preparation example Construction

[0044] The preparation method of the low-voltage heating ink specifically comprises the following steps:

[0045] (1) Weigh the components of the low-voltage heating ink in parts by mass, put the water-based acrylic resin, rosin resin, pH regulator and deionized water in a stirring tank and stir for 5 to 10 minutes. After mixing evenly, add Carbon black, graphite, carbon nanotube dispersion and xanthan gum, stir evenly, finally add dispersant and defoamer, stir evenly to form primary heating ink;

[0046] (2) After mixing the primary heating ink and ball milling beads according to the mass ratio of 3:1, put it in an electric mixer and stir for 1 to 3 hours, then take it out and filter it, and finally put the primary heating ink in a sand mill and grind it until the particle size is below 5 μm , Obtain low voltage heating ink.

[0047] In the preparation process of the low-voltage heating ink, xanthan gum can form a stable three-dimensional network structure with conductive fi...

Abstract

The invention belongs to the technical field of anti-counterfeit labels, and particularly relates to an anti-counterfeit label which at least comprises a substrate layer, the substrate layer at leastcomprises a loop formed by a label part, a wire part and a USB interface, and the label part and the wire part are both made of low-voltage heating ink; a middle layer and a covering layer for displaying patterns are sequentially arranged above the substrate layer, the middle layer is made of white ink, and the covering layer is made of temperature change ink. The charging power supply or the mobile power supply can be directly connected with the USB interface arranged on the anti-counterfeit label to supply power to the anti-counterfeit label, so that the anti-counterfeit label is convenientto use and is not limited by places; the low-voltage heating ink can show a relatively good heating effect within a relatively short time under a relatively low working voltage, so that the temperature change ink for displaying patterns in the covering layer changes color, anti-counterfeiting patterns with different colors are generated, and the anti-counterfeiting purpose is achieved; in addition, the color change effect of the temperature change ink can be changed by changing the charging voltage and the thickness of the low-voltage heating ink layer.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeit labels, in particular to an anti-counterfeit label. Background technique [0002] The anti-counterfeiting label is a mark that can be pasted, printed, and transferred on the surface of the object, and has an anti-counterfeiting effect. The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the main structure of anti-counterfeiting labels. Anti-counterfeiting is a preventive measure against counterfeiting or copying activities for the purpose of deception without the permission of the owner. At present, the diversity of anti-counterfeiting technologies has produced watermark anti-counterfeiting, digital coding anti-counterfeiting, barcode anti-counterfeiting, two-dimensional code anti-counterfeiting, etc., but these labels cannot directly produce color changes, which give people a visual impact. [0003] Temperature-changing ink is a mature existing ...
