Problems solved by technology

Since this kind of black 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 of water after cleaning discharge will pollute the environment

Embodiment Construction

[0024] first embodiment

[0025] Choose 96 parts of latex polymer resin, 0.2 part of black pigment, 3 parts of charge regulator, and 2 parts of silicon dioxide; wherein: said latex polymer resin is a product of Wuxi Xishen Daily Chemical Products Factory; Say the charge regulator is a metal salicylate complex;

[0026] First put the latex polymerized polymer resin, the charge regulator and the black pigment together, and stir evenly to make a mixed solution;

[0027] Then use a spray dryer to spray dry the above mixed solution into granular materials at a temperature of 250°C;

[0028] After that, the above-mentioned granular materials are screened to remove particles with a particle size greater than 13 microns and less than 1 micron;

[0029] Finally, put the screened granular material into the mixer, add silicon dioxide, and mix evenly to make black toner.

[0030] second embodiment

[0031] Select 83 parts of latex polymer resin, 6 parts of black pigment, 7 parts of bl...

Abstract

The present invention disclose a black ink powder and its preparation method.Specifically, it is a black ink powder and preparation method for color copies, color printers, color fax machines and color printed machines.It uses latex polymer resin, black pigment, black magnetic powder, charge regulator, wax, water -based dispersant, silicon oxide, hexum -based two silicane, and dihalisane, and other raw materials.Latex polymerization high -molecular resin, charge regulator, black pigment, black magnetic powder, water -based dispersant and wax are placed together, stir well to make a mixed solution.Then use a spray dryer at a temperature of 160 to 300 ° C to spray the above mixed solution into a granular material.After that, the above -mentioned granular materials were screened, and silicon dioxide, hexal aimal sircitanane and dihalmchloroblotosilles were added to be made.The black ink powder not only has low production costs, but also does not cause pollution to the environment.

Description

technical field [0001] The invention relates to a toner and a preparation method thereof. Specifically, it relates to black toner for color copiers, color printers, color facsimile machines and color printing machines and a preparation method thereof. Background technique [0002] At present, the black toner used in color copiers, color printers, color fax machines and color printing machines is emulsion polymerized toner. This emulsion polymerization 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. Finally, it is prepared by adding auxiliary materials such as sili...
