Background technology
Current fire protection flame retarding cable mostly adopts magnesium oxide mineral insulation or mica tape to be wound around and realizes fire-resistant function.
But magnesia mineral hot-face insulation cable exists following shortcoming in Manufacture and application: the first, and equipment cost is high, magnesia mineral hot-face insulation cable needs special manufacturing and processing equipment, and expensive, equipment cost is higher; The second, production cost is high, and because the outer jacket of magnesia mineral hot-face insulation cable is full copper, the price of copper is high, makes production cost higher, in practical application, by restriction to a certain extent; 3rd, laying installation and the use of production and processing, transport, circuit are inconvenient, because copper sheath magnesia mineral fire-proof insulation cable has particular/special requirement in the laying installation and use procedure of production and processing, transport, circuit, production and processing as magnesia mineral fire-proof insulation cable can not easy making process image height molecular material, laying installation very complicated, cost of raw material cost is high, be difficult to extensive popularization and application, particularly civil buildings etc., could not obtain extensive, general application up to now.
And the fire-resisting cable that mica tape is wound around, in process of production, need multi-lay winding, due to the restriction of process conditions, overlap joint defect does not possess water resistance often to cause overlapping the slot place to occur, adds the easy embrittlement of mica tape after burning, comes off, reduce fire-resistant effect to a great extent, cause line short, thus be difficult to ensure electric power, communication in the case of fire safe and smooth.Mica tape sealing is also bad, and often fluorine-containing in material, does not meet the requirement of some halogen-free cables.
Currently marketed ceramic composite band product many employings one side ceramic glue and glass-fiber-fabric are composited, although have certain tack between ceramic glue, but the tack that ceramic glue face and glass cloth cover overlap mutually when wrapped is very faint, substantially not there is good sealing, do not have the effect of water-fast protection against the tide.
