[0025]

[0026] 10 kg of anti-counterfeiting toner is produced in each batch, according to the proportion of the above formula components, and made according to the following steps:

[0027] (1) Evenly mix polymer resin, polypropylene wax, blue pigment, charge regulator and anti-counterfeiting material in a mixer to make a mixture;

[0028] (2) Then put the above mixture into the extruder, and slowly heat it, press the above mixture into tablets at a temperature of 100-155°C, and grind it into powder with a coarse powder machine after cooling:

[0029] (3) After that, use a fine powder machine to further pulverize the above-mentioned pulverized powder, and carry out classification, separation, and collection to obtain a primary product with a particle size of 5--12 μm:

[0030] (4) Add silicon dioxide, dimethyldichlorosilane and hexamethyldisilazane, and mix with a mixer to modify the surface so that the fluidity is greater than 20%.

Abstract

The invention relates to a multiple anti-fake carbon powder in an anti-fake material. The multiple anti-fake carbon powder is prepared through adding anti-fake materials into a commercially-available polymer resin, polypropylene wax, a charge adjustment agent, a pigment, silica, dimethyldichlorosilance and hexamethyldisilazane, mixing, extruding, crushing, sieving and the like. The anti-fake materials comprise long and short wave ultraviolet excitation fluorescence, infrared excitation luminescence and chemical discoloration anti-fake materials, and sunlight excitation color-variable, DNA and intelligent spectrum anti-fake materials. The multiple anti-fake carbon powder is suitable for various documents, notes, files and analogues. The multiple anti-fake carbon powder has the advantages of multiple anti-fake functions, reaching of multiple anti-fake purposes through one-time printing, satisfying of different-layering identification requirements, high anti-fake capability, and effective improvement of the anti-fake difficulty.

Description

technical field [0001] The invention belongs to multiple anti-counterfeiting toner in anti-counterfeiting materials, that is, the anti-counterfeiting toner containing multiple anti-counterfeiting functions. Background technique [0002] With the improvement of office automation and informatization level, anti-counterfeiting technology and informatization are organically combined. The signing, use and management of important bills and vouchers need to strengthen anti-counterfeiting, and the signature and seal of archive documents are also automatically printed by laser printers. Instead of traditional manual operation, but the toner with anti-counterfeiting function used by laser printers on the market is single anti-counterfeiting function, low technical content, easy to imitate. Technical content and counterfeiting difficulty are imperative. Contents of the invention [0003] In order to overcome the shortcomings of the existing anti-counterfeiting toner, such as low tec...
