Description
Technical field
The utility model relates to a kind of fireproof cable, belongs to technical field of electric wires and cables, especially a kind of environment-friendly fireproof cable.
Background technology
Make a general survey of wires and cables industry, fire prevention, low cigarette, Halogen have become three keywords in industry.The laying of fireproof cable can reduce the probability that fire occurs.When occurring when fire, low smoke and zero halogen material can increase the probability of personnel escape in closed area, because halogen-free material is relative to there being halogen material, the harmfulness of the gas discharged during burning to health is less.
According to the regulation of GB/T19666-2005 " fire-retardant and fire-resisting cable general rule ", the production technology of usual fire-resisting cable is all in the mode of the outer wrapped mica tape of conductor, plays fire-resistant effect.At present, the mica tape that cable industry uses is all Prof. Du Yucang, and containing fluorine element in mica tape, as breaking out of fire, the fluorine-containing toxic gas that burning produces reduces the escape probability of personnel; For improving fireproofing of cable grade, fire retardant can be added in the insulating material and jacket material of cable, but cable thus insulating material itself still can burn, once breaking out of fire, cable still can light raging flames.
Chinese patent (application number: CN201420529012.9, application publication number: CN204463899U) propose a kind of technique combined at the outer coated ceramic masking liquid of the outer braided glass fibre silk of conductor and substitute the technique extruding plastics outside traditional mica tape, thus reach fire-resistant object.This technique, complex process, and production efficiency is not high, will inevitably affect production efficiency in batch production.
Summary of the invention
For overcoming the defect of above-mentioned prior art, the utility model provides a kind of environment-friendly fireproof cable.
The technological means that the utility model adopts is: a kind of environment-friendly fireproof cable, comprises insulated wire cores and cable core, and described insulated wire cores comprises conductor, flame retardant coating, Halogen insulating barrier from the inside to the outside successively; Described flame retardant coating is the graphite synthetic mica tape that Graphene is made; Described cable core comprises outward successively: screen, fireprotection layer, armour and oversheath; Described fireprotection layer is made up of the rubber combined band of double-layer ceramic SiClx and single-layer ceramic fiber cloth.
Further, described conductor is band plated conductor.
Further, described conductor is real core conductor or stranded conductor.
Further, described insulated wire cores becomes cable core separately.
Further, at least two described insulated wire cores are twisted into cable core.
Further, the gap outside described insulated wire cores, in cable core is packed layer.
Good effect of the present utility model is:
1, a kind of novel graphite synthetic mica tape of Graphene manufacture is used to substitute traditional mica tape manufactured with artificial mica synthesis powder.This graphite synthetic mica tape has excellent mechanical property, resistance to elevated temperatures.
2, described graphite synthetic mica tape is not containing fluorine element, ensure that the gas that its burning produces does not contain poisonous halogen gas, to human body machine environment without adverse effect, and fundamentally stop problem fluorine-containing in ordinary mica tape relative to prior art, thus environment-friendly fireproof cable can have been applied to.
3, fireprotection layer is made up of the rubber combined band of double-layer ceramic SiClx and single-layer ceramic fiber cloth, this cable is had and keeps off fire, heat-blocking action efficiently, also can withstand shocks and shake simultaneously, and the infiltration of anti-sealing, and ceramic fiber cloth is with the use of the effect making cable reach efficient high-temperature resistant gear fire.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of the utility model insulated wire cores;
In figure: conductor 1; Flame retardant coating 2; Halogen insulating barrier 3; Packed layer 4; Screen 5; Fireprotection layer 6; Armour 7; Oversheath 8.
Embodiment
As shown in Figure 1, a kind of novel environment friendly fireproof cable, comprises insulated wire cores and cable core, and described insulated wire cores comprises conductor 1, flame retardant coating 2, Halogen insulating barrier 3 from the inside to the outside successively; Described flame retardant coating 2 is the graphite synthetic mica tapes be made up of Graphene; Described conductor 1 is band plated conductor; Described conductor 1 is real core conductor or stranded conductor; Described Graphene synthetic mica tape, replace traditional mica tape made with artificial mica synthesis powder, this Novel cloud master tape has excellent mechanical property, resistance to elevated temperatures, and described graphite synthetic mica tape is not containing fluorine element, ensure that the gas that its burning produces does not contain poisonous halogen gas, to human body machine environment without adverse effect, fundamentally stop problem fluorine-containing in ordinary mica tape; Described Halogen insulating barrier 3 is not halogen-containing insulating material, as crosslinked polyethylene, and IXPE, the insulating material such as ethylene-propylene rubber.
Described cable core comprises outward successively: screen 5, fireprotection layer 6, armour 7 and oversheath 8; Described fireprotection layer 6 is wrapped on described screen 5, the material of described fireprotection layer 6 is the rubber combined band of double-layer ceramic SiClx coated single-layer ceramic fiber cloth formation again, described ceramic fiber cloth puts up rate 45% ~ 50%, the rubber combined band of described double-layer ceramic SiClx is when flame combustion, namely start to sinter hard ceramic-like armouring housing into after burning 2-4min, the isolation layer of this hard ceramic-like armouring can the burning away of very effective stop flame; And being given up smoking completely by burning about 2min, in ensuing ablation journey, itself no longer including smog and producing; The smog that produces in the 2min in early stage is also Halogen, nontoxic, harmless; Smog is the rear solid flue dust produced of organosilicon burning mainly, the material of the ceramic-like after burning is hard, uniform cellular housing, such object has excellent thermal insulation, fire insulation fire resistance, effective maintenance circuit unimpeded, also can withstand shocks and shake simultaneously, and the infiltration of anti-sealing, and ceramic fiber cloth is with the use of the effect making cable reach efficient high-temperature resistant gear fire; At the outer wrapped armour 7 of described fireprotection layer 6, to strengthen the mechanical strength of cable, outermost layer is silicon rubber oversheath 8, has excellent resistance to elevated temperatures; Gap outside described insulated wire cores, in cable core is packed layer 4, and described packed layer 4 is halogen-free flameproof high temperature glass fiber rope, can ensure the fire resistance of cable.
