Description
Technical field
The present invention relates to the anti-counterfeiting technology of commodity or other article, specifically a kind of have the article of shape memory security element and a method for anti-counterfeit of article.
Background technology
At commodity economic times now, the development of enterprise is in the face of day by day fierce commercial competition.Protect the commodity of oneself not imitated by advanced person's false proof means, be long-term development of enterprise the essential problem of paying attention to.The anti-counterfeiting technology (as digital anti-counterfeiting technology, laser antifalsification technology, bar code and pattern etc.) of commonly using at present, because its core technology is cracked gradually, researching and developing new anti-counterfeiting technology becomes current exigence.
Shape-memory polymer is a kind of novel functional material, and its characteristic is for having significant shape restore funcitons (SME), namely can the perception environmental evolution, and make response in the mode that pattern changes (restPosing).Wherein, temperature variation is the most general a kind of energisation mode of SME.At present, the multinomial patent that the existing SME that utilizes heat to drive polymkeric substance carries out false proof indication, but significant limitation is still arranged and have many deficiencies.
Patent CN101877196B has proposed a kind of method for making of shape memory anti-counterfeiting label.Related anti-counterfeiting mark only limits to sheet material (flat sheet or the sheet material of relief pattern is arranged), and material must carry out cross-linking radiation and processes.The anti-counterfeiting mark form that the method provides is single, and needs expensive irradiation apparatus, and cost is high, and application is extremely restricted.
Patent CN101916528B has proposed a kind of method for making of shape memory anti-counterfeiting label.But the method is only applicable to have after need adopting peroxide crosslinking technique or one-step method silanes crosslinked PROCESS FOR TREATMENT the polymeric material of SME, and related anti-counterfeiting mark also only limits to sheet material (flat sheet or the sheet material of relief pattern is arranged).The crosslinking process that the method is used is comparatively complicated and restricted strong, is not suitable for widespread use.
Patent CN102024379A has proposed a kind of method for making of shape memory anti-counterfeiting label.The pre-treatment that shape-memory polymer is done is defined in and is carrying out more than glass transition temperature, below fusing point, and such requirement is to a lot of shape-memory polymers and inapplicable.And related anti-counterfeiting mark also only limits to sheet material (flat sheet or the sheet material of relief pattern is arranged).
Patent CN201745882U, CN201838256U have discussed respectively a kind of anti-forge wine bottle cap and Anti-counterfeiting tag.Its main method is shape-memory polymer to be inlayed or sticked in wine bottle cover part or drop part to carry out false proof indication.The false proof mode of this kind is easy to be copied or divert.
Also there is a common limitation in above patent except above-mentioned variety of issue: only can change to carry out false proof indication by the disposable pattern in heating process by shape-memory polymer.Its technical difficulty is limited, easily is imitated or diverts, thereby antiforge function was lost efficacy.
Therefore, be necessary further to improve the existing false proof indicating means that drives SME based on heat, produce and have more senior antiforge function, the sign product that is difficult to crack.
Summary of the invention
Technical matters to be solved by this invention is, a kind of imitation difficulty that can improve article is provided, improves false proof indication reliability, and the easy to operate article with shape memory security element and the method for anti-counterfeit of article.
Article with shape memory security element of the present invention include false proof object and the security element that is associated, the matrix of described security element is the thermal shape memory polymeric material, is provided with one or more predeformation corresponding with recovery temperature separately on the matrix of security element; Judge the true and false of article by the shape recovery situation of security element under different recovery temperature conditions.Described false proof object can be to need false proof article itself (for example certain commodity itself) or its packing material.
The shape of at least one predeformation on described security element makes security element to be connected with false proof object, and security element and false proof object are broken away from or the part disengaging.On this scheme basis, can also have a predeformation when its recovery temperature, security element is out of shape again on described security element, and the shape after again being out of shape can be connected the security element that breaks away from or partly break away from false proof object again with false proof object.
The method for anti-counterfeit of article of the present invention is: will need false proof article (comprising article itself or its packing material) as false proof object, the security element that is associated with anti-false proof object is set, the matrix of security element is the thermal shape memory polymeric material, and one or more predeformation corresponding with recovery temperature separately are set on the matrix of security element.Judge the true and false of article by the shape recovery situation of security element under different recovery temperature conditions.
Described one or more predeformation can be in the process of one or many heating, the predeformation of implementing under the glass transition of this material or the different temperatures more than the melting transition initial temperature.
When the matrix material of security element had one or more glass transitions or melting transition characteristic, described one or more predeformation can be the predeformation of implementing on one or more glass transitions or melting transition initial temperature.
Make the shape that has a predeformation on security element at least that security element is connected with false proof object, and when this predeformation is recovered, security element and false proof object are partly or entirely broken away from.On this basis, also have at least a predeformation when its recovery temperature, security element to be out of shape again on security element, and the shape after again being out of shape can be connected the security element that breaks away from or partly break away from false proof object again with false proof object.
The present invention compared with prior art has following advantageous effect:
1, the present invention can change to carry out false proof indication by the one or many pattern of shape-memory polymer, and the imitation difficulty is large, and false proof rank is high.
2, the present invention can be as required, makes the anti-counterfeiting mark of multi-form (as the part of the packing of product, or the part of product self), difformity and size, different predeformation modes and realize, copys difficulty thereby further improve.
3, thermal shape memory polymkeric substance used in the present invention can be selected from existing commercial polymkeric substance, thereby can significantly reduce costs.
