Abstract
The invention discloses a yellow durability anti-counterfeit developer of a colored laser printer and a preparation method thereof. The developer is prepared from the following raw materials in parts by weight: 4-8 parts of iron oxide yellow, 1-2 parts of permanent yellow, 10-20 parts of ultraviolet fluorescent powder, 80-90 parts of styrene-acrylic resin, 4-6 parts of poly propylene wax, 2-4 parts of charge regulating agent, 2-5 parts of dimethyldichlorosilane, 11-13 parts of hexamethyldisilazane, and the like through the steps of mixing, extrusion molding, pulverizing, screening, and the like. When the yellow durability anti-counterfeit developer of a colored laser printer is used for printing color texts and yellow marks, the yellow durability anti-counterfeit developer has bright and clear color, and compared with colors of the frequently used signature, the developer has no color difference, can meet the requirements on signatures and seals in file writs, and is particularly suitable for printing marks and file writs such as signatures and seals.
Description
Technical field
The present invention relates to a kind of printer ink powder and preparation method thereof.Be to be used for the Yellow durability anti-counterfeit developer of colored laser printer preparation method extremely of printing file, material of picture and text or security stamp specifically.
Background technology
Along with progress of science and technology, the office automation level is more and more higher, and the various archives documents of comprise signature, affixing one's seal are also printed automatically with laser printer gradually and replaced traditional manual operations.Adopt the automatic printing file document of laser printer, to having relatively high expectations of developer, the archives document lovely luster that comprises signature, affixes one's seal that requirement is printed is beautiful, with the actual no color differnece of comparing.
No. 2006100976921 application for a patent for invention instructionss of China disclose a kind of durable false-proof yellow carbon powder for laser printer.This carbon dust is by raw materials such as iron oxide yellow, ultraviolet fluorescence powder, vibrin, polypropylene wax, charge adjusting agent, dimethyldichlorosilane and hexamethyldisilazanes and make.Pigment wherein only has iron oxide yellow a kind of, and iron oxide yellow is an inorganic pigment, makes that the signature, the marking and the colored picture and text color and luster that print with this carbon dust are darker, smudgy, to compare aberration bigger with the color of stamped signature commonly used, is difficult to adapt to the signature in the archives document, the requirement of affixing one's seal.
Summary of the invention
The problem to be solved in the present invention provides a kind of Yellow durability anti-counterfeit developer of colored laser printer.With signature, the marking and colored picture and text that this Yellow durability anti-counterfeit developer of colored laser printer is printed, color and luster is beautiful, clear, with the actual no color differnece of comparing, can adapt to the signature in the archives document, the requirement of affixing one's seal.
Another problem that the present invention will solve provides a kind of method for preparing Yellow durability anti-counterfeit developer of colored laser printer.
For addressing the above problem, the present invention takes following technical scheme:
Choose the raw material of following parts by weight earlier:
4～8 parts of iron oxide yellows;
1～2 part of permanent yellow;
10～20 parts of ultraviolet fluorescence powders;
80～90 parts of styrene-acrylic resins;
4～6 parts of polypropylene waxes;
2～4 parts of charge adjusting agents;
2～5 parts of dimethyldichlorosilanes;
11～13 parts of hexamethyldisilazanes.
Described charge adjusting agent is the senior metal complex of DL-N24 type that Hubei Province ancient cooking vessel dragon chemical industry Ltd produces.
Then, iron oxide yellow, permanent yellow, ultraviolet fluorescence powder, styrene-acrylic resin, polypropylene wax and charge adjusting agent are poured in the mixing roll, mixed, make compound.
Under 90～150 ℃ temperature, above-mentioned compound is squeezed into sheet with extruding machine again.
Afterwards, the sheet compound is cooled off to 40～45 ℃, and be ground into fragment.
Afterwards, with comminutor above-mentioned fragment is ground into the flour that particle diameter is 30～50 μ m.
Afterwards, with comminutor above-mentioned flour is further pulverized, and carried out classification, separation, collection, obtaining particle diameter is the semi-manufacture particle of 7～9 μ m.
Again, add dimethyldichlorosilane and hexamethyldisilazane, and mixed 3～4 minutes, make its flowability greater than 20% with 850～950 rev/mins mixing roll.
At last, screen, make Yellow durability anti-counterfeit developer of colored laser printer with 200～250 purpose sieves.
Take such scheme, have the following advantages:
Since in the raw material of the present invention on the basis of adopting original inorganic pigment iron oxide yellow, added the organic pigment permanent yellow again, adopt inorganic pigment iron oxide yellow and organic pigment permanent yellow as toner, make the signature of printing with this developer, affix one's seal and colored picture and text, color is beautiful, clear, compare no color differnece with the color of stamped signature commonly used, thereby satisfied the requirement that resembles signature, affixes one's seal a class archives document.
