Accompanying drawing explanation

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

Fig. 1 is structural representation of the present utility model；

In figure: conductor wire core 1, flame retardant coating insulating barrier 2, belting layer 3, armor 4, restrictive coating 5.

Detailed description of the invention

As it is shown in figure 1, one can porcelain nano-composite insulating materials of aluminum alloy fireproof cable, including a cable core and being coated on External protection outside cable core, cable core is made up of conductor wire core 1, flame retardant coating insulating barrier 2, and the employing rare earth of described conductor wire core 1 is high Ferroaluminium material, refractory insulating layer 2 uses can porcelainization nano combined fire-resistant silicon rubber insulant.Can porcelainization nano combined It has possessed the fundamental characteristics of usual silicone rubber good springiness to fire-resistant silicon rubber material at normal temperatures, has height nontoxic, tasteless, resistance to Ozone aging warm, resistance to, weatherable, excellent electrical insulation capability, also possessed the processing characteristics that common high temperature silicone rubber is good, Flexible cable state can be kept to about 200 degree above freezing at 40 degrees below zero.When flame invasion and attack temperature reaches more than 300 degree, can be by former The soft condition come is converted to rigid sponge ceramic body, and hardening rear fireproof jointing sheath is internal produces hole, is conducive to insulation, this Sample sponge ceramic body has significantly fire prevention and intercepts the effect of high temperature, thus the internal structure being effectively protected cable does not occurs Metataxis and electrical property change.

Cable external protection is followed successively by belting layer 3, armor 4, restrictive coating 5 from inside to outside, and belting layer (3) uses ceramic Fireproof silicone rubber composite band material wrapped forms through the most overlapping, and armor (4) uses high-strength aluminum alloy band self-locking Armouring mode, restrictive coating (5) uses halogen-free intumescent flame-retardant refractory material.

Belting layer 3 uses ceramic fireproof silicone rubber composite band wrapped to form through the most overlapping, and ceramic fire prevention is resistance to Fire silicone rubber composite band be to prolong pressure with ceramic fireproof silicone rubber and high temperature resistance glass fiber cloth for base material to be composited, 350 DEG C with The hardening housing forming ceramic-like is started at upper temperature.The housing that " ceramic " is hard in case of fire can play well Fire-retardant, fire-resistant, fire prevention, the effect of fire insulation, reach as high as 3000 DEG C, effective guarantee circuit unimpeded.

Armor 4 uses aluminum alloy strip self-locking armouring mode, is totally different from traditional steel-tape armouring structure, this armor Have resistance to compression, tension, shock resistance, flexible, corrosion-resistant, lightweight, installation is convenient, can exempt from pipeline or crane span structure is installed, insect protected Mus Sting, fire-retardant rank high.

Restrictive coating 5 uses expansion type flame-retarding technology, with nitrogen as host element, in the environment of fire, by acid source (dehydrant), carbon The sheath material of source (carbon forming agent) and source of the gas (foaming agent) three part composition expands rapidly, and surface forms the porous carbon bubble of densification Foam layer, is securely attached on cable, play good oxygen barrier, heat insulation, press down cigarette and can prevent drippage effect.Expand Type halogen-free flameproof refractory material has the function of good flame-retardant smoke inhibition and self-extinguishment, will not produce smog and have " secondary disaster " The strongest hydrogen halide of corrosivity, low cigarette, Halogen, fire-retardant and there is high elongation at break (＞ 350%), and processing Convenient.The fire-retardant fireproof effect of halogen-free intumescent flame-retardant protective layer is mainly the low of the heat insulation-foaming structure by foamed char Conduction of heat and to thermal-radiating reflection, trapping effect, limits underlying polymer oxygen supply and suppression combustibility degraded gas Release and effectively prevent the melted drippage behavior of polymer combustion generation to reach the effect of fire-retardant fireproof.

Owing to this utility model is provided with multi-layer fireproofing structure, it is achieved that multiple protection functions, it is ensured that combining of utility model Close fire protecting performance.

This utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model Other various forms of products, no matter but in its shape or structure, make any change, every have same as the present application or phase The technical scheme of approximation, within all falling within protection domain of the present utility model.
