Description
Technical field
The invention belongs to the multiple anti-fake carbon dust in anti-fake material, be and contain multiple anti-fraud functional false proof carbon dust.
Background technology
Along with office automation, the level of IT application improve, anti-counterfeiting technology and informationization are combined, the autographed copy sale of important bill, voucher, use, managerial demand are strengthened false proof, the signature of archives document, affixing one's seal also replaces traditional manual operations with the laser printer automatic printing, but the anti-fraud functional carbon dust that has that laser printer is used in the market is single antiforge function, with low content of technology, easily imitated, raising along with scientific and technological level, some lawless persons seize the opportunity and stir up trouble, and technology content and the counterfeit difficulty of strengthening anti-fake product are imperative.
Summary of the invention
Existing false proof carbon dust is with low content of technology in order to overcome, easy imitated, shortcoming that anti-counterfeiting power is low, the object of the present invention is to provide a kind of multiple anti-fake carbon dust of novel high anti-counterfeiting performance.Has the false proof and expert's anti-counterfeit recognition function of the distincter public.The false proof reliability of this new style toner is strong, and identification and check are easy, and display effect is unique and distinct, and because complicated process of preparation, difficulty are difficult for greatly copying.
The technical scheme that multiple anti-fake carbon dust technical solution problem of the present invention adopts is: add anti-fake material in commercially available macromolecule resin, polypropylene wax, charge adjusting agent, pigment, silicon dioxide, dimethyldichlorosilane, hexamethyldisilazane, the part by weight that raw material forms is as follows: anti-fake material 15-50%, macromolecule resin 30-70%, polypropylene wax 4-9%, charge adjusting agent 3-10%, pigment 0.5-20%, silicon dioxide 0.1-0.5%, dimethyldichlorosilane 2-5%, hexamethyldisilazane 5-8%, and process by following steps:
(1) macromolecule resin, polypropylene wax, pigment, charge adjusting agent and anti-fake material are evenly mixed in mixer, make compound;
(2) more above-mentioned compound is dropped in extruding machine, and slowly heating, with above-mentioned compound compacting in flakes, coolingly be ground into powder with coarse-cracking machine afterwards at the temperature of 100-155 ℃;
(3) afterwards, with fine powder machine, above-mentioned particle is further pulverized, and carried out classification, separation, collection, obtain the primary products that particle diameter is 5-12 μ m;
(4) add silicon dioxide, dimethyldichlorosilane and hexamethyldisilazane, and mix with mixer, carry out surface modification and make its mobility greater than 20%.
(5) screen with 150 purpose sieves, make the multiple anti-fake blue carbon powder.
(6) check, packing.
Pigment can be respectively black, red, yellow, blue pigment, and what select that the 5-20% black pigment makes is namely the multiple anti-fake black carbon powder; What select that the 5-20% red pigment makes is namely the multiple anti-fake red carbon powder; What select that the 5-20% blue pigment makes is namely the multiple anti-fake blue carbon powder; What select that the 5-20% yellow uitramarine makes is namely the multiple anti-fake Yellow carbon powder; What select that the 0.5-3% yellow uitramarine makes is namely the multiple anti-fake colorless carbon powder.
Anti-fake material is two or more anti-fake material in long wave ultraviolet fluorescence excitation anti-fake material, short-wave ultraviolet ray excited fluorescence falsification preventing material, day optical excitation color-changing anti-counterfeit material, the luminous anti-fake material of infrared excitation, chemical stain anti-fake material, DNA anti-fake material, intelligence spectrum anti-fake material.
Owing to having added simultaneously multiple anti-fake material in the multiple anti-fake carbon dust, can show as multiple antiforge function, well and because anti-fake material kind, the quantity of adding can be selected arbitrarily, the antiforge function that shows is also different, this is of paramount importance.
It is different that ultraviolet excited fluorescence anti-fake material in the present invention is pressed the wavelength of excitation source, can be divided into shortwave and excite (excitation wavelength is 254nm) fluorescence falsification preventing material and long wave to excite (excitation wavelength is 365nm) fluorescence falsification preventing material two classes.
Infrared excitation luminescent material in the present invention refers to up-conversion luminescent material, both under far red light (as 980 nanometers) irradiation, sends the material of visible light.Can send infrared Huang, infrared green two kinds of colors (namely under 980nm excites, can send bright-coloured yellow, green or redness).
Day optical excitation color-changing anti-counterfeit material in the present invention, for issuing in sunshine (also can at ultraviolet excitation) irradiation the chromatic effect that changes, can from colourlessly redden, green, purple, blue, yellow isochrome, also can variation from coloured to coloured, this type of false proof carbon dust identification simple and fast, both can any instrument, with the naked eye just can distinguish the true from the false in the sun.Can be used as the popular false proof discriminating of a line, also can excite the generation change color with the ultraviolet currency detection lamp, tell truth from falsehood.
Intelligence spectrum anti-fake material in the present invention is to add one or more metallic elements or their organic complex and mineral compound in carbon dust, make it send X-fluorescence under the effect of intelligent spectrum X fluorescence identifier excitation source, measure its energy, intensity and differentiate kind, the content of the element that adds, and the false proof purpose of real the present invention.
Chemical stain anti-fake material in the present invention is the special compound that adds setting in carbon dust, through the reagent that specific Antiforging pen adopts, smears a kind of deciphering chemical reagent then on printing, duplicating or printing figure message, demonstrates immediately hidden picture and text.
The false proof starting material of DNA in the present invention are the DNA material of the suitable production carbon dust of especial manufacture, can utilize instrumentation to differentiate, identify arbitration as government administration section monitoring, expert.
Beneficial effect in the present invention is: the anti-fake material that adds two or more in carbon dust, the carbon dust of producing according to the carbon dust technical indicator of routine, this is the higher false proof carbon dust of a kind of scientific and technological content, because false proof raw material types configuration is unique, various materials influence each other and mutually restrict, for reaching mutual unification, mutually coordinate and keeping separately characteristics, complex manufacturing and technical difficulty are high, and anti-risk difficulty is huge. and this kind carbon dust has multi-thread antiforge function: i.e. a line anti-counterfeiting technology of masses' identification: the functions such as day phototropic; Two wires anti-counterfeiting technology with the false proof apparatus identification of cylinder list: Ultraluminescence is false proof, the infrared anti-false function; The functions such as three line anti-counterfeiting technology: DNA with the identification of the false proof apparatus of Special professional are false proof, chemistry is false proof, length ripple fluorescence falsification preventing, intelligence spectrum are false proof.
