Abstract
A method for manufacturing a titanium-nickel alloy anti-counterfeiting label carried with implicit information is that pit patterns are pressed on the surface of a titanium-nickel shape memory alloy material having the shape memory effect through a male die with anti-counterfeiting patterns, then the surface of the titanium-nickel shape memory alloy material provided with the pit patterns is subjected to mechanical polishing till pits on the titanium-nickel alloy surface disappear. Therefore, the pattern information implied in the material cannot be seen through naked eyes or microscopes, X-ray and other physical and chemical means by viewing from the appearance, and the anti-counterfeiting purpose is achieved. A titanium-nickel alloy anti-counterfeiting label sheet manufactured by means of the method can display the implicit information when being heated to be higher than Af, an anti-counterfeiting identification function is achieved, and the method is simple and reasonable, and the detection operation is convenient.
Description
Technical field
The present invention relates to the anti-counterfeiting mark of the industries such as automobile and equipment, be specifically related to a kind of preparation method of the Ti-Ni alloy anti-counterfeiting mark with implicit information.
Background technology
Counterfeit and shoddy goods become the significant obstacle of social development just day by day, have had a strong impact on socioeconomic order, day by day become global problem, serious contusion research and development new technology personnel's enthusiasm, novelty has been formed to serious threat.The fraud of the fraud of commodity, especially medicine and food service industry, directly endangers people's life health, even life security.
At present, the multinomial patent that the existing SME that utilizes heat to drive carries out false proof indication.Patent CN101916528B and CN102024379A have proposed a kind of preparation method of shape memory anti-counterfeiting label.But the method is only applicable to have the polymeric material of SME, processing technology used need adopt peroxide crosslinking technique or one-step method silanes crosslinked PROCESS FOR TREATMENT, or pre-treatment is limited to, and glass transition temperature is above, fusing point carries out below.The crosslinking process that above-mentioned patent is used is comparatively complicated and restricted strong, is not suitable for extensive use, and the pre-treatment that shape-memory polymer is done to be limited to requirement below glass transition temperature inapplicable to most of shape-memory polymer.Patent CN103093690 proposes to have the article of shape memory security element and the method for anti-counterfeit of article, shape memory security element is arranged to one or more predeformation corresponding with recovery temperature separately, by the shape recovery situation of security element under different recovery temperature conditions, judge the true and false of article.Related anti-counterfeiting mark control of material predeformation and the technique of temperature relation are comparatively complicated and restricted strong, are not suitable for extensive use.
Ti-Ni marmem is as a kind of novel functional material, it is characterized by and there is significant shape memory restore funcitons (SME), variation (stress and temperature) that can sensing external environment, and make response in the mode of change of shape (restPosing).Wherein, variations in temperature is the most general a kind of energisation mode of SME.Patent CN1146033A has proposed anti-fake marmem mark and preparation method.But the related anti-counterfeiting mark of the method only limits to shape-memory alloy wire, and suitably soak training managing of material.The anti-counterfeiting mark that the method provides is more single, and application is extremely restricted.Yang-Tse[Understanding indentation-induced two-way shape memory effect, Journal of Materials Research, 2007,22 (10): 2851-2855] in, show can make TiNi alloy show double-pass memory effect by the cooling of repeatedly heating.Xueling Fei[Surface form memory in NiTi shape memory alloys by laser shock indentation, Journal of Materials Research, 2012,47:2088-2094] by test, show that laser pressing also can bring out double-pass memory effect on marmem surface.But above-mentioned research all has a common feature: Ti-Ni marmem must carry out low temperature (20 ℃) before pit in compacting to be processed take Ti-Ni marmem initial phase in guaranteeing experimentation as martensitic phase, has limited its application.
Therefore, be necessary further to improve the existing false proof preparation method who drives SME based on heat.This characteristic of SME of utilizing Ti-Ni marmem itself to have, produces and has better anti-fake effect and easy to operate sign product.
Summary of the invention
For the defect of prior art, the object of this invention is to provide a kind of preparation method of the Ti-Ni alloy anti-counterfeiting mark with implicit information; By the present invention, can make in enormous quantities the Ti-Ni alloy anti-counterfeiting mark with concealed anti-false, the memory characteristic of marmem is imported to commodity false proof mark, make Ti-Ni marmem anti-counterfeiting mark under heating condition, give full play to the memory characteristic of alloy, recover the reverse form of original pressing process, thereby reach good anti-fake effect, and easy to operate.
