Abstract

The invention discloses water-based ink for a radio frequency identification antenna and a preparation method thereof. The preparation method comprises the following steps of: mixing a water-based polymer resin, conductive carbon black, water, ethanol, an antistatic agent and a carbon black dispersing agent according to a ratio and uniformly dispersing; grinding to make the fineness meet the requirement; and filtering, and uniformly dispersing with a certain amount of triethanolamine and antifoaming agent so as to prepare the water-based ink for the radio frequency identification antenna. Theink has the advantages of quick curing for an ink layer and high adhesion, and can be directly diluted with water in the using process; and printing equipment can be directly cleaned with water afterfinishing the printing. The ink is applied to various printing modes, and has the advantages of safety, environmental protection, simple preparation method, wide source of materials and low production cost.

Description

technical field [0001] The invention relates to a water-based ink for a radio frequency identification (Radio Frequency Identification, abbreviated as RFID) antenna, which is processed with water-based polymer resin as a connecting material, conductive carbon ink as a conductive material, and water, ethanol and a defoamer. The preparation method belongs to the technical field of printing. Background technique [0002] At present, microelectronics technology is infiltrating into various fields, and conductive printing technology emerges as a high-tech. This product is specially used for printing ink on the transmitting antenna of RFID components, and is made by combining the printed transmitting antenna and RFID board; it has the advantages of simple structure, beautiful appearance, and long durability. Ink printed circuit has simple process, high efficiency, and saves metal copper. It is an effective way to reduce the cost of microelectronics products. Others are used in to...
