Abstract
The invention relates to a red ink powder and a preparation method thereof. The preparation method comprises the following steps: heating 30-90 parts of resin, 5-10 parts of red pigment, 0.1-5 parts of charge control agent and 1-30 parts of polypropylene wax to melt, stirring the molten materials to disperse evenly, performing spray granulation with an atomizer, cooling to obtain ink powder particles, adding flowable agent for modification and finally obtaining the ink powder product through air classification. The ink powder particles prepared by the invention has uniform particles, good low-temperature fixing effect, more than 90% of transfer printing rate small processing equipment investment, simple process operation, short flow, low production cost, and no effluent or exhaust gas emission which can pollute the environment in preparation process, and ultrafine and ultracoarse ink powder particles can be recycled to a melting kettle for reuse, thus making the most use of the raw materials.
Description
Technical field
The present invention relates to a kind of ink powder and preparation method thereof, be specifically related to a kind of colored some photographic equipment red ink powder and preparation method thereof.
Background technology
Raising along with the office demand, technicolo photographic equipment color laser printer, color copy machine etc. more and more are subjected to liking of user, need control the particle diameter of ink powder for reaching high-resolution requirement, need the ink powder of regular shape, good fluidity for reaching the purpose of developing preferably.But at present colored production major part with ink powder still adopts traditional physical crushing method, is about to various ink powders and prepares ink powder with raw material through technologies such as mixing, mixing, pulverizing, classification, outer dopings.Adopt the physics method to produce the ink powder complex process, energy input is big, and toner particles out-of-shape and cause mobile poor causes the cost increase simultaneously because of production procedure is long.Along with the expansion of market for ultra-fine ink powder demand, this technology more and more demonstrates its expensive drawback.
At these shortcomings, all the other small part producers have released chemical powder.The chemistry powder refers in the preparation the carbon dust that steps such as generally the process monomer mixes, initiation is synthetic, washing purification, drying, classification are prepared from.Though by this method obtain ink powder particle balling preparation shape, the equipment input is big, need a large amount of water clean toner particles post-synthesis phase, has drawbacks such as bigger pollution, efficient are low.
Chinese patent application numbers 200810024837.4, announced that name is called the patent of invention of " a kind of color toner and preparation method thereof ", this patent mainly is raw materials such as coloured wax material, wax, external additive to be joined make mixed solution in the polymerization macromolecule resin, under 160-300 ℃ temperature the mixed solution spraying is dried to granular material with spray dryer again.The shortcoming of this method is to add the ink powder raw material to the macromolecule glue Ruzhong not adding under the situation of any spreading agent, certainly will exist to disperse bad phenomenon; In addition, if polymer latex is non-water-based latex, also exist carbon dust can discharge organic solvent to shortcomings such as atmosphere pollute when drying, the polymer latex in the described carbon dust raw material of this patent has certain limitation.
Summary of the invention
At above-mentioned weak point, the invention discloses a kind of brand-new red ink powder manufacture method.Fundamental purpose provides that a kind of technological process is simple, uniform particles, the free of contamination ink powder of preparation process, and main technical schemes is as follows:
Red ink powder primary raw material among the present invention is resin, red pigment, charge adjusting agent, polypropylene wax, silicon dioxide.Wherein, resin is preferentially selected the viscoelasticity resin of fusing point between 80-170 ℃ of scope for use; Suitably improve the content of polypropylene wax, increase the low-temperature fixing characteristic of ink powder.During the preparation ink powder various raw materials are added in the molten-bath, heating is uniformly dispersed fused solution in constantly stirring; Pipeline by heat-insulation and heat-preservation between molten-bath and the atomizer is connected, fused solution is atomized into droplet through atomizer after by pipeline, be toner particles behind the cool drying, at last toner particles carried out modification and increase flowability, be required ink powder finished product after the classification.
Prepare red ink powder of the present invention and mainly adopt the following step:
(1) according to set deal resin, red pigment, charge adjusting agent, polypropylene wax are joined in the molten-bath, under stirring, add heat mixture to complete fusion and finely dispersed state;
(2) fused solution after being uniformly dispersed is through after having the pipeline of heat-insulation layer, under the pressure of 1-4Mp, be atomized into droplet by atomizer, the pressure parameter control toner particles that adopts is between the 4-10 micron, in addition, the mode that employing is atomized into drop can guarantee the toner particles regular shape for preparing, and uniform particles is good;
(3) ventilation stream air in the drop after atomizing from top to bottom, because spraying makes progress, the air-flow air is downward, in counter-current process, realize dry run, in addition, drop after the atomizing is sedimentation downwards under action of gravity, and lead to the cold flow air and go this moment, continues to finish the cool drying process; In addition, drying mode can also be selected the cooling of atomizer outer circulation water, circulating liquid nitrogen for use, and the multi-layer classification tower is any mode in the natural cooling step by step.
(4) in dried ink powder, add silicon dioxide, adopt 1000 rev/mins stirring machine to stir 5 minutes, adopt the flowability that can further increase ink powder after silica modified;
(5) at last with the ink powder classification, the ink powder of collecting the 4-10 micron is packaged into goods, is added in the molten-bath recyclingly after the ink powder that classification is removed is collected, and the cold flow air can be realized harmless treatment through behind the dust arrester.
Advantage of the present invention: whole process equipment drop into little, technological operation is simple, flow process is short, production cost is low, pollution-free in the preparation process, prepared toner particles is even, low-temperature fixing is effective, transferring rate reaches more than 90%.
