Copper Foil is the high performance electromagnetic shielding material of a class, is used for the metallic shield adhesive tape preparing all kinds of simple function in prior art.But this kind of adhesive tape is used in the severe environment such as airtight, moist, and malaria can cause irreversible erosion and damage to the components and parts of electronic product.In addition, containing more photosensor in electronic product, certain requirement is had to the opacifying property of auxiliary and Total Product and photophobism.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the composite electromagnetic shielding adhesive tape providing a kind of thickness thin, lightweight, easy to use, it had both had excellent electro-magnetic screen function, good shading performance can be possessed again, also there is high humidity resistance simultaneously, 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, duplicating machine can be widely used in.
For achieving the above object, the utility model is achieved through the following technical solutions:
The moistureproof electromagnetic shielding adhesive tape of a kind of shading, is provided with the first ink layer, printing pet layer, the second ink layer, the first adhesive layer, aluminium foil layer, the second adhesive layer, copper foil layer, pressure-sensitive adhesive layer and release film layer from top to bottom successively.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described first ink layer and the second ink layer is 1 ~ 2 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described printing pet layer is 10 ~ 15 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described first adhesive layer and the second adhesive layer is 5 ~ 10 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described aluminium foil layer is 6 ~ 8 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described copper foil layer is 5 ~ 10 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, the thickness of described pressure-sensitive adhesive layer is 10 ~ 20 μm.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, described aluminium foil layer two sides is equipped with honeycomb groove.
Preferably, the moistureproof electromagnetic shielding adhesive tape of described shading, described copper foil layer two sides is equipped with honeycomb groove.
The beneficial effects of the utility model are: 1) screening effect of individual layer ink layer is undesirable, and degree of staining is uneven, adopt double-deck ink layer effectively can improve the screening effect of ink; 2) adopt printing level PET and ink to arrange in pairs or groups, ensure that the distribution consistency degree of ink; 3) adopt the Copper Foil with low surface oxidation characteristic, the electromagnetic shielding capability of adhesive tape can be improved; 4) not only can the electromagnetic shielding capability of effective improving product by arranging aluminium foil layer, it also has excellent shading and moisture-proof function simultaneously, has enriched the range of application of adhesive tape; 5) honeycomb groove is set at aluminium foil layer and copper foil layer two sides, effectively can increases contact surface area, improve the bonding force of Copper Foil and aluminium foil and glue-line, ensure the structural stability of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the moistureproof electromagnetic shielding adhesive tape of a kind of shading 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 sheets word to make those skilled in the art.
As shown in Figure 1, the structure of the moistureproof electromagnetic shielding adhesive tape of this shading is: be disposed with the first ink layer 1, printing pet layer 2, second ink layer 3, first adhesive layer 4, aluminium foil layer 5, second adhesive layer 6, copper foil layer 7, pressure-sensitive adhesive layer 8 and release film layer 9 from top to bottom.The electromagnetic shielding adhesive tape be made up of Copper Foil had both possessed excellent electroconductibility, had again good snappiness, 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.This case is in order to improve the electromagnetic shielding capability of adhesive tape further, and introduce the aluminium foil layer 5 with excellent electromagnetic shielding properties, it is arranged between the first adhesive layer 4 and the second adhesive layer 6.Aluminium foil not only has electro-magnetic screen function, and it also has the function such as shading, protection against the tide, can improve the screening effect of adhesive tape, ensures the photosensitive semiconductor steady running in electronic product, protects electronic devices and components from moisture attack simultaneously.
In the present case, only not good at the screening effect of PET coated on one side one deck ink of printing level, the coating thickness of ink is thin, its surperficial sub-luminosity and dispersing uniformity not good, after the PET two sides in printing level is respectively coated with one deck ink, surperficial sub-luminosity and coating uniformity are all obviously promoted.Being equipped with honeycomb groove on the two sides of aluminium foil layer 5 and copper foil layer 7, its objective is to increase contact surface area, improve the bonding force of Copper Foil and aluminium foil and glue-line, ensure the structural stability of product.
The thickness of the first ink layer 1 and the second ink layer 3 is all preferably 1 ~ 2 μm, the thickness of printing pet layer 2 is preferably 10 ~ 15 μm, the thickness of the first adhesive layer 4 and the second adhesive layer 6 is all preferably 5 ~ 10 μm, the thickness of aluminium foil layer 5 is 6 ~ 8 μm, the thickness of copper foil layer 7 is 5 ~ 10 μm, the thickness of pressure-sensitive adhesive layer 8 is 10 ~ 20 μm, and the thickness of release film layer 9 is preferably 20 ~ 30 μm.Wherein, if the thickness of aluminium foil layer 5 is less than 6 μm, then can affects its electro-magnetic screen function and shading, moisture-proof function, and cause reduce its work-ing life; If the thickness of aluminium foil layer 5 is greater than 8 μm, then can increase the integral hardness of adhesive tape, reduce the snappiness of adhesive tape, thus make adhesive tape cracky in use.If the thickness < of copper foil layer 75 μm, then affect its electromagnetic shielding capability and work-ing life; If the thickness G reatT.GreaT.GT of copper foil layer 7 10 μm, then can increase hardness and the production cost of product.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification sheets 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.
