Description
Technical field
The utility model relates to a kind of composite material, particularly relates to a kind of copper foil tape for electromagnetic shielding.
Background technology
Along with the arrival of digital age, the electronic products such as such as notebook computer, palmtop PC, mobile phone, photocopier enter into huge numbers of families, but these products can produce noise because of high-frequency electromagnetic wave interference, affect using character.If human body long term exposure in powerful electromagnetic after the match, then possibility easily cancer stricken pathology, therefore anti-electromagnetic interference has been imperative.Shielding is exactly to the isolation carrying out metal between two area of space, to control electric field, magnetic field and electromagnetic wave by a region to the induction in another region and radiation.Concretely, be surrounded with the interference source of shield by component, circuit, sub-assembly, cable or whole system exactly, prevent interfere with electromagnetic field to outdiffusion; Or with shield, receiving circuit, equipment or system are surrounded, prevent them to be subject to the impact of external electromagnetic field.
Copper Foil is the high performance electromagnetic shielding material of a class, is used for preparing all kinds of metallic shield adhesive tape.But in the existing market demand, except meeting basic shielding function solenoid, the outward appearance of shielding material also needs to match with electronic product, and how producing the adhesive tape product not only having excellent electromagnetic function of shielding but also can match with the appearance requirement of electronic product becomes the focus that Ge Jia enterprise falls over each other to study.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of thickness is thin, lightweight, the composite copper foil belt of diverse in function, it had both had excellent electro-magnetic screen function, its outward appearance diversity requirements can be met again, the place needing electromagnetic shielding in the various electronic products such as all kinds of transformer, mobile phone, computer, PDA, PDP, LCD display, notebook computer, photocopier can be widely used in.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of copper foil tape, is provided with printing pet layer, ink layer, composite layer, nickel screen layer, copper foil layer, pressure-sensitive adhesive layer and release film layer from top to bottom successively, and wherein, the one side near described pressure-sensitive adhesive layer in described copper foil layer is provided with honeycomb groove.
Preferably, described copper foil tape, the thickness of described printing pet layer is 4 ~ 6 μm.
Preferably, described copper foil tape, the thickness of described ink layer is 1 ~ 2 μm.
Preferably, described copper foil tape, the thickness of described composite layer is 5 ~ 15 μm.
Preferably, described copper foil tape, described nickel screen layer is honey comb structure.
Preferably, described copper foil tape, the thickness of described copper foil layer is 5 ~ 10 μm.
Preferably, described copper foil tape, the thickness of described pressure-sensitive adhesive layer is 10 ~ 20 μm.
The beneficial effects of the utility model are: 1) adopt printing level PET as cladding material, both ensure that the appearance brightness of product, and made again ink easily be coated with, thus improve the distribution consistency degree of ink; 2) ink layer is set and both can have reached the heat insulation effect of shading, the diversity requirements to product appearance can be met again; 3) Copper Foil with low surface oxidation characteristic is adopted, and in its one side near pressure sensitive adhesive, honeycomb groove is set to increase contact surface area, on the basis ensureing product effectiveness, improve the adhesive force of Copper Foil and pressure-sensitive adhesive layer further, ensure the structural stability of product; 4) increase the shielding ability of product by setting up honeycomb nickel screen, simultaneously honey comb like structure can be held adhesive and bonds through nickel screen and Copper Foil, ensure that the adhesion stability of composite layer, nickel screen layer and copper foil layer three.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of copper foil tape of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, this structure being used for the copper foil tape of electromagnetic shielding is: be disposed with printing pet layer 1, ink layer 2, composite layer 3, nickel screen layer 4, copper foil layer 5, pressure-sensitive adhesive layer 6 and release film layer 7 from top to bottom.The electromagnetic shielding adhesive tape be made up of Copper Foil had both possessed excellent conductivity, had again good pliability, repeatedly repeatedly can bend and not rupture.Meanwhile, Copper Foil can isolating electromagnetic to the injury of human body, avoid extra voltage and electric current on the impact of self product function.But with regard to Copper Foil itself, its electric screen ability is better than its shielding ability, therefore in order to improve the shielding ability of copper foil tape further, the nickel element with excellent magnetic shield performance is introduced in this case, it is configured to honeycomb network structure, and this nickel screen is located between composite layer 3 and copper foil layer 5, and the thickness of nickel screen layer 4 is preferably set to 3 ~ 5 μm, if the thickness < of nickel screen layer 43 μm, then manufacturing cost raises; If the thickness G reatT.GreaT.GT of nickel screen layer 45 μm, then add the hardness of product, easily cause glue-line to ftracture and come off.
In copper foil layer 5, be provided with honeycomb groove near the one side of pressure-sensitive adhesive layer 6, this groove can increase the contact surface area of copper foil layer 5, makes its cohesive force with pressure-sensitive adhesive layer 6 more by force, thus ensure that the structural stability of product.
In addition in the present case, the thickness of printing pet layer 1 is preferably 4 ~ 6 μm, the thickness of ink layer 2 is preferably 1 ~ 2 μm, the thickness of composite layer 3 is preferably 5 ~ 15 μm, the thickness of copper foil layer 5 is preferably 5 ~ 10 μm, the thickness of pressure-sensitive adhesive layer 6 is preferably 10 ~ 20 μm, and the thickness of release film layer 7 is preferably 20 ~ 30 μm.The thickness of ink is thinner, and its production technology is more complicated, and in conjunction with the surface possessed needed for final products sub-luminosity, blackness and solvent resistance, the thickness of ink layer 2 should preferably control at 1 ~ 2 μm.If the thickness < of copper foil layer 55 μm, then can affect its electromagnetic shielding capability, if the thickness G reatT.GreaT.GT of copper foil layer 5 10 μm, then can increase the hardness of product, reduce the pliability of product, thus reduce its useful life.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
