Background technology
At present, people are to the needs of quick transmission data, information, and the dependence of computer, word processor, fax, transducer and communication equipment is increased significantly apace.The appearance of new technology make the equipment of this respect online with networking become possibility, caused the comprehensive development of communication system.These systems increase in the use of specific area, like skyscraper, and boats and ships, aircraft, train, drilling platforms and mine.In order to connect these electronic devices and components, need in these structures and field, use a large amount of electric wire and cables.Typically, in air handling system and electric wire pipeline, electric wire being installed is to use easily.Because air-conditioning and electric wire pipeline are continuous through these devices; The fail safe of insulation and sheath material is basic demand; Promptly require these materials to have low flame propagation and cigarette to form speed, and under various adverse environment conditions, carry out different physical properties.
The insulating barrier of present heatproof flame-retardant cable and restrictive coating generally are that single fire retardant and CABLE MATERIALS are mixed and made into.A large amount of fire retardants that use have not flame-retarding power as the plain based flame retardant of an ancient small-mouthed wine vessel, but generate a large amount of smog and poisonous gas during burning, and it is measured with ignition temperature and increases and increase, so can only be used for low-temperature flame retardant.Recently the halogen-free flame-retardant smog that uses is few, and toxicity is little or nontoxic, but contains a large amount of hydration materials, when temperature is high because dehydration has reduced physics, the mechanical performance of cable, so resistance combustion temperature can not be high.In a word, owing to use single fire proofing, cable is not that a large amount of smog of generation and toxic gas are exactly because of dehydration reduces cable performance, thereby influences the resistance combustion temperature and the duration of fire resistance of cable.As everyone knows, because rainwater is many, cable trough or cable tunnel ratio are easier to receive the rain drop erosion humidity at China's southern area; And products such as the inorganic putty of the fire-proof sealing material that is adopted in the traditional cable ditch or back-fire relief bag; After receiving rain drop erosion, moisture-sensitive distortion, firm poor performance; The back-fire relief effective performance is had a strong impact on, and is difficult to reach fire-retardant, fire prevention, moistureproof effect.
Some shortcoming of existing fluorine-containing cable insulation structure is overcome by the appearance of polyvinyl chloride/polytetrafluoroethylene/Kynoar insulated cable structure.At USP4, in 605,815; A kind of construction of cable is disclosed; By the conductor of at least a employing pvc coating insulation, the braiding glass crust and the Kynoar protective coat of dipping tetrafluoroethene are formed, though this construction of cable provides good non-conductive property; Fire-retardant smoke retaining, but also need further improve its fire-retardant smoke retaining.
Owing to formulated more strict fire safety standard; The wire cable insulating material require improves its burning and invention performance; Keep good physical property simultaneously; Low expense wire cable insulating material compositions is needed to improve its flame propagation and smoke generation characteristics, simultaneously good physical property will be arranged.
The utility model content
The technical problem that the utility model will solve is the deficiency that solves prior art, can not generate a large amount of smog and poisonous gas when a kind of the burning is provided, can not dewater, the flame retardant cable of fire-retardant, fire prevention, protection against the tide.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flame retardant cable, and it comprises cable core, lead, insulating barrier, packed layer, fireproof paint layer, protective sleeve; Said cable core is for being cut with scissors and formed by 3-20 root lead; Lead is the metal wire of diameter 1mm-20mm, and cable core quantity is the 1-4 root, and the cable core outside is an insulating barrier; Insulating barrier coats the fireproof paint layer outward; The fireproof paint layer of cable core is outward a band, and the band outside is a protective sleeve, and the gap between fireproof paint layer and band is a packed layer.
Said lead is diameter 3mm-12mm.
Said lead is diameter 8mm.
Said cable core quantity is 1, the rounded structure in the cross section of cable core.
Said cable core quantity is 2, cable core cross section semicircular in shape structure, and every cable core has oneself insulating barrier and fireproof paint layer, and externally by protective sleeve they is bundled together.
Said cable core quantity is 3, and the cross section of cable core is the sector structure of 120 ° of side angles, and the inside five equilibrium of all cable core angles is arranged, and every cable core has oneself insulating barrier and fireproof paint layer, and externally by protective sleeve they is bundled together.
Said cable core quantity is 4, and the cross section of cable core is the sector structure of 90 ° of side angles, and the inside five equilibrium of all cable core angles is arranged, and every cable core has oneself insulating barrier and fireproof paint layer, and externally by protective sleeve they is bundled together.
The physics of the utility model product cable, mechanical performance and heatproof flame-retardant performance are very good.200 ℃ of heat-stable times, elongation at break, the hot strength of heatproof flame-retardant material is impacted brittle temperature, specific insulation, performance index such as dielectric strength all are superior to international standard and national standard.Heat-resistant fireproof prescription is according to the IEC code test, in mechanical performance, and ageing properties, resistance to low temperature, insulation resistance, the darkness of smog, the damage by fume index, poison exponent, performance index such as the acid number of smog all reach or are superior to the IEC standard.
Performance index
The utlity model has following beneficial effect:
Test through to finished cable shows: finished cable checked to the bonding degree of different parts that the result was good after wearing out in 100 ℃ * 7 days.3500 volts of 5 minutes dielectric strength passed examinations ,-15 ℃ of low-temperature bendings and shock test are excellent.Carry out frame propagation test according to NFC32070 (or IEC332-1), show to have high flame retardant.Carrying out noninflammability can test, and noninflammability reaches 4 hours more than 840 ℃, 3-5 fray-out of flame second.Production of the present invention need not increase new in addition equipment and change production operation process and step, need only make suitable process modification.Realize easily producing in enormous quantities.Product cost is low.The cost of product of the present invention is 1/4th of an external similar performance product price.Product of the present invention can be used for comprising various building private cables, and power cable and telecommunication cable can be widely used in skyscraper, blast furnace, subway, mine, private cables such as computer, power distribution room, fire alarm, intracity communication, satellite communication.
