Anti-explosion cable and preparation method thereof

Abstract

The invention discloses an anti-explosion cable and a preparation method thereof. The anti-explosion cable sequentially comprises a cable conductor core, an insulating layer, a shielding layer, a phase change material layer, a waterproof layer, a first anti-explosion layer, a compression-resistant layer, a second anti-explosion layer, a flame-retardant layer and a jacket layer. An extrusion process is adopted to coat the insulating layer outside the cable conductor core, the shielding layer is formed by overlapped lapping, the phase change material layer is adhered outside the shielding layer, and the waterproof layer is coated on the phase change material layer; the extrusion process is adopted to coat the first anti-explosion layer on the waterproof layer, and the compression-resistant layer and the second anti-explosion layer are sequentially coated on the first anti-explosion layer; a double-extrusion process is adopted to coat the flame-retardant layer and the jacket layer on the second explosion layer to form the anti-explosion cable. The anti-explosion cable is reasonable in structure, good in flame-retardant performance, anti-explosion performance, anti-interference performance and mechanical performance, low in cost, safe to operate and quite convenient to use, performances of the cable are improved, anti-explosion safety of the cable is improved, and the anti-explosion cable is more convenient and more reliable to use.

Description

technical field [0001] The invention relates to a cable, in particular to an explosion-proof cable and a preparation method thereof. Background technique [0002] With the development of society, cables are used more and more widely, and there are more stringent and diverse requirements for the performance of cables. Continuously improving the performance of sheath materials is an urgent need for economic and social development. Explosion-proof cables have been widely used in some places with explosive hazards. For example, in warehouses, chemical companies, gas stations, gas stations, oil companies and other places with high safety requirements, explosion-proof cables are required to meet these places. High demands on security. In order to prevent damage to the cable caused by the storm shock wave caused by the explosion, as well as electromagnetic interference between the line and the surrounding equipment, a circular explosion-proof plate, steel wire armor, and copper wi...

AI Technical Summary

Problems solved by technology

Existing explosion-proof cables are realized by installing a circular explosion-proof plate inside the cable, mainly steel wire armor and copper wire armor, so that the cable will not be damaged under the action of external force, but this structure reduces the flexibility of the cable. , bending; the addition of the explosion-proof plate will increase the weight of the cable itself, which increases the difficulty of installation and laying on the one hand, and on the other hand makes the cable only suitable for use on land, not on ships

[0003] In addition, with the rapid development of the economy, there are various special requirements for cables, but the current cable waterproof, anti-static field, explosion-proof performance, and pressure resistance performance are poor, especially the cables cannot have any problems during use. The cable structure can no longer meet the diverse requirements
