Description

Fireproof electric wire

Technical Field

The utility model relates to a wire and cable technical field specifically indicates a fire prevention electric wire.

Background

Along with the rapid increase of urban population, facilities such as high-rise buildings, hotels, large supermarkets, hospitals and subways are rapidly increased, the importance of fire safety is highlighted, the national security production supervision and administration clearly requires that communication facilities are kept smooth when a fire disaster occurs, so that higher requirements are provided for the fire resistance of electric wires for supplying power to the communication facilities, the global temperature is warmer, the fire resistance requirements of the electric wires are higher and higher, the existing electric wires have not only fire resistance but also excellent heat insulation performance, and the fire resistance and the heat insulation performance of the existing electric wires are required to be improved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to solve above-mentioned problem, provide an improve electric wire fire prevention heat-proof quality's fire prevention electric wire.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a fire prevention electric wire, includes the electric wire body, the electric wire body is by outer fire-retardant layer, microcapsule galactose alcohol layer, polyaryl ester layer, insulating layer, armor, the layer of putting out a fire, inner sheath and the conductor of being equipped with in proper order to interior, the conductor outside is equipped with insulating rubber, be equipped with the anti-interference layer between insulating rubber and the inner sheath.

Compared with the prior art, the utility model the advantage lie in: the flame retardance of the wire is greatly improved by adopting a three-layer protection mode of a polyaryl ester layer, a microcapsule galactitol layer and a magnesium hydroxide flame retardant layer; the microcapsule galactitol layer can generate phase change and absorb heat, so that the temperature of the wire is reduced; the microcapsule galactitol and the magnesium hydroxide flame-retardant layer act together to release water after the combination chemistry, improve the concentration of environmental carbon dioxide and the like to perform flame retardance; the polyarylate layer has good high temperature resistance and can prevent or slow down the combustion.

As the improvement, the honeycomb structure is established to the fire extinguishing layer, the layer of putting out a fire establishes as an organic whole with the inner sheath, the honeycomb structure intussuseption on the layer of putting out a fire is filled with the soil of putting out a fire for it is fire-retardant.

As an improvement, the anti-interference layer is an asbestos layer, and asbestos has the effects of high tensile strength, high flexibility, chemical and thermal erosion resistance and electrical insulation, and improves the flame retardance and the external insulation performance of the conductor.

As an improvement, a vermiculite film layer is arranged outside the magnesium hydroxide flame-retardant layer, so that the heat-proof effect is good.
