Abstract
The invention discloses an aqueous interval chromophoric false-proof printing ink. The aqueous interval chromophoric false-proof printing ink is mainly prepared from the following raw materials: 45 to 51 parts of an acrylic emulsion, 26 to 35 parts of water, 18 to 25 parts of an interval chromophoric capsule pigment and 0.2 to 0.8 part of 2,4,7,9-tetramethyl-5-decyne-4,7-diol. The invention further discloses a preparation method for the aqueous interval chromophoric false-proof printing ink. The aqueous interval chromophoric false-proof printing ink provided by the invention develops a color in a range of 35 to 45 DEG C, is colorless at a temperature lower than 35 DEG C or higher than 45 DEG C and overcomes the problem of no such interval chromophoric false-proof printing ink in the prior art.
Description
Technical field
The present invention relates to anti-forgery ink technical field, particularly the interval color development anti-forgery ink of a kind of water-based.
Background technology
Along with the development of market economy, anti-counterfeiting technology more and more comes into one's own, and it can protect brand names, protection market, protection consumers in general legitimate rights and interests.Anti-forgery ink is a kind of important anti-counterfeiting technology, and anti-forgery ink refers to the material adding in ink raw materials and the change of properties such as color, soft durometer can occur under certain condition, and with the special printing inks of other auxiliary agent Homogeneous phase mixing.Be printed on by described anti-forgery ink in ticket, product brand and packaging, namely human consumer obviously can tell the true and false of product by estimating or touching.Anti-forgery ink is simple to operate, cost is low, good concealment, bright in luster, inspection convenient (even hand temperature can change color), circulation ratio are strong.
There is multiple anti-forgery ink on the market at present, but not yet occur only color development in certain temperature interval, and be outward colourless interval color development anti-forgery ink in temperature range.
Summary of the invention
The object of the invention is to solve the problem, providing a kind of water-based interval color development anti-forgery ink.
Technical scheme of the present invention is as follows:
The interval color development anti-forgery ink of a kind of water-based, the raw material primarily of following weight part is prepared from:
ACRYLIC EMULSION 45-51 part,
Water 26-35 part,
Interval color development capsule pigment 18-25 part,
2,4,7,9 tetramethyl--5-decine-4,7-glycol 0.2-0.8 parts.
Wherein, ACRYLIC EMULSION and water are all the bases of water color ink system, and 2,4,7,9 tetramethyl--5-decine-4,7-glycol are auxiliary agents, have levelling and froth breaking effect concurrently.
In a preferred implementation of the present invention, the interval color development anti-forgery ink of above-mentioned water-based is prepared from primarily of the raw material of following weight part:
ACRYLIC EMULSION 50 parts,
30 parts, water,
Interval color development capsule pigment 20 parts,
2,4,7,9 tetramethyl--5-decine-4,7-glycol 0.3 part.
The ink that this screening formulation obtains with above-mentioned formula in a big way relatively has better properties, and transitivity is good, clear patterns, and color changeable effect is good.
Preferred above, the pH value of described ACRYLIC EMULSION is 6-7, and the cohesion limit is 7-9, and viscosity is 13-15 second, and acid number is 30 ± 5.Select this kind of ACRYLIC EMULSION that the ink of gained can be made more to stablize and have better printability, color developing effect is also better.
Wherein, in certain embodiments of the present invention, described interval color development capsule pigment can be red, blueness, black or purple.
The preparation method of ink of the present invention can adopt current photogravure ink production technique, and a kind of preparation method wherein specifically can comprise the following steps:
(1). by ACRYLIC EMULSION, water, 2,4,7,9 tetramethyl--5-decine-4,7-glycol mix, and then add interval color development capsule pigment by Subtraction method, stir until be uniformly dispersed;
(2). roller pressure before and after adjustment three-roller, make its not between destruction region the microcapsule of color development capsule pigment be limited, after ink being poured into three-roller in black groove, disperseed further by the powder of three-roller by state of aggregation, ink is entered in the inking bucket with reserved solvent by preliminary roller disc; With reserved solvent, the residual ink in agitation vat is rinsed wash clean after terminating, to be got back to after three-roller in central roll ink groove, allow the residual ink on roller take front disc further to, then rinse to wash to get back to and connect in black bucket;
(3). carry out next step and stir, speed control, at 300-350 rev/min, stirs after 15 minutes, detects (adjustment, detection), qualified rear metering packing by normal quality.
Compared with prior art, beneficial effect of the present invention is as follows:
The first, the present invention, by special formulating of recipe, provides a kind of interval color development anti-forgery ink, fills up at present the blank of not this kind of ink on the market;
The second, interval color development anti-forgery ink of the present invention is water-based, has obvious safety and environment-friendly advantage, does not have the shortcoming that organic solvent type ink exists.
Certainly, implement arbitrary product of the present invention might not need to reach above-described all advantages simultaneously.
