Description
Technical field
The utility model relates to mining cable technical field, particularly relates to a kind of coal mine flame-retardant fire-resisting cable.
Background technology
From the seventies, be 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, have almost monopolized the staple market of electric wire.
Further research finds that the electric wire that burns in a fire produces a large amount of dense smoke, and make rescue work be difficult to carry out, personnel are not often scorched to death, but is smoked by smog and suffocate.Halogen-containing materials discharges HCL or other poisonous corrosive gas, and these poisonous corrosive gass and dense smoke not only jeopardize the life security of people, also can the facility such as corrosion tester instruments and meters.
The flame retardant products of current mining cable industry does not much reach flame-retardancy requirements, can increase the occurrence probability of accident like this, affects the safety and reliability of Mining Market.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of coal mine flame-retardant fire-resisting cable; adopt the multiple refractory material of multilayer; the erosion of oxygen and burning gases can be stoped; at high temperature can form effective protective layer; prevent the infringement to cable matrix; there is excellent fire resistance and heat-proof quality, effectively can stop spreading and propagating of the intensity of a fire, ensure the safe and reliable of Mining Market.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of coal mine flame-retardant fire-resisting cable, comprise: central core, inner restrictive coating and external sheath layer, at least three group conductors are provided with in described central core, the described surface often organizing conductor is disposed with refractory ceramic fibre layer and rock wool layer, inner restrictive coating is put in the peripheral ring winding of described central core, external sheath layer is put in the peripheral ring winding of described inner restrictive coating, the first fireproof paint layer is provided with between described central core and inner restrictive coating, the periphery of described external sheath layer is also disposed with the second fireproof paint layer and fire prevention calking layer.
In the utility model preferred embodiment, described inner restrictive coating is alkali-free glass fibre layer.
In the utility model preferred embodiment, described external sheath layer is halogen-free flameproof flexible sheath layer.
In the utility model preferred embodiment, described first fireproof paint layer and the second fireproof paint layer include emulsion water-based material and fire-proof flame-retarded agent.
