Abstract
The disclosed preparation method for red carbon powder of color copier comprises: selecting material as 4-8 pigment red, 2-4 permanent peach, 80-90 polyester resin, 2-8 polypropylene wax, 2-4 charge regulator, 1-3 dimethyldichlorosilane, and 6-7 hexamethyldisilazane; mixing, extruding, smashing, and sieving. This invention can reduce cost and machine fault, and provides sharp file.
Description
(1) technical field
The present invention relates to a kind of carbon dust and preparation method thereof.Specifically, be to be used for red powdered carbon for color copier that duplicates by colored manuscript or colour picture and preparation method thereof.
(2) background technology
At present, the carbon dust that uses on the color copy machine, its Main Ingredients and Appearance resin all are to adopt styrene and acrylic acid bipolymer.There is following problem in the color copy machine carbon dust that utilizes this resin to make as primary raw material: in the production run, be difficult to pulverize the big and out-of-shape of particle.Because particle is big and out-of-shape, during duplicating, is difficult to answering equably on paper, not only imaging effect is relatively poor, and the consumption of carbon dust is many, use cost is higher.Because styrene and acrylic acid bipolymer have peculiar smell, make the carbon dust of making that peculiar smell also be arranged again, be unfavorable for environmental protection.
(3) summary of the invention
The problem to be solved in the present invention provides a kind of red powdered carbon for color copier.This red carbon powder, not only particle is little, regular shape, imaging effect are good, and consumption is few when duplicating, use cost is low.
Another problem that the present invention will solve provides a kind of method for preparing red powdered carbon for color copier.
For addressing the above problem, the present invention takes following technical solution:
Red powdered carbon for color copier of the present invention is made up of the raw material of following parts by weight:
4～8 parts of sun-proof bright red, solid pink 2～4 parts forever; 80～92 parts in vibrin; 2～8 parts of polypropylene waxes; 2～4 parts of charge adjusting agents; 6～7 parts of 1～3 part of dimethyldichlorosilane and hexamethyldisilazanes.Vibrin wherein is in terephthalate: the bipolymer that the ratio reaction of isophthalic acid ester=2: 8 forms.
The method for preparing red powdered carbon for color copier may further comprise the steps:
(1) earlier with the sun-proof bright red, solid pink, vibrin, polypropylene wax and charge adjusting agent are poured in the mixing roll forever, through evenly mixing, make compound;
(2) more above-mentioned compound is dropped in the extruding machine, under 90～150 ℃ temperature, compound is extruded compacting in flakes; Then, with sheet compound cooling to 40～45 ℃ and be ground into fragment;
(3) afterwards, with comminutor above-mentioned fragment is ground into the flour that particle diameter is 30～50 μ m;
(4) afterwards, above-mentioned flour is further pulverized with comminutor, and carry out classification successively, separation, collection, obtaining particle diameter is the semi-manufacture particle of 7～9 μ m;
(5) again after, add dimethyldichlorosilane and hexamethyldisilazane, with 850～950 rev/mins mixing rolls mixing 3～4 minutes, make its flowability greater than 20%;
(6) last, sieve with 200～250 eye mesh screens, make red powdered carbon for color copier.
Adopt above scheme, have the following advantages:
Because the used resin of red carbon powder of the present invention is a vibrin, this resin is according to terephthalate: the ratio reaction of isophthalic acid ester=2: 8 forms, with this resin with sun-proof bright red, raw materials such as solid pink, polypropylene wax, charge adjusting agent, dimethyldichlorosilane and hexamethyldisilazane forever, through mixing, extrusion molding, pulverize and red carbon powder that step such as sieve is made, pulverize the less and comparison rule of particle in the production run easily.Because the less and comparison rule of particle during duplicating, is formed four kinds of Essential colour with yellow, black, cyan carbon dust, can be equably attached on the paper, not only imaging effect is good, and consumption is few, use cost is lower.Again because used resin is a vibrin; and this resin is according to terephthalate: the ratio reaction of isophthalic acid ester=2: 8 forms; terephthalate wherein and isophthalic acid ester free from extraneous odour, the feasible black carbon powder of making is free from extraneous odour also, helps environmental protection.
