Abstract
The present invention is black toner for color laser printer and its preparation process. The black toner is prepared with carbon black 5-10 weight portions, polyester resin 80-90 weight portions, polypropylene wax 4-8 weight portions, charging material 5-10 weight portions, silica 6-10 weight portions, phthalocyanine blue 0.5-3 weight portions, azo dye 0.5-3 weight portions zinc stearate 4-9 weight portions, and through mixing, extruding, crushing, sieving and other steps. Using the black toner can obtain fadeless clear graph and text in lowered printing cost and reduced printer fault rate.
Description
(1) technical field
The present invention relates to carbon dust and preparation method thereof.Specifically, be to be used for multicolour laser printer black carbon powder of printing color manuscript or colour picture and preparation method thereof.
(2) background technology
At present, the handle official business color printer of usefulness of people mainly is an ink-jet printer.The pigment that ink-jet printer uses is ink.Though utilize ink can go out colored manuscript by printer, have following problem as the ink-jet printer of pigment: the one, ink is volatile, consumption is many, use cost is higher; The 2nd, when body was not enough, the manuscript ink dot that prints was big, resolving power is low, unintelligible; The 3rd, because the water absorbing properties of ink is poor, feasible manuscript and the visual fugitive color that prints.In addition, use ink also easily to stop up printing head, make printer fault higher.
(3) summary of the invention
The object of the present invention is to provide a kind of multicolour laser printer black carbon powder.Use this black carbon powder, not only manuscript of Da Yining and clear image, colour-fast, also can reduce use cost low, reduce printer fault.
Another object of the present invention provides a kind of method for preparing the multicolour laser printer black carbon powder.
Above-mentioned purpose of the present invention is realized by following technical solution:
Multicolour laser printer black carbon powder of the present invention is made up of the raw material of following parts by weight:
5～10 parts of carbon blacks; 80～90 parts in vibrin; Cured 4～8 parts of polypropylene; Charged 5～10 parts; 6～10 parts of silicon-dioxide; 0.5～3 part of phthalocyanine blue; 0.5～3 part of azoic dyestuff; 4～9 parts of Zinc Stearates.Vibrin wherein is in vinylbenzene: the binary copolymerization resin that the ratio reaction of butyl acrylate=4: 1.2 forms.
The method for preparing multicolour laser printer black carbon powder of the present invention may further comprise the steps successively:
(1) earlier that carbon black, vibrin, polypropylene is cured, phthalocyanine blue, azoic dyestuff and charged pouring in the mixing roll, uniform mixing is made compound;
(2) more above-mentioned compound is dropped in the extruding machine, under 90～150 ℃ temperature, compound is extruded into fragment;
(3) afterwards, with pulverizer above-mentioned fragment is ground into the flour that particle diameter is 30～40 μ m;
(4) afterwards, be 6～7kg/m with pressure
2Air carry out comminution by gas stream, and carry out classification with 4800～5500 rev/mins grading machine, remove the flour that particle diameter is greater than or less than 9～10 μ m with trap, obtaining particle diameter is the flour work in-process of 5～8 μ m;
(5) again after, add silicon-dioxide and Zinc Stearate, with 900 rev/mins stirrers mixing 3～4 minutes, make its flowability greater than 20%;
(6) last, sieve with 250 eye mesh screens, make multicolour laser printer black carbon powder of the present invention.
Adopt above scheme, have the following advantages:
Because the present invention is raw materials such as, silicon-dioxide cured, charged with carbon black, vibrin, polypropylene, phthalocyanine blue, azoic dyestuff and zinc stearate through mixing, extrusion molding, pulverizes and dry type black carbon powder that step such as sieve is made, particle diameter is little, carried charge is high, consumption is few, use cost is low, the manuscript resolving power height that prints, clear, the manuscript that water-absorbent is strong, print is fugitive color not.In addition, use this carbon dust, also can reduce the failure rate of laser printer.It matches with red, spring, cyan carbon dust, by the heat setting type principle of solidification, can form up to ten million kinds of color dots, printablely goes out colored manuscript or image.
