Problems solved by technology

[0006] In addition, the radio frequency electronic tags based on traditional polyester materials are difficult to be destroyed and are easy to be transferred and reused. Criminals can completely peel off the radio frequency identification electronic tags on genuine goods through certain physical and chemical means without destroying their physical properties. structure, the label can still be read, and if it is pasted on the counterfeit product, it will be difficult to distinguish it from the real product, and it will lose its significance as anti-counterfeiting and logistics management

Embodiment 1

[0049] Using 80 grams of coated paper as the supporting layer material, use a coating machine to coat the functional polymer material on both sides of the supporting substrate with a coating thickness of 6 microns; the functional polymer material is made of water-based polyurethane resin material;

[0050] After drying through an infrared drying tunnel, use a 400-mesh screen-printed conductive silver paste on the surface of the functional polymer coating to form an RFID antenna after drying, and pass the RFID chip through a thermosetting conductive adhesive (XH9850 from NAMICS, Japan). ) for bonding and curing by hot pressing, the hot pressing temperature is 160°C, and the curing time is 8 seconds; use the RFID reader matching the chip to input data and obtain the product, its structure is as follows figure 1 shown.

Embodiment 2

[0052] With 40 grams of offset printing base paper as the supporting layer material, using a coating machine, the functional polymer material is coated on both sides of the supporting substrate, and the coating thickness is 8 microns; the functional polymer material is selected from a mixture of polyurethane resin and acrylic resin ( 2:1, weight ratio);

[0053] And dry through an infrared drying tunnel; compound the 16-micron thick aluminum foil with the above-mentioned functional polymer coating through an adhesive, and then print the antenna pattern on the aluminum foil by gravure printing, and then undergo acid or alkali etching and deinking treatment Finally, the etching antenna is formed; then the RFID chip is bonded with a thermosetting conductive adhesive, and cured by hot pressing. The hot pressing temperature is 160 ° C, and the curing time is 10 seconds; the RFID reader that matches the chip is used for data recording. Enter to get the product. Its structure is as ...

Embodiment 3

[0055] Using 80 grams of double-adhesive paper as the supporting layer material, use a coating machine to coat the functional polymer material on both sides of the supporting substrate with a coating thickness of 8 microns; the functional polymer material is made of water-based epoxy resin and acrylic resin. Mixture; (1:3, weight ratio);

[0056] Drying in an infrared drying tunnel; use 500-mesh screen-printed conductive silver paste as a seed layer on the functional polymer coating, and then deposit copper on the seed layer by chemical deposition to form an electroless copper-plated antenna; then The RFID chip is bonded with a thermosetting conductive adhesive (6998 from UNINWELL Company), and cured by hot pressing. The hot pressing temperature is 140°C, and the curing time is 10 seconds; use an RFID reader that matches the chip for data recording. Enter to get the product. Its structure is as figure 1 shown.

Abstract

The invention discloses a radio frequency identification electronic tag and a method for manufacturing the same. The radio frequency identification electronic tag comprises a support layer, functional polymer coatings, antennas and a chip, the chip is adhered with the antennas via conductive thermosetting resin, the functional polymer coatings are coated on two sides of the support layer, the antennas are adhered on the functional polymer coatings, and the support layer is made of paper materials. The support layer is made of the paper materials, the paper materials are free of redound effects, high in tag conducting rate and the like, accordingly, the conducting rate of the high-frequency radio frequency identification electronic tag can be obviously increased, and the production cost of the radio frequency identification electronic tag is reduced. Besides, the radio frequency identification electronic tag has the advantages that the radio frequency identification electronic tag is easy to damage, accordingly is transfer-preventive, and the like. The radio frequency identification electronic tag and the method are applicable to the field of anti-counterfeiting traceability of goods, and problems in the prior art are solved.

Description

technical field [0001] The invention relates to a radio frequency identification electronic tag and a preparation method thereof. Background technique [0002] Radio frequency identification (RFID) technology automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual interference and can work in various environments. It can identify multiple tags at the same time, and the operation is fast and convenient. After 2004, RFID technology has developed vigorously, and has wide application potential in the fields of warehousing and logistics, product anti-counterfeiting, product circulation, and product maintenance and tracking. In the application of product anti-counterfeiting, RFID is called a new generation of "electronic patron saint" because of its safety, efficiency, speed, large storage capacity, and free change of stored information. [0003] At the same time, because the UID code of...
