6) Compared with RFID products in other frequency bands, the data transmission rate of this frequency band is relatively slow
7) The price of the sensor is high
3) Radio waves in the ultra-high frequency band cannot pass through many materials, especially suspended particles such as water, dust, and fog
5) This frequency band has a good reading distance, but it is difficult to define the reading area
In China, although it has been reported that the longitudi

Example Embodiment

[0035] Example 1

[0036] Preparation of functional slice A: Use high-quality shell powder (commercially available) with an average particle size of less than 6μm, using titanate coupling agent (brand NDZ-201, commercially available), silane coupling agent (brand KH550, commercially available) , Surfactant (fatty acid glyceride ， Commercially available) for processing, using DMT method to synthesize functional slices A with a mass percentage of 0.1-13.5% of shell micropowder under the conditions of adding polyphosphoric acid (PPA for short). Functional polyester chip A satisfies the performance indicators including: moisture 0.62dL / g, diethylene glycol ≤1.4%, and the mass percentage of shell powder 0.1~13.5%.

[0038] Preparation of functional slice B: Put nano-montmorillonite (commercially available) into a high-speed mixer, then slowly add solvent-treated silane coupling agent (brand KH550, commercially available), and stir at high speed for 20 minutes to obtain modified nano-montmorillonite Desoil, use DMT method or PTA method to synthesize functional polyester chip B with a mass percentage of 0.5-32.6% of nano-montmorillonite. Functional slice B satisfies the performance indicators including: water content 0.62dL / g, diethylene glycol ≤1.4%, and nano-montmorillonite mass percentage 0.5~32.6%.

[0039] Example 3

[0040] Prepare recycled particles of waste polyester material. After pulverizing and heating the recycled waste polyester material without impurities, it is dehydrated, dried, removed low molecular weight, filtered, melted and extruded in a vacuum exhaust type regranulation extruder. Granulate and then dry both. The performance indicators that the recycled particles of waste polyester materials meet include: moisture content 0.59dL / g, and diethylene glycol ≤ 1.5%.

[0041] Preparation of ordinary polyester chips: the large-scale industrialized PTA method is used to synthesize ordinary polyester chips, namely basic chips, using PTA and EG.

[0042] Preparation of IPA chips: The production method is the same as that of ordinary polyester chips. IPA chips can be obtained by only replacing PTA with IPA. The mass percentage of IPA in polyester chips containing IPA is 0.2-7.8%.

Abstract

The invention discloses a polyester film for an electronic tag and a preparation method thereof. The preparation raw materials of the polyester film for the electronic tag comprises the following components in percentage by weight: 0.1-35.6 percent of functional chip A, 0.1-42.2 percent of functional chip B, 20-68 percent of recycled particle of waste polyester material, 40-90 percent of common polyester chip, 1-12 percent of polyester chip containing IPA (isopropyl alcohol), and 5-92 percent of silicon chip, wherein the mass percentage content of shell micro powder in the functional chip A is 0.1-13.5 percent; the mass percentage content of nano-montmorillonite in the functional chip B is 0.5-32.6 percent; the mass percentage content of the IPA in the polyester chip containing the IPA is0.2-7.8 percent; and the mass percentage content of silicon oxide in the silicon chip is 200-18900PPM (parts per million). Compared with the polyester film for the electronic tag in the prior art, the polyester film for the electronic tag disclosed by the invention has the outstanding advantages that: the polyester film for the electronic tag has longitudinal thermal shrinkage being within 0-1 percent at the high temperature of 180 DEG C, dielectric constant being within 1-3 under a test condition of 1 GHz, and dielectric loss tangent value being 0.2 percent to 0.8 percent; meets the use requirement of the electronic tag; has good practical applicability; and can make better economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of new polymer materials for electronic products, and in particular relates to a polyester film for electronic labels and a preparation method thereof. Background technique [0002] Radio Frequency Identification (RFID), commonly known as electronic tags, is a non-contact automatic identification technology, which automatically identifies target objects and obtains relevant data through radio frequency signals, used to control, detect and track objects, and can work in various It can identify high-speed moving objects and identify multiple tags at the same time. The identification work does not require manual intervention, and the operation is fast and convenient. RFID is a simple wireless system, including an interrogator (or reader) and many transponders (or tags), its basic structure is composed of tags, readers and antennas; tags (Tag) are composed of coupling elements and chips , each tag has a unique ...
