Abstract
The invention relates to an anti-counterfeiting mark, in particular to a manufacturing method of a shape memory anti-counterfeiting mark with permanent memory information. The manufacturing method of the shape memory anti-counterfeiting mark with the permanent memory information comprises preparation of a high-molecular polymer material. The high-molecular polymer material is prepared by the following components, by weight, 100 parts of polylactic acid, 0.1-1 part of polycaprolactone, 0.1-1 part of deoxyribonucleic acid (DNA) printing ink, 0.01-0.2 part of antioxygen and 0.1-0.3 part of inorganic filler. The manufacturing method of the shape memory anti-counterfeiting mark is simple and easy to operate and easy to achieve. The anti-counterfeiting mark can distinguish the true from the false in duplex mode, can protect consumer benefit, guarantees manufacturer benefit and product reputation, and is particularly suitable for being applied to high-end products. In addition, polylactic acid and polycaprolactone are both biodegradable. The anti-counterfeiting mark is an environment-friendly anti-counterfeiting mark.
Description
Technical field
The present invention relates to a kind of anti-counterfeiting mark, be specifically related to a kind of method for making with the shape memory anti-counterfeiting label of permanent memory information.
Background technology
Current anti-counterfeiting mark is varied, in the majority with paper anti-counterfeiting mark, laser class anti-counterfeiting mark, adopts the mode of Help by Phone or the false proof discriminating of ink to exist simultaneously.The application of anti-counterfeiting mark, not only protects the product of businessman, returns the discriminating of consumer to authenticity of products and brings conveniently.
Along with the development of economic society, the use with the anti-counterfeiting mark of shape memory function is more and more extensive.Shape memory anti-counterfeiting label is generally utilize the memory function of high molecular polymer to realize.This type of anti-counterfeiting mark is put into the hot water of 100 degree or is roasted anti-counterfeiting mark with lighter, and anti-counterfeiting mark can be formed with the concave-convex sense of word or LOGO, and this kind of mode is differentiated for consumers, simple and imitation property difficulty is high.But this type of anti-counterfeiting mark is only suitable for being applied in the mill run of daily life, for some high-end products, after product is destroyed, more particularly still need the product carrying out collecting evidence, just there is not any advantage in these common anti-counterfeiting marks, do not reach some discriminating requirements in particular cases at all.
Therefore the shape memory function anti-counterfeiting mark with multiple discriminating means of development functionality is the direction of anti-counterfeiting mark industry.
Summary of the invention
The object of this invention is to provide a kind of method for making with the shape memory anti-counterfeiting label of permanent memory information, the shape memory anti-counterfeiting label produced can not only be differentiated the true and false of product, even if also can carry out the discriminating of authenticity of products when anti-counterfeiting mark damages or destroy.
The method for making with the shape memory anti-counterfeiting label of permanent memory information of the present invention, comprises the preparation of macromolecule polymer material, and macromolecule polymer material is prepared from by the component of following mass fraction:
Described antioxidant is 1010 or 168.
Described inorganic filler is nano titanium oxide.
Described method for making, comprise the following steps: after each component of formula ratio being mixed in an extruder, be extruded as flaky material, flaky material is put in heater and carries out heating generation deformation, then press pattern or word on flaky material, obtain the false proof base material of shape memory with permanent memory information, base material is obtained after printing, gluing, cross cutting the shape memory anti-counterfeiting label with permanent memory information.The structure of this anti-counterfeiting mark is rubberised layer, false proof substrate layer, printed layers from bottom to up successively.
The extrusion temperature 180-190 degree of described extruder, screw speed 300-400r/min.
In the present invention:
PLA and DNA ink are carried out being mixed and made into novel material instead of printing DNA ink on original macromolecular material, reason is as follows:
One is: the aesthetics of anti-counterfeiting mark requires more and more higher at present, client can require exquisite printing, and current DNA ink printing must through drying this step, but macromolecular material is when drying, if temperature is too high, just can cause the damage of base material, and this kind of base material has nonreversibility, just mean breakage once damage.Equally, the anti-counterfeiting mark of this type of base material more cannot carry out stamp and upper covering ink.
Two are: because DNA ink belongs to water color ink, it is without adhesion on macromolecular material, so DNA ink can only be mixed with macromolecular material, doing the term of validity not only making DNA ink deposit like this increases, and under the effect of polycaprolactone, well merge.Polycaprolactone, as the compatilizer of PLA and DNA ink, has played great effect in the present invention.
In addition, make the adding of antioxidant the anti-counterfeiting mark holding time of the present invention more permanent, the existence of inorganic filler make PLA, polycaprolactone, DNA ink three mixing more even, add the mobility of polylactic resin, improve processing characteristics.
Beneficial effect of the present invention is as follows:
Anti-counterfeiting mark of the present invention is not only provided with the simple identification method required for client, also has the hiding identification method required for manufacturer simultaneously, namely has dual function of discerning the false from the genuine, and one is have shape identification function; Two is the functions still can carrying out after having destruction differentiating.Can not only the interests of Protection of consumer, and ensure that the interests of manufacturer and the reputation of product, be particularly suitable for applying on high-end product.PLA and polycaprolactone are all biodegradable in addition, and therefore, anti-counterfeiting mark of the present invention is environment-friendly type anti-counterfeiting mark.
Embodiment
