The problem of limit.Meanwhile etching method needs strong acid solution to corrode unprotected metal layer and strong base solution removal protective layer, therefore
It need to be using macromolecule membrane as antenna substrate.However, the toughness of polymer base material and metal antenna is stronger, it is difficult to be torn damage,
Therefore it needs metal antenna being transferred to paper base material by polymer base material and increases die cut, but this method significantly increases
Preparation cost, and the effect is unsatisfactory for anti-transfer.When these electronic tag tear-offs, by being die cut or adhesive is influenced, some
Can whole uncover, some only destroy the part of label, still can normal use, anti-fake purpose can not be played.Print process
It is common RFID antenna preparation method, directly antenna can be printed on paper base material.Common RFID mode of printing includes
Intaglio printing, orifice plate printing and ink jet printing etc..Its aperture plate mode of printing is divided into silk-screen printing and openworking template printing etc. again.
But mainly for the preparation of silver-colored antenna and copper antenna, it is low achievable that this is mainly due to the fusing points of nano silver and Nanometer Copper for printing process

The size of graphene antenna is length × wide=20mm × 20mm, and with a thickness of 20 μm, shape is as shown in Figure 5.
The ground paper layer of the RFID tag of the present embodiment uses leaching membrane paper, and adhesive uses epoxide-resin glue, and conducting resinl uses
Anisotropy elargol, paper base material use extrusion coating paper.
The size of RFID tag is length × wide=30mm × 30mm.
The RFID tag of the present embodiment can be prepared by the following method：
Step 1：Graphene sheet layer, vinyl chloride-vinyl acetate resin are uniformly mixed with solvent, obtain graphene ink；
Step 2：Using openworking template print process, by graphene ink by designed in roll-to-roll printing equipment
Graphic printing on paper base material surface, and be heated to 120 DEG C electric heating and infrared heating associated with dry in drying cabin and formed
Graphene antenna is cut into the coiled material that width is 20mm using cutting machine by graphene antenna；
Step 3：Using chip encapsulating device on the designated position point of graphene antenna coiled material anisotropy elargol, so
Afterwards by RFID chip package in the designated position；
Step 4：It is using compounding machine that the RFID antenna and ground paper layer that have encapsulated chip is compound by epoxide-resin glue；
Step 5：Using die-cutting machine will be completed step 4 label coiled material carry out shape by die-cutting, obtain RFID tag at
Product.
