Description
Technical field
The present invention relates to optical cable and manufacture method thereof, relate in particular to a kind of many Waveguides cable and manufacture method thereof of external force resistance.
Background technology
Many Waveguides cable of external force resistance often needs gasket for packing, and the optical cable gasket for packing is to fill up the interior room of cable core in the stranded process to make it keep a kind of element of rounding.Existing optical cable is the solid cord that the high density Insulation Material is extruded with the gasket for packing majority, because hardness is high, the extruding force that is subject in machine when being stranding into cable core altogether with other element is larger, limited high-speed production, and it is other elements such as loose sleeve pipe of extruding fiber unit easily, make the cable core distortion, affect the roundness of optical cable.Secondly, solid cord raw material consumption is large, and manufacturing cost is high, and himself weight is large, causes the optical cable transportation cost higher.Solid cord hardness is large in addition, and the external force resistance resiliency is poor, and the protection effect is not good enough.
Deficiency for optical cable hatching solid rope; foaming filling rope for optical cables arises at the historic moment; the advantages such as it is low because of raw materials cost, protection is effective, lightweight are extensively concerned; but relative less about the report of its manufacture method and market application at present; and such gasket for packing is very few especially with the data of particulate material, and exists problems.The patent of invention of a kind of " optical cable foaming packing gasket granule material and production method thereof " is disclosed such as CN101382626A, the raw material of packing gasket granule material has Low Density Polyethylene, high density polyethylene, polypropylene, Tissuemat E, stearic acid, calcium stearate and four pentaerythritol resins etc. in this patented technology, its component is more, proportional difference is larger, take by weighing trouble, be difficult for disperseing, difficulty mixes; And because each component unit price is all comparatively expensive, manufacturing cost still quite has pressure; In addition, the interpolation of multiple auxiliary agent uses easy final performance to product to produce harmful effect, causes goods air entrapment skewness, and can stay little molecule residue in the reproduced goods, affects the mechanical property of goods.
Summary of the invention
First purpose of the present invention provides a kind of many Waveguides cable of external force resistance, and it takes by weighing conveniently, saves manpower; Each component ratio is comparatively close, is easy to be uniformly dispersed; Only contain polyvinyl resin, calcium carbonate and nucleation masterbatch in the raw material, reduced the use of multiclass auxiliary agent to the harmful effect of the final performance of plastics; The interpolation of certain proportion calcium carbonate effectively reduces the cost of material; By the prepared foaming packing gasket body of this particle as buried layer, can combine closely with the plastic sheeting surrounding layer, thereby so that the filling degree of the degree of drying of gasket for packing and air is more constant, increase tension, the lateral pressure resistant intensity of gasket for packing, more be of value to it to the protective effect of light wave guide;
Second purpose of the present invention provides the manufacture method of many Waveguides cable of above-mentioned external force resistance.
For achieving the above object, the technical solution used in the present invention is: a kind of many Waveguides cable of external force resistance, described many Waveguides cable comprises several by loose sleeve pipe and is positioned at fiber unit, central reinforce member and several gasket for packings that loose sleeve pipe inner fiber forms that one restrictive coating coats described fiber unit, central reinforce member and several gasket for packings; Described foaming packing gasket granule material is comprised of the component of following weight portion:
40 ~ 60 parts of foamed material semi-manufacture,
40 ~ 60 parts of high density polyethylenes (first),
1 part of nucleation masterbatch;
Described foamed material semi-manufacture are comprised of the component of following weight portion:
Melt flow rate is 30 ~ 40 parts of the Low Density Polyethylenes of 0.03 ~ 0.09 g/10min,
Melt flow rate is 30 ~ 40 parts of the high density polyethylenes (first) of 1.8 ~ 3.2 g/10min,
Melt flow rate is 30 ~ 40 parts of the high density polyethylenes (second) of 5 ~ 9 g/10min,
15 ~ 20 parts in micron-class superfine calcium carbonate.
Above-mentioned foamed material semi-manufacture melt flow rate is 0.65 ± 0.20g/10min.
The above-mentioned preparation technology who is applied to the foaming packing gasket of optical cable may further comprise the steps:
Dry through blower fan again after step 3, the described rectangular process water cooling tank cooling with step 2, then, be cut into long 3mm, Ф 2.5mm small column grain as the foamed material semi-manufacture;
Step 5, described packing gasket granule material in extruder through heating and melting, simultaneously nitrogen is injected wherein under certain pressure, discharge gas through decompression again, thereby generate the uniform bubble of combining closely with internal layer, the formation frothing percentage is 10～80% polyethylene foam gasket for packing body buried layer;
Step 6, described polyethylene foam gasket for packing body buried layer are behind high speed extrusion under the temperature of setting, and its skin is after the PBT resin-coating, and behind the polyethylene foam gasket for packing that formation buried layer and clad are combined closely, stranding forms many Waveguides cable.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
1. many Waveguides of external force resistance of the present invention cable, its gasket for packing hardness is moderate, expansion coefficient is little, other deformed element around in the stranding process, being difficult for making, guarantee the cable core roundness, and because foaming packing gasket is softer, it is less to be that other element is stranding into the extruding force that is subject at device interior when cable core is extruded altogether, can high-speed production; Secondly, because little, the light specific gravity of foaming packing gasket density, so that the weight of unit length optical cable finished product, can reduce the transportation cost of optical cable; Again, the foaming packing gasket material consumption is few, can reduce manufacturing cost, the calcium carbonate unit price is relatively low, effectively reduced cost (although the use of calcium carbonate has increased the weight of gasket for packing self to a certain extent, but because gasket for packing is foaming packing gasket in this patent, still have greater advantage so compare the entity rope in weight); The component kind is relatively less, and its unit price is on the low side compared to each analog assistant, thereby whole manufacturing cost has greater advantage; Each proportion of composing difference is less, is convenient to take by weighing, and saves artificial.
2. many Waveguides of external force resistance of the present invention cable, its gasket for packing component ratio proportion difference is less, is convenient to take by weighing, and the manually-operated error is less, is beneficial to the stability that guarantees product quality during batch production; Secondly, do not contain each analog assistant, the use of each analog assistant easily produces harmful effect to the final performance of product, causes goods air entrapment skewness, and can stay little molecule residue in goods, affects Mechanical Properties of Products.
