Technical field
The utility model is related to the protective device of cable and cable, more particularly to a kind of line with automatic fire-extinguishing function
Cable protection pipe.
Background technology
Cable protecting tube also known as cable tube, electric power cable pipe, cement cable tube, electricity channel, electric power cable protection pipe etc..
Cable protecting tube is mostly installed at the location that communication cable intersects with power line, prevents power line from broken string occurs and causes short-circuit thing
Therefore cause communication cable and steel wire rope charged, to protect cable, interchanger, machine core board, so that complete machine is not burned, to electric power
Line magnetic interference also functions to certain buffer action.PE Cable protecting tubes are using high-quality high-density polyethylene resin to be main former
Material adds in a kind of new high-tech product of the extruded mode machine-shaping of suitable adjuvants.The product have it is corrosion-resistant, anti-aging,
Shock resistance, high mechanical strength, the performance characteristics such as service life is long, electrical insulation properties are excellent, can be widely applied to embedded high pressure
The fields such as cable, street lamp cable protection casing.It is widely used in urban road construction, quarter development, garden landscape, Enterprise Construction
Places are waited, as cables such as electric power, street lamp, Lawn lamp, garden lamp, Intelligent Home, cable television, communication, intelligent transportation
Wiring sheath pipe.
The integral structure that PE Cable protecting tubes now are usually used, effectively increases waterproof ability, but now
Cable be usually used made of PVC or CPVC materials, the heat resistance of PVC or CPVC materials is fairly limited, once
Short circuit occurs for cable, it is easy to cause fire.If Cable protecting tube is enabled to possess automatic fire-extinguishing function, then with regard to that can have
Effect improves cable security, preferably controls fire behavior.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model proposes a kind of Cable protecting tubes with automatic fire-extinguishing function.
In order to realize above-mentioned technical problem, the solution that the utility model is taken is：One kind has automatic fire-extinguishing function
Cable protecting tube, including PE tube bodies, a flame-retardant polyurethane thermal insulation layer is bonded on the medial surface of the PE tube bodies,
And then uniformly coated with a flame retardant type hot melt adhesive layer on the medial surface of the flame-retardant polyurethane thermal insulation layer, in the flame retardant type
Polylith fire resistance fibre cloth is uniformly bonded on the medial surface of hot melt adhesive layer.
It is further improved to be：The thickness of the flame-retardant polyurethane thermal insulation layer is 2.3-5.5mm.
It is further improved to be：The thickness of the flame retardant type hot melt adhesive layer is 0.8-1.5mm.
It is further improved to be：The polylith fire resistance fibre cloth is not of uniform size, and shape differs, and polylith fire resistance fibre cloth
The medial surface of complete covering flame retardant type hot melt adhesive layer.
It is further improved to be：The thickness of the fire resistance fibre cloth is 1.5-3.0mm.
By using preceding solution, the beneficial effects of the utility model are：The utility model uses the pipe of PE materials
Body has corrosion-resistant, anti-aging, shock resistance, high mechanical strength, the performance characteristics such as service life is long, electrical insulation properties are excellent,
And a variety of fire proofings are applied, in practical applications, once fire occurs in tube body, flame retardant type hot melt adhesive layer i.e. can be by
Heat, once reaching certain temperature, flame retardant type hot melt adhesive layer can melt, and reduce the bonding force between fire resistance fibre cloth,
So that fire resistance fibre cloth Automatic-falling, covering burning things which may cause a fire disaster, realize automatic fire-extinguishing function, simultaneously as fire-retardant fibre by obstructing air
Wei Bu uses decentralized design, may also function as the effect of pointing fire-extinguishing, i.e. where is on fire, and the fire resistance fibre cloth at this can take off automatically
Fall, put out a fire, in addition flame-retardant polyurethane thermal insulation layer can effectively reduce outer influence of the temperature environment to flame retardant type hot melt adhesive layer of pipe.
