Self-adaptive rigid-flexible dual-state fireproof cable

Abstract

The invention discloses a self-adaptive rigid-flexible dual-state fireproof cable, which belongs to the field of cables. The self-adaptive rigid-flexible dual-state fireproof cable is characterized in that in a high-temperature fire environment, external high temperature is firstly transferred to the interior of thermosetting filling liquid through heat-conducting air-filtering soft wires, so that water in the thermosetting filling liquid is heated to evaporate, water molecules are transferred to the outside through the heat-conducting air-filtering soft wires, and the thermosetting filling liquid is sintered into solid under high temperature after water loss. In the process, on one hand, the external temperature is consumed, evaporation of water in the thermosetting filling liquid is promoted, and meanwhile, steam evaporated to the outside plays a certain role in retarding a fire environment outside the cable core, and on the other hand, after the thermosetting filling liquid loses water and is sintered into the solid, a high-strength fireproof heat-resistant protective barrier is formed on the cable core to effectively protect the cable core, and meanwhile, the original flexible state of the cable at the position is changed into a rigid state, so that the fireproof protection of the cable is automatically realized, and the damage condition of the cable in a fire disaster can be conveniently and quickly judged and detected in the later period.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to an adaptive rigid-flexible double-state fireproof cable. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. As one of the most important cable product R&D and production bases in the world, China currently has Flame retardant, high temperature and low temperature resistance, low inductance and low noise, green environmental protection, low smoke and halogen-free, anti-ant and rodent, waterproof and moisture-proof, etc. A series of cable products with unique performance and special structure, and have formed a certain productive forces. With the continuous improvement of social security and system safety requirements, through the extensive publicity, promotion and cooperation of the government, industry and enterprises...

Problems solved by technology

These two cables have been used in the market for many years, but with the development of the times and the advancement of science and technology, the cables in the existing technology can no longer meet the needs of the development of the modernization process, such as multi-core cables in skyscrapers, tunnels, airports and other places. The demand for long-length cables is increasing day by day. These places require cables to have a long fire resistance time, and the production with the original old technology can no longer meet the modern needs.

[0004] However, due to the hard texture of the steel fireproof cable, it is very inconvenient for the construction, and the bending degree of the flexible cable is also small. Because the inner insulation is made of magnesium oxide, it is easy to cause cracks in the inner insulation when bending. Therefore, in the prior art This kind of cable can no longer meet the needs of the development of the modernization process
