Abstract
The present invention relates to a formula of novel ink capable of preventing alteration and a making technique thereof. The present invention has the key point that maltose oil is modified by glycerol so as to be used as the main component of a film-forming agent of the ink. Maltose oil, glycerol, ethylene glycol (or polyethyleneglycol) and azo series (or phthalocyanine series) water-soluble pigment are modified by glycerol so as to be used as the main formula; the maltose oil, the glycerol, the ethylene glycol (or polyethyleneglycol) and the azo series (or phthalocyanine series) water-soluble pigment are stirred, rolled, etc. so as to finally obtain the finished ink capable of preventing alteration. Shading of valuable bills printed by the ink can disappear within 1 to 2 minutes when law breakers uses chemical agents such as word eradicators, and thus, evidence incapable of being covered is formed; therefore, the ink of the present invention has very important function.
Description
The invention belongs to modification invention, relate in particular to a kind of ink special that can prevent to alter bill printing ink.
Usually printing valuable bills such as check, invoice, the employed printing ink of tax reciept are composite drying type printing ink.Generally be made up of major ingredient such as membrane-forming agent, pigment and siccative, the reference index of printing ink is, fineness should be below 20 μ m, and it is 5-13Pas that viscosity is used 40 ℃ of measured values of Haake viscometer, and nominal is measured dryness between 20-60 minutes for 80 ℃.The pattern and character drying of being printed by this printing ink is because siccative and airborne oxygen effect, contained insatiable hunger is closed unsaturated double-bond polymerization in twos in the lipid acid sylvic oil and is formed fine and closely woven macromole film pigment is wrapped up in it in the membrane-forming agent, and securely attached on the stock.Because it is the macromole membrane structure is stable, water insoluble and make printed matter have good solvent resistance.Give the person's opportunity of breaking laws and commit crime simultaneously again, when they use the similar drug correction bill of ink-eraser, can't make former bill printed patterns occur changing, thereby the handler that often can deceive people to lack experience, the wealth of state and collective stolen.This is the serious problems that present valuable bills, particularly check, tax reciept are faced with.
The objective of the invention is to design a kind of printing ink of anti-correction, reach anti-purpose of altering thereby can under the effect of correction fluid, lose fundamental design.
Design key of the present invention is to change the character change of the existing component of printing ink with insoluble macromole barrier film, and adopt suitable water-soluble pigment to make it under the effect of oxygen and light, produce the variation of fading, thereby the law-breaker is had no way of doing it in the destroyed back of film forming.By a large amount of screenings and test, finally selected to mix the membrane-forming agent of back preparation by glycerine and maltose, name is called glycerin modification Fructus Hordei Germinatus sugar and oil, select for use azo system or phthalocyanine system to do water-soluble pigment, add that glycerine, ethylene glycol (or polyoxyethylene glycol) cooks viscosity modifier and siccative, thereby make water miscible printing ink.
Wherein glycerin modification Fructus Hordei Germinatus sugar and oil is the key ingredient of this water-soluble safety ink of preparation, and it is to be made by glycerine and maltose Hybrid Heating.Glycerol molecule hydroxyl and maltose hemiacetal group dehydration combined reaction formula is as follows in the reacting by heating:
This resultant has well to mix to glycerine pieces together performance, is the main film forming substance of this patent invention printing ink.For guaranteeing that filmogen accounts for major ingredient in the resultant of reaction, the mole number of participating in the glycerine of reaction must be more than or equal to the mole number of maltose.Consumption according to above reaction formula glycerine should be more than or equal to 0.269 with the ratio of the consumption of maltose, and through the selected glycerine precentagewise batching at least 30% of repetition test, nearly 70% also can.Promptly in following ratio prescription:
Glycerine 30-70%
Maltose 70-30%
It is as follows that the spy provides embodiment: embodiment 1234 glycerine 30% 45% 50% 70% maltose 70% 55% 45% 30%
The manufacture craft of glycerin modification Fructus Hordei Germinatus sugar and oil is carried out with reference to following steps: (1) mixes glycerine and maltose by above said proportioning and puts into the reactor heating.(2) Heating temperature is 150 ℃-200 ℃, and the hold-time is 0.5-2 hours, all overflows to water vapour.(3) measuring its viscosity number 40 ℃ of temperature with the Haake viscometer should be between 35-45Pas, and it is standby to be the finished product barrelling.In the above course of processing except that proportioning raw materials The key factor be to consider that maltose molecule often contains the crystal water of a molecule, and the condensation reaction between glycerine and the maltose also can generate water, make reaction thoroughly, key is to remove water purification.This is because of glycerin modification Fructus Hordei Germinatus sugar and oil Stability Analysis of Structures and contains a large amount of hydroxyls, and is soluble in water.The quality that guarantees product must thoroughly be eliminated the water that generates.
Glycerin modification maltose is to form main raw material of the present invention, also is key of success.Be to guarantee printing adaptability and other physical and chemical performance of safety ink, through the selected consumption of repetition test be gross weight 20-60% between.Glycerine, ethylene glycol (or polyoxyethylene glycol) class high boiling solvent are mainly used to adjust the rheological property of printing ink, and reach quick-drying purpose by the perviousness of this kind solvent.Thereby its total consumption in printing ink is controlled at 10-50% proper.Azo system or phthalocyanine are that water-soluble pigment is the hue component of printing ink, also are critical materialses of the present invention, and the total amount per-cent of pigment in printing ink is proper between being controlled at 10-30%.Azo system or phthalocyanine are that the color of water-soluble pigment is because the vision response that azo-group ketone phthalocyanine structure produces the selectivity absorption of light.Under the strong oxidizer effect, azo-group, ketone phthalocyanine structure can thoroughly be destroyed, and cause the completely dissolve of printed patterns thereby cause dyeing disappearing.When pigment runs into the liquid of correction fluid and so on, become film destroy, pigment spreads in water, thereby meet the oxygen decomposition base map decorative pattern that is imprinted on the false proof bill is disappeared, and has reached anti-correction purpose. further specifies to the present invention seeks to how to realize, now provides embodiments of the invention 5-9 (by weight percentage) embodiment 5678 91 water-soluble dyes 12 25 18 15 302 glycerin modification Fructus Hordei Germinatus sugar and oils 50 40 30 25 203 glycerine 30 25 35 50 404 ethylene glycol 8 10 10 polyethylene glycol 7 10
