A plurality of copper conductors are respectively enlaced and covered by two layers of fireproof mica tapes; the mica tapes are covered by the insulation layer; the copper conductor, the insulation layer and the mica tapes form a wire core; each wire core is covered by a low smoke halogen-free flame retardant oxygen barrier; the oxygen barrier is covered by the low smoke halogen-free polyolefine insulated jacket; the clearance among the wire cores is filled with low smoke halogen-free flame retardance organic mineral paper twine. The fireproof wire designed with the technical proposal of the utility model has high temperature resistance. When the wire is in high temperature environment or is burning, no halogen or poison is generated; life safety of people is ensured; precision equipment can not be eroded and atmospheric environment can not be polluted. The utility model can be extensively applied to fire fighting field.
Description
Technical field
The utility model has related to a kind of electric wire, is specially the irradiation crosslinking type low-smoke halogen-free flame-retardant fire-resistant wires.Belong to the electric wire field.
Background technology
Many occasions need can withstand high temperatures the electric wire product, succeeded in developing many on the market such as silicon rubber (allowing ambient operating temperature to be :-80 ℃-180 ℃) insulated cable, fluoroplastics (allowing ambient operating temperature to be :-120 ℃-260 ℃) insulated cable etc., but after having solved high temperature resistant this difficult problem, followed by some inevitable defectives having occurred, in these materials, contain a large amount of poisonous elements, as halogen etc.The temperature resistant grade of common polythene material is 70 ℃, after chemistry that process is general or physical process change crosslinked polyethylene into, can bear 90 ℃ long-term work condition, but can not calamity bear too high long-term permission working temperature.In case breaking out of fire accident, toxic gas with the serious harm life security, are corroded precision equipment, pollutant atmosphere.According to the requirement of fire-fighting and rescue, need the back electric wire take place in certain temperature at fire, still can continued power under the regular hour condition.
The utility model content
Goal of the invention of the present utility model is for a kind of irradiation crosslinking type low-smoke halogen-free flame-retardant fire-resistant wires is provided, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
This irradiation crosslinking type low-smoke halogen-free flame-retardant fire-resistant wires comprises copper conductor, insulating barrier and sheath, is surrounded with fire-resistant isinglass belt outside some copper conductors respectively, and insulating barrier is coated on outside the mica tape, and copper conductor, insulating barrier and mica tape are formed insulated wire cores; Each core is coated with the oxygen barrier layer of low-smoke non-halogen flame-retardant, and the low-smoke halogen-free polyolefin insulating sleeve is coated on outside the oxygen barrier layer; The space that forms between the core is that low-smoke non-halogen flame-retardant humatite paper string is filled.
Described mica tape is for being adhesive bonding phlogopite band paper or synthetic mica paper with the organosilicon, and two-sided or single face is a supporting material with alkali-free glass fibre or organic film respectively, through gluing, compound, cure, cut the banded fire-resistant isinglass belt that forms.Have good flexibility and mechanical strength when normality, good manufacturability is arranged when electric wire is wrapped, under 1000 ℃ the condition of high temperature, but still holding circuit is unimpeded more than the 90min continuously, has electrical insulation capability under the excellent high temperature.Fire-resistant isinglass belt avirulence gas during burning produces, characteristics such as heat insulation, the acid and alkali-resistance that also has simultaneously, anti-corona and radiation hardness.
Described oxygen barrier layer is a halogen-free low-smoke flame retardant material, dominant mechanism is to have added the metal hydrate composition in this material, meet high temperature and promptly can resolve into metal oxide and separate out the crystallization water, metal oxide decomposes the back and forms network structure, and flue gas is had certain suction-operated.And the crystallization water of separating out not only plays tangible settlement action to soot, but also has endothermic effect preferably.Can form carbonized structure in this external combustion process, this carbonized structure is being brought into play huge effect aspect the low cigarette of cable, fire-retardantization, burning rate when the heat-absorbing action delay cable takes fire itself and the time of sharply rising, because the formation of carbonized structure, thereby hindered the supply of oxygen and flowing of fuel gas, thereby hindered the burning of cable.
Irradiation low-smoke halogen-free polyolefin insulating material is adopted in insulation, and temperature resistant grade reaches 135 ℃.
The fire-resistant wires that designs by technical solutions of the utility model, not only have resistant to elevated temperatures characteristics, and electric wire Halogen when high temperature or burning is nontoxic, has guaranteed people's life security, can not cause burn into also can not pollute atmospheric environment to precision equipment.Can be widely used in fire-fighting domain.
