Abstract

The making method of anti-fake trade mark or mark. After passing through the imaging mould, the high-energy heavy ions or fission fragments are irradiated on the transparent plastic film, and after irradiation, a milky white pattern with bright contrast can be formed on the film. The pattern can be used as a trademark or a commodity mark. The irradiated area of the film has a plurality of micropores, so that the film can be breathable and permeable, and consumers can easily identify the authenticity of the film. The trademark or mark thus produced is not easy to be imitated and has low production cost.

Description

The manufacture method of anti-false trademark or sign

The present invention relates to the manufacture method of anti-false trademark or sign, particularly relate to the method for utilizing heavy ion or the imaging of fission fragment irradiation to make anti-false trademark or sign.

In current commodity market, fake products often appears, and give consumer, manufacturer so that cause heavy losses to country, the anti-vacation of therefore cracking down on counterfeit goods becomes pressing problem in the current commodity market.Reach the anti-vacation of cracking down on counterfeit goods effectively, at first will solve the anti-pseudo problem of trade mark or product marking.Present common anti-false trademark or sign, some is easily by imitated, and some is difficult for being differentiated by the consumer, though and some difficult copying is difficult to popularization owing to cost is too high.

The objective of the invention is to provide a kind of both being not easy easily to be differentiated again simultaneously by the consumer by imitated, and the manufacture method of cheap anti-false trademark or sign.

The inventor has carried out all research at the shortcoming of existing anti-false trademark and sign existence, found that, utilize heavy ion (referring to the ion of quality) or fission fragment to come the transparent plastic sheeting of irradiation greater than the α particle, handle this film with NaOH solution then, can make radiation exposed zone become opaque or translucent milky, and can air-and water-permeable.If the mould with hollow out floral designs is installed in the passage of heavy ion or fission fragment irradiation in advance, make heavy ion or fission fragment to pass through, so just can on plastic sheeting, form corresponding milky and floral designs that can air-and water-permeable from the openwork part of this mould.Because therefore this pattern air-and water-permeable is made trade mark with it and can be easy to be discerned by the consumer.And because generation heavy ion or fission fragment need use main equipments such as accelerator or atomic pile, therefore trade mark or the sign with this method manufacturing is difficult for being copied.Also be easy to find the source even someone copys, count seldom because have the unit of accelerator or atomic pile at home.In addition, manufacturing mark in this way, cost is lower than general anti-false trademark, is therefore easily accepted by producer.Owing to found this manufacturing anti-false trademark or denotation approach, so far just finished the present invention.

The principle of the inventive method is to utilize high-energy heavy ion or the fission fragment of energy more than 80MeV to come the transparent plastic sheeting of irradiation, heavy ion or fission fragment can make the radiation exposed wound that is partially damaged on the film, after damaged portion being eroded with Na0H solution, just on plastic sheeting, form some irregular small ducts, its diameter is about 0.1 μ m-12 μ m, the tube wall in these ducts reflects by different directions incident light and reflects, therefore play a kind of scattered beam, most of light can not be seen through, so on transparent plastic film, formed milky pattern with required form.

The inventor has proposed two kinds of methods that are used to make anti-false trademark or sign altogether on the basis of many experiments.Method 1 wherein is to utilize heavy ion as the irradiation energy, and method 2 is to utilize fission fragment as the irradiation energy.

Explain the present invention particularly below with reference to accompanying drawing.

Fig. 1 utilizes the heavy ion imaging method to make the schematic flow diagram of anti-false trademark or sign;

Fig. 2 utilizes the fission fragment imaging method to make the schematic flow diagram of anti-false trademark or sign.

Method 1 of the present invention is to utilize the heavy ion imaging method to make anti-false trademark Or sign, it is characterized in that utilizing thickness is 5-30 μ m, be preferably 8-The transparent plastic film of 20 μ m is raw material, utilizes the heavy ion generator to produce The heavy ion of giving birth to is the irradiation energy, with heavy ion avcceleration heavy ion is accelerated to Its energy reaches more than the 80MeV, is as the criterion can penetrate plastic sheeting, The imaging mould is installed on the passage of heavy ion, makes the HIB spoke after the imaging Impinge upon on the plastic sheeting, exposure time is 0.5-2 seconds, is preferably 0.8-1 second, with NaOH solution film is carried out the etching video picture then and process 1 More than hour, image is as the criterion can show clearly after the drying, and last water is clear Wash and be dried.

The energy of used heavy ion does not have strict restriction in this method 1, But generally should more than 80MeV, be preferably in more than the 130MeV, This will depend on kind and the thickness of used plastic sheeting, the energy of heavy ion with Can penetrate radiation exposed film is as the criterion. The thickness of film is with 5-30 μ m Be advisable, be preferably 8-20 μ m, if thickness then exists less than 5 μ m Trade mark is easy to film is torn when commodity take off, does not so just reach mirror The purpose of the other true and false. If film is thicker than 30 μ m, then require the heavy ion tool There is higher energy just can penetrate film, so economically inadvisable. But In the necessary situation, also can make film thicker. Time during the irradiation film As long as the not strict restriction of length is can imaging on film, for thinner Film, only need 0.5 second or 1 second can imaging, but the time be longer also not Affect quality. In etching step, not tight to the concentration of NaOH solution The requirement of lattice, when just NaOH solution was rarer, etching period is corresponding will be grown A bit. In the ordinary course of things, the NaOH solution concentration is with 10-50 weights Amount % (take solution weight as benchmark) is advisable, and is preferably 20-40 weights Amount %. The not strict restriction of etching period can clearly show with image Be as the criterion.

Method 2 of the present invention is to utilize the fission fragment imaging method to make anti-false trademark or sign, it is characterized in that utilizing thickness is 5-30 μ m, the transparent plastic film that is preferably 8-20 μ m is raw material, the neutron that utilizes atomic pile to produce is primary energy, makes the neutron beam bombardment²³⁵The U target so that its Emit fission fragment, make these fission fragments by the imaging mould after irradiation moulding On the material film, exposure time is 10-20 minutes, then with NaOH solution film is carried out the etching video picture and processes more than 1 hour, can show after the drying Go out clearly that image is as the criterion, last water cleans also and is dried.

In method 2, because from²³⁵The energy of the fission fragment that the U target is emitted Amount has on average reached more than the 80MeV, does not therefore usually need further to carry High its energy. But because the particle density of fission fragment is less than the weight in the method 1 The ion particle density, so imaging time will grow, but when irradiation, can With²³⁵Around the U target a lot of sheet films are set, have so just remedied it The deficiency that the imaging time is long. In method 2 to film thickness, NaOH concentration and to the grasp of other conditions except exposure time all with above-mentioned Method 1 identical.

With trade mark or sign that the inventive method is made, its antifalse effect is obviously excellent In common anti-false trademark. The consumer only needs trade mark or sign are got from commodity Get off, with being applied in milky zone behind the finger-dipping water, see whether it is permeable, Or the smog that produces during with smoking blows and sprays, and sees whether it ventilative, every can not be saturating Water, ventilative person must for counterfeit trademark undoubtedly. In addition, utilize method of the present invention Make anti-false trademark or sign, with low cost, high productivity is easy to automation. Having is the trade mark made from the inventive method again, copys difficulty, even there is the people imitative Make, also find easily the imitator. So method of the present invention and prior art Method is compared, and has outstanding substantive distinguishing features and significant progressive.

Enumerate preferred embodiment of the present invention below, but the present invention is not subjected to the restriction of these embodiment.
