Abstract
The invention discloses a method for manufacturing a shape memory anti-counterfeiting mark, which is characterized by comprising the following steps of: manufacturing a polymer material having a shape memory function into boards of which the surfaces are provided with uneven patterns, wherein appropriate distances should be reserved among the patterns on the board to ensure that the patterns are not superposed with one another in the subsequent calendering process; irradiating and cross-linking the boards; heating the boards of which the surfaces are provided with the uneven patterns after irradiating and cross-linking, and calendering the boards into thin films by using a three-roll calender to ensure that the boards of which the surfaces are provided with the uneven patterns become the films with smooth surfaces through the calendering; and according to the calendering degree of the patterns, cutting the films into a plurality of small pieces only containing one pattern. The method has the advantages of simple manufacturing process, convenient deformation detection and low cost; and by using a characteristic that a high molecular polymer having a shape memory effect is used for shaping the shape memory anti-counterfeiting mark, the method can realize anti-counterfeiting on a wine bottle cap.
Description
Technical field
The present invention relates to the method for making of a kind of method for making, particularly a kind of shape memory anti-counterfeiting label.
Background technology
Disclose name in the Chinese patent (patent No. 200410051383.1) and be called " a kind of method for anti-counterfeit of the packing of product ", it provides a kind of new method for anti-counterfeit.But this method is not put down in writing the concrete manufacture craft of shape memory anti-counterfeiting label.
Summary of the invention
The object of the present invention is to provide a kind of manufacturing process simple, convenient deformation detection, the method for making of lower-cost shape memory anti-counterfeiting label.
The object of the invention can reach through following measure: a kind of method for making of shape memory anti-counterfeiting label; It is characterized in that: the macromolecular material that will possess shape memory function is processed the sheet material that the surface has uneven pattern; Should have suitable distance between the pattern on the sheet material,, guarantee that pattern is not overlapping each other so that in follow-up calender line; And above-mentioned sheet material carried out cross-linking radiation; Roll into film the sheet material heating that has uneven pattern through the surface of cross-linking radiation and with tri-roll press machine again, through such calendering, the sheet material that the surface has a uneven pattern has just become the film of surfacing; The degree of being rolled according to pattern again is cut into several small pieces that are implied with a pattern to film and gets final product.
The object of the invention can also reach through following measure: the macromolecular material that possesses shape memory function can be extruded unit with sheet material and squeeze out the sheet material that the surface has uneven pattern with the three-roller calendar with embossing cylinder.Can the macromolecular material that possess shape memory function be extruded into flat sheet, sheet material is cut into required specification by the size of hot pressing die, then sheet material is put into hot pressing die, at the uneven pattern of surface heat extrusion of sheet material.Described uneven pattern also can be one group of literal and a kind of shape.Said thickness with sheet material of uneven pattern is 0.2-2.0mm.The thickness of said flat sheet is 0.2-2.0mm.The thickness of said film is 0.1-0.3mm.
The present invention compares prior art and has following advantage: manufacturing process is simple, convenient deformation detection, and cost is lower; Utilization has the high molecular polymer of SME this characteristic of memory to its figuration, can be implemented in false proof that bottle covers.
Embodiment
Embodiment one
Utilize single screw rod sheet material to extrude unit; This sheet material is extruded the roller surface of unit and has been set a plurality of identical patterns or organized identical literal more; Pattern that these are identical or literal have certain distance each other, and (size of this distance depends on the sheet material of extruding in the back by the degree of calendering attenuation, and when the sheet metal thickness of extruding one timing, it is thin more that sheet material is rolled; Then identical pattern or literal distance each other is big more), pattern that these are identical or literal also are protrusions or recessed.Extrude the macromolecular material that unit will possess shape-memory properties with such sheet material; Like ENB, using trans-polyisoprene, polyurethane, SB etc.; Be extruded into the surface and have the pattern corresponding with roller or the sheet material of literal, sheet metal thickness is 0.2-2mm (with 1.5mm for well).These sheet materials are carried out cross-linking radiation,, be pressed into the sheet material of heating with three-roller calendar the film of 0.1--0.3mm (being) then with 0.3mm again the heating of the sheet material of above-mentioned cross-linking radiation; With film printing, be cut into small pieces to film again, each small pieces film has all implied a pattern or one group of literal; Be attached to these small pieces films on the commodity; When needs are checked the true and false of commodity, put the small pieces film in the boiling water into, then these small pieces films will dwindle; Show pattern or literal on the roller simultaneously, play false proof effect.
Embodiment two
Also can the macromolecular material that possess shape memory function be extruded into flat sheet; The thickness of flat sheet for well, is cut into required specification with sheet material by the size of hot pressing die, as 0.5 * 0.5 meter with 0.2-2.0mm; Perhaps 0.3 * 0.2 meter etc.; Then sheet material is put into hot pressing die, extrude uneven pattern (or one group of literal and a kind of shape) at the surface heat of sheet material, the sheet material that the surface that mold pressing is formed has uneven pattern (or a group literal and shape) carries out cross-linking radiation; Roll into film the sheet material heating that has uneven pattern (or a group literal with a kind of shape) through the surface of cross-linking radiation and with tri-roll press machine again; Film thickness with 0.1-0.3mm for well, through such calendering, thin slice that the surface has a uneven pattern (or one group of literal and a kind of shape) just become area become big, the film of surfacing; The degree of being rolled according to pattern (or one group of literal and a kind of shape) again; Be cut into several to film and be implied with a pattern (or one group of literal and a kind of shape) small pieces, just form shape memory anti-counterfeiting label, after putting into boiling water to shape memory anti-counterfeiting label; The area of this shape memory anti-counterfeiting label will also can be become uneven pattern (or one group of literal and a kind of shape) simultaneously by smooth film from large to small.
