Abstract
The invention discloses an active fireproof cable capable of becoming ceramic when catching fire. The active fireproof cable capable of becoming the ceramic when catching the fire comprises a woven material winding layer, a combustion material layer, a silicone rubber composite material layer and a cable inner core. The active fireproof cable capable of becoming the ceramic when catching the fire has the advantages that the flexibility performance is needed by wires and cables before laying, the flexibility performance is not needed any longer after laying is accomplished, and after the cables are laid, the cables lose flexibility through combustion, and have the fireproof performance.
Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to a kind of active fireproof cable and preparation facilities thereof of meeting fire can ceramic.
Background technology
In the use procedure of electric wire, fireproof defect is the born defect of electric wire, conventionally in order to make electric wire can be smoothly through crooked paving location, electric wire has to adopt flexible macromolecular material, but as macromolecular material, a kind of petroleum derivation material, is difficult to change inflammable essence, although it is fire-retardant to adopt the methods such as fire retardant to carry out, be difficult to stop the flammable essence of macromolecular material.
As can be seen here, still there is defect in above-mentioned existing electric wire, and is urgently improved.
Summary of the invention
The shortcoming existing in using for existing electric wire, the invention provides a kind of active fireproof cable of meeting fire can ceramic.
The present invention is achieved in that a kind of active fireproof cable of meeting fire can ceramic, comprises braided material winding layer, incendiary material layer, silicon rubber composite material layer and cable inner core.
Better, the component of the material of above-mentioned silicon rubber composite material layer comprises methyl vinyl silicone rubber 22 ~ 35 weight portions, kaolin 12 ~ 25 weight portions, low-melting glass powder 17 ~ 25 weight portions, magnesium powder 5 ~ 12 weight portions, potassium permanganate or potassium nitrate 5 ~ 12 weight portions and auxiliary agent 2 ~ 10 weight portions.
Better, the material of above-mentioned knit layer is steel wire.
Better, above-mentioned knit layer has mesh structural porous structure.
Better, above-mentioned cable inner core comprises and realizes the wire of conduction current or the signal of telecommunication and the insulating material between wire.
Better, above-mentioned auxiliary agent is the one or any several of benzoyl peroxide, silane coupler, plasticizer.
Better, the material of above-mentioned incendiary material layer comprises string powder, potassium chlorate, manganese dioxide, sulphur, glass dust and glue.
Better, the component of the material of above-mentioned incendiary material layer comprises string powder 69 ~ 85 weight portions, potassium chlorate 3 ~ 5 weight portions, manganese dioxide 1 ~ 5 weight portion, sulphur 1 ~ 4 weight portion, glass dust 2 ~ 7 weight portions and glue 2 ~ 10 weight portions.
A kind ofly use active method of meeting the fireproof cable that fire can ceramic to be: at above-mentioned active chance after fireproof cable that fire can ceramic laid, one section of braided material winding layer of ring-type strip off, employing naked light pilot combustion material layer.
The principle that realizes of the present invention is, by one section of braided material winding layer of ring-type strip off, adopt naked light pilot combustion material layer, incendiary material layer can smoulder as Buddhist is fragrant, and then heating silicon rubber composite material layer, and the magnesium powder in silicon rubber composite material layer is oxidized, and provide oxygen by the potassium permanganate being heated or potassium nitrate, and then the temperature of silicon rubber composite material layer is improved suddenly, methyl vinyl silicone rubber decomposes, low-melting glass powder melts, and then make various products comprise kaolin and the compound ceramic material that becomes of vitreous material, after this ceramic forming materials, just lost soft curved performance, but externally in the barbecue of naked light, ceramic material just can completely cut off the calcination of naked light to cable inner core, that is to say, even the plastic material melted by heat of cable inner core, because completely cut off oxygen, and fettered well by ceramic material, just there will not be the common phenomenon of dripping glue burning, guarantee the mutually insulated of conductor.
Advantage of the present invention is: electric wire needs flex capability before laying, but it is just ineffective to have laid later flexility, and at this time, the mode by smoulder makes cable lose pliability, has but possessed fire protecting performance.
