Novel formula for RFID electronic label surface film with anti-counterfeiting function

Abstract

The invention discloses a novel formula for an RFID electronic label surface film with an anti-counterfeiting function. The formula for the RFID electronic label surface film with a temperature change fluorescent anti-counterfeiting function is composed of four parts 20% of a petroleum resin, 5% of a paraffin wax, 6% of a pigment, 33% of methyl stearate, 5% of methyl hexadecanoate, 9% of 2,6-di-tert-butyl-p-cresol, 8% of toluene, 3% of dimethylbenzene and 2% of phosphor powder. A silica gel compound has the temperature change fluorescent function by grinding the above formula and adding 300 g of transparent silica gel in 100 g of the formula grinded material. When a temperature reaches 45 DEG C, the silica gel material appears red and has the fluorescent function; and when the temperature does not reach 45 DEG C, the silica gel material appears transparent and does not have the fluorescent function. At the same time, the emission frequency and the signal accept intensity of the RFID electronic labels can not be influenced by covering the silica gel material on the RFID electronic label chips to form the surface film. The RFID electronic label surface film with the temperature change fluorescent anti-counterfeiting function has the anti-counterfeiting function and can meet the requirements of different level identifications.

Description

technical field [0001] The invention belongs to the field of chemical industry. Background technique [0002] The packaging surface film of the RFID electronic tag on the existing market is basically made of plastic (PVC) and general silica gel or paper. Can not play anti-counterfeiting function and personalized design. Some brands of RFID electronic tags have the problem of being counterfeited. Contents of the invention [0003] In order to overcome the problem that the encapsulation film of RFID electronic tags in the market cannot provide anti-counterfeiting function and personalized design, and some brand RFID electronic tags have the problem of being counterfeited, we have provided a temperature-changing fluorescent anti-counterfeiting function after research. The formula of the RFID electronic tag film, the film will not affect the transmitting frequency and signal receiving strength of the RFID electronic tag. [0004] The formula has high technical content and i...
