A kind of fire-proof and pressure-resistant rubber special-shaped cable and its preparation process

Abstract

The invention discloses a fire-proof and pressure-resistant rubber special-shaped cable and a preparation process thereof. It has good fire-proof and flame-retardant performance and extrusion resistance, and the molding quality is high during the preparation process. The key points of the technical scheme include an outer sheath and a A number of wires in the outer sheath, the wires include a wire core and an insulating layer coated on the outer wall of the wire core, a flexible skeleton with a flat structure is provided inside the outer sheath, the wires are arranged horizontally and equidistantly and embedded in a flexible In the framework, a flame-retardant sheath is provided between the outer sheath and the flexible framework, and a flame-retardant filling layer is also provided between the flame-retardant sheath and the outer sheath. The invention is applicable to the technical field of cables.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a fireproof and pressure-resistant rubber special-shaped cable and a preparation process thereof. Background technique [0002] Cables are generally used to transmit electrical energy, electrical signals, etc., and cables have become an indispensable part of information transmission in today's life. At present, when the cable is used, there are many harsh environments, and the cable is prone to damage in the harsh environment, so the cable in the harsh environment needs to be maintained frequently, and the cost is extremely high, especially in the high temperature environment, the cable Excellent insulation, fire resistance, and high temperature resistance are the most basic conditions for cables, and fire is also a common disaster at present, and in the process of disasters, power protection settings rely on cables to transmit signals and electric energy to a large extent. Let i...

At present, when the cable is used, there are many harsh environments, and the cable is prone to damage in the harsh environment, so the cable in the harsh environment needs to be maintained frequently, and the cost is extremely high, especially in the high temperature environment, the cable Excellent insulation, fire resistance, and high temperature resistance are the most basic conditions for cables, and fire is also a common disaster at present, and in the process of disasters, power protection settings rely on cables to transmit signals and electric energy to a large extent. Let it work, therefore, the fire performance of the cable is very important for today's production and life

[0003] Existing flame-retardant cables have relatively simple flame-retardant methods, and the flame-retardant methods are usually directly using flame-retardant rubber sleeves, or applying flame-retardant coatings, or spraying flame-retardant powder on the surface of the rubber layer. The method of forming a flame-retardant layer, but the existing coating method and spraying method do not have suitable proprietary equipment. Traditional spraying, dipping and spraying guns and other equipment or methods have defects, which will affect the molding quality. Therefore, it needs to be improved; in addition, the existing flame-retardant cables must contain multiple wires, and the adjacent wires are mainly separated by fillers such as wire ropes, but the stability is poor, the extrusion resistance is insufficient, and there is no Has good thermal conductivity
