Description
Technical field
The present invention relates to a kind of fire resisting data bus cables of flame retardant coating containing mica, are suitable for field of track traffic safety
The requirements fire prevention higher occasion of condition such as door, subway, inter-city passenger rail, magnetic suspension, EMU, high-speed rail and recovery number.
Background technique
China in Recent Years rail traffic industry is researched and developed again by international cooperation and digestion and absorption, realizes the big hair of great-leap-forward
Exhibition obtains consistent approval both domestic and external；The promotion of the independent research and development capacity of the rapid development and China of China's rail traffic is close not
It can divide, to putting forward higher requirements for the data bus cable of the data transmission as rail traffic vehicles, relatively narrow
The requirement of fire resisting data bus cable is proposed at the major trunk roads in small space.
In the past to the requirement of data cable just for transmission performance and the environmental resistance of use occasion, there has been no fire safe types
Data bus cable；
Fire resisting data bus cable need to be wanted by GB/T 19216 (IEC 60331-23) 90min+15min fire resistance test
It asks, the mica tape used is generally phlogopite or synthetic mica tape.With the presence of the force majeure factor such as various earthquakes, cable
In combustion in case of mechanical oscillation, cable will lose fire-resistance property, and mechanical oscillation are occurred in fire incident
Probability is high.Still toxic gas release when conventional mica tape fire-resisting cable burning simultaneously, for low smoke and zero halogen non-toxic product
Propose special requirement.Therefore, under above-mentioned background condition, a kind of novel resistant environmental low-smoke halogen-free flame type fire safe type is needed
Data bus cable guarantees that cable can continue reliably working when fire occurs to meet the requirement of rail traffic development trend.
Summary of the invention
Aiming at the problem that above-mentioned outer diameter and weight, the invention proposes a kind of fire resisting data/address bus electricity of flame retardant coating containing mica
Cable, purpose aim to solve the problem that the data cable of maintenance route integrality of the rail traffic data/address bus under Fire Conditions
Problem.
In order to solve problem above, present invention employs following technical solutions: a kind of fire resisting data of the flame retardant coating containing mica
Bus cable, including cable inner core, filled core, wrapping layer, plastic-aluminum combined belt, drain wire, woven shield, oversheath；Often
Root cable inner core includes conductor, flame retardant coating, insulating layer, is flame retardant coating outside conductor, is insulating layer outside flame retardant coating；Filled core and cable
It is wrapping layer outside inner core, is plastic-aluminum combined belt outside wrapping layer, is woven shield, aluminium-plastic tape and volume outside aluminium-plastic tape
Knitting is drain wire between shielded layer, is oversheath outside woven shield；It is characterized by:
The flame retardant coating is the calcining mica tape in conductor layer outer layer longitudinal wrap；The calcining mica tape is by calcining muscovite paper
Closing single layer alkali-free glass fiber cloth supporting material composition with high temperature resistant organic silicone adhesive has good fire retardant property, low cigarette, nothing
Halogen, nontoxic, good flexibility, heatproof is up to 950 DEG C or more.
The wrapping layer is the wrapped calcining mica tape of left-hand, wrapped calcining mica tape after stranding；The calcining mica tape
Being closed single layer alkali-free glass fiber cloth supporting material with high temperature resistant organic silicone adhesive by calcining muscovite paper and formed has good fire resisting resistance
Performance, low cigarette, Halogen, nontoxic, good flexibility are fired, heatproof is up to 950 DEG C or more.
The calcining mica tape overlap rate of the flame retardant coating longitudinal wrap is preferably 10%~20%.
The wrapped calcining mica tape overlap rate of the wrapping layer is preferably 20%~30%.
The circular in cross-section of the every cable inner core, cable inner core are in that plane tangent is placed between each other；Such phase
The structure for cutting placement can guarantee final cable entirety circular in cross-section, and cable internal structure is even closer, securely.
The conductor is three, i.e., two big one is small, and filled core is one；Or the conductor is two, filled core
It is two；Or the conductor is four, filled core is one.
The conductor is to be twisted tin plating soft round copper stranded conductor, silver-plated soft round copper stranded conductor, the soft round copper stranded conductor of nickel plating, bare copper stranded wire.
The insulating layer is skin foam skin low dielectric loss polyethylene insulation.
The filled core is the low dielectric loss polyethylene being crosslinked by electron accelerator irradiation.
The shielded layer is double-sided aluminum plastic composite band, using longitudinal wrap structure.The composite shielding interlayer be it is tin plating (it is silver-plated,
Nickel plating or naked copper) round copper wire drain wire.The shielded layer is tin plating (silver-plated, nickel plating or naked copper) round copper wire braiding layer.
The restrictive coating is that irradiation crosslinking type oil resistant LSOH anti-flaming irradiates polyolefin jacket material through electron accelerator spoke
According to being cross-linked to form.
The fire resisting data bus cable conductor of the flame retardant coating containing mica uses multiply tin-coated copper soft (silver-plated soft round copper stranded conductor, plating
The soft round copper stranded conductor of nickel, bare copper stranded wire) conductor, longitudinal wrap calcines mica tape, the low medium of the outer extruding microporous of calcining mica tape outside conductor
Loss insulation and low smoke and zero halogen material make sheath, the wrapped calcining mica layer after more insulated wire cores are twisted, mainly in fire
Burning generates very low smog and micro poisonous gas and maintains route complete under environment, thus for field rescue personnel and interior
Portion's disaster affected people creates a good living environment and rescue condition.Simultaneously again since the cable is used with high energy electron
Ray irradiates organic thermoplastic material and it is made to be transformed into 3 D stereo cross-linked network by linear polymeric, i.e., with
Thermoplasticity is converted into insoluble insoluble thermosetting state, so that the operating temperature of wire and cable has reached 90 DEG C by original 70 DEG C, it is short
The overload-resistant temperature in road has reached 250 DEG C by original 160 DEG C, while also having improved physical mechanical property, and drop significantly
The low finished product outer diameter of wire and cable.
The present invention has the advantage that the present invention has fire-retardant rank high and fire resisting compared with the immediate prior art
Ability is strong, in the case where being subjected to the direct sustained combustion of flame, does not occur short circuit or open circuit, the transmission to guarantee data security, really
Protecting protection staff has time enough safe escape, and is conducive to loss of putting out a fire and reduce.
