Abstract
The invention discloses a dry-type and physical colorized ink powder and a preparation method thereof. The colorized ink powder is prepared by the following raw materials according to parts by weight:85 to 90 parts of polyester resin, 4.0 to 5.0 parts of color pigment, 1.0 to 2.0 parts of charge control agent, 2.0 to 3.0 parts of polyethylene wax and 0.6 to 1.0 part of silicon dioxide, wherein the softening temperature of the polyester resin ranges from 110 to 125 DEG C, and the melting point of the wax ranges from 105 to 110 DEG C. The preparation method includes the following steps: firstly, the color pigment, the polyester resin, the charge control agent and the polyethylene wax are mixed in a high-speed mixer; secondly, the mixture is processed into pieces by a mixing roll through mixing at the temperature ranging from 140 to 150 DEG C, and then is processed by the operation of coarse crushing; thirdly, the operations of micro-crushing and classification are carried out by an airflow crushing classifier so as to control the particle size to range from 6 to 8 mum; and finally, powder is led into the high-speed mixer, and the silicon dioxide is added to and mixed with the powder at high speed. The preparation method of the invention is comparatively simple, avoids environmental pollution caused by wastewater, the production cost is lower, the reproducibility of primitive colors is good, and printed or coped colorized pictures are much more vivid.
Description
Described technical field
The present invention relates to a kind of ink powder and preparation method thereof, be meant color toner that is applicable to digital color compounding machine, multifunctional colour digital duplicating machine, digital color duplicating, Printing machine and preparation method thereof particularly.
Background technology
At present, the color toner that uses on all digital color compounding machines, multifunctional colour digital duplicating machine, digital color copier, the Printing machine all is to adopt polymerization (emulsion method and suspension method) preparation.Its preparation method is: earlier monomer and emulsion are carried out premixed, carry out polyreaction then in reactor, polyreaction is carried out filtered water and is washed after 20 hours, behind the buoyant on the flush away granular material, again particle is carried out vacuum drying.At last, carry out classification and add silicon dioxide and mix.Because need a large amount of clear water to clean in the polymerization production run, the 50-100 ton clear water that approximately needs per ton cause the waste of water resource and bigger environmental pollution, and production cost is too high.Particularly vacuum drying needs the electric energy heating, and beginning humidity is 35%-45%, and finishing humidity is 0.00%, need more than 60 hours drying time, caused the rising and the powder granularity scope of production cost can only be controlled between the 2-12 μ m thus, caused resolution low, the color reductibility is bad.
Summary of the invention
The present invention's purpose is to overcome the above-mentioned deficiency of prior art, cyan, magenta, yellow, four kinds of ink powders of black and preparation method thereof are provided, four kinds of color toner matching performances are good, the text and the image that can print copying go out multiple color, image is more clear, true to nature, and cost is low, and is pollution-free in the manufacture process.
For reaching above-mentioned purpose, the present invention takes following technical scheme:
The present invention is made up of the raw material of following weight portion:
Alkyd resin: 85-90; Color pigment: 4.0-5.0; Charge control agent: 1.0-2.0; Tissuemat E: 2.0-3.0; Silicon dioxide: 0.6-1.0.
Wherein: its softening temperature of alkyd resin: 110 ℃-125 ℃, the fusing point of wax: 105 ℃-110 ℃, color pigment is cyan, redness, yellow, black.
The preparation method of color toner of the present invention:
Earlier color pigment is placed in the high-speed mixer with alkyd resin, charge control agent, Tissuemat E and mixes, mixing in blocks and carry out coarse crushing with mixing roll under 140～150 ℃ of temperature then; Carry out broken, the classification of micro mist with the jet mill grinding machine again, its granularity is controlled between the 6-8 μ m; At last, granularity is dropped into high-speed mixer at the powder of 6-8 μ m, add silicon dioxide then and carry out high-speed mixing and get final product.
The present invention takes technique scheme, have following beneficial effect: the present invention chooses needed raw material alkyd resin, pigment of all kinds, charge control agent, Tissuemat E, with airtight 4-5 minute time of high-speed mixer mixing of its disposable input, pulverize extension set with the closed gas-flow grader through melting again after sheet is rolled in mixing, add silicon dioxide mixing 5-10 at last and get final product second.The preparation method is simple relatively because the production overall process is all worked under air-tight state and not water clean, avoided the environmental pollution that water wasting caused, and the power consumption of per kilogram color toner only is 7 degree, production cost is lower.Particularly production run all adopts computer control temperature, and it is the narrowest to have guaranteed that powder granularity controls to, and particle mean size is at 6-8 μ m, and former color reproduction is good, and it is more true to nature to beat the coloured image that (answering) print off.
