Description

A kind of environment-friendlyfireproof fireproof cable
(1) technical field
The present invention relates to field of cable technology, particularly a kind of environment-friendlyfireproof fireproof cable.
(2) background technology
At present, the occasion that the fire safety condition such as domestic skyscraper, oil, mine, subway, tunnel is high, the cable insulation used, restrictive coating mostly adopt the insulating material of Halogen.Fire, once spread, not only can produce a large amount of dense smoke, and can produce the very strong hydrogen halide of the corrosivity with " secondary disaster ", jeopardizes the life of people.Even adopt the flame-retardant insulating material of Halogen, low halogen; also can only delay flame-retardant insulating material and be burnt till the time of powder; if continue to be burnt; just gradually powder and come off; lose protective effect; electric wire is easy to breakdownly cause short circuit, thus is difficult to ensure communication, electric power in case of fire safe and smooth.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of rational in infrastructure, design science, fire prevention, nontoxic, environmental protection, fail safe are high, still energising can be maintained under being suitable for specific disaster scenario, for the emergency power supplies such as disaster relief power supply, illumination, communication low smoke and zero halogen, nontoxic environmental protection fireproof cable, solve problems of the prior art.
The present invention is achieved through the following technical solutions:
A kind of environment-friendlyfireproof fireproof cable, comprises several cable inner cores, at the outside wrapped lapping layer of cable inner core, fills a packed layer, is provided with a twisted shape fireprotection layer in lapping layer outside, be provided with a sheath in twisted shape fireprotection layer outside between lapping layer and cable inner core; Described cable inner core comprises conductor wire core, and described conductor wire core is stranded conductor or bundle glue conductor, at the wrapped flame retardant coating of conductor wire core outer gap, is provided with an insulating barrier in flame retardant coating outside.
Described lapping layer is fire-retardant gluing glass cloth tape; Described packed layer is flame retardant inorganic paper string; Described twisted shape fireprotection layer is work out containing the chlorinated rubber twisted shape of glass fibre; Described sheath is ceramic halogen-free flameproof fireproof; Described flame retardant coating is high-quality mica tape; Described insulating barrier is 105 DEG C, 125 DEG C or 150 DEG C of low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layers.
The invention has the beneficial effects as follows: this environment-friendlyfireproof fireproof cable insulating barrier is on the basis of traditional fireproof cable structure, by increasing and changing corresponding structure and material, design the high-quality mica tape flame retardant coating outwards set gradually by cable core, 105 DEG C, 125 DEG C or 150 DEG C of low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layers, flame retardant inorganic paper string packed layer, fire-retardant gluing glass cloth tape lapping layer, containing the chlorinated rubber twisted shape fireprotection layer of glass fibre, ceramic halogen-free flameproof fireproof, this structural design fire prevention safety performance is higher, product can at thermal-flame, under mechanical shock effect, the ability of normal work is still possessed within a very long time, can not spread, burning and generation pernicious gas, reach the designing requirement of environment-friendlyfireproof fireproof cable.This environment-friendlyfireproof fireproof cable is insulated by common flame-proof polyvinyl chloride and changes to low-smoke non-halogen flame-retardant cross-linking radiation polyolefine material, the high-energy electron line that this crosslinking method utilizes electron accelerator to produce, bombardment insulating barrier, macromolecular chain is interrupted, free radical is become by each breakpoint interrupted, free radical is unstable, will reconfigure each other, reconfigure rear original chain-like molecular structure and become three-dimensional netted molecular structure and formed crosslinked.Cable properties after irradiation: 1, ampacity increases 15%-30%; 2, long service life; 3, environmental protection, safety.The twisted shape fireprotection layer structural design arranged between lapping layer and sheath, resistance to elevated temperatures is more excellent.Restrictive coating is changed to ceramic halogen-free flameproof fireproof by common flame-proof polyvinyl chloride material, and this material is nonpoisonous and tasteless at normal temperatures, has good flexibility and elasticity, and good processability.Under high temperature more than 500 DEG C and flame ablation, organic principle ablatedly in a short period of time can change into hard ceramic-like material, form the isolation layer that one deck is good, stop burning away of flame, and the ablation time is longer, temperature is higher, and hard effect is more obvious, can reach the fire-resistant environment of 1200-1500 DEG C.Remained without any ashes by after burning simultaneously, really serve the object of fireproofing function and safety and environmental protection.The economic environmental protection of this environment-friendlyfireproof fireproof cable, can reduce the cost of cable, and the processing technology of this material is simple simultaneously, and batch production efficiency is higher, quality is more stable.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 cable inner core, 2 lapping layers, 3 packed layers, 4 twisted shape fireprotection layers, 5 sheaths, 6 conductor wire cores, 7 flame retardant coatings, 8 insulating barriers.
(5) embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the present invention will be described in detail.
As shown in Figure 1, this environment-friendlyfireproof fireproof cable comprises several cable inner cores 1, at the outside wrapped lapping layer 2 of cable inner core 1, fills a packed layer 3 between lapping layer 2 and cable inner core 1, be provided with a twisted shape fireprotection layer 4 in lapping layer 2 outside, be provided with a sheath 5 in twisted shape fireprotection layer 4 outside; Described cable inner core 1 comprises conductor wire core 6, and described conductor wire core 6 is stranded conductor or bundle glue conductor, at the wrapped flame retardant coating 7 of conductor wire core 6 outer gap, is provided with an insulating barrier 8 in flame retardant coating 7 outside.
