The present invention provides the one can porcelain nano-composite insulating materials of aluminum alloy fireproof cable, can porcelainization nano combined fire-resistant silicon rubber insulant it has possessed the fundamental characteristics of usual silicone rubber good springiness at normal temperatures, there is nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weatherable, excellent electrical insulation capability, also possessed the processing characteristics that common high temperature silicone rubber is good, flexible cable state can have been kept at 40 degrees below zero to about 200 degree above freezing.When flame invasion and attack temperature reaches more than 300 degree; rigid sponge ceramic body can be converted to by original soft condition; hardening rear fireproof jointing sheath is internal produces hole; be conducive to insulation; so sponge ceramic body has significantly fire prevention and intercepts the effect of high temperature, thus the internal structure being effectively protected cable does not occur metataxis and electrical property change.
Ceramic fireproof silicone rubber composite tape layers uses ceramic fireproof silicone rubber composite band wrapped to form through the most overlapping, ceramic fireproof silicone rubber composite band is to prolong pressure with ceramic fireproof silicone rubber and high temperature resistance glass fiber cloth for base material to be composited, and starts the hardening housing forming ceramic-like under 350 DEG C of temperatures above.The housing that " ceramic " is hard in case of fire can play the most fire-retardant, fire-resistant, fire prevention, the effect of fire insulation, reaches as high as 3000 DEG C, effective guarantee circuit unimpeded.
Armature of cable layer uses aluminum alloy strip self-locking armouring mode, being totally different from traditional steel-tape armouring structure, this armor has resistance to compression, tension, shock resistance, flexible, corrosion-resistant, lightweight, installation is convenient, can exempt from pipeline or crane span structure installation, insect protected damaged by rats, fire-retardant rank high.
Halogen-free intumescent flame-retardant refractory protection uses expansion type flame-retarding technology; with nitrogen as host element; in the environment of fire; the sheath material being made up of acid source (dehydrant), carbon source (carbon forming agent) and source of the gas (foaming agent) three part expands rapidly; surface forms the porous carbon froth bed of densification; be securely attached on cable, play good oxygen barrier, heat insulation, press down cigarette and can prevent drippage effect.Halogen-free intumescent flame-retardant refractory material has the function of good flame-retardant smoke inhibition and self-extinguishment, smog will not be produced and there is the hydrogen halide that the corrosivity of " secondary disaster " is the strongest, low cigarette, Halogen, fire-retardant and there is high elongation at break (＞ 350%) and easy to process.The fire-retardant fireproof effect of halogen-free intumescent flame-retardant protective layer is mainly the low heat conductivity of the heat insulation-foaming structure by foamed char and to thermal-radiating reflection, trapping effect, limits underlying polymer oxygen supply and the releasing of suppression combustibility degraded gas and effectively prevents the melted drippage behavior of polymer combustion generation to reach the effect of fire-retardant fireproof.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
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 shown in Figure 1; one can porcelain nano-composite insulating materials of aluminum alloy fireproof cable; including a cable core and the external protection being coated on outside cable core; cable core is made up of conductor wire core 1, flame retardant coating insulating barrier 2; the employing rare earth high-iron aluminum alloy materials of described conductor wire core 1, refractory insulating layer 2 uses can porcelainization nano combined fire-resistant silicon rubber insulant.Can porcelainization nano combined fire-resistant silicon rubber material it has possessed the fundamental characteristics of usual silicone rubber good springiness at normal temperatures, there is nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weatherable, excellent electrical insulation capability, also possessed the processing characteristics that common high temperature silicone rubber is good, flexible cable state can have been kept at 40 degrees below zero to about 200 degree above freezing.When flame invasion and attack temperature reaches more than 300 degree; rigid sponge ceramic body can be converted to by original soft condition; hardening rear fireproof jointing sheath is internal produces hole; be conducive to insulation; so sponge ceramic body has significantly fire prevention and intercepts the effect of high temperature, thus the internal structure being effectively protected cable does not occur metataxis and electrical property change.
Cable external protection is followed successively by belting layer 3, armor 4, restrictive coating 5 from inside to outside; belting layer (3) uses ceramic fireproof silicone rubber composite band material wrapped to form through the most overlapping; armor (4) uses high-strength aluminum alloy band self-locking armouring mode, and 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, ceramic fireproof silicone rubber composite band is to prolong pressure with ceramic fireproof silicone rubber and high temperature resistance glass fiber cloth for base material to be composited, and starts the hardening housing forming ceramic-like under 350 DEG C of temperatures above.The housing that " ceramic " is hard in case of fire can play the most fire-retardant, fire-resistant, fire prevention, the effect of fire insulation, reaches as high as 3000 DEG C, effective guarantee circuit unimpeded.
Armor 4 uses aluminum alloy strip self-locking armouring mode, being totally different from traditional steel-tape armouring structure, this armor has resistance to compression, tension, shock resistance, flexible, corrosion-resistant, lightweight, installation is convenient, can exempt from pipeline or crane span structure installation, insect protected damaged by rats, fire-retardant rank high.
Restrictive coating 5 uses expansion type flame-retarding technology, with nitrogen as host element, in the environment of fire, the sheath material being made up of acid source (dehydrant), carbon source (carbon forming agent) and source of the gas (foaming agent) three part expands rapidly, surface forms the porous carbon froth bed of densification, be securely attached on cable, play good oxygen barrier, heat insulation, press down cigarette and can prevent drippage effect.Halogen-free intumescent flame-retardant refractory material has the function of good flame-retardant smoke inhibition and self-extinguishment, smog will not be produced and there is the hydrogen halide that the corrosivity of " secondary disaster " is the strongest, low cigarette, Halogen, fire-retardant and there is high elongation at break (＞ 350%) and easy to process.The fire-retardant fireproof effect of halogen-free intumescent flame-retardant protective layer is mainly the low heat conductivity of the heat insulation-foaming structure by foamed char and to thermal-radiating reflection, trapping effect, limits underlying polymer oxygen supply and the releasing of suppression combustibility degraded gas and effectively prevents the melted drippage behavior of polymer combustion generation to reach the effect of fire-retardant fireproof.
Owing to the present invention is provided with multi-layer fireproofing structure, it is achieved that multiple protection functions, it is ensured that the comprehensive fire protecting performance of invention.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under the enlightenment of the present invention; though but in its shape or structure, make any change, every have same as the present application or akin technical scheme, within all falling within protection scope of the present invention.
