Description

Technical Field

[0001] The present invention relates to the technical field of wire materials, and in particular to a wire material based on electronic information transmission. Background Art

[0002] Electronic wires are generally used in weak current engineering and are used in telephone communication systems, computer LAN systems, cable TV signal distribution systems, video and alarm systems, and other industries closely related to residents, such as construction, public security, post and telecommunications, radio and television, fire protection, and electricity. Common examples include communication cables and data cables. Cables often include a conductor as a cable core and a protective layer wrapped around the outside of the conductor. The protective layer includes packaging materials, shielding layers, sheaths and other structures. The protective layer wrapped around the outside of the conductor is usually made of flexible materials to meet the requirements that the cable is not easily broken when bent. The outer protective layer emits a plastic or plastic smell, which easily attracts rodents such as mice to gnaw and mollusks, exposing the internal conductor, which can easily cause the cable or cable to break, leading to line interruption and other problems.

[0003] At present, there are two main methods to prevent rats from gnawing on cables. One is to directly add highly irritating substances such as capsaicin during the processing of the cable sheath to prevent animals from gnawing. However, adding highly irritating substances such as capsaicin during the processing will increase the protection requirements of the factory workshop and increase costs. The second is to open holes inside the cable and place substances such as rat repellent. However, rats may not gnaw to the location where the drugs are placed during the gnawing process, or the internal wire core is exposed when the rats have finished gnawing the protective layer, which still poses a danger. Therefore, there is an urgent need for a new type of wire that can prevent rats from gnawing. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a wire based on electronic information transmission, which can effectively prevent rodents from gnawing without reducing the mechanical properties of the wire.

[0005] The present invention solves the above technical problems by the following technical means:

[0006] A wire based on electronic information transmission, the wire comprising a wire core and a shielding layer wound around the outside of the wire core, the shielding layer being wrapped with a skeleton, the gaps in the skeleton being filled with an anti-gnaw layer, the skeleton being wrapped with an extrusion belt, the inner surface of the extrusion belt being provided with an extrusion boss, the tip of the extrusion boss facing the wire core and piercing into the inside of the anti-gnaw layer, the extrusion belt being wrapped with a protective sleeve.

[0007] Furthermore, the extrusion belt is provided with a plurality of release holes.

[0008] Furthermore, the raw materials of the anti-chewing layer include: polyester polyol, diphenylmethane diisocyanate, silicone oil, triethylenediamine, dibutyltin dilaurate, camphor oil, orchid root, horn tree root, expanded perlite, and lithium magnesium silicate.

[0009] Furthermore, the preparation method of the anti-gnawing layer is as follows:

[0010] (1) Dry the roots of the mountain orchid and the horn tree, grind them into fine powder, and set aside;

[0011] (2) crushing the expanded perlite into particles, selecting the expanded perlite with a particle size of 0.5-0.8 mm, heating it to 900-1000°C at a temperature of 10°C / min, keeping it warm for 10-15 minutes, taking it out, cooling it to room temperature, adding the prepared micro powder, stirring it and compacting it, then stirring it twice, and then compacting it twice to obtain compacted perlite, then mixing the compacted perlite with lithium magnesium silicate and water, heating it to 120-150°C again, keeping it warm for 20-25 minutes, then taking it out and immediately placing it in an environment of 0-10°C to cool it down, and taking it out after it is completely cooled to obtain rat repellent particles;

[0012] (3) Mix dibutyltin dilaurate, polyester polyol and water and stir evenly to obtain solution A; mix polyester polyol, diphenylmethane diisocyanate and dibutyltin dilaurate and stir evenly to obtain solution B; add silicone oil and mouse repellent particles to solution A and stir evenly, then mix with solution B; add camphor oil and stir rapidly; after the reactant becomes thick, transfer it to a mold, place it at room temperature for 30-50 minutes and then bake it at 60-70°C for 1-1.5 hours to obtain an anti-chewing layer.

[0013] The gnaw layer of the present invention is added with rat repellent particles, and the rat repellent particles use the roots of mountain orchid and horn tree to repel rats, and the rat repellent effect reaches 100%. Expanded perlite is selected as a carrier to load the rat repellent material and add it to the anti-gnaw layer, which can effectively prevent rats from further gnawing the wire and causing damage to the inside of the wire. When preparing the rat repellent particles, the pores of the perlite are first opened at a heating rate of 10°C / min, and micropowder is added and placed inside the expanded perlite through multiple vibration operations, and then mixed with lithium magnesium silicate and calcined for a second time. The lithium magnesium silicate plays the role of end-capping and wrapping. At the same time, the perlite is hardened under the condition of 120-150°C, so that the micropowder inside the perlite is difficult to precipitate without the action of external force, so that the rat repellent particles will take effect after being prepared into cables, thereby extending the service life of the rat repellent particles.

[0014] Furthermore, the mass ratio of dibutyltin dilaurate, polyester polyol and water in the A solution is 0.1:2:5, the mass ratio of polyester polyol, diphenylmethane diisocyanate and dibutyltin dilaurate in the B solution is 4:2:0.1, and the mass ratio of the A solution to the B solution is 1:(3-3.2).

[0015] Furthermore, the mass ratio of the silicone oil to solution A is 10:1, and the mass ratio of the total mass of solution A and solution B to the rat repellent particles is 1:0.2.

[0016] Furthermore, in the step (2), the mixture is stirred at a rate of 300-400 r / min for 5-6 hours, compacted at a vibration frequency of 100 times / min for 10 minutes, then stirred a second time at a stirring rate of 500-600 r / min for 20-30 minutes, and then compacted a second time at a vibration frequency of 120 times / min for 10 minutes to obtain compacted pearlite.

[0017] Furthermore, the mass ratio of the micro-powder mixed with the perlite and the roots of the mountain sedge and the horn tree is 1:0.5, and the mass ratio of the roots of the mountain sedge and the roots of the horn tree is 2:1.

[0018] Furthermore, the mass ratio of the lithium magnesium silicate to the tapped perlite is 1:1. Furthermore, the amount of camphor oil added is 0.01 of the total mass of the A solution and the B solution.

[0019] Furthermore, the shielding layer is an aluminum-plastic composite tape shielding layer, the protective sleeve is a low-density polyethylene sleeve, and the skeleton and the extruded tape are made of resin.

[0020] The wire core of the present invention can be a multi-strand twisted wire core or a single-strand wire core, and the skeleton provided in the wire of the present invention can not only play a supporting and buffering role, but also play a protective role when the wire is rotated or twisted. An anti-gnaw layer is provided in the middle of the skeleton, and the prepared rat-repellent particles are arranged inside the anti-gnaw layer. When the wire is transported, delivered or installed, the extrusion boss on the extrusion belt will be squeezed into the internal anti-gnaw layer due to contact or collision, so that the rat-repellent material in the rat-repellent particles is released through the release hole and filled into the pores inside the anti-gnaw layer, forming an all-round rat-repellent environment without dead ends inside the cable. When the mouse gnaws, the rat-repellent material inside the anti-gnaw layer is released through the release hole, which plays a role in repelling or killing the mouse. Moreover, since the anti-gnaw layer has a waterproof and moisture-proof foaming structure, the extrusion belt can also penetrate into it, further playing a buffering role, and further protecting the internal wire core of the cable.

[0021] Beneficial effects:

[0022] The cable of the present invention has a multiple buffer structure, which can ensure that the cable is evenly handled during transportation, avoid damage to the internal wire core, and further improve the impact resistance. In addition, the cable of the present invention has an anti-gnawing layer inside, which can effectively repel mice and prevent rodents from gnawing the cable and further damaging the internal structure of the cable.

[0051] The anti-gnawing layers prepared in Example 2 and Comparative Examples 1-3 were subjected to avoidance tests:

[0052] Experimental animals: House mouse;

[0054] Experimental method: House mice were domesticated for 7 days, with one mouse in each cage. A bait box was built in the cage. The anti-gnawing layer was cut into pieces and placed in the same bait box with the feed. The mice did not eat for 10 hours before the experiment.

[0055] Food selection test: Place a bait box containing only feed (left end) and a bait box containing a mixture of an anti-gnawing layer and feed (right end) at the two ends of the mouse cage, and observe the feed preservation rate after 48 hours.
