4th, material cost reduction.
Brief description of the drawings
Fig. 1 is a kind of structural representation of low-smoke bittern-free highly fire-proof communication cable of the invention；
Wherein, 1, conductor, 2, insulating barrier, 3, restrictive coating, 4, belting layer, 5, braiding layer.
Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of low-smoke bittern-free highly fire-proof communication cable, including some conductors 1, it is arranged on each conductor
HDPE insulating barriers 2 outside 1, coat the restrictive coating 3 of all conductors 1, are arranged on the belting layer 4 outside the restrictive coating 3
With the braiding layer 5 being arranged on outside the belting layer 4.The belting layer 4 includes the first mica belt and the second mica belt.Institute
State the first mica belt and mica tape is longitudinally coated on the outside of the restrictive coating 3；The second mica belt voluble wrapping is in institute
State the first mica belt outside.The braiding layer 5 is made up of glass fiber yarn.
A kind of manufacture method of low-smoke bittern-free highly fire-proof communication cable, comprises the following steps,
1）By HDPE insulating barrier coating conductors.
2）The conductor that two are provided with HDPE insulating barriers is arranged to one wire.
3）If carried interest wire is coated by high flame resistance, low smoke Halogen restrictive coating.
4）The belting layer being made up of the first mica belt and the second mica belt, first cloud are set outside restrictive coating
Mica tape is longitudinally coated on master tape layer the restrictive coating outside, and the second mica belt voluble wrapping is in first mica
Belt outside；The step 4）In, the rate of putting up of the belting layer is 48-50%.
5）Set outside belting layer and braiding layer is made by glass fiber yarn；The step 5）In, need choosing in braiding
Select the laying tension of suitable plug die and Go-over mould and braided wires so that the count of the braiding layer reach 95% with
On.
The cable increases flame-retardant low-smoke halogen-free protective cover material and composite mica tape using HDPE insulation and glass fiber yarn is compiled
The form knitted, mica tape is using vertical bag plus wrapped double form.Because composite mica band and glass fiber yarn have excellent
Resistance to elevated temperatures and flame resistance energy, HDPE insulating wrappeds inside band, cause the inside HDPE insulation can only melt,
And can not burn, so there is no concern that its flame spreads, in the absence of the volatilization of harmful vapors, so the product is used for cable not
But it is effectively, and very safe.The dense smoke for occurring to be emerged during fire will turn into the factor that obstruction personnel take refuge with fire-fighting rescue activity,
The smog and gas sent after the material combustion are few, are real environmental protection, cleaning, peace without any halogen during burning
Full cable.The requirement of standard GB 31247-2014 cables and optical cable combustibility B1 flame retardant ratings is reached, while can also meet
CPR B1 class requirements.
Insulating materials has reduction on price, and original is needed to reach the requirement of highest flame retardant rating, and general insulating materials is needed
FEP is wanted to insulate, and the application uses HDPE insulation, the 13 yuan/kg as long as conventional HDPE insulate, and FEP insulation needs 180
Unit/kg, so meets the requirement of burning, and the cost of material is greatly reduced again.
The cable is that A class flame retardant ratings are enhanced exoskeletal surpasses six classes, it is contemplated that the requirement of future transmission bandwidth, can be with
Support the various applications of ten thousand mbit ethernets and level below.Eliminate the cost of skeleton, former enhanced 6A product neededs high fire-retardance
Skeleton, and the flame-retardant reinforced exoskeletal six classes cable of A classes of the application production is exoskeletal, if to reach the product of A classes,
Skeleton is also required to meet the requirement of high fire-retardance, falls this makes it possible to the cost savings of high fire-retardance skeleton.Conductor 1 is set described in two
Into one so that cable is more firm.The external diameter of the restrictive coating 3 is 5.5 millimeters so that the reduction of the cost of restrictive coating 3.Original bone
The outer diameter sheath of frame needs to reach 6.5 millimeters, as long as and exoskeletal outer diameter sheath reaches 5.5 millimeters, so whole
Can reduce many on sheath material cost.
The composite mica tape of the use high-quality of belting layer 4, this composite mica tape has excellent resistance to elevated temperatures and resistance to burning
Performance.Coated using two-layer composite mica tape, it is contemplated that the wrapped phenomenon that leakage dew occurs in combustion, so the first cloud
Master tape layer using in the form of the outside of restrictive coating 3 directly longitudinal direction cladding, in the form of voluble wrapping put up by the second mica belt
Rate is 48-50% or so, and so the phenomenon of leakage dew would not occur in sheath in combustion, serve more preferable fire-retardant fireproof
Effect.
Braiding layer 5 weaves for glass fiber yarn, and the size of count and the quality of weaving quality directly affect product
Fire resistance, in order to preferably ensure the fire resistance of product, count reaches more than 95%, and in knitting process, selection is closed
The tension force of suitable plug die and Go-over mould and braided wires unwrapping wire, and the folding and unfolding line tension of cable core uniformity consistency
Must pay special attention to, so producing the braiding layer 5 from the preferable braider of domestic quality.
The step 1）Also include adding mould release between conductor and HDPE insulating barriers by mould release adding set.Should
Mould release adding set includes the dropping liquid part for setting gradually from top to bottom, upper strata application member, lower floor's application member and liquid collecting
Part, conductor is passed through between the upper strata application member and lower floor's application member；The upper strata application member includes will
Mould release is coated in the upper strata sponge of conductor top half, and for fixing the fixed mount of the upper strata sponge；The lower floor applies
Covering part includes being coated in mould release the lower floor sponge of conductor the latter half, and for supporting the support of the lower floor sponge
Box.By the mould release adding set can between conductor and HDPE insulating barriers coating release agent, prevent conductor exhausted with HDPE
Edge layer adhesion, is easy to electric wire to peel, and improves the insulation effect of electric wire, increases the service life of electric wire, again will not shadow
The healthy of operator is rung, is also prevented from polluting operating environment.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to design of the invention
It is defined with scope.On the premise of design concept of the present invention is not departed from, this area ordinary person is to technical side of the invention
The all variations and modifications that case is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
Through all recording in detail in the claims.
