Embodiment

[0052] Conductive ink comprises conductive material, solvent, calcium carbonate filler and additive, and the content of each component of conductive ink is as table 1:

[0053] The content of each component of the conductive ink of table 1 (here all are mass percentages)

[0054]

[0055]

[0056] After the above-mentioned components are mixed according to the above-mentioned ratio, the conductive ink is uniformly dispersed to form a conductive ink, which is evenly coated on the top of the PET substrate by 100T screen printing method, and heated and cured at 120°C to obtain a conductive pattern with a thickness of 20 μm 120. Cover the surface of the conductive pattern 120 with a PE protective film 130, and heat emboss for 10s at a temperature of 45°C and a pressure of 0.5MPa to obtain figure 1 RFID tags shown.

[0057] The obtained RFID tags were subjected to environmental acidification and weathering simulation tests. The specific method was: the RFID tags prepared in...

Abstract

The invention provides electrically conductive ink, an electronic tag, a preparation method of the electronic tag and a radio frequency identification system, and belongs to the technical field of radio frequency identification. The electrically conductive ink is used for preparing the electronic tag; and the electrically conductive ink is prepared from an electrically conductive material, a calcium carbonate filling material and a solvent. The preparation method of the electronic tag comprises the following steps of coating the electrically conductive ink on one surface of a substrate to forman electrically conductive pattern, and covering the surface of the electrically conductive pattern with a protective film. The radio frequency identification system comprises an antenna, a reader-writer and the electronic tag, wherein the antenna is used for receiving a signal transmitted by the electronic tag; and the reader-writer is electrically connected with the antenna and is further usedfor reading the signal to obtain information. The intelligent identification system uses the electronic tag prepared from the electrically conductive ink, can be used for solving the technical problemthat the corrosiveness of a rock cannot be monitored in the prior art, and can be used for effectively monitoring the corrosion condition of calcium carbonate in an environment.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a conductive ink, an electronic label, a preparation method thereof and a radio frequency identification system. Background technique [0002] When marine cultural relics, buildings in the soil and other cultural relics are corroded, holes will be formed. In order to repair the cultural relics or buildings, the holes will be filled with paint, and the paint will corrode after a certain period of time. [0003] In the prior art, the corrosion of the paint can only be monitored manually, and intelligent monitoring cannot be performed. Contents of the invention [0004] The object of the present invention is to provide a conductive ink, an electronic label, its preparation method and a radio frequency identification system, which can solve the technical problem that rock corrosion cannot be monitored in the prior art, and can effectively monitor the corrosio...
