A kind of transparent invisible RFID tag material and preparation method

Abstract

The invention discloses a transparent invisible RFID label material and a preparation method thereof. The transparent invisible RFID label material is a matrix layer, a conductive layer and an adhesive layer in sequence from top to bottom, and the light transmittance of the matrix layer is >95%. The thickness of the conductive layer is 10-50 μm, the surface resistivity of the conductive layer is <30Ω, the transparency is >90%, and the thickness of the adhesive layer is 1-10 μm. The preparation method of the transparent invisible RFID label is to lay the substrate layer flatly on the coating platform first, and coat the nano-silver wire conductive silver paste on the substrate layer through a coating machine, and the nano-silver wire conductive silver paste is cured to form a conductive layer, which is conductive Layers are screen printed or mechanically embossed to form conductive patterns. Finally, the adhesive is further coated on the conductive layer, and the transparent invisible RFID label material is obtained after curing. The invention provides a transparent invisible RFID label material with high transparency, good flexibility, extremely low surface resistance, good bending resistance and good anti-theft and anti-counterfeiting functions and a preparation method thereof.

Description

technical field

[0001] The invention relates to the field of RFID technology, in particular to a transparent invisible RFID label material and a preparation method. Background technique

[0002] Conventional RFID tags have the function of RFID management and identification, but because the RFID tags currently on the market are usually made of copper foil and aluminum foil, they are opaque, and criminals can use many methods to remove them, such as tearing off a corner of the label, using In the form of hot air blowing or other methods, the label is completely removed and transferred to other items, thereby losing the authenticity and uniqueness of the product, and the conventional RFID label has weak bending resistance and is easily damaged.

[0003] Therefore, it is an urgent technical problem to develop an RFID label material that is transparent, flexible, extremely low surface resistance, strong in bending resistance, and has good anti-theft and anti-counterfeiting functi...
