Abstract
The invention relates to a cable. A fluoroplastic lightweight flame-retardant cable comprises an outer insulating layer, an inner insulating layer and a cable core, wherein a flame-retardant layer is arranged between the outer insulating layer and the inner insulating layer; a flame-retardant filler is arranged between the inner insulating layer and the cable core; compressed flame-retardant gas is filled in the flame-retardant layer; the outer insulating layer contains a fluoroplastic component; and the inner insulating layer contains the fluoroplastic component. According to the technical scheme, the fluoroplastic lightweight flame-retardant cable has the advantages of light weight, high flame-retardant capacity and the like.
Description
Technical field
The present invention relates to cable, be specifically related to a kind of flame retardant cable.
Background technology
Cable is the main mode of dispensing electrical transmission, and along with development and national economy, the cable demand increases year by year.At the bottom of ground, the ocean, be provided with cable everywhere in the air, it brings huge help for our life and work electricity consumption.
Because it much is flammable that the manufactured materials of cable has, cable also becomes one of root of breaking out of fire.Therefore, have the flame retardant cable of numerous model structures on the market, but the flame retardant cable of conventional art nearly all is to adopt the structural design of common cable to add what fire proofing formed, in fire-retardant, certainly will also increase the cable own wt.
Though these cables have increased the material of flame-retardant in cable; But after the long-time burning of these flame-retardant materials, breaking also can appear in cable jacket, and has smog during burning; Even can discharge toxic and harmful, also can't stop the burning of flame to the cable internal layer.
Summary of the invention
The objective of the invention is to, a kind of fluoroplastics light flame-retardant cable is provided, solve above technical problem.
The technical problem that the present invention solved can adopt following technical scheme to realize:
Fluoroplastics light flame-retardant cable; Comprise external insulation layer, inner insulating layer, cable core, it is characterized in that, be provided with flame-retardant layer between said external insulation layer and the inner insulating layer; Be provided with fire-retardant filler between said inner insulating layer and the cable core, be filled with the anti-flammability gas of compression in the said flame-retardant layer;
Said external insulation layer contains the fluoroplastics composition, and said inner insulating layer contains the fluoroplastics composition.
The anti-flammability gas of compression is not only stable, in light weight, and can effectively stop flame invasion inner insulating layer.
Advantages such as said external insulation layer and said inner insulating layer all adopt the flame-proof silicon rubber material, and it is fire-retardant, water-fast, wear-resisting that flame-proof silicon rubber has.That fluoroplastics have is high temperature resistant, do not prolong characteristics such as combustion.Add the fluoroplastics composition and can effectively improve the performance that cable is resisted adverse circumstances.
Said fire-retardant filler is the flame-retardant low-smoke halogen-free filler, can realize fire-retardant purpose, because not halogen-containing toxigenicity does not again contain heavy metal, and environmental protection, harmless to health.
In case fluoroplastics light flame-retardant cable breaking out of fire; The flame external insulation layer that burns for a long time; In case after breaking appearred in external insulation layer, flame got into flame-retardant layer, the anti-flammability gas of the compression of flame-retardant layer is as the fire retardant knock down the flame; The present invention is handicapping combustion filler in inner insulating layer also, reaches the dual fire-retardant effect of preventing, protecting cable core.
Beneficial effect: owing to adopted technique scheme, the present invention to have advantages such as own wt is light, fire retardancy is strong.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, further set forth the present invention below in conjunction with concrete diagram.
With reference to Fig. 1; Fluoroplastics light flame-retardant cable comprises external insulation layer 1, inner insulating layer 3, cable core 5, is provided with flame-retardant layer 2 between external insulation layer 1 and the inner insulating layer 3; Be provided with fire-retardant filler 4 between inner insulating layer 2 and the cable core 5, be filled with the anti-flammability gas of compression in the flame-retardant layer 2.The anti-flammability gas of compression can be the anti-flammability gas of compressions such as nitrogen, carbon dioxide.The anti-flammability gas of filling compression is not only stable, in light weight, and can effectively stop flame invasion inner insulating layer.External insulation layer 1 contains the fluoroplastics composition, and inner insulating layer 2 contains the fluoroplastics composition.That fluoroplastics have is high temperature resistant, do not prolong characteristics such as combustion.Add the fluoroplastics composition and can effectively improve the performance that cable is resisted adverse circumstances.
Advantages such as external insulation layer 1 all adopts the flame-proof silicon rubber material with inner insulating layer 3, and it is fire-retardant, water-fast, wear-resisting that flame-proof silicon rubber has.Fire-retardant filler 4 is the flame-retardant low-smoke halogen-free filler, can realize fire-retardant purpose, because not halogen-containing toxigenicity does not again contain heavy metal, and environmental protection, harmless to health.
In case fluoroplastics light flame-retardant cable breaking out of fire; The flame external insulation layer that burns for a long time; In case after breaking appearred in external insulation layer, flame got into flame-retardant layer, the anti-flammability gas of the compression of flame-retardant layer is as the fire retardant knock down the flame; The present invention is handicapping combustion filler in inner insulating layer also, reaches the dual fire-retardant effect of preventing, protecting cable core.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
