2. solution common polyvinyl chloride electric wire thermal stability is poor, anti-aging property is weak, the ageing-resistant performance of electric wire is improved And service life；

3. solve common polyvinyl chloride electric wire in a fire voluntarily prolong combustion, improve its fire-retardant and fire protecting performance, prevent electricity The fire incident that line cable triggers occurs；

4. solving common polyvinyl chloride electric wire shorted to earth can be caused to trigger circuit burning to cause fire when short circuit is overloaded；

5. it is low to solve common polyvinyl chloride electric wire current-carrying capacity, its current-carrying capacity is improved.

Brief description of the drawings

The structure diagram of Fig. 1 the utility model.

Embodiment

Below in conjunction with the accompanying drawings, the utility model is described in detail.

As shown in Figure 1, the utility model includes conductor 1, the outside of conductor sets gradually fire resistant calcining synthesis White clouds mother layer 2, high temperature resistance non halogen low-smoke and flame retardant ceramic polyolefin insulation layer 3 and the crosslinking of LSOH anti-flaming high-temperature resistant nano are poly- Dilute hydrocarbon insulating layer 4, conductor are copper conductor.

The utility model is these defects existing for common polyvinyl chloride electric wire, devises a kind of new double insulation knots The anti-aging environmental-protection fireproof electric wire of high temperature resistant of structure, employs high temperature resistance non halogen low-smoke and flame retardant ceramic polyolefin in its product structure Insulating materials and 125 DEG C of LSOH anti-flaming high-temperature resistant nano crosslinking polyolefin insulating materials are led as total insulator, and in height It with the addition of the calcining synthesis muscovite Novel fireproof rock-forming mineral material of fire resistant function admirable on the anaerobic copper conductor of electric rate Material, and 125 DEG C of LSOH anti-flaming high-temperature resistant nanos crosslinking polyolefin insulating materials are employed outside it.This new double insulation The anti-aging environmental-protection fireproof electric wire of high temperature resistant of structure, it is high temperature resistant degree degree, fire protecting performance, insulation performance, anti-overload ability, anti-ageing Change 125 DEG C of LSOH anti-flaming high-temperature resistant nanos crosslinking polyolefin insulation material that the superiority of performance is more prominent, and product uses Material, is that cross-linked polyolefin environmental protection sheath material is irradiated using the high energy electron line of electron accelerator, makes polyene Former relatively independent strand becomes the tridimensional network that same layer is connected, is connected layer by layer in hydrocarbon molecule structure, so that greatly Improve the physical mechanical property of external insulation layer, Heat-resistant stable performance, anti-aging property and raising product service life.

The utility model not only nonpoisonous and tasteless and non smoke, environmental-protecting performance in burning is excellent.Its temperature resistant grade can reach 1600 DEG C, heat resistanceheat resistant photooxidation aging property protrudes, and product service life can reach more than 70 years.And there is good Physical Mechanical Can be with good chemical-resistance and good technique processability.Under high temperature and flame ablation more than 1200 DEG C, resistance to height The calcining synthesis muscovite of warm LSOH anti-flaming ceramic crosslinked polyolefin insulating material and fire resistant function admirable is new anti- Fiery rock-forming mineral material composition ablated in a short period of time can change into a kind of hard duricrust of curing shape material generation, make One layer of good thermal insulation layer is formed on wire conductor surface, stops burning away for flame, and the ablation time is longer, and temperature is got over Height, it is more obvious to cure the stiffening effect of shape material, electric wire is placed on flame and remains to normally convey electric energy, when burning does not produce halogen Change hydrogen pernicious gas and smog, improve the visibility of scene of fire, effectively won the time for rescue fire, while be fire Victim in calamity creates the chance of escape.This fire resisting environment of the curing shape material at 1200 DEG C by after high-temp combustion Under, electric wire is still maintained normal operating status in burning situation.Remained after being burnt at the same time without any ashes.Really rise The purpose of good high temperature resistant, anti-aging, fireproof effect and safety and environmental protection is arrived.Simultaneously because the project is to devise one kind The anti-aging environmental-protection fireproof electric wire of high temperature resistant of new structure, the maximum operating temperature that allow wire conductor allows for a long time reach More than 100 DEG C, it can be seen that the safe carrying capacity of electric wire can increase substantially in the case of same cross-section.It is such as common poly- The safe carrying capacity when conductor of vinyl chloride insulated electric conductor 1.5mm2 allows 70 DEG C of maximum temperature for a long time is 24 (A), if selection Using the anti-aging environmental-protection fireproof electric wire of the high temperature resistant of the Project design, then current-carrying capacity can improve 1.4 times (project is through SLQ- The experiment of 500A strong current generators has proven to this point), avoided so as to reach since circuit design mistake brings electric wire to overload Operation causes aging circuit, the purpose for the fire that insulation resistance declines and triggers.

The utility model is forged high temperature resistance non halogen low-smoke and flame retardant ceramic polyolefin and fire resistant function admirable Burnt together is crosslinked polyolefin insulation material into muscovite Novel fireproof rock-forming mineral material and LSOH anti-flaming high-temperature resistant nano Material is combined in wire structure, the properties of electric wire is improved comprehensively, makes high temperature resistant, anti-aging and environmentally friendly and anti- The cost performance of thermoelectricity line finds full expression.This Project Product is suitable for Halogen, low cigarette, flame-retardancy requirements and safety and environmental protection and requires height Place.Such as skyscraper, station, subway, airport, hospital, large-scale library, gymnasium, villa, home dwelling, hotel, doctor The crowded places such as institute, office block, school, market, amusement park.

The utility model is not limited to above embodiment, can also there is many deformations.Those of ordinary skill in the art's energy All deformations for directly exporting or associating from the utility model disclosure, are considered as the protection model of the utility model Enclose.
