Abstract

The present invention discloses cyan carbon powder for a color laser printer and a preparing method thereof. The cyan carbon powder is prepared from 85 to 95 parts of polyester resin, 5 to 10 parts of polyacrylonitrile, 3 to 9 parts of charged current, 7 to 12 parts of silicon dioxide, 3 to 10 parts of phthalocyanine blue and 0.5 to 1 part of azo dye by the steps of mixing, extrusion molding, crushing, sieving, etc. With the adoption of the cyan carbon powder, printed documents and pictures are clear without fading; in addition, the use cost can be reduced, and the fault rate of a printer can be decreased.

Description

Multicolour laser printer cyan carbon dust and preparation method thereof

(1) technical field

The present invention relates to a kind of carbon dust and preparation method thereof.Specifically, be to be used for multicolour laser printer cyan carbon dust 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 print colored manuscript, 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 lower, unintelligible; The 3rd, because the water absorbing properties of ink is poor, feasible manuscript and the image 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 cyan carbon dust.Use this cyan carbon dust, not only manuscript of Da Yining and clear image, colour-fast also can reduce use cost, reduce printer fault.

Another object of the present invention provides a kind of method for preparing multicolour laser printer cyan carbon dust.

Above-mentioned purpose of the present invention is realized by following technical solution:

Multicolour laser printer cyan carbon dust of the present invention is made up of the raw material of following parts by weight:

85～95 parts in vibrin; 5～10 parts of Poly Propylene Waxes; Charged 3～9 parts; 7～12 parts of silicon-dioxide; 3～10 parts of phthalocyanine blues; 0.5～1 part of azoic dyestuff.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 cyan carbon dust of the present invention may further comprise the steps successively:

(1) earlier with vibrin, Poly Propylene Wax, 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 5.5～7.5kg/m with pressure ²Air carry out comminution by gas stream, and carry out classification with 5500～6000 rev/mins grading machine, handle with trap, obtaining particle diameter is the flour work in-process of 5～8 μ m;

(5) again after, add silicon-dioxide, 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 cyan carbon dust of the present invention.

Adopt above scheme, have the following advantages:

Since the present invention be with raw materials such as vibrin, Poly Propylene Wax, charged, silicon-dioxide, phthalocyanine blue and azoic dyestuff through mixing, extrusion molding, pulverize and dry type cyan carbon dust 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 black, red, Yellow carbon powder, 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.
