Description
Technical field
The utility model relates to a kind of composite, particularly relates to a kind of anti-scratch copper foil tape for electromagnetic shielding.
Background technology
Along with the arrival of digital age, the electronic products such as such as notebook computer, palm PC, mobile phone, duplicator 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 is exposed to powerful electromagnetic after the match for a long time, 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 external diffusion; 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 Copper Foil itself is very soft, is easily scraped off or is poked by hard object, and once Copper Foil sustains damage, easily there is potential safety hazard, causes its effectiveness to be had a greatly reduced quality, even can the unnecessary accident such as fire hazard time serious.
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, good anti-scratch performance can be possessed 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, duplicator can be widely used in.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of anti-scratch copper foil tape, be provided with printing pet layer, ink layer, the first adhesive layer, scratch-resistant layer, the second adhesive layer, copper foil layer, pressure-sensitive adhesive layer and release film layer from top to bottom successively, wherein, described copper foil layer two sides is equipped with honeycomb groove.
Preferably, described anti-scratch copper foil tape, the thickness of described printing pet layer is 4 ~ 6 μm.
Preferably, described anti-scratch copper foil tape, the thickness of described ink layer is 1 ~ 2 μm.
Preferably, described anti-scratch copper foil tape, the thickness of described first adhesive layer and the second adhesive layer is 5 ~ 10 μm.
Preferably, described anti-scratch copper foil tape, the thickness of described scratch-resistant layer is 3 ~ 5 μm.
Preferably, described anti-scratch copper foil tape, the thickness of described copper foil layer is 10 ~ 15 μm.
Preferably, described anti-scratch 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) adopt the Copper Foil with low surface oxidation characteristic, and on its two sides, honeycomb groove is set to increase contact surface area, on the basis ensureing product effectiveness, improve the adhesive force of Copper Foil and glue-line further, ensure the structural stability of product; 4) by setting up scratch-resistant layer, improve the scratch resistant ability of copper foil tape, while its capability of electromagnetic shielding of guarantee, the service life of this copper foil tape can be extended again.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-scratch copper foil tape of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, this structure being used for the anti-scratch copper foil tape of electromagnetic shielding is: be disposed with printing pet layer 1, ink layer 2, first adhesive layer 3, scratch-resistant layer 4, second adhesive layer 5, copper foil layer 6, pressure-sensitive adhesive layer 7 and release film layer 8 from top to bottom.The electromagnetic shielding adhesive tape be made up of Copper Foil had both possessed excellent electric 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.
Be equipped with honeycomb groove on copper foil layer 6 two sides, this groove can increase the contact surface area of copper foil layer 6, makes it stronger with the cohesive force of the second adhesive layer 5 and pressure-sensitive adhesive layer 7 respectively, 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 the first adhesive layer 3 and the second adhesive layer 5 is preferably 5 ~ 10 μm, scratch-resistant layer 4 is preferably fluorine resin, and its thickness is preferably 3 ~ 5 μm, and the thickness of copper foil layer 6 is preferably 10 ~ 15 μm, the thickness of pressure-sensitive adhesive layer 7 is preferably 10 ~ 20 μm, and the thickness of release film layer 8 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 6 10 μm, then offering honeycomb groove on its two sides easily causes it to break, if the thickness G reatT.GreaT.GT of copper foil layer 6 15 μm, then can increase the hardness of product, reduce the pliability of product, thus reduce its service life.Scratch-resistant layer 4 is fluorine resin; its hardness > 3H; run into shock or sharp object thorn draw time can available protecting copper foil tape from breakage; stop the potential safety hazard that electrostatic causes; if the thickness < of scratch-resistant layer 43 μm, then affect its anti-scratch performance, if the thickness G reatT.GreaT.GT of scratch-resistant layer 45 μm; then cause product hardness to increase, draw high production cost simultaneously.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment 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.
