Refer to Fig. 1, Fig. 1 is the structural representation of the screened film of the embodiment of the present invention, as Fig. 1 and shown, one embodiment of the present of invention provide a kind of screened film for cable, this screened film 1 can comprise: for shield electromagnetic interference and the metal level 11 as medium, metal level is for covering the outer by 2 of the conductor 3 of cable, metal level 11 is provided with the conductive layer 12 for shielding, and conductive layer 12 is provided with coordinate conductor 3 outer and is made conductive layer 12 and metal level not divide 11 not and the insulating barrier 13 of conductor 3 and external insulation by 2.
It should be noted that, metal level 11 can be used as the medium of power delivery and/or Signal transmissions in assist with cable.
Can find out, this screened film is actual is be formed by stacking by three-decker, the electromagnetic membrane finally formed seems it is still skim structure in appearance, can be cut to the banded screened film of various different in width according to application demand, to be adapted to the wire rod of different demand.
Therefore, screened film 1 in the embodiment of the present invention comprises to be located at the outer of conductor 3 to arrange metal level 11 on 2, this metal level 11 can be used as first time shielding and as medium, then cover one deck conductive layer 12 on the metal layer, the electromagnetic wave producing electromagnetic interference is being reflected by conductive layer 12 by the effect of this conductive layer 12 on the one hand, the electromagnetic wave transmission in conductive layer 12 entered in conductive layer 12 can produce decay on the other hand, thus eliminate electromagnetic interference by absorbing and reflecting, and electric current in conductive layer 12 layers also can be derived rapidly by conductive layer 12, thus eliminate interference, be equivalent to second layer shielding, finally a layer insulating 13 can be set on conductive layer, what this insulating barrier 13 can coordinate conductor 3 is made conductive layer 12 and metal level 11 relative to conductor 3 by 2 and is extraneously insulation outward, therefore by existing needs repeatedly the process of coated braiding become and only need once coated screened film can reach same or better effect, thus greatly reduce raw-material consumption, thus reduction production cost, due to the minimizing of technique, especially the process of the very low braiding of efficiency is removed, can also greatly enhance productivity, in addition due to without the need to operations such as plating, can not to environment.
As optionally, conductive layer 12 such as to comprise at the metallic of side's property conduction and the hybrid resin of bearing metal particle, and the ratio that metallic accounts for the quality of conductive layer is 5% to 90%.
Be understandable that, this conductive layer 12 is due to the metallic of side's property conductions such as employing, namely the conductive capability of this metallic in all directions is all identical, therefore this conductive layer 12 can make the induced current produced in conductive layer 12 derive along the direction of this conductive layer 12, thus elimination electromagnetic interference, be equivalent to form one deck screen outward at conductor, can stop and absorb electric wire oneself with extraneous produce electromagnetic wave.
It should be noted that, hybrid resin in this conductive layer 12 is got by the mixing of various kinds of resin material, hybrid resin in this conductive layer 12 is for fixing metal particle on the one hand, also be the carrier as metallic on the other hand, wherein, the ratio that metallic accounts for the quality of conductive layer 12 is 5% to 90%, present two aspects of this quality ratio variant, the first is different according to the difference of the metallic used, density due to different metal element is not identical, and the size of metallic is substantially identical size, therefore the quality ratio that in conductive layer 12, the metallic of same volume mark accounts for conductive layer 12 is different, the metallic that density is large can take can take under same volume more, it two is, because the demand of the performance of electromagnetic shielding is not identical, such as require higher capability of electromagnetic shielding, then metallic account for the ratio of the quality of conductive layer 12 will be higher, what reflect is exactly that distance between metallic in conductor layer 12 becomes nearer, electric conductivity is better, make the faster of electromagnetic wave attenuation, and when the requirement of capability of electromagnetic shielding is not very high, metallic accounts for the ratio of the quality of conductive layer 12 will be lower, distance between metallic can be farther, electric conductivity weakens relatively, electromagnetic wave attenuation speed is relatively slow, therefore, the ratio of the quality of the conductive layer that the metallic in this conductive layer 12 takies can adjust according to demand, but not in prior art, during capability of electromagnetic shielding as better in needs, coated braiding is carried out repeatedly with regard to needs, thus waste lot of materials and to due to a large amount of wire netting pollution on the environment problems, and because repeatedly coated braiding can make the flexibility of wire rod itself become non-constant, manyly require flexibility good and the good wire rod of capability of electromagnetic shielding adopts the mode of coated braiding to realize, and adopt the electromagnetic membrane of this programme, because thickness is very thin, it itself is also flexible material, can not impact the flexibility of wire rod, specifically adjust according to actual conditions, do not limit.
As optionally, the thickness of conductive layer 12 is 5 microns to 200 microns.
It should be noted that, the thickness affecting conductive layer 12 mainly contains two kinds of factors, the diameter of the wire rod that the first is coated is different, thickness is not identical, such as thinner wire rod, it is thinner that the thickness of conductive layer 12 can do, and for the thicker wire rod of diameter, in order to ensure the reliability of wire rod, need thicker to conductive layer 12 need to do thicker, it two is can thickness is different according to the difference of the electric conductivity of demand, the wire rod that demand electric conductivity is strong can adopt the conductive layer 12 that thickness is larger, thick conductive layer 12 has larger cross-sectional area, thus electric conductivity is also stronger, relative, the wire rod that electric conductivity demand is less and higher to wire rod softness requirements, then can select the conductive layer 12 that Thickness Ratio is less, specifically adjust according to actual conditions, do not limit.
As optionally, the metallic of the side's of grade property conduction comprises the metallic that among gold, silver, copper, nickel and aluminium, at least one is formed.
It should be noted that choosing of metallic can choose the metallic that conductive capability is stronger, can accomplish to be issued to identical electric conductivity in the situation that the ratio of metallic quality is relatively little; As chosen the one among the stronger gold, silver of conductive capability, copper, nickel and aluminium, certainly, also another mode can be adopted, namely metallic is skin is the coat of metal that conductive capability is strong, the metal that internal layer selects electric conductivity weak compared with the coat of metal, certainly need to change metal and the strong metal of conductive capability has good associativity, can reach to be better than and adopt the metal metallic selected of internal layer completely, specifically choose and can determine according to the requirement of the wire rod of the restriction of production cost and production.
As optionally, the thickness of metal level 11 is 10 microns to 100 microns.
Be understandable that, the thickness of this metal level is wire rod according to different-diameter and fixed, and gauge or diameter of wire is larger, can choose the larger metal level of thickness 11, gauge or diameter of wire is less, can choose the less metal level of thickness 11, different from the difference of actual wire rod, specifically do not limit.
As optionally, metal level 11 is the metallic film that among gold, silver, copper, nickel and aluminium, at least one is formed.
Be understandable that, due to needs conduct first time screen and as medium, therefore its electric conductivity is also important, therefore the material of this metal level 11 needs to choose from the stronger metal of electric conductivity, as selected the one among gold, silver, copper, nickel and aluminium, the alloy of at least two kinds among this several metal certainly also can be adopted.
As optionally, insulating barrier 13 is hybrid resin, and the thickness of insulating barrier 13 is 5 microns to 500 microns.
It should be noted that, this insulating barrier 13 1 aspect is as insulating material, make metal level 11 and conductive layer 12 and external insulation, can be used as the means regulating wire rod flexibility on the other hand, as wire rod requires that then the thickness of this insulating barrier 13 can be done is larger for time harder, thus make the hardness of wire rod higher, as wire rod require comparatively soft time, as long as when ensureing insulation effect, insulating barrier 13 can be done as far as possible thin thus minimum degree can affect the pliability of wire rod.
As optionally, the one side that metal level 11 is not relative with conductive layer 12 is also provided with the diaphragm 14 that thickness is 10 microns to 100 microns;
And/or,
The one side that insulating barrier 13 is not relative with conductive layer 12 is also provided with the diaphragm 14 that thickness is 10 microns to 100 microns.
Be appreciated that and be, because screened film 1 is after production completes, be not use immediately, therefore need to protect it, a kind of feasible method adds layer protecting film 14 in the superiors of screened film 1 or orlop, then when reeling screened film 1, the side with protective layer is wound on outside, thus before use screened film 1, enough protections can be carried out to it, simultaneously diaphragm 14 can certainly be all set in the superiors of screened film and orlop, thus the carrying out of screened film 1 is more comprehensively protected, diaphragm can be different according to the thickness of screened film 1 itself, time as thicker in screened film 1, diaphragm 14 can be relatively thicker, when screened film 1 is thinner, it is thinner that diaphragm 14 can do.
As from the foregoing, the thickness 10 microns to 100 microns of metal level 11 in the embodiment of the present invention, the thickness of conductive layer 5 microns to 200 microns, and the thickness of insulating barrier is 5 microns to 500 microns, therefore the thickness of screened film 1 is between 20 microns to 800 microns, thus the wire rod of most classification on the market can be covered, meet its demand for capability of electromagnetic shielding.At the thickness 10 microns to 100 microns in conjunction with upper and lower two-layer diaphragm 14, thus the maximum ga(u)ge of embodiment of the present invention product is 1000 microns, minimum thickness, when only having layer protecting film 14, is 30 microns.
All kinds of needs that the screened film 1 of the embodiment of the present invention can be widely used in the aspects such as electric power, communication and Signal transmissions carry out the electric wire shielded.
Fig. 2 is that of the screened film of the embodiment of the present invention implements illustration, as shown in Figure 2, the longitudinal section view of the wire rod produced for adopting the screened film 1 of the embodiment of the present invention, it is followed successively by conductor 3 from inside to outside, outer by 2, metal level 11, conductive layer 12, insulating barrier 13 and outer by 2, wherein metal level 11, conductive layer 12 and insulating barrier 13 are electromagnetic membrane 1, can find out, repeatedly cover wheat relative to prior art draw aluminium foil and arrange wire sheathing, greatly can reduce production cost and the equipment investment of wire rod, and greatly reduce wire production due to plating pollution on the environment.

It should be noted that, when generating metal level, also can a laminar substrate can be first set under metal level in advance, metal level is generated on the substrate, thus obtain the higher metal level of quality, be easy between this substrate and metal level depart from, the generation of such as metal level adopts founding, is then molded into the mode of demand thickness simultaneously.
302, evaporation or coating comprise the conductive layer of metallic and hybrid resin on the metal layer.
Wherein, after metal level completes, can will comprise the conductive layer of metallic and hybrid resin by the mode of evaporation or coating, the thickness of this conductive layer is determined by the demand of wire rod, and wherein, hybrid resin is mixed by multiple different resin material.
It should be noted that, adopt the mode of evaporation or coating, the conductive layer that containing metal particle and hybrid resin can be made to be formed is evenly distributed on metal level, thus which can just can the conductive layer of acquiring demand thickness by carrying out the condition of evaporation adjusting, thus the quality of the conductive layer not only formed is higher, and the efficiency forming conductive layer is also higher.
