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

[0028] Select 96 parts of latex 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), 3 parts of wax, and 15 parts of silicon dioxide.

[0029] Put the above-mentioned latex polymerized polymer resin, red pigment and wax together, and stir evenly to make a mixed solution;

[0030] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 250°C;

[0031] 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;

[0032] Finally, put the screened granular material into the mixer, add silicon dioxide, and mix evenly to make red toner.

no. 2 example

[0034] Select 70 parts of latex polymeric 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, 2 parts of polypropylene wax, 7 parts of silica, 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;

[0035] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 160°C;

[0036] 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;

[0037] Finally, put the screened granular material into a mixer, add silicon dioxide, hexamethyldisilazane and dimethyldichlorosilane, and mix evenly to make red toner.

no. 3 example

[0039] Select 85 parts of latex polymer resin, 10 parts of red pigment, 5 parts of wax, 11 parts of silicon dioxide, 3 parts of hexamethyldisilazane and 3 parts of dimethyldichlorosilane. Wherein: said latex polymeric polymer resin is the product of Wuxi Xishen Daily Chemical Products Factory; said wax is polyethylene wax;

[0040] 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 300°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 silicon dioxide, hexamethyldisilazane and dimethyldichlorosilane, and mix evenly to make red toner.

Abstract

The invention discloses a colorful anti-counterfeiting dry toner and preparation method thereof, specially a colorful anti-counterfeiting dry toner for color copying machine, color printer, colour facsimile apparatus, colorful digit integrated machine and chromatic press and preparation method thereof. The dry toner takes the latex polymerized polymer colophony, colouring paint, wax and exterior additive as materials. Firstly the latex polymerized polymer colophony, colouring paint, fluorescent powder and wax are mixed together, uniformly agitated to produce a mix solution; and then a spray drying machine is used to spray and dry the mix solution into granular material at the temperature from 160 to 300 DEG C; finally, an airflow hierarchical equipment is adopted to execute hierarchical screen selecting to the granular material, and an exterior additive is added to produce the dry toner by uniform mixing. The color toner not only has low production cost, but also will not pollute the environment.

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. ...
