[0001] The utility model belongs to the technical field of wires and cables, and in particular relates to a highly fire-proof and fire-resistant ceramic polyolefin mineral wire and cable. Background Art
[0002] The main fire resistance of wires and cables currently used on the market is mostly achieved through internal fillers or surface fire retardant coatings. However, since most wires and cables are directly exposed to the outside, the outer walls of wires and cables are prone to corrosion and damage during actual use, which makes it easy for the fire retardant coating and internal fillers to have protection loopholes. Therefore, a highly fire-resistant and fire-resistant ceramic polyolefin mineral wire and cable is designed to solve the problem that the fire resistance of the currently used wires and cables is not ideal. Utility Model Content
[0003] The utility model aims to provide a highly fireproof and fire-resistant ceramic polyolefin mineral wire and cable to solve the problem in the above background technology that the fireproof effect of the currently used wire and cable itself is not ideal.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a highly fire-proof and fire-resistant ceramic polyolefin mineral wire and cable comprises an inner layer, a barrier sleeve, a conductor and a protective layer, the inner layer is wrapped with a barrier sleeve, the barrier sleeve is wrapped with a conductor, and fire-proof fillers are filled between the barrier sleeves, and the protective layer is wrapped outside the inner layer.
[0005] Preferably, the protective layer includes a wrapping layer, a barrier strip and a ceramic polyolefin, the wrapping layer is wrapped around the outside of the inner layer, and a plurality of barrier strips are symmetrically arranged at equal intervals on the inner wall of the wrapping layer, the barrier strips are parallel to the inner layer, and the end faces of the barrier strips are in contact with the inner layer, and the inner layer and the wrapping layer are filled with ceramic polyolefin.
[0006] Preferably, convex strips are symmetrically arranged at equal intervals on the outer wall of the inner layer, the convex strips are embedded between the barrier strips, and the outer walls of the convex strips are in contact with the inner wall of the wrapping layer and the side walls of the barrier strips respectively.
[0007] Preferably, an outer layer is provided around the wrapping layer, the outer layer is bonded to the wrapping layer by glue, and a fire-retardant coating is applied on the outer wall surface of the outer layer.
[0008] Preferably, a second braided layer is provided between the outer layer and the wrapping layer and inside the glue, and the second braided layer is provided to cover the periphery of the wrapping layer.
[0009] Preferably, a first braided layer is arranged inside the inner layer, the first braided layer is in contact with the inner wall of the inner layer, and the conductive wire and the fireproof filler are both wrapped and arranged inside the first braided layer.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] (1) The utility model is provided with a wrapping layer, a barrier strip and a ceramic polyolefin. In actual use, the ceramic polyolefin is separated one by one by the barrier strip and the convex strip. When the wrapping layer is damaged, the barrier strip and the convex strip are used to block the ceramic polyolefin in other positions, thereby preventing the problem of large-scale leakage of the ceramic polyolefin. The setting of the wrapping layer also prevents the direct contact between the inner layer and the outside world. The fireproof performance of the cable is further improved by cooperating with the fireproof filler, thereby solving the problem that the fireproof effect of the currently used wires and cables is not ideal.
[0012] (2) The utility model is provided with an outer layer, a second braided layer and a fire-retardant coating. In actual use, the outer layer and the fire-retardant coating are used to isolate the wrapping layer from contact with the outside world.

The second braided layer is provided so that after the outer layer is damaged, foreign matter from the outside will not come into direct contact with the wrapping layer. Even if the wrapping layer is corroded after being soaked in rain for a long time, it can still be woven into a barrier to prevent ceramic polyolefin from flowing out, thereby increasing the service life of the cable.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-Figure 3 As shown, the utility model provides the following technical solutions: a highly fire-proof and fire-resistant ceramic polyolefin mineral wire and cable comprises an inner layer 4, a barrier sleeve 3, a conductor 5 and a protective layer, the inner layer 4 is wrapped with a barrier sleeve 3, the barrier sleeve 3 is wrapped with a conductor 5, and a fire-proof filler 8 is filled between the barrier sleeves 3 and the barrier sleeves 3, the protective layer is wrapped and arranged outside the inner layer 4, the protective layer comprises a wrapping layer 1, a barrier strip 7 and a ceramic polyolefin 10, the wrapping layer 1 is wrapped outside the inner layer 4, and a plurality of barrier strips 7 are symmetrically arranged at equal intervals on the inner wall of the wrapping layer 1, the barrier strips 7 are parallel to the inner layer 4, and the end faces of the barrier strips 7 are in contact with the inner layer 4, the inner layer 4 and the wrapping layer 1 are filled with ceramic polyolefin 10, and convex strips 11 are symmetrically arranged on the outer wall of the inner layer 4 at equal intervals, the convex strips 11 are embedded between the barrier strips 7, and the outer walls of the convex strips 11 are in contact with the inner wall of the wrapping layer 1 and the side walls of the barrier strip 7 respectively.
[0019] Through the above technical scheme: in actual use, the inner layer 4 is covered by the wrapping layer 1 to prevent the inner layer 4 from direct contact with the outside world, thereby reducing the possibility of damage and breakage of the inner layer 4. At the same time, the installed barrier strips 7 and convex strips 11 are used to separate the ceramic polyolefin 10 as a whole one by one, so that the ceramic polyolefin 10 as a whole is divided into multiple independent parts. Even if the wrapping layer 1 is damaged, the barrier strips 7 and convex strips 11 are used to block the flow of ceramic polyolefin 10 at other positions, thereby preventing the problem of large-scale leakage of ceramic polyolefin 10. In addition, the setting of the ceramic polyolefin 10 can also cooperate with the wrapping layer 1, the fireproof filler 8 and the inner layer 4 to further improve the overall fireproof performance of the cable, thereby solving the problem that the fireproof effect of the currently used wires and cables themselves is not ideal.
[0020] See also Figure 1 and Figure 3 As shown, an outer layer 6 is arranged on the outer periphery of the wrapping layer 1, the outer layer 6 and the wrapping layer 1 are bonded together by glue, and a fire-retardant coating 12 is applied on the outer wall surface of the outer layer 6, a second braided layer 9 is arranged between the outer layer 6 and the wrapping layer 1 and inside the glue, the second braided layer 9 covers the outer periphery of the wrapping layer 1, a first braided layer 2 is arranged inside the inner layer 4, the first braided layer 2 and the inner wall of the inner layer 4 are in contact with each other, and the conductor 5 and the fire-retardant filler 8 are both wrapped inside the first braided layer 2.
[0021] Through the above technical scheme: in actual use, the outer layer 6 and the fire-retardant coating 12 are used to isolate the wrapping layer 1 from the outside world to reduce the problem of damage to the wrapping layer 1. At the same time, the fire-retardant coating 12 applied is used to further increase the overall fire resistance of the cable. The second braided layer 9 is set so that after the outer layer 6 is damaged, foreign matter from the outside will not directly contact the wrapping layer 1. Even if the wrapping layer 1 is corroded by rainwater for a long time, it can be woven to prevent the ceramic polyolefin 10 from flowing out. After long-term use, when the outer wrapping layer 1 ages and falls off and the inner layer 4 is directly exposed to the outside, the fire-retardant filler 8 can be used to ensure that the cable has a certain fire resistance. Even if the inner layer 4 is damaged, the built-in first braided layer 2 can also block the leakage of the fire-retardant filler 8, thereby ensuring that the fire resistance of the cable is not affected to the greatest extent.
[0022] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
