Description
Technical field
This utility model belongs to electromangnetic spectrum field, is specifically related to a kind of electromagnetic masking printed label.
Background technology
Printed label series products is used as electromagnetic shielded product in the fields such as communication, electronics, household electrical appliances, ship, mainly covers when high-frequency transmission or the interference of isolating electromagnetic.
Existing printed label series products, after usually using Merlon (PC) or other plastic sheets to directly print, sticking double faced adhesive tape at the printed label back side can complete.But, equipment is typically provided at button, LED or diode lights, therefore has key hole, LED hole or diode lamp hole on printed label accordingly, electromagnetic wave at this some holes, can be leaked out.When printed label of the prior art is pasted in casing by double faced adhesive tape, can not prevent electromagnetic wave from revealing at printed label, therefore, printed label of the prior art can not play firm electromagnetic interference (EMI) and the effect of electromagnetic compatibility (EMC) problem because not having electro-magnetic screen layer.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electromagnetic masking printed label, the leakage of electromagnetic radiation can be effectively prevented, electromagnetic interference (EMI) and the problem of electromagnetic compatibility (EMC) of electronic product can be effectively solved.
For reaching this purpose, this utility model by the following technical solutions:
Electromagnetic masking printed label, including printed label body layer, Graphene electro-magnetic screen layer and conductive adhesive layer, described Graphene electro-magnetic screen layer is arranged between described printed label body layer and described conductive adhesive layer.
Wherein, described Graphene electro-magnetic screen layer comprises at least two layer graphenes.
Graphene is the two dimensional crystal of the only one layer of atomic thickness being stripped out from graphite material, being made up of carbon atom.Graphene is the thinnest material, is also the most tough material, more taller than best steel 200 times of fracture strength.It has again good elasticity simultaneously, and stretch range can reach the 20% of own dimensions.It is the material that current nature is the thinnest, intensity is the highest, it addition, Graphene is almost fully transparent, only absorbs the light of 2.3%.On the other hand, it is the finest and close, even the gas atom of minimum (helium atom) also cannot penetrate, these features make it be highly suitable as the raw material of transparent electron product, Graphene is the thinnest, the novel nano-material that maximum intensity, electrical and thermal conductivity performance are the strongest having now been found that, it has good application prospect in terms of electromagnetic shielding and absorbing material.
Wherein, the thickness of described Graphene electro-magnetic screen layer is 1～10nm, such as 1nm, 2nm, 3nm, 4nm, 5nm, 6nm, 7nm, 8nm, 9nm, 10nm.
Wherein, the thickness of described Graphene electro-magnetic screen layer is 5nm.
Wherein, described printed label body layer is Polycarbonate Layer.
Wherein, described conductive adhesive layer is provided with hollow hole.
Wherein, the thickness of described conductive adhesive layer is 0.01～0.05mm, such as 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm.
Wherein, it is provided with glue-line between described printed label body layer and described Graphene electro-magnetic screen layer.
Wherein, the thickness of described glue-line is 0.01～0.05mm, such as 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm.
Compared with prior art, the beneficial effects of the utility model are: electromagnetic masking printed label of the present utility model, including printed label body layer, Graphene electro-magnetic screen layer and conductive adhesive layer, described Graphene electro-magnetic screen layer is arranged between described printed label body layer and described conductive adhesive layer；Electromagnetic masking printed label of the present utility model, use Graphene as electro-magnetic screen layer, can effectively prevent the leakage of electromagnetic radiation, play the effect of electromagnetic shielding, thus can effectively solve electromagnetic interference (EMI) and the problem of electromagnetic compatibility (EMC) of electronic product.
Accompanying drawing explanation
Fig. 1 is the structural representation of electromagnetic masking printed label of the present utility model.
Reference is as follows:
1-printed label body layer；2-Graphene electro-magnetic screen layer；3-conductive adhesive layer.
Detailed description of the invention
Below in conjunction with Fig. 1, and further illustrate the technical solution of the utility model by detailed description of the invention.
As it is shown in figure 1, electromagnetic masking printed label of the present utility model, including printed label body layer 1, Graphene electro-magnetic screen layer 2 and conductive adhesive layer 3, described Graphene electro-magnetic screen layer 2 is arranged between described printed label body layer 1 and described conductive adhesive layer 3；Graphene electro-magnetic screen layer 2 is prepared from through being in harmonious proportion, depositing by Graphene, plays the effect of electromagnetic shielding, and the transparency of Graphene electro-magnetic screen layer is good, conductivity is high, toughness is strong.Further, the thickness of Graphene electro-magnetic screen layer 2 is 1～10nm；Further, the thickness of Graphene electro-magnetic screen layer 2 is 5nm, and Graphene electro-magnetic screen layer 2 thickness is thin, transparency good, can play the effect of good electromagnetic shielding.
As preferred version of the present utility model, the printed label body layer that printed label body layer 1 is made for makrolon material, it is also possible to make for other materials such as plastic sheetings.Preferably, printed label body layer 1 comprises ink print away from the one side of Graphene electro-magnetic screen layer 2.
As preferred version of the present utility model, Graphene electro-magnetic screen layer 2 is connected by conductive adhesive layer 3 with equipment shell, and conductive adhesive layer 3 can be electrically conducting transparent glue-line, but in being actually needed, and in conductive adhesive layer 3, Chang Yin with the addition of conductive materials and is opaque.Preferably, when conductive adhesive layer 3 is opaque, conductive adhesive layer 3 is provided with hollow hole, it can be 1,2,3,4, or it is designed as more according to actual needs, hollow hole is used as key hole, LED hole, diode lamp hole or the hole of other purposes, and the use making label is more convenient, purposes is more extensive.It is highly preferred that the thickness of conductive adhesive layer 3 is 0.01～0.05mm.
