Description
Technical field
The present invention relates to paint for papers field, relate in particular to a kind of coating for three color water-mark fake-proof papers and preparation method thereof.
Background technology
In current anti-counterfeiting technology, widely used water marked paper adopts special chemical resin and special mode of printing to make, and cost is high, and gained water marked paper rough surface is uneven, matt, dim design.In addition, also can use watermark ink to form by printing the effect that water marked paper is the same, imitated threshold is extremely low, and antifalse effect is undesirable.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of watermark anti-counterfeiting clear patterns, antifalse effect is good and three color watermark anti-counterfeiting paint for papers and preparation methods of low cost of manufacture.
For solving the problems of the technologies described above, the technical scheme that invention adopts is, this three color watermark anti-counterfeiting paint for papers is comprised of following component by weight: 20～30 parts of titanium dioxide, 0.6～1.4 part of defoamer, 35～65 parts of PD converted starches; 4.5～9.5 parts of styrene-butadiene latexes, 0.4～0.8 part of fluorescent liquid agent, 13～19.6 parts, 0.08～0.12 part of black dyes and water.
A preferred version of the present invention is that this three color watermark anti-counterfeiting paint for papers is comprised of following component by weight: 25 parts of titanium dioxide, 1 part of defoamer, 50 parts of PD converted starches, 7 parts of styrene-butadiene latexes, 0.6 part of fluorescent liquid agent, 0.1 part of black dyes, 16.3 parts, water.
The concrete steps of preparing above-mentioned three color watermark anti-counterfeiting paint for papers are:
(1) water is joined in container, start and stir, then add PD converted starch to stir;
(2) heat temperature raising, insulation, cools; In this container, add successively titanium dioxide, defoamer, styrene-butadiene latex and stir again;
(3) in the most backward this container, add successively fluorescent liquid agent, black dyes and stir, obtaining this three color watermark anti-counterfeiting paint for papers.
By the above-mentioned three color watermark anti-counterfeiting coating that prepare, by transfer type coating method, this coating is coated with and is printed on paper, can obtain three color water-mark fake-proof papers.
Beneficial effect of the present invention is that this coating is easy to preparation, and the paper and the sight line that scribble this coating are formed to certain angle, when light is observed, it will be appreciated that paper appears security pattern clearly in one's mind.Because concealed anti-false pattern can only just can be seen when a direction is observed light, with duplicator, can not duplicate or camera can not be taken pictures, anti-counterfeiting performance is good.The paper that scribbles this coating is placed under ultraviolet source irradiation, the concealed anti-false pattern place that it will be appreciated that paper has strong blue fluorescence to occur, forms the colourless security pattern of blue fluorescence, leaves ultraviolet source and irradiates, the colourless security pattern of blue fluorescence disappears at once, and paper restores to the original state.Paper, to x ray fluoroscopy x, be it will be appreciated that to paper has the similar black watermark recovery appearing in one's mind.In sum, the water-mark fake-proof paper that uses this coating to make has three color watermark anti-counterfeiting patterns, and antifalse effect is good, is difficult to be imitated, and has also reduced low cost of manufacture.
