Abstract
The utility model relates to a semi-gloss smooth metal-plastic composite tape for manufacturing optical cables. A plastic film is arranged on one side or two sides of a base tape, and the plastic film has a sub-gloss smooth coarse surface with a roughness Ra of 2.65 mum to 3.417 mum. The semi-gloss smooth metal-plastic composite tape has the advantages that the roughness of the plastic film surface is selected scientifically to reduce the sliding friction coefficient between the composite tape and a longitudinal covering mold and between the composite tape and a diameter-constant mold while wrapping an optical cable through the two molds, so as to achieve good cable effect and ensure the wrapping quality of the composite tape; the lapping joint of adjacent composite tapes has reliable and stable sealing effect after wrapping the optical cable so as to achieve good dampproof and waterproof effect and good shielding effect; and the scientific range of the roughness can prevent adhesion between the plastic film and a composite roller during the combination process, so as to ensure the peeling strength and prevent self-adhesion between adjacent composite tapes or collapse of the composite tape coil, thereby ensuring the normal use of the composite tape coil.

Summary of the invention
Purpose of design: on the basis of background technology, design a kind of span 2.65 μ m～3.417 μ m of honed smooth metallic plastic cladding strip surface roughness, when honed smooth metallic plastic cladding strip wraps mould, sizing mould by optical cable is vertical, the coefficient of sliding friction is little, stranding speed is fast, the mechanical performance loss of honed smooth metallic plastic cladding strip is few, the aging minimum of reducing to of secondary honed smooth metallic plastic cladding strip plastic foil simultaneously, improves the quality of honed smooth metallic plastic cladding strip and the quality and the life-span of optical cable.
Design: in order to realize above-mentioned purpose of design.The roughness Ra of honed smooth metallic plastic cladding strip (hereinafter to be referred as composite band) Central Asia light smooth type matsurface is chosen in 2.65 μ m～3.417 mu m ranges, is major technique feature of the present utility model.The purpose of doing like this is: the applicant finds in the test that lasts more than 2 years, whether the scope that composite band plastic foil surface roughness is selected science, the one, whether the quality that is directly connected to composite band is reliable, the 2nd, the roughness that is directly connected to the composite band surface is being wrapped mould by indulging, whether the coefficient of sliding friction during the sizing mould is minimum, the 3rd, the roughness that is directly connected to the composite band surface is being wrapped mould by indulging, during the sizing mould whether easily by and the mechanical performance that can not injure composite band destroy the overall structure and the technique effect of composite band, be embodied in:
1, the size of the coefficient of sliding friction of the composite band that is directly connected to manufacturing the time and the molding effect of compound coating by vertical bag mould, sizing mould.When roughness during less than its span, the roughness of composite band face approaches planar, its coefficient of sliding friction increases, composite band is by vertical bag mould, sizing mould the time, owing to almost be face and contact with vertical bag mould, sizing mould, therefore frictional resistance increases, and not only easily pulls the plastic foil of composite band face, and has reduced the peel strength between plastic foil and base band; When roughness greater than its span, increased the thickness of composite band zone face plastic foil inevitably, and the increase of composite band zone face plastic foil thickness, not only increased the manufacturing cost of composite band, and make composite band wrap mould by indulging, during the sizing mould, because the thickness of composite band plastic foil is thick and be elasticity, and the roughness that is positioned at composite band plastics thick film surface is being wrapped mould by indulging, during the sizing mould, certainly will be by the chamber wall extruding of the chamber wall of sizing mould or vertical bag mould, friction, forcing the roughness that is positioned at thick film surface that wearing and tearing take place inevitably comes off or is out of shape, its wearing and tearing come off or the degree of being out of shape almost forms dynamic plane once more with the face that is positioned at roughness, this dynamic plane can make the roughness on composite band plastic foil surface lose coarse level and smooth function, the residual plastic powders mould that can block up, increased composite band on the contrary and wrapped mould by indulging, contact area during the sizing mould, increased frictional resistance, and this frictional resistance has destroyed the combined strength bination between plastic foil and base band inevitably, reduce the peel strength of composite band, and destroyed the mechanical performance of composite band.
2, be directly connected to the coating quality of honed smooth metallic plastic cladding strip to optical cable.Because optical cable coats the quality of quality, not only and the peel strength size between composite band face plastic foil and base band direct relation is arranged, and direct relation is arranged with composite band face plastic foil whether intact.As described in above-mentioned 1, the composite band plastics face coefficient of sliding friction big and little, in the manufacture process of composite band, though depend on the roughness of composite band face, but the roughness of composite band plastics face was selected not at that time, not only can reduce the peel strength of composite band, i.e. peel strength between plastic foil and base band, and can damage plastic foil, as plastic foil pulled, drawn back, state such as the part tears.States such as this plastic foil is pulled, drawn back, the part tears have directly influenced the sealing effectiveness of composite band and composite band overlap joint mouth after coating, do not have protection against the tide, good waterproof effect, directly influence the quality of its shielding.
3, be directly connected to the viscosity and the stability of band and interband after the composite band rolling.Find in test, when the span of composite band plastic foil surface roughness Ra surpasses 2.65 μ m～3.417 mu m ranges, will produce two kinds of phenomenons:
When span during less than 2.65 μ m, roll banding easily in the production composite band process reduces peel strength, easily produces self-adhesion between composite band after the rolling and composite band, causes the composite band distortion, directly has influence on the normal use of composite band.
When span during greater than 3.417 μ m, composite band after the rolling and the gap between composite band increase, the poor stability of rolling, easily take place to roll up the phenomenon of collapsing, not only directly have influence on the stability of composite band rolling, and directly influence the normal use of coiled composite, simultaneously, in the process of vertical bag mould and the coating of sizing mould stranding, make plastic foil wearing and tearing, dry linting easily, block up, make and play bag in the cable jacket process easily, cause the optical cable quality to descend.
Technical scheme: honed smooth metallic plastic cladding strip, the base band one or both sides are equipped with plastic foil, and described plastic foil is the rough matsurface of inferior light smooth type, and the roughness Ra of its matsurface is 2.65 μ m～3.417 μ m.
The utility model is compared with background technology, the one, the science of composite band plastic foil surface roughness is selected, make composite band by vertical bag mould, when the sizing mould coats optical cable, and the coefficient of sliding friction that produces between vertical bag mould, the sizing mould is little, it is effective to coat the resulting stranding in back, has guaranteed the quality that composite band coats optical cable; The 2nd, behind the coating optical cable, the sealing effectiveness of the overlap joint mouth of composite band and composite band is reliable and stable, not only moistureproof, good water-proof effect, and also the effect of shielding is good; The 3rd, because roughness span science has been avoided plastic foil and composite roll roll banding phenomenon in the recombination process, guaranteed peel strength, avoided the self-adhesion between composite band and composite band again or the volume phenomenon of collapsing, guaranteed the normal use of coiled composite.
