Description
Technical field
The utility model relates to a kind of screened film, particularly relates to a kind of anticorrosion screened film being applied to coaxial cable.
Background technology
What is called shielding on the construction of cable is in fact the measure improving Electric Field Distribution.Cable conductor forms by stranded conductor is stranded, and easily form air gap between it and insulating barrier, conductive surface is rough, and electric field can be caused to concentrate.Add the screen layer of one deck semiconductive material at conductive surface, the conductor equipotential of it and conductively-closed, and with insulating barrier good contact, thus avoid, between conductor and insulating barrier, shelf depreciation occurs.This one deck shields, and is also called internal shield.In insulating surface and sheath contact position, also may there is gap, during cable bend, oil paper cable insulating surface easily causes crackle, and these are all the factors causing shelf depreciation.Add the screen layer of one deck semiconductive material at surface of insulating layer, the insulating barrier of it and conductively-closed has good contact, with protective metal shell equipotential, thus avoids, between insulating barrier and sheath, shelf depreciation occurs.
What traditional cable shielding film adopted is the semiconductor structure that two-layer aluminium foil layer sandwiched plastic layer is formed, and the shield effectiveness of this kind of screened film is poor, and when cable serving is damaged, screened film directly can be subject to extraneous corrosion, cause namely being corroded in the short time damage, have influence on the normal use of cable, limit the service life of cable.When especially relating to submarine cable, because the salinity of seawater is higher, the submarine cable moment is in the stronger environment of corrosivity, and its screened film is easy to be corroded, and has influence on the service life of submarine cable.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, proposes anticorrosion screened film.
The purpose of this utility model, will be achieved by the following technical programs:
Anticorrosion screened film, the pet layer comprising two-layer aluminium foil layer and be located between two-layer aluminium foil layer, all has adhesive layer between described pet layer and two-layer aluminium foil layer, and especially, the outside of described two-layer aluminium foil layer is coated with for corrosion-resistant acrylic acid anticorrosive coat.
Preferably, described acrylic acid anticorrosive coat thickness is 0.5 ~ 3 μm.
Preferably, described adhesive layer is glue curing layer.
Preferably, described acrylic acid anticorrosive coat is acryloid cement anticorrosive coat.
A kind of submarine cable applying described anticorrosion screened film, especially, in described submarine cable, there is coaxial cable, described coaxial cable comprises copper covered steel inner core from inside to outside, the PVC foam film of coated copper Baogang inner core, the anticorrosion screened film of parcel PVC foam film, socket pressure wrap up in the aluminum-magnesium alloy wire layer of anticorrosion screened film and the cable cover(ing) of outermost metallized aluminum Mg alloy wire layer.
Preferably, described coaxial cable comprises copper covered steel inner core from inside to outside, the PVC foam film of coated copper Baogang inner core, the anticorrosion screened film of parcel PVC foam film, socket pressure wrap up in the coated and cable cover(ing) of fixing anticorrosion screened film of the aluminum-magnesium alloy wire layer of anticorrosion screened film, the anticorrosion screened film of parcel aluminum-magnesium alloy wire layer and outermost.
The beneficial effects of the utility model are mainly reflected in:
Inside and outside traditional screened film, anticorrosive coat has all been set up in both sides, can protect the inner core of cable, prevents inner core from suffering erosion, and anti-corrosion property can be superior, extends the service life of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anticorrosion screened film of the utility model;
Fig. 2 is the structural representation of embodiment one coaxial cable;
Fig. 3 is the structural representation of embodiment two coaxial cable.
Detailed description of the invention
The utility model provides anticorrosion screened film, has the features such as corrosion-resistant, advantages of good shielding performance.
As shown in Figure 1, anticorrosion screened film, the pet layer 2 comprising two-layer aluminium foil layer 1 and be located between two-layer aluminium foil layer 1, pet layer is plastic layer, between pet layer 2 and two-layer aluminium foil layer 1, all there is adhesive layer 3, adhesive layer 3 is glue curing layer, and for bonding aluminum layers of foil 1 and pet layer 2, pet layer and two-layer aluminium foil layer form semiconductor structure.Wherein, the outside of two-layer aluminium foil layer 1 is coated with for corrosion-resistant acrylic acid anticorrosive coat 4, acrylic acid anticorrosive coat 4 thickness is 0.5 ~ 3 μm, acrylic acid anticorrosive coat has stronger corrosion resistance, the invasion and attack of external corrosion environments can be kept out, protect the inner core of cable, extend the service life of cable, acrylic acid anticorrosive coat is acryloid cement anticorrosive coat, the composition of acryloid cement at least comprises acrylic acid, alcohols solvent, pigment and plasticizer, wherein, acrylic acid has stronger antiseptic property, alcohols solvent comprises isopropyl alcohol, ethylene glycol etc., alcohols solvent plays the effects such as dilution, pigment is polymer waterborne pigment, it is the effects such as the viscosity of aqueous solvent that plasticizer increases acryloid cement, the acrylic acid anticorrosive coat mixed by above material has the resistance to performance such as anticorrosion, and acryloid cement is aqueous solvent, harmless.
Consider performance and the cost needs of anticorrosion screened film, the thickness of acrylic acid anticorrosive coat preferably adopts 1 ~ 2 μm, and the lower and performance of cost is protected.
Below the application of the anticorrosion screened film of the utility model in submarine cable:
Embodiment one, in submarine cable, there is coaxial cable, as shown in Figure 2, coaxial cable comprises copper covered steel inner core 6 from inside to outside, the PVC foam film 7 of coated copper Baogang inner core 6, the anticorrosion screened film of parcel PVC foam film 7, socket pressure wrap up in the aluminum-magnesium alloy wire layer 8 of anticorrosion screened film and the cable cover(ing) 9 of outermost metallized aluminum Mg alloy wire layer 8.
Embodiment two, as shown in Figure 3, coaxial cable comprises copper covered steel inner core 6 from inside to outside, the PVC foam film 7 of coated copper Baogang inner core 6, the anticorrosion screened film of parcel PVC foam film 7, socket pressure wrap up in the coated and cable cover(ing) 9 of fixing anticorrosion screened film of the aluminum-magnesium alloy wire layer 8 of anticorrosion screened film, the anticorrosion screened film of parcel aluminum-magnesium alloy wire layer 8 and outermost.
The coaxial cable of submarine cable inside can be effectively prevented to be corroded environmental assaults.
Certainly, anticorrosion screened film of the present utility model is also applicable to highway cable, electrical equipment inside cable, building cable etc.
