Abstract
The invention discloses a flame retardant and fire resistant cable used for a coal mine, which comprises a central layer, an inner sheath layer and an outer sheath layer, wherein at least three groups of conductor are arranged in the central layer, the surfaces of each group of conductors are successively provided with fire resistant ceramic fiber layers and rock wool layers, the inner sheath layer surrounds the periphery of the central layer in arrangement, the outer sheath layer surrounds the periphery of the inner sheath layer in arrangement, a first fire retardant coating layer is arranged between the central layer and the inner sheath layer, and a second fire retardant coating layer and a fire retardant material blocking layer are successively arranged on the periphery of the outer sheath layer. By means of the abovementioned manner, the flame retardant and fire resistant cable used for the coal mine makes use of multilayer and multiple fire resistant materials, can prevent the corrosion of oxygen and combustion gas, can form an effective protection layer at high temperature, prevents damages to a cable matrix, has excellent flame retardant performance and heat-shielding performance, and can effectively prevent the spread of fire behavior.
Description
Technical field
The present invention relates to mining cable technical field, particularly relate 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.
