Example Embodiment

[0029] Example 1: Weigh the epoxy resin, epoxy toughness modifier, adhesion promoter, rheology control agent according to the mass given in Table 2 and mix them. The mixing method is mechanical stirring, the stirring speed is 1000 rpm, and the time is 10 minutes. Then, the weighed mixed filler of silver nanowire and silver nanoparticle, filler surface modifier, and diluent are sequentially added to the mixture under stirring. After the addition, stirring was continued for 10 minutes. After mixing uniformly, add curing agent and curing accelerator to the mixture. After mechanical stirring for 5 minutes, transfer the mixture to a high-speed shear mixer for mixing. The mixing speed is 2000 rpm and the time is 30 seconds. Repeat the mixing process in the high-speed shear mixer 3 times to obtain a uniformly mixed gel that is the conductive ink.

Abstract

The invention relates to a conductive printing ink composite for printing of wireless radio frequency identification devices (RFID), which comprises the following components in percentage by weight: 2%-10% of at least one type of epoxy resin, 5%-10% of epoxy resin toughness modifier, 30%-50% of reactive diluent, 2%-4% of curing agent, 1%-1.5% of curing accelerator, 30%-50% of conductive filler, 10%-30% of organic solvent, and 0-1.5% of flowing additive, adhesion promoter, rheological control agent and filler surface modifier. The conductive printing ink for the printing of the RFID has the advantages of high conductivity, high adhesion strength, stable electrical property and the like, and has good printing property on high-energy surfaces of metal, ceramics, glass and polymers.

Description

technical field [0001] The invention relates to conductive ink, in particular to a conductive ink composition for radio frequency identification system printing. Background technique [0002] With the rise of the Internet of Things industry, smart labels have gradually entered people's field of vision. Smart tags are also called electronic tags. It is a radio frequency identification system (RFID). It is a kind of non-contact RFID through radio waves. It is a high-tech product in the field of labels. Now it has played an important role in product packaging and anti-counterfeiting. There is a tendency to gradually replace traditional product labels and barcodes. RFID tags are radio frequency circuits composed of multiple layers such as chips and antennas. Utilizing the characteristics of different materials, they play different roles to complete the function of electronic tags in radio frequency identification of products. Among them, the antenna layer is the main function...
