Abstract
The utility model relates to a super-high-strength reinforced core with a protective layer. The super-high-strength reinforced core comprises a fiber bundle body; a curing adhesive layer is arranged outside the fiber bundle body; and a protective layer is arranged outside the curing adhesive layer. According to the above-mentioned structure, the super-high-strength reinforced core has a small bending radius and a good anti-folding performance. The tensile strength-resistant performance is twice as good as that of the reinforced core component made of aramid fiber materials. The installation, construction and laying of optical cables with the cores can be carried out conveniently; and the service life is long.
Description
Technical field
The utility model relates to a kind of strengthening core, relates in particular to a kind of superhigh intensity strengthening core with protective seam.
Background technology
Develop rapidly along with society; People increase the dependence of communication network and information transmission day by day, and communication network develops to high capacity and high density direction, in case destroyed; Can suffer serious economy loss immediately; Make troubles for our life, thereby should take certain measure that optical cable is protected and strengthen improvement, guarantee the long-term unimpeded and reliability of communication network optical cable.
Present optical cable product generally includes cable core and the peripheral sheath two parts of cable core, and its tensile force that in use usually can run into optical cable cable body is low, creasing resistance is poor, very easily causes fibercuts in the cable body and the transmission of interrupting information.
Because the formation Main Ingredients and Appearance of cable core optical fiber is a high-purity quartz glass; Its stretch-proof, anti-tortuous physical property be fragility very; Thereby ordinary optical cable very easily causes the fibercuts in the sheath in using installation process, and this also is the major obstacle that influences optical cable popularization and application to the family for many years.Industry is in order to overcome above-mentioned shortcoming; A lot of effort have been done; Comprise the optical cable of having invented the aramid fiber strengthening core protection that is added with the replacement spun glass of using on the present market in the optical fiber both sides, the main composition of this aramid fiber strengthening core be a kind of be that matrix reinforcing material, thermoset epoxy resin are that reinforcing core member, thermoplastic are in polyolefin jacket with the aramid fiber.Its aromatic polyamide optical cable reinforcing core promptly is to adopt above-mentioned structure; Its diameter is approximately 0.5MM-0.8MM, and this aromatic polyamide optical cable reinforcing core can improve the integrally stretching intensity of optical cable to a certain extent, guarantees that optical cable high-tension performance owing to the aramid fiber in the cable body in construction and use is difficult for being broken; Thereby protected not easy fracture of the optical fiber in the optical cable; But this aromatic polyamide optical cable reinforcing core is because its quality of thermoset epoxy resin technology is hard, but very very easily jackknifing of fragility, thereby fracture resistance is poor.When in construction, running into situation such as knotting, bending, extruding, above-mentioned aramid fiber strengthening core still can not effectively be protected the optical fiber in the cable protecting body.Analyze its chief reason: optical fiber the bending breaks the R angle less than 1 millimeter; Two parallel strengthening cores in its sheath are also fracture simultaneously when the doubling of optical cable angle and curved; Because the inside cable sectional dimension is little, cable body sheath elastic force is not enough, can't recover straightened condition rapidly; Thereby cause the fibercuts in the cable body; Its major function of aramid fiber strengthening core in the existing general employed house wiring optical fiber cable is for strengthening the tensile force of cable body, prevents that optical cable from pullling fracture, but its deadly defect is that (less than 30 millimeters) very easily rupture and lose again straight elasticity when bending radius is too small.Therefore, existing aromatic polyamide optical cable reinforcing core still can't overcome shortcomings such as its creasing resistance is poor, bending angle is little.
It is to use that the strengthening core of producing does not have external protection, and directly use can receive the interference of veiling glare, the comparison of wearing out during use.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of superhigh intensity strengthening core with protective seam to be provided, and is can bending radius little, anti-folding; Tensile resistence is two times of aramid fiber material reinforcing core member; And proportion is little, and weight is slim and graceful, and is counter-bending anti-folding.Applied optical cable installation is laid very convenient, long service life.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of superhigh intensity strengthening core with protective seam, said a kind of fibrous bundle body, the external curing glue-line that is provided with of fibrous bundle, the said curing glue-line peripheral hardware matcoveredn of comprising.
Preferably, said fibrous bundle body is a superhigh molecular weight polyethylene fibers bundle body.
Preferably, said fibrous bundle body is 0.5mm-0.8mm with the matrix diameter that solidifies the glue-line composition.
Preferably, said protective seam is that the flame-retardant high-elasticity property material of high rigidity bend resistance is processed.
Preferably, said protective layer thickness is 0.1mm-3mm.
Preferably, the fiber number of said fibrous bundle body is the 500-30000 fiber number.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of superhigh intensity strengthening core with protective seam of the utility model scheme comprises that superhigh molecular weight polyethylene fibers is provided with the curing glue-line outward, solidifies glue-line and is coated with the protective seam of being processed by the flame-retardant high-elasticity property material of high rigidity bend resistance; It is little that it has bending radius, anti-folding, as be applied in the manufacturing of undersized (3mm-5mm) inside cable; Its tensile resistence is two times of aramid fiber material reinforcing core member; And proportion is little, and weight is slim and graceful, and is counter-bending anti-folding.Applied optical cable installation is laid very convenient, long service life.Because the excellent material physical property of superhigh molecular weight polyethylene fibers is outstanding, be the upgraded product of present domestic alternative import aramid fiber optical cable stiffener.
