Problems solved by technology

The outer protective layer is easy to attract rats and rodents to chew on their teeth due to the smell of plastic or plastic, exposing the internal conductors, which is easy to cause cable or cable breakage, resulting in line interruption and other problems
[0003] At present, there are two main methods to prevent mice from eating cables. One is to directly add strong irritating substances such as capsaicin during the processing of the cable sheath to prevent animals from biting, but adding capsaicin during the processing Such strong irritating substances will increase the protection requirements of the factory workshop and increase the cost
The second is to open holes inside the cable and place rodent repellent and other substances, but the mouse may not eat to the place where the medicine is placed during the feeding process, or the internal wire core is exposed when the mouse eats the protective layer, and there is still a danger.

Embodiment 1

[0029] The wire includes a core 1 and a shielding layer 2 wound outside the core 1. An aluminum-plastic composite tape can be used as the shielding layer 2. The shielding layer 2 is wrapped with a skeleton 3. The skeleton 3 is a ring-shaped bracket with convex strips on it. It plays the role of support and cushioning. The gaps of the frame 3 are filled with an anti-gnawing layer 4 for preventing mice from gnawing. The frame 3 is wrapped with an extrusion belt 5. The tip of the pressing boss faces the wire core 1 and penetrates into the anti-gnawing layer 4. The extrusion belt 5 is wrapped with a protective sleeve 6. The extrusion belt 5 is provided with a plurality of release holes 51 for releasing the inside of the anti-gnawing layer 4. The rodent repelling substance, the skeleton 3 and the extruded belt 5 can be made of resin.

Embodiment 2

[0031] The invention also discloses a preparation method of the anti-gnawing layer, and the specific preparation steps are as follows:

[0032] A solution raw material: 200g polyester polyol, 10g dibutyltin dilaurate, 500g water; B solution raw material: 1396.72g polyester polyol, 698.36g diphenylmethane diisocyanate, 34.92g dibutyltin dilaurate; 71g organic Silicone oil, 28.4g camphor oil, 568g rat repelling particles.

[0033] (1) Dry the cleaned sage orchid roots and cleats horn roots in the sun, mix them according to the mass ratio of 2:1 after drying, and then pulverize them into micropowders with a size of about 50 μm for use;

[0034] (2) Crush the expanded perlite into granules, select the expanded perlite with a particle size of 0.5-0.8mm, heat it to 900°C at a temperature of 10°C / min, take it out after keeping it warm for 15min, and add the prepared product in step (1) after cooling to room temperature. The micropowder that obtains, wherein expanded perlite: the mas...

Embodiment 3

[0037] The invention also discloses a preparation method of the anti-gnawing layer, and the specific preparation steps are as follows:

[0038]A solution raw material: 100g polyester polyol, 5g dibutyltin dilaurate, 250g water; B solution raw material: 744.92g polyester polyol, 372.46g diphenylmethane diisocyanate, 18.62g dibutyltin dilaurate; 35.5g Silicone oil, 14.91g camphor oil, 298.2g rodent repelling particles.

[0039] (1) Dry the cleaned sage orchid roots and cleats horn roots in the sun, mix them according to the mass ratio of 2:1 after drying, and then pulverize them into micropowders with a size of about 50 μm for use;

[0040] (2) Crush the expanded perlite into granules, select the expanded perlite with a particle size of 0.5-0.8 mm, heat it to 1000 °C at a temperature of 10 °C / min, take it out after keeping it for 10 min, and add the prepared product in step (1) after cooling to room temperature. The micropowder that obtains, wherein expanded perlite: the mass r...

Abstract

The invention discloses a novel wire rod based on electronic information transmission, and belongs to the technical field of wire rods, the wire rod comprises a wire core and a shielding layer wound outside the wire core, the shielding layer is wrapped by a skeleton, gaps of the skeleton are filled with an anti-gnawing layer, the skeleton is wrapped by an extrusion belt, and the extrusion belt is wrapped by a rubber belt. The inner surface of the extrusion belt is provided with an extrusion boss, the tip end of the extrusion boss faces the wire core and penetrates into the anti-gnawing layer, the extrusion belt is wrapped with a protective sleeve, and the mechanical performance is not reduced while rodents are effectively prevented from gnawing.

Description

technical field [0001] The invention relates to the technical field of wire rods, in particular to a novel wire rod based on electronic information transmission. Background technique [0002] Electronic wires, generally belonging to weak current projects, are used in telephone communication systems, computer LAN systems, cable TV signal distribution systems, video, alarm systems and other industries closely related to residents such as construction, public security, post and telecommunications, radio and television, fire protection, and electrical industries. , Common such as communication cables, data cables, etc. Cables often include two parts: the conductor as the cable core and the protective layer covering the outside of the conductor. The protective layer includes packaging materials, shielding layers, sheaths and other structures. The protective layer covering the outside of the conductor is not easy to bend the cable. Requirements such as rupture, usually made of fl...
