The present invention relates to the optical cable reinforcement, relate in particular to the vertical packaging material material of optical cable, particularly a kind of optical cable is with indulging bag glass fibre reinforcing band.
Background technology
In the prior art, non-metallic optical fiber cables adopts the tubular FRP (fiberglass reinforced plastics) of rigidity as its reinforcement usually, its structure is a layer-twisted type or skeleton, the optical cable of layer-twisted type and skeleton construction all needs to consume more cable material, and is higher by 30%～40% than central beam tube type optical cable cost; Traditional central beam tube type optical cable is placed waterstop or water blocking yarn outside loose sleeve pipe, vertical again Baogang plastic composite strip, parallel placement phosphatization steel wire in sheath at last; In addition, inside cable adopts fragrant human relations as reinforcement usually, but the price comparison costliness of fragrant human relations.
Summary of the invention
Technical problem of the prior art to be solved by this invention is: now in the technology, non-metallic optical fiber cables adopts the tubular FRP (fiberglass reinforced plastics) of rigidity as its reinforcement usually, its structure is a layer-twisted type or skeleton, the optical cable of layer-twisted type and skeleton construction all needs to consume more cable material, and is higher by 30%～40% than central beam tube type optical cable cost; And traditional central beam tube type optical cable is placed waterstop or water blocking yarn outside loose sleeve pipe, vertical again Baogang plastic composite strip, and parallel placement phosphatization steel wire in sheath owing to adopt ferrous material, has the possibility of oxidation liberation of hydrogen at last; Again because of in sheath, placing parallel steel wire, jacket thickness is increased, optical cable Heavy Weight, physical dimension are big; In addition, inside cable adopts fragrant human relations as reinforcement usually, but the price comparison costliness of fragrant human relations, optical cable cost height.
The present invention provides a kind of non-metal reinforcing band capable of packaging optical cable vertically for solving the technical scheme that the problems referred to above adopted that exists in the prior art, composition and PUR by complex root fiber and hot setting adhesive or hot setting adhesive and thermoplastic adhesive constitute, and described hot setting adhesive or hot setting adhesive and thermoplastic adhesive's composition becomes the bag the indulged shoestring with certain toughness, hardness and tearing strength the complex root fiber is bonding.The bearing of trend of described complex root fiber with described indulge the bag shoestring bearing of trend identical, described indulge the bag shoestring cross section rectangular or approximate rectangular, the described bag shoestring of indulging is provided with a PUR coating in the surface of a side at least, the described thickness of indulging the bag non-metal reinforcing band is between 0.2mm～6mm, and the described width of bag non-metal reinforcing band of indulging is between 2mm～120mm.
Further, described complex root fiber is evenly distributed in the described adhesive.
Further, described adhesive is made up of two or more adhesive mixing.
Further, described adhesive is inorganic adhesive or organic adhesion agent, or natural adhesive or synthetic adhesive, or resin adhesive or rubber adhesive or compound adhesive, or thermoplastic adhesive or hot setting adhesive.
Further, described adhesive is made up of two-layer or two-layer above adhesive, and wherein one deck is hot setting adhesive or hot setting adhesive and thermoplastic adhesive's a mixture, and another layer is the thermoplastic adhesive.
Further, described adhesive is made up of three layers of adhesive, and wherein Zhong Jian one deck is hot setting adhesive or hot setting adhesive and thermoplastic adhesive's a mixture, and other are two-layer to be the thermoplastic adhesive.
Further, the interface between described each layer adhesive is parallel with the described band shape surface of indulging.
Further, described complex root fiber can be glass fibre or fragrant human relations or other fiber formation that has high elastic modulus, hangs down elongation at break, also can be their mixing.Glass fibre preferably.
Further,
Further, the quantity of described complex root fiber is at least 2.
Further, indulge in the cross section that wraps non-metal reinforcing band described, the area sum of the cross section of described complex root fiber accounts for described 80%～97% of the bag non-metal reinforcing band cross-sectional area of indulging.
Operation principle of the present invention is: in optical cable processing, outside optical fiber or loose sleeve pipe or cable core, directly the present invention is indulged bag, directly squeeze oversheath again, utilize described sheath heat to make the present invention form the pipe of a sealing, play and strengthen and the lateral pressure resistant effect.
The present invention and prior art compare, and its effect is actively with tangible.The outdoor optical cable that utilizes the present invention to produce, its structure can be that central beam tube type also can be a layer-twisted type, and its kind belongs to non-metallic optical fiber cables, and cost has reduced by 30%～40%.In addition, compare,, do not have the problem of iron oxidation liberation of hydrogen because of there not being ferrous materials such as steel wire, steel band in the optical cable with traditional central beam tube type optical cable; The cryogenic property of optical cable is good, low temperature can not occur and shrink; Use at multi-thunder area, avoided thunderstruck possibility.Simultaneously, physical dimension is little, in light weight.With regard to non-metallic optical fiber cables, it is nearly 70% that the optical cable that adopts the present invention to produce, cross-sectional area dwindle, weight saving nearly 50%; Compare the optical cable that adopts the present invention to produce with traditional central beam tube type optical cable; It is nearly 60% that cross-sectional area dwindles, weight saving nearly 60%.And, need not to add other material water-proof material, the optical cable infiltration test is qualified.The inside cable of producing like this, because of need not fragrant human relations, cost be low by about 30%, and the external form of optical cable is rounding more.
