Summary of the invention
For the deficiency that prior art exists, the invention provides that a kind of intensity is high, the life-span is long, electrical insulation capability is good, chemical stability, resistance to creep and moisture pick-up properties is excellent, raw material sources are wide, quantity is unrestricted, cost is low novel basalt fiber yarn strengthen optical cable and manufacture method thereof.
To achieve these goals, the present invention realizes by the following technical solutions:
Optical cable strengthened by a kind of novel basalt fiber yarn, comprise some optical fiber and oversheath, optical fiber outer jacket described in it has Loose tube, fine cream is filled in Loose tube, multiple Loose tube and gasket for packing are arranged around central reinforce member, Loose tube and gasket for packing outer cladding basalt fibre reinforcing band, basalt fibre reinforcing band outer cladding oversheath, factice for filling in described basalt fibre reinforcing band.
Optical cable strengthened by above-mentioned a kind of novel basalt fiber yarn, and the oversheath described in it adopts fire proofing to extrude.
Strengthen a manufacture method for optical cable for the production of novel basalt fiber yarn, it comprises the following steps:
(1) optical fiber screening: select the optical fiber that transport property is excellent, tension force is qualified;
(2) cover of high-modulus, high strength, lower shrinkage polymkeric substance is adopted to mould technological forming sleeve pipe;
(3) cover is moulded: be wrapped in by sleeve pipe outside above-mentioned qualified optical fiber, and in sleeve pipe, fill fine cream;
(4) by sleeve pipe and central reinforce member qualified by layer-twisted type Structural assignments after be processed into cable core through cabling process;
(5) at cable core outer cladding basalt fibre reinforcing band, and in basalt fibre reinforcing band factice for filling;
(6) oversheath extruding high-modulus outside basalt fibre reinforcing band obtains basalt fibre yarn and strengthens optical cable;
(7) optical cable is strengthened to basalt fibre yarn and carry out full performance test, qualified encapsulation outbound.
The manufacture method of optical cable strengthened by above-mentioned a kind of novel basalt fiber yarn, and the step (1) described in it is screened qualified optical fiber and adopted the whole chromatogram of standard to carry out colored indicator.
Beneficial effect:
The present invention adopts novel basalt fiber yarn to instead of traditional nonmetal reinforcing fibre, because the intensity of basalt fibre yarn is higher, the effect of tolerated activity medium is excellent, the performance of the aspects such as resistance to creep and hydroscopicity is good, therefore tension specific strength of the present invention is high, moisture pick-up properties is excellent, creep resistance is splendid, possesses excellent resistance to active medium effect, guarantee the normal service life that optical cable is permanent, and the raw material sources of basalt fibre and goods is wide, processing technology does not have very large energy requirement, continuation and stability strong, the extensive sustainable user demand of optical cable can be met, meet the policy of national sustainable development, indoor and outdoor optical cable is highly suitable for as reinforcement.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
Embodiment 1
With reference to Fig. 1, the present invention includes some optical fiber 1 and oversheath 2, optical fiber 1 overcoat has Loose tube 3, fine cream 4 is filled in Loose tube 3, multiple Loose tube 3 and gasket for packing 5 are arranged around central reinforce member 6, Loose tube 3 and gasket for packing 5 outer cladding basalt fibre reinforcing band 7, basalt fibre reinforcing band 7 outer cladding oversheath 2, factice for filling 8 in described basalt fibre reinforcing band 7.
As further improvement, when the present invention needs flame retardant effect, oversheath can adopt fire proofing PVC or LSZH to extrude.
Manufacture method of the present invention, comprises the following steps:
(1) optical fiber screening: select the optical fiber that transport property is excellent, tension force is qualified;
(2) cover of high-modulus, high strength, lower shrinkage polymkeric substance is adopted to mould technological forming sleeve pipe;
(3) cover is moulded: be wrapped in by sleeve pipe outside above-mentioned qualified optical fiber, and in sleeve pipe, fill fine cream;
