Description
Technical field
The present invention relates to a kind of overlay film steel band more particularly to a kind of special overlay film steel bands of armoured cable.
Background technique
Composite steel-plastic belt is mainly used for communications optical cable, communication cable outer jacket, is bonded together composition synthesis with protective cover material
Sheath acts the moisture-proof layer for protecting cable core to corrode from moisture, while having armouring effect to cable core, resists extraneous effect
Power lay etc. in various applications for communications optical cable, communication cable and provides mechanical protection, guarantees the stability, reliably of application
Property.However, needing to realize fully stripped state between steel band and protective cover material when finished product cable is constructed, i.e., after stripping outer jacket, steel band covers
Also complete band removes film, only remaining base steel band.It is remained on armouring embossing base steel band if any overlay film after steel band and external sheath layer removing, just
It will affect electric conductivity.Because the optical cable is by will be after shield strips outside optical cable at the tower top section, steel band is directly filled with transmitting in cable
It sets earthed system to be welded, Lai Shixian conducting function, to cause the damage of the communications cable after avoiding base station from being struck by lightning.Such as
Fruit strips after sheath skin on base steel band also there are overlay film residual, just will affect the welding effect of steel band and tower top emitter.Cause
How this, provide a kind of direction that easily peelable overlay film steel band is made great efforts as those skilled in the art.
Summary of the invention
It is an object of that present invention to provide a kind of special overlay film steel band of armoured cable, which is making of special overlay film steel band
After optical cable, by its wrap up cable core from moisture corrode, while can by repeatedly bending still have good toughness and
It will not cracking, and plastic film is easy to completely strip with the sheath on the outside of it from steel band, is not in be torn, tear up
Situations such as.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of armoured cable special overlay film steel band, including steel

While tide, waterproof and weatherability, there is toughness and buckle resistance, guarantee that overlay film steel band after being made into optical cable, is wrapped up by it
Cable core is corroded from moisture, while still can have good toughness without cracking by repeatedly bending, and be added to second
2 ~ 6 parts of alkene acrylic copolymer, the bonding force of plastic film is increased, increases peel strength, it is embedding with hydrogenated styrene-butadiene
Section copolymer collaboration, reach plastic film be easy completely stripped with the sheath on the outside of it from steel band, and be not in by
Situations such as tearing, tearing up；In addition, 5 ~ 12 parts of acrylic resin are also added into its formula, so that hydrogenated styrene-butadiene is embedding
The strand of section copolymer is more soft, to further enhance the flexibility of plastic film, makes it in stripping process
It is not easy to break, it is easier to be removed from steel band.
2. the special overlay film steel band of armoured cable of the present invention, 2 ~ 5 parts of nanometer calcium carbonate are added in formula, while adding white
3 ~ 10 parts of dormant oil cooperations, plastic film obtained have better tearing strength, guarantee plastic film in the mistake removed with steel band
Cheng Buhui is torn；In addition, it is bis- [ethyl -3- (3,5- di-tert-butyl-hydroxy phenyl)] that 2,2- oxalyl amido-is added in formula
