Abstract
The utility model patent relates to the electric wire that a kind of LSOH anti-flaming blocks water.Traditional PVC (polyvinyl chloride) electric wire, when fire occurs, PVC mixture easy decomposition after being heated is overflowed severe toxicity in a large number, the HCL that is corrosive (hydrogen chloride) gas, and produce a large amount of hypertoxic dense smoke, cause great Loss of Life and property, and bring very large difficulty to rescue work.The utility model is characterized in that arranging at least one layer of watertight composition outside described conductor wire core, and described watertight composition outer setting flame retardant insulation, described flame retardant insulation is made up of the crosslinked halogen-free material of high temperature resistant irradiation.The utility model fire protection flame retarding is good, and fail safe is high, and the life-span is permanent.
Description
Technical field
The utility model patent relates to a kind of civilian cable and wire, rated voltage 450/750V and following, it is characterized in that a kind of low smoke, zero halogen, fire-retardant, the cable and wire that blocks water.
Background technology
Traditional PVC (polyvinyl chloride) electric wire, when fire occurs, PVC mixture easy decomposition after being heated is overflowed severe toxicity in a large number, the HCL that is corrosive (hydrogen chloride) gas, and produce a large amount of hypertoxic dense smoke, cause great Loss of Life and property, and bring very large difficulty to rescue work.In order to the secondary injury avoiding and reduce fire and fire to cause as far as possible, find through large quantifier elimination for many years, change product cladding material used and technique, can effectively deal with problems.
The toxicity that the cable of Halogen discharges in fire is very fearful, if the toxicity of gas concentration of causing death can be judged to be 1 at 30min, so the poison exponent of polyvinyl chloride is 15.01, and the poison exponent of halogen free polymer is 0.79.During fire, the dense smoke strongly filled the air makes victim debate unclear direction, thus extends the time of being detained in fire.According to interrelated data introduction, when light transmittance is 70%, the naked ability depending on differentiating image of people only has about 5m.And the light transmittance of the cigarette sent during polyvinyl chloride burning is below 15%, namely people is in the cigarette of this dense smoke, and its naked apparent distance is only about 2m.Another feature of dense smoke is rapid with thermal current propagation anomaly, and speed can reach more than 20m/min.In addition, in repairs profession, be long-term wet area between bathroom, electric wire makes moist and is corroded, and the service life of electric wire reduces, and easily causes short circuit.
Utility model content
The object of the utility model patent to provide a kind of LSOH anti-flaming to block water electric wire, and fire protection flame retarding is good, and fail safe is high, and the life-span is permanent.
The technical solution of the utility model is: a kind of LSOH anti-flaming blocks water electric wire, comprise conductor wire core, it is characterized in that arranging at least one layer of watertight composition outside described conductor wire core, described watertight composition outer setting flame retardant insulation, described flame retardant insulation is made up of the crosslinked halogen-free material of high temperature resistant irradiation.
The beneficial effects of the utility model are: by LSOH anti-flaming block water technology innovation and be proposed novel high-performance environment-friendly type electric wire, effectively can solve PVC and fit up electric wire shortcoming, low smoke, zero halogen, fire-retardant, block water possesses excellent short circuit load ability simultaneously.Cover irradiation crosslinking halogen-free polyethylene flame-retardant insulating material outside the utility model, then by physical crosslinking, the flue gas Halogen after burning is non-toxic, to human body fanout free region.Simultaneously also there is good insulating properties, well isolated flame can be played, the effect of fire-proof insulation, thus ensure that in case of fire, electric power, communication unimpeded.The utility model utilizes the high energy electron line of electron accelerator to carry out irradiation to wire cable insulating layer and protective layer; the tridimensional network making the former relatively independent chain structure of plastic body become same layer to be connected, to be connected layer by layer; thus drastically increase the mechanical and physical performance of electric wire product, thermal endurance and useful life.
The utility model is applicable to rated voltage 450/750V and following, has low smoke, zero halogen, fire-retardant, block water requirement and the high place of safety and environmental protection requirement.As crowded places such as skyscraper, station, subway, airport, hospital, large-scale library, gymnasium, villa, home dwelling, hotel, hospital, office block, school, markets.
The utility model, when burning, only has light water smoke, visual range more than 60 meters; Not containing any noxious substance; The effect that electric wire reaches fire-retardant is made by irradiation crosslinking processes; The immersion of moisture content effectively can be prevented by watertight composition and water-swellable tape; Life-span is long: anti-aging, life-span can reach more than 30 years; High temperature resistant: maximum operating temperature can reach 125 degree;
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Embodiment
