Abstract
The utility model discloses a kind of optical cable glass fiber tapes.The utility model includes glass fibre, FRP bar and polyurethane adhesive, it is characterized by: the polyurethane adhesive is glass fibre and FRP bar bonding at a shoestring, the extending direction of the glass fibre and FRP bar is identical as the extending direction of shoestring, the cross section of the shoestring is in rectangle or approximate rectangular, the shoestring all contains polyurethane coating, the thickness of the optical cable glass fiber tape is between 0.3mm~5.5mm, and the width of the optical cable glass fiber tape is between 3~300mm.The utility model solves in the prior art the technical issues of non-metallic optical fiber cables are at high cost, weight is heavy, structure size is big and ordinary optical cable iron oxidation liberation of hydrogen.
Description
Technical field
The utility model relates to the reinforcement technologies of optical cable, and in particular to a kind of optical cable glass fiber tape.
Background technique
It is general using steel wire etc. to there is the metal compared with high-tensile to be reinforced in common cable, to increase cable
Tensile property cannot reinforce its tensile property using metal due to the particular/special requirement of use environment, especially optical cable, only
The tensile property of cable can be increased using nonmetallic materials.
Currently used nonmetallic tensile materials are that aramid fiber and glass fibre are since the price of aramid fiber is extremely expensive
The manufacturing cost of cable is reduced, more and more cable manufacturers begin to use the lower glass fibre of price to carry out cable
Reinforce, but what conventional glass fiber bundle was all made of monofilament disperse, independent, it is very easy to occur in use disconnected
It splits, directly results in the tensile strength decline of cable；Simultaneously because the glass fiber single filament of fracture produces in entire glass fiber bundle
On the one hand setation silk be easy to cause operator to be stabbed；On the other hand the broken fibre of aerial glass fibre that splashes also is easy
It is sucked by people, damages the health of operator, these disadvantages result in glass fibre and can not produce and use in large quantity, replace
Aramid fiber is as main nonmetal cable reinforcement material.
Therefore, it is necessary to be improved existing glass fiber tape completely.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of optical cable glass fiber tape, described
Optical cable solve in the prior art that non-metallic optical fiber cables are at high cost, weight weight, structure size are big and common with glass fiber tape
Optical cable iron aoxidizes the technical issues of liberation of hydrogen.
To achieve the above object, the technical solution of the utility model is: a kind of optical cable glass fiber tape, including
Glass fibre, FRP bar and polyurethane adhesive, it is characterised in that: the polyurethane adhesive is bonded glass fibre and FRP bar
At a shoestring, the glass fibre and the extending direction of FRP bar and the extending direction of shoestring are identical, the shoestring
Cross section is in rectangle or approximate rectangular, and the shoestring all contains polyurethane coating, the optical cable glass fibre
The thickness of band is between 0.3mm~5.5mm, and the width of the optical cable glass fiber tape is between 3~300mm.
Preferably, the glass fibre is several glass fibres being evenly distributed in polyurethane adhesive.
Preferably, in the cross section of the glass fiber tape, the sum of described area of cross section of glass fibre is accounted for
The 85%~95% of the cross-sectional area of the glass fiber tape.
Preferably, interweave or periodically interweave between several glass fibres.
Preferably, the FRP bar is several FRP bars being evenly distributed in polyurethane adhesive.
Preferably, interweave or periodically interweave between several FRP bars.
Preferably, interweave or periodically interweave between the glass fibre and FRP bar.
The beneficial effects of the utility model are:
This product and the prior art compare, and effect is actively and it will be evident that the room produced using the utility model
Outer optical cable, structure can be central beam tube type and be also possible to layer-twisted type, and type belongs to non-metallic optical fiber cables, and cost is dropped
It is low；In addition, being compared with traditional central-beam tube type fiber optic cable, because there is no the metal materials such as steel wire, steel band, aluminium strip in optical cable, do not deposit
The problem of iron aoxidizes liberation of hydrogen and survey more anti-than aluminium strip pressure is stronger；The cryogenic property of optical cable is excellent, is not in low-temperature shrink；?
Multi-thunder area uses, and avoids thunderstruck possibility；Meanwhile small, light-weight, the easy construction of the diameter of optical cable；With regard to non-metallic optical fiber cables
For, the optical cable produced using this product is compared with conventional center beam tube type cable, reduced cross-sectional area, weight saving；And
And without adding other material water-proof materials, optical cable infiltration test is qualified, the inside cable produced in this way, because not having to fragrant human relations, cost
It reduces, and the external form of optical cable also more rounding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model cross section.
In figure: 1-glass fibre, 2 one polyurethane adhesives, 3-FFRP bars.
Specific embodiment
The utility model and its specific embodiment are described in further detail with reference to the accompanying drawing.
Referring to Fig. 1-2, the utility model includes glass fibre, FRP bar and polyurethane adhesive, it is characterised in that: described
Polyurethane adhesive glass fibre and FRP bar bonding at a shoestring, the extending direction of the glass fibre and FRP bar with
The extending direction of shoestring is identical, and the cross section of the shoestring is in rectangle or approximate rectangular, and the shoestring all contains
Polyurethane coating, the thickness of the optical cable glass fiber tape is between 0.3mm~5.5mm, the optical cable glass
The width of glass fiber band is between 3~300mm.
Preferably, the glass fibre is several glass fibres being evenly distributed in polyurethane adhesive.
Preferably, in the cross section of the glass fiber tape, the sum of described area of cross section of glass fibre is accounted for
The 85%~95% of the cross-sectional area of the glass fiber tape.
Preferably, interweave or periodically interweave between several glass fibres.
Preferably, the FRP bar is several FRP bars being evenly distributed in polyurethane adhesive.
Preferably, interweave or periodically interweave between several FRP bars.
Preferably, interweave or periodically interweave between the glass fibre and FRP bar.
The working principle of this product is: optical cable processing in, outside optical fiber or Loose tube or cable core, directly by this product into
Row longitudinal wrap, then oversheath is directly squeezed, so that this product and sheath is formed the entirety of a sealing using the sheath heat, rises and add
The effect of strong and lateral pressure resistant.
