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

Color toner and preparation method thereof
Technical field
The present invention relates to color toner and preparation method thereof.Be color toner and preparation method thereof such as color copy machine, color printer, colour facsimile apparatus, colored digital all-in-one and chromatic printing machine specifically.
Background technology
At present, the color toner that uses on color copy machine, color printer, colour facsimile apparatus and the chromatic printing machine polymeric toner of chemosynthesis normally.This chemical polymerization ink powder is mainly made by other auxiliary material such as emulsion, pigment and crosslinking chemical.Its preparation method is that elder generation puts other auxiliary materials such as emulsion, pigment and crosslinking chemical together, through evenly stirring, makes granular material.Then, add acid and washing agent and granular material is cleaned the buoyant on the flush away granular material.Afterwards, the granular material through cleaning is carried out dried.At last, in the granular material that drying was handled, add auxiliary materials such as silicon dioxide, and evenly mix and make.Because this color toner needs to clean with a large amount of clear water in process of production, and one ton of product of every production just needs 50~100 tons of clear water, not only water resource waste is serious, production cost is higher, and the discharge of wastewater after cleaning comes out, and can pollute environment.
Summary of the invention
The problem to be solved in the present invention provides a kind of color toner, this color toner, and not only production cost is lower, and can not pollute environment.
Another problem that the present invention will solve provides the preparation method of above-mentioned color toner, and this method technology is simple, not only can avoid water resource waste, reduced production cost.
For addressing the above problem, take following technical scheme:
Color toner characteristics of the present invention are the raw materials that contain following weight portion:
70~96 parts of emulsion polymerization macromolecule resins;
0.5~10 part of colored pigment;
1~5 part in wax;
External additive: 1-15 part
Wherein: said emulsion polymerization macromolecule resin claims latex (emulsion) resin again; Wax is any one in polypropylene wax, Tissuemat E or the paraffin; External additive is meant: any mixing of a kind of, two kinds or three kinds among silicon dioxide, hexamethyldisilazane, the dimethyldichlorosilane three; Colored pigment is selected redness, black, yellow or blue pigment respectively for use.
The preparation method of color toner of the present invention contains following steps:
Earlier emulsion polymerization macromolecule resin, colored pigment and the wax of above-mentioned weight portion are put together, stir, make mixed solution;
Under 160~300 ℃ temperature, above-mentioned mixed solution spraying is dried to granular material with spray dryer again;
Afterwards, above-mentioned granular material is used the screening of air current classifying equipment, remove particle diameter greater than 13 microns, less than 1 micron particle;
At last, will drop in the mixer, and add the external additive of above-mentioned weight portion,, make color toner through evenly mixing through garbled granular material.
Described colored pigment is selected redness, black, yellow or blue pigment respectively for use.
Above scheme of the present invention has the following advantages compared to existing technology:
Because color toner of the present invention contains raw materials such as emulsion polymerization macromolecule resin, colored pigment, wax, external additive, and adopt spray drying process to make, need not clean in the production run, not only can avoid water resource waste, reduced production cost, and the pollution that does not have waste water to discharge, avoided waste water that environment is brought.
1, the ink powder that is to use airslide disintegrating mill tool method to make substantially both at home and abroad.Advantage: technology is mature on the whole.Shortcoming: granularity is irregular, power consumption is big, recovery rate is low, cost is high.
2, the world has factory of 1-2 family chemical method to produce ink powder.Advantage: the quality height, the powder degree is even, image is obviously clear.Shortcoming: investment is big, water consumption is big, cost of water treatment is high.
3, among the present invention with latex (emulsion) resin compound spray drying polymeric toner.Advantage: energy-saving and environmental protection, epigranular, recovery rate height.
Technology of the present invention belongs to the technology of the synthetic ink powder of spray drying process, but has avoided the technique waste water that the product washing produces in the chemical method in process of production, has accomplished wastewater zero discharge.
In technological process of the present invention, use suspension latex (emulsion) resin and ultrafine solids raw material.Wherein, latex (emulsion) resin suspending liquid particle diameter is below 5 μ m, its particle diameter of solid material is below 5 μ m, these suspension liquid raw material and solid material, mix according to a certain percentage, solid material is distributed in suspension latex (emulsion) resin equably, form content new suspension system uniformly, in spray-drying process, suspension material liquid forms little liquid grain after atomizing, surface area increases greatly, in hot-air flow, but the water flash evapn of 97~99.7% in the material, the resin in several seconds inner suspension material with solid material melting be in the same place, and form the particle of 2~30 μ m, semi-manufacture after spray-dried become the qualified product of particle diameter through air current classifying.
Do not need coloured magnetic, charge adjusting agent, three kinds of raw materials of aqueous dispersion among the present invention in the raw material, cost is lower.The property regulation of product can be adjusted realization by the last outer thing that adds, and technological process is simpler and more direct, and the easier regulation and control of properties of product significantly strengthen the printer adaptability of different manufacturers, model.
