Abstract
The invention relates to anti-counterfeiting coating with colored concealed variable patterns for paper and a method for preparing the anti-counterfeiting coating. The anti-counterfeiting coating comprises, by mass, from 2 to 6 parts of light calcium carbonate, from 3.5 to 8.5 parts of activated clay, from 15 to 25 parts of PD (polyether diols) starch adhesive, from 1.7 to 7.5 parts of antifoaming agent, from 7.5 to 12.5 parts of wheat starch, from 2 to 6 parts of resin color-developing agent, from 7.5 to 12.5 parts of styrene butadiene latex, from 2 to 6 parts of microcapsule color former, from 0.02 to 0.06 part of fluorescer, from 4 to 8 parts of thermochromic materials and from 26 to 36 parts of water. The prepared coating is coated on a paper surface so that anti-counterfeiting paper with colored concealed variable patterns is formed, at the moment, the colored concealed variable patterns have the color of the thermochromic materials and are changed to be colorless when the paper is heated to a certain temperature, the original color of the patterns is recovered after the paper is cooled down, and change of the color is obvious and speedy. In addition, if certain pressure is exerted to the colored concealed variable patterns, the concealed color-changing patterns can be displayed, but the color of the patterns at the stressed position is not changed along with temperature, and the original colored patterns are recovered at unstressed positions.
Description
Technical field
The present invention relates to a kind of coating and manufacture method thereof, relate in particular to coloured hidden change pattern anti-fake coating and manufacture method thereof for a kind of paper.
Background technology
False proof bill is mainly completed by body paper manufacture, coating processing, printing three phases.If have good anti-counterfeiting technology and form composite anti-fake at above-mentioned three phases, antifalse effect will be best, because fake producer will crack composite anti-fake technology, just must get together many-sided talent simultaneously, grasps multiple technologies, have multiple equipment.So, the action of fraud strengthens, and easily exposes, and fraud cost significantly rises, and even schemes without profit, and then reduces the generation of imitation behavior.
In prior art, only having watermark, safety line technology in paper-making process, there are the false tickets that fidelity is very high in the former, and the latter's cost is very high, is difficult to practicality; At printing stage, various smooth alternating temperatures become fluorescent ink can be purchased everywhere, and printing house much more extremely to make antiforge effect poor; At present, the temporary anti-counterfeit paint without high technology content.
Due to the counterfeit raising of using correlation technique, the paper such as bill, marketable securities, certificate certificate, mark mark require also more and more higher by the anti-counterfeiting technology of product, in order to meet this requirement, the anti-counterfeit paint that increases a kind of high-tech of coating before the printing of paper articles for use becomes current problem demanding prompt solution.
Summary of the invention
For above-mentioned shortcoming, the technical issues that need to address of the present invention are to provide coloured hidden change pattern anti-fake coating and manufacture method thereof for a kind of paper.
For achieving the above object, the technical solution used in the present invention is: coloured hidden change pattern anti-fake coating for a kind of paper, and its raw materials comprises the component of quality proportioning as described below: 2～6 parts of precipitated calcium carbonates; 3.5～8.5 parts of atlapulgites; 15～25 parts of PD amylans; 1.7～7.5 parts of defoamers; 7.5～12.5 parts of wheaten starches; 2～6 parts of resin color-developing agents; 7.5～12.5 parts of styrene-butadiene latexes; 2～6 parts of microcapsules colour formers; 0.02～0.06 part of fluorescer; Temperature becomes 4～8 parts of materials; 26～36 parts, water.
The first preferred version of the present invention, coloured hidden change pattern anti-fake coating for above-mentioned paper, its raw materials comprises the component of quality proportioning as described below: 4 parts of precipitated calcium carbonates; 5.5 parts of atlapulgites; 20 parts of PD amylans; 5.6 parts of defoamers; 10.5 parts of wheaten starches; 4 parts of resin color-developing agents; 10.5 parts of styrene-butadiene latexes; 4 parts of microcapsules colour formers; 0.04 part of fluorescer; Temperature becomes 6 parts of materials; 30 parts, water.
The second preferred version of the present invention, the color change interval that described temperature becomes material is-15～70 DEG C.
Further, the manufacture method according to above-mentioned paper with coloured hidden change pattern anti-fake coating, comprises the following steps:
(1) in material-compound tank, add water, start and stir, in stirring, add PD amylan, then through being heated to 90～95 DEG C, keep temperature 30 minutes, then be cooled to 50～60 DEG C;
(2) material-compound tank in above-mentioned steps (1) adds precipitated calcium carbonate, atlapulgite, defoamer, wheaten starch, resin color-developing agent, butadiene-styrene latex, microcapsules colour former in stirring successively wherein;
(3) continue to add successively fluorescer, temperature to become material in the material-compound tank in above-mentioned steps (2), stir, can obtain described coloured hidden change pattern anti-fake coating for paper.
Advantage of the present invention: the coating configuring is applied on paper, and forms coloured hidden change pattern anti-fake paper, now coloured hidden change pattern is the color of temperature change material, being heated while reaching uniform temperature, pattern becomes colorless, and recovers again original colored pattern after cooling, and change color is obvious and rapid; If place applies certain pressure at coloured hidden change pattern, this pattern can show the pattern of hidden change color, but pattern place herein can variation with temperature and variable color, and original colored pattern is recovered in the place of not exerting pressure.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Embodiment 1
The manufacture method of coloured hidden change pattern anti-fake coating for paper, comprises the following steps:
(1) take raw materials, and its raw materials comprises the component of quality proportioning as described below: 2 parts of precipitated calcium carbonates; 3.5 parts of atlapulgites; 15 parts of PD amylans; 1.7 parts of defoamers; 7.5 parts of wheaten starches; 2 parts of resin color-developing agents; 7.5 parts of styrene-butadiene latexes; 2 parts of blue microcapsules colour formers; 0.02 part of fluorescer; Red temperature becomes 4 parts of materials, 40 DEG C of discoloring temperatures; 26 parts, water;
