Description
Technical field
The utility model is related to coal mining apparatus field, in particular to a kind of coal mine flame-retardant fire-resisting cable.
Background technology
From the seventies, it is have generation because cable fire is in successive years, the fire-retardant problem of electric wire has caused various countries
Common concern, competitively develops flame-retardant electric wire and cable product.People mainly have great expectations of halogen containing polymers cable for a long time, several
The staple market of electric wire is monopolized.
Further study show that the electric wire that burns in a fire produces substantial amounts of dense smoke, make rescue work be difficult to into
OK, personnel are frequently not to be scorched to death, but by the smoked asphyxia of smog.Halogen-containing materials discharge HCL or other poisonous corrosivity
Gas, these poisonous corrosive gas and dense smoke not only jeopardize the life security of people, can also corrode the facilities such as instrument and meter.
The flame retardant products of mine cable industry are much not reaching to flame-retardancy requirements at present, and the generation that can so increase accident is several
Rate, affects the safety and reliability of Mining Market.
Utility model content
The purpose of this utility model is to provide a kind of coal mine flame-retardant fire-resisting cable, to solve the above problems.
For realizing the utility model purpose, the technical scheme of employing is：A kind of coal mine flame-retardant fire-resisting cable, including outer shield
Set, oxygen barrier layer, armor, neck bush and band；At least three groups conductors are provided with the band；Outside every group of conductor successively
Cladding is provided with screen layer, flame retardant coating, insulating barrier and insulation shielding；Packed layer is additionally provided with the band.
Further, the oversheath is halogen-free flameproof flexible sheath, and neck bush is alkali-free glass fibre layer.
Further, the packed layer is ceramic fibrous material.
Further, the band is high fire-retardance gluing glass belt.
Further, the flame retardant coating is fire retardant polyolefin flame retardant coating.
The beneficial effects of the utility model are that the utility model adopts multilayer multiple material, can prevent oxygen and combustion gas
The erosion of body, can form effective protective layer at high temperature, prevent the infringement to cable bag, with excellent fire resistance
And heat-proof quality, can effectively prevent spreading and propagating for the intensity of a fire, it is ensured that Mining Market safe and reliable.

Specific embodiment
Below by specific embodiment and combine accompanying drawing the utility model is described in further detail.
A kind of coal mine flame-retardant fire-resisting cable that the shown the utility model of Fig. 1 is provided, including oversheath, oxygen barrier layer,
Armor, neck bush and band；At least three groups conductors are provided with the band, and conductor is the stranded flexible conductor of copper wire；
Outside every group of conductor, cladding is provided with screen layer, flame retardant coating, insulating barrier and insulation screen successively, and screen layer is mainly used in leading
The shielding of body, screen layer are constituted using tinned copper wire braiding；Packed layer is additionally provided with the band, and packed layer is filled in band
Between insulation screen.
The oversheath is halogen-free flameproof flexible sheath, with excellent fire resistance and heat-proof quality, and processing cost
Low；Neck bush is alkali-free glass fibre layer, with the soft performance of fire-retardant, heat-insulated and anti-electricity.The packed layer is ceramic chemical fibre
Dimension material, with good resistance to fire action.The band is high fire-retardance gluing glass belt, has preferable anti-flammability.Described resistance to
Fire bed is fire retardant polyolefin flame retardant coating, with preferably resistance to fire action.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvement that is made etc., should be included within protection domain of the present utility model.
