Description

Technical Field

[0001] This utility model relates to the field of cable material science and technology, and in particular to a fireproof and flame-retardant wire and cable. Background Technology

[0002] With increasing societal awareness of safety, the demand for fire-retardant wires and cables is gradually rising. Governments worldwide have enacted a series of laws and regulations requiring the use of fire-retardant wires and cables in public facilities and critical infrastructure to ensure fire safety. The development of new flame-retardant materials, such as low-smoke halogen-free materials, has improved the flame-retardant performance of cables while reducing environmental pollution. Advanced production processes, such as heat shrinking, have improved cable production efficiency and product performance. With the acceleration of urbanization and the advancement of infrastructure construction, the market demand for fire-retardant wires and cables continues to grow. Numerous companies producing fire-retardant wires and cables have emerged in the market, leading to increasingly fierce competition and prompting companies to continuously improve product quality and service levels.

[0003] Most existing fire-retardant wires and cables have the problem that the materials used in the products may not fully meet the requirements of high flame retardancy, low smoke and halogen-free, resulting in insufficient flame retardancy in actual fire conditions. Furthermore, the protection provided to the wires and cables is not high enough, and the internal wires and cables may be damaged under external forces. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing fire-retardant wires and cables often use materials that may not fully meet the requirements of high flame retardancy, low smoke, and halogen-free properties, resulting in insufficient flame retardancy in actual fire situations and inadequate protection for the wires and cables, which may cause damage to the internal wires and cables under external forces. Therefore, this utility model proposes a fire-retardant wire and cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fireproof and flame-retardant wire and cable, comprising a flame-retardant polyolefin protective layer, an armor layer fixedly connected to the inner wall of the flame-retardant polyolefin protective layer, a ceramicized fireproof layer fixedly connected to the inner wall of the armor layer, a barrier layer fixedly connected to the inner wall of the ceramicized fireproof layer, and an oxygen barrier layer fixedly connected to the inner wall of the barrier layer.

[0006] Preferably, a silicone pad layer is fixedly connected to the inner wall of the oxygen barrier layer.

[0007] Preferably, a first fixing tube is fixedly connected to the inner wall of the silicone pad layer.

[0008] Preferably, a second fixing tube is fixedly connected to the inner wall of the silicone pad layer.

[0009] Preferably, a third fixing tube is fixedly connected to the inner wall of the silicone pad layer.

[0010] Preferably, the silicone pad layer has strong plasticity and strong ductility.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a flame-retardant polyolefin protective layer, a ceramicized protective layer, and an armor layer are used to enable the device to achieve high flame retardancy, low smoke, and halogen-free properties. Secondly, a ceramicized fireproof and refractory filling rope is used instead of the traditional glass fiber filling. This material can form a dense alumina covering layer when burning, which isolates oxygen.

[0013] 2. In this utility model, a silicone soft pad structure is used as a device for fixing wires and cables. It can fix wires and cables of different thicknesses very well. Secondly, the soft silicone material can protect the wires and cables well. In addition, multiple wire holes are opened so that wires and cables of various sizes and types can be installed separately, which is convenient for later identification. Attached Figure Description

[0019] In this embodiment, the flame-retardant polyolefin protective layer 1 is made of polyolefin material, which can play a role in high flame retardancy, smokeless and low halogen. The armor layer 2 is made of copper strip, aluminum strip or stainless steel strip to form a seamless tube. This armor structure can effectively protect the inner protective structure during combustion. The ceramicized fireproof layer 3 uses ceramicized fireproof and fire-resistant filling rope instead of traditional glass fiber filling. This material can form a dense alumina covering layer during combustion, which isolates oxygen. The barrier layer 4 prevents flame and heat from spreading outward through the conduction and radiation of the cable. The oxygen barrier layer 5 prevents oxygen from entering the combustion area, thereby improving the flame retardant effect.
