Problems solved by technology

Since this kind of color toner needs to be cleaned with a large amount of clean water during the production process, and 50-100 tons of clean water is needed for each ton of product produced, not only the waste of water resources is serious, the production cost is high, but also the waste water after cleaning is discharged out, it will pollute the environment

no. 1 example

[0034] Select 96 parts of latex polymeric polymer resin (produced by Wuxi Xishen Daily Chemical Products Factory, also known as latex (emulsion) resin), 6 parts of red pigment (also known as magenta), 20 parts of ultraviolet fluorescent powder, 3 parts of wax, 12 parts of silica.

[0035] Put the above-mentioned latex polymer resin, red pigment, wax, and ultraviolet fluorescent powder together, stir evenly, and make a mixed solution;

[0036] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 250°C;

[0037] After that, the above-mentioned granular materials are screened by air classification to remove particles with a particle size greater than 12 microns and less than 1 micron;

[0038] Finally, put the screened granular material into the mixer, add silicon dioxide, and mix evenly to make red toner.

no. 2 example

[0040] Select 70 parts of latex polymer resin (produced by Wuxi Xishen Daily Chemical Products Factory or Wuxi Yusheng Chemical Co., Ltd., also known as latex (emulsion) resin), 5 parts of red pigment, 8 parts of infrared fluorescent powder, 2 parts of Polypropylene wax, 3 parts of charge regulator, 0.5 parts of hexamethyldisilazane and 0.5 parts of dimethyldichlorosilane. First put the latex polymer resin, red pigment and wax together, stir evenly to make a mixed solution;

[0041] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 160°C;

[0042] Afterwards, the above-mentioned granular materials are classified and screened using airflow classification equipment to remove particles with a particle size greater than 12 microns and less than 1 micron;

[0043] Finally, put the screened granular material into a mixer, add hexamethyldisilazane and dimethyldichlorosilane, and mix evenly to make red toner.

no. 3 example

[0045] Select 85 parts of latex polymer resin, 10 parts of red pigment, 15 parts of infrared phosphor, 2 parts of charge regulator, 5 parts of wax, 3 parts of hexamethyldisilazane and 3 parts of dimethyl Dichlorosilane. Wherein: said latex polymeric polymer resin is the product of Wuxi Xishen Daily Chemical Products Factory; said wax is polyethylene wax;

[0046] First put the latex polymer resin, red pigment and wax together, stir evenly to make a mixed solution;

[0047] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 300°C;

[0048] Afterwards, the above-mentioned granular materials are classified and screened using airflow classification equipment to remove particles with a particle size greater than 12 microns and less than 1 micron;

[0049] Finally, put the screened granular material into a mixer, add hexamethyldisilazane and dimethyldichlorosilane, and mix evenly to make red toner.

Abstract

The invention discloses an anti-counterfeit color ink powder and a preparation method thereof and concretely provides the anti-counterfeit color ink powder used for a color duplicating machine, a color printer, a color electrograph, a color digital integral machine and a color printing machine and the preparation method thereof. The anti-counterfeit color ink powder is made from the raw materials of latex polymerized macromolecular resin, colored pigment, electric charge regulator, phosphor powder, wax, external additive etc. The latex polymerized macromolecular resin, the colored pigment, the electric charge regulator, the phosphor powder and the wax are put together to be mixed uniformly and made into a mixed solution, and then a spray drier is used for spraying and drying the mixed solution into granular material under the temperature between 160 DEG C and 300 DEG C. Then the granular material is processed for a grading filtering by an air current grading device, and the external additive is added to be mixed uniformly to be made into the anti-counterfeit color ink powder. The color ink powder not only has the low production cost but also can not cause the environmental pollution.

Description

technical field [0001] The present invention relates to color toner and its preparation method. Specifically, it relates to color toner for color copiers, color printers, color facsimile machines, color digital all-in-one machines and color printing machines, and a preparation method thereof. Background technique [0002] At present, the color toners used in color copiers, color printers, color fax machines and color printing machines are usually chemically synthesized polymerized toners. This chemically polymerized toner is mainly made of other auxiliary materials such as emulsion, pigment and crosslinking agent. The preparation method is as follows: first put emulsion, pigment, cross-linking agent and other auxiliary materials together, and uniformly stir to make granular materials. Then, acid and detergent are added to clean the granular materials, and the floating materials on the granular materials are washed away. Afterwards, the washed granular material is dried. ...
