid content of 30% mold-proof liquid at a speed of 8m / min, a drying hot roller at 280°C, and a treatment tank with a solid co...

Abstract

The invention relates to a self-rolling shielding sleeve with a three-layer structure. The self-rolling shielding sleeve comprises a self-rolling sleeve body layer, a metal tape layer and an adhesive layer. Among them, the self-rolling sleeve layer is formed by a sheet-like woven fabric, which is self-curled into a curled state in which the relative free sides overlap each other without external force; the metal belt layer is formed by a plurality of metal belts; the adhesive layer is made of a polymer film form. A layer of metal tape is located between the self-wrapping sleeve layer and the adhesive layer. The invention also relates to a method for the preparation of said sleeve. The bushing of the present invention has the following advantages: excellent shielding effect, can prevent broken metal wires from scratching the protected object, and also has excellent light aging resistance, high temperature resistance, mildew and water resistance and puncture resistance, and is especially suitable for Protect cables, optical cables and other tubular objects under harsh environmental conditions such as high temperature, high radiation intensity, and large electromagnetic signal interference.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a self-rolling shielding sleeve with a three-layer structure and a preparation method thereof. Background technique [0002] Braided protective sleeves are widely used in the protection of tubular objects, such as wire harnesses and cables in the fields of automobiles, ships, and aerospace. Chinese patent ZL201120438767.4 discloses a self-rolling sleeve, that is, it is self-curling along the radial direction of the sleeve so that the parts overlap each other and can be opened under the action of external force, but the sleeve only serves to simply protect the cables and It is convenient for construction, and has no anti-puncture and shielding properties. At present, the number of wiring harnesses inside machines in various fields is increasing day by day, and there is an urgent need for protective sleeves with shielding functions to prevent signals from interfering with ea...
