Description
The application is entitled：A kind of cable or optical cable are with CPP films and preparation method thereof, the applying date：2015 09
Month 23 days, Application No.：The divisional application of 2015106111303 patent of invention.
Technical field
The invention belongs to nylon material technical field, especially a kind of cable or optical cable CPP films and preparation method thereof.
Background technology
There is copper conductor or aluminium conductor or composite conductor in cable, conductor meeting accelerated oxidation after water is met, can influence to transmit electricity
Ability and accelerated ageing, make the lost of life；Therefore cable is needed with Prevention method.Core transmission element in optical cable is optical fiber,
Optical fiber is made by high-purity silicon dioxide wire drawing, and optical fiber can be made to have the micro-crack being invisible to the naked eye in pulling process,
Therefore optical fiber micro-crack under the erosion of moisture content can gradually increase, and can influence optical transmission performance, fibercuts can be caused when serious；For
This, blocking water for optical cable requires stricter.In the prior art, light, the mode that blocks water of cable are typically to use ointment additional nonwoven
The mode of cloth or waterstop or the PVC bands that block water is realized；However, due to non-woven fabrics or waterstop or the thickness for the PVC bands that block water
Generally in more than 0.3mm, although it can reach the function of blocking water, when by the way of wrapped using spiral, due to taking
Connect, therefore above-mentioned band carrys out at least 0.9mm external diameter contribution to cable tie.Applicant is in progress light, the function point of cable design
During analysis, by studying repeatedly, it is believed that, if having certain band that equally there is the effect that blocks water and can meet manufacturing technique requirent, when
When size is thinned, the material consumption and cost of cable can be significantly reduced, increases the competitiveness of product in market.According in this, Shen
The band meeting benchmark asked someone using thickness as 0.1mm, by taking the cable of 30mm diameters as an example, uses density as 1.45g/cm3Low cigarette
Halogen produces oversheath；It is computed, theoretical consume of only oversheath may be reduced by 41.41kg/km, in terms of 15 yuan/kg unit price,
About 621 yuan/km of escapable cost, in fact, except oversheath, as long as the material beyond band, can all have different degrees of
Save.With small micro-line cable enterprise, above-mentioned cable 1000km meters are produced every year, you can save about 620,000 yuan of cost, therefore, saving
It is more surprising.
Therefore, applicant is commercially seeked advice from, and have found the material with corresponding function, i.e., in the prior art
CPP film bands, however, applicant through use, it is found that it can not be competent at blocking water in electric wire completely, it is impossible to be used in criticize
Continuous production is measured, main cause has that low intensity, elongation at break are small, and low intensity prevents it wrapped in cable processing from being suitable for
Mechanism, easily it is broken when wrapped；Elongation at break is small so that easy pulling off strips material when speed of production changes, and actual cable production
In can usually change speed due to a variety of causes.
Beneficial improvement is carried out for CPP bands according in above-mentioned reason, applicant, to adapt to making for optical cable industry
With.

Antioxidant：1~3 part；
Second step：CPP films make：Core layer material is discharged from the head of the second extruding machine, and led to by the second conveying
Road S2 enters along second channel direction A2 in the second gap that second couple of cold roll L2 staggered relatively is formed, and forms sandwich layer 2；And
Sandwich layer is constantly drawn forwards；First that established sandwich layer is drawn and formed by first couple of cold roll L1 staggered relatively
Gap, then make heat-sealing layered material be discharged from the head of the first extruding machine, and by the first conveying passage S1 along first passage direction A1
In the first gap formed into first couple of cold roll L1 staggered relatively, and make hot sealing layer material position above sandwich layer, formed viscous
The hot sealing layer 1 being attached on sandwich layer, sandwich layer is collectively referred to as the first composite bed with hot sealing layer, and constantly draws the first composite bed forwards；
By the first composite bed by band turning device S4, make the sandwich layer in the first composite bed above, overturn first is answered
Layer traction and the third space formed by the 3rd couple of cold roll L3 staggered relatively are closed, then sided corona treatment layered material is squeezed from the 3rd
The head discharge of molding machine, and the 3rd pair of cold roll staggered relatively is entered along first passage direction A3 by the 3rd conveying passage S3
In the third space that L3 is formed, and make corona processing layer material position above sandwich layer, form the corona processing layer being adhered on sandwich layer
3, complete the making of cable or optical cable CPP films；Wherein:Core layer thickness：Corona processing layer thickness=1: (0.2~0.6),
The gross thickness of the CPP films is 0.06~0.12mm；Between the height ＞ first in the gaps of height ＞ second of the third space
The height of gap.
There is the present invention preparation method simply, easily to grasp；The advantages of raw material is easily purchased.
Cable or optical cable CPP films in the present invention, data below is obtained by test.
As can be seen from the above table, tensile strength >=80MPa of the cable in the present invention or optical cable CPP films, bending are strong
Degree >=120MPa, elongation at break >=65%, 200 DEG C of short-term stability ＞, 140 DEG C of long-time stability ＞；Therefore with preferable
Tensile strength, bending strength and larger elongation at break, preferable high-temperature stability, compared with prior art in waterstop,
For non-woven fabrics, the PVC bands that block water, tensile strength improves 115%, elongation at break compared with highest and carried compared with highest
High by 45%, therefore, the CPP films in the present invention can not occur to break with the vertical bag of existing cable or vertical chartered plane
Split；Used in existing optical cable indulge chartered plane tool and it is wrapped mechanical when, also do not occur phenomenon of rupture, therefore the present invention solves asking for fracture
Topic, and in higher speed（Speed-raising 35%）In the case of, phenomenon of rupture does not also occur；Because the gross thickness of CPP films is
0.06~0.12mm, and the minimum thickness of waterstop, non-woven fabrics, the PVC bands that block water is 0.3mm, therefore, can be reduced after wrapped
0.5~0.7mm cable diameters, can be significantly cost-effective, increases competitiveness.
The block-water performance of CPP films in the present invention is suitable with waterstop of the prior art, the PVC bands that block water, and compares nonwoven
The block-water performance of cloth is more excellent.
In the embodiment 2 of the present invention, add silver powder so that sandwich layer it is conductive can, therefore the CPP films not only can be with
Block water, and the function of shielding can be realized, with the cable when, more materials and process can be saved and consumed.
Therefore, the present invention has the beneficial effects such as mechanical strength is higher, elongation at break is bigger, high-temperature stability is more preferable.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that design of the invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
