Abstract

The invention relates to a thermal transfer printing conductive film for a radio-frequency identification tag antenna. The conductive film comprises a base material, a release layer which is coated on the surface of the base material, a conductive metal layer which is evaporated on the surface of the release layer and a conductive adhesive layer which is coated on the surface of the conductive metal layer, wherein the release layer is formed by solidifying coating liquid consisting of the following components in parts by weight: 8 to 16 parts of ammonium-base modified acrylic ester, 10 to 15 percent of inorganic modified acrylic ester resin, 20 to 30 parts of dipentaerythritol hexaacrylate, 1 to 3 parts of photoinitiator, 3 to 7.5 parts of gas-phase silicon dioxide, 0.6 to 2 parts of dispersing agent, 0.4 to 1.5 parts of anti-adhesion agent and 30 to 57 parts of solvent. The radio-frequency identification tag antenna produced by adopting the thermal transfer printing conductive film has the advantages of high fineness and stability in conductivity.

Description

technical field [0001] The invention relates to a conductive film, in particular to a heat-transfer conductive film used for radio frequency identification tag antennas. Background technique [0002] At present, the manufacturing methods of RFID tag antennas include chemical etching / stamping antennas, printing antennas, wire-wound antennas, etc. Common RFID antenna substrates include paper base and film base. Internationally, etching / stamping antennas are currently the mainstay. With the rapid development and application of radio frequency identification cards and the development of conductive inks, the application of printed antennas is also gradually increasing. The traditional etching / stamping manufacturing method has the disadvantages of complex process and low efficiency, especially for paper and other materials, which need to be processed after etching. However, the conductive stability of conductive ink printing is greatly affected by the conductivity of the ink, and...
