Description
Technical field:
The utility model relates to a kind of environment-protective halogen-free low-smoke flame-retardant fire and heat endurance anticorrosive insulation electric wire, belongs to technical field of electric wires and cables.
Background technology:
Along with the raising of people's environmental consciousness, common PVC insulated electric conductor is because be eliminated gradually containing noxious substances such as halogens, a kind of novel environment friendly insulated electric conductor arises at the historic moment, current environment-friendly type insulated electric wire mainly adopts polyethylene insulation electric wire and crosslinked polyetylene insulated electric wire, but this cable does not have anti-flammability and thermal endurance, greatly have impact on the operating characteristic of cable.In addition in recent years, in public place fire, casualties is comparatively large, produces a large amount of smog and poisonous gas when main cause is the use of a large amount of inflammable combustible materials and burning.Because China is populous, public place density of personnel is comparatively large, and in fire, the personnel death of 80% is because sucked toxic combustion induced gas in public places, produces the evacuation that a large amount of smog is also unfavorable for personnel during burning.
In this case, the environmental protection insulated electric conductor of type of will looking for novelty not only will have excellent insulation electrical performance, mechanical performance, and will have certain flame-retarding characteristic, heat-resistant quality and fire-resistance property.
The environment-friendly type insulated electric wire manufacture of heat and flame of current China is also in the primary stage, add that technical merit and the level of processing of each cable producer domestic are uneven, and the requirement of environmental-protection flame-retardant hot-face insulation electric wire is comparatively strict, cause certain production difficulty to domestic manufacturer.Along with the development of China's flame-retarded technology, technical merit that is fire-retardant and fire-resisting cable is also progressively improving, but fire-resisting cable still rests on the main mica tape that adopts as fireprotection layer, in order to ensure the security against fire problem of the important events such as public place, answer good, the low cigarette of popularizing selection fire resistance, low toxicity, the fire-resisting cable of environmentally safe.This just requires that producer must break-through skill barrier, sets up the R&D team of oneself, develops the product with independent intellectual property rights, like this, will drive the development of enterprise, will produce good Social and economic benef@.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of environment-protective halogen-free low-smoke flame-retardant fire and heat endurance anticorrosive insulation electric wire, there is Halogen, low cigarette, fire-retardant, fire-resistant, heat-resisting, anticorrosion, the characteristic such as heat-proof aging and environmental protection, can extensive use civilian and variously there is place that is fire-retardant, fire-resistant and environmental requirement, excellent product performance.
The utility model technical solution problem adopts following technical scheme:
A kind of environment-protective halogen-free low-smoke flame-retardant fire and heat endurance anticorrosive insulation electric wire, by oxygen-free copper conductor, extrudes the Ceramic silicon rubber fireprotection layer on described conductor and extrudes and form in the outer field insulating barrier of described fireprotection layer.
Described insulating barrier is 150 DEG C of irradiation crosslinking halogen-free low-smoke flame-proof polyolefin insulating barriers.
Described insulating barrier is Ceramic silicon rubber insulating barrier, and the Thickness Ratio of described fireprotection layer and described insulating barrier is 4:6.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model fireprotection layer adopts a kind of new ceramics SiClx elastomeric material, " Ceramic silicon rubber " is a kind of novel polymer composite, doing fireprotection layer with it can be in the event of a fire, generate ceramic-like stiff shell, scene of fire indirectly mechanical shock can be resisted, ensure the unimpeded of electric power, communication line, work when flame ablation 90-180min not short circuit, open circuit; Ceramic silicon rubber fireprotection layer makes cable have high flame retardant and high fire resistance, its fire resistance is up to state standards category-A bunched burning test that GB/T19666-2005 specifies requires and its fire resistance is up to state standards fire resistance test requirement that GB/T19666-2005 specifies, ensure that the fail safe that cable uses in case of fire.
2, the utility model insulation employing 150 DEG C of irradiation crosslinking halogen-free low-smoke flame-proof polyolefin insulating material, insulate after electron irradiation is crosslinked, heat resistance and mechanical performance improve greatly, guarantee that cable has excellent heat-resisting and mechanical performance.Serviceability temperature reaches 150 DEG C simultaneously, and compared with common cable, ampacity significantly improves, and thermal endurance class is high, and useful life rises appreciably.
3, the utility model fireprotection layer Ceramic silicon rubber can also do insulating barrier, and namely this electric wire is equivalent to have employed double hyer insulation technology, and external insulation thickness proportion is 4:6, ensure that cable has excellent high electrical insulation properties.
4, all material of the utility model product all adopts LSOH anti-flaming material, ensure that cable loop guaranteed cost.When the utility model product has a burning, smoke density is very low, non-corrosiveness gas is overflowed, do not produce harmful hydracid material, possess the advantages such as low cigarette, Halogen, heat-resisting, high flame retardant, high fire-resistant and environmental-protecting performance simultaneously, the place that some personnel relatively concentrate can be widely used in yet.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 conductor, 2 fireprotection layers, 3 insulating barriers.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: the environment-protective halogen-free low-smoke flame-retardant fire and heat endurance anticorrosive insulation electric wire of the present embodiment, it is by oxygen-free copper conductor 1, extrudes the Ceramic silicon rubber fireprotection layer 2 on conductor 1 and extrude and form in the outer field insulating barrier 3 of fireprotection layer 2.
In specifically arranging, insulating barrier 3 can be made up of 150 DEG C of irradiation crosslinking halogen-free low-smoke flame-proof polyolefin insulating material; Insulating barrier 3 also can be made up of Ceramic silicon rubber material, and fireprotection layer 2 is 4:6 with the Thickness Ratio of insulating barrier 3 in such cases.Namely this electric wire is equivalent to have employed double hyer insulation technology, ensure that cable has excellent high electrical insulation properties.
