Abstract

The invention relates to a modification method for jet printing base material pet for RFID label antenna based on particle-free type conductive ink. The method includes the following steps that a pet film is washed with deionized water, then subjected to extraction for 24 hours in a mixed solution of ethyl alcohol, ethyl acetate and acetone, then taken out and then dried in a vacuum oven at the temperature of 90 DEG C for standby application, and the treated pet film is obtained; and the treated pet film is preheated to the temperature of 30-40 DEG C and is subjected to corona treatment under the current intensity of 2-10 A on a corona treatment machine at the speed of 8-15 m / min under the stable power of 10-18 kw, and the modified pet film is obtained. According to the modification method, surface modification is conducted on printing base material polyethylene terephthalate through corona treatment, and a base material polyester film which is suitable for particle-free type conductive ink jet printing and has excellent printability is obtained; and the quality of the printed label antenna is improved, it is tested that the absorptivity of the pet film treated through corona to printing ink is high, the electrical conductivity of the printed label antenna is improved greatly, and the readability is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of electronic tags, in particular to a method for modifying a base material PET for inkjet printing of RFID tag antennas based on particle-free conductive ink. Background technique [0002] With the rapid development of the Internet, radio frequency identification technology (RFID) has quickly become a huge potential market, and it will become a trend in the future to use printed electronic technology to print RFID tag antennas. Inkjet printing is to spray ink from fine nozzles to the substrate at a certain speed. It has the advantages of no printing plate, no contact and accurate forming. Inkjet printing has become the first choice for printing label antennas due to its unique advantages. printing method. Inkjet printing reproduces an image through ink droplets, which are the basic unit of an image. The image quality of inkjet printing depends on the interaction between the ink and the substrate. In gener...
