Problems solved by technology

[0008] In addition to the above-mentioned various problems, the above patents also have a common limitation: anti-counterfeiting indication can only be provided through a one-time shape change of the shape memory polymer during heating
Its technical difficulty is limited, and it is easy to be imitated or misappropriated, thus making the anti-counterfeiting function invalid

Embodiment 1

[0025] Embodiment 1: It includes an anti-counterfeiting wine bottle cap with polyurethane as the matrix and a single shape memory function. The anti-counterfeiting target is a wine bottle, and the anti-counterfeiting components are figure 1 Wine bottle caps shown. The shape of the bottle cap when it is used to seal the bottle mouth is as follows figure 1 As shown in (a), its diameter is 3 cm, and its height is 1.8 cm. At this time, it is in a pre-deformed state; when it is heated to about 60 ° C, the bottle cap becomes larger, as shown in figure 1 As shown in (b), its diameter is 3.9 cm, and its height is 1.8 cm. At this time, it is the initial state after shape recovery. Based on this, it is determined that the wine is genuine.

Embodiment 2

[0026] Embodiment 2: including using epoxy resin as a matrix to prepare an anti-counterfeiting perfume bottle cap with two-way shape memory function. The anti-counterfeiting target is a perfume bottle, and the anti-counterfeiting parts are figure 2 Perfume bottle cap shown. The shape of the bottle cap used to seal the mouth of the bottle is as figure 2 As shown in (a), its diameter is 2 cm, and its height is 1.6 cm. At this time, it is in a pre-deformed state; it is heated with warm water (about 60°C), and the bottle cap becomes larger, as shown in figure 2 As shown in (b), its diameter is 2.7 cm, and its height is 1.6 cm. At this time, it is the state after the first shape recovery, and the bottle cap can be separated from the perfume bottle; after heating it with boiling water, the bottle cap shrinks, as shown in figure 2 As shown in (c), its diameter is 2 cm, and its height is 1.6 cm. At this time, it is the state after the second shape recovery, and the bottle cap ca...

Embodiment 3

[0027] Embodiment three: as image 3 As shown, the anti-counterfeiting indication process of the main board of the electronic device with the anti-counterfeiting mark of the single shape memory function. Its plate body with anti-counterfeiting marks is an anti-counterfeiting component, such as image 3 As shown in (a); when it is necessary to verify the authenticity, such as image 3 As shown in (b), the letters "A D" on the heating board, "A D" disappear, and the letters "BC" appear. Based on this change, the authenticity of the electronic device is identified.

Abstract

The invention relates to commodities and an anti-counterfeiting technology for other objects, in particular to an object with a shape memory anti-counterfeiting component and an anti-counterfeiting method for the object. The object with the shape memory anti-counterfeiting component comprises an anti-counterfeiting target object and the anti-counterfeiting component which are correlated with each other; a base body of the anti-counterfeiting component is made of a thermally induced shape memory polymer material; the base body of the anti-counterfeiting component is provided with one or more predeformations corresponding to respective recovery temperature; and the authenticity of the object is judged according to the shape recovery conditions of the anti-counterfeiting component at different recovery temperature. By the method, the counterfeiting difficulty of the object can be increased, and the anti-counterfeiting indication reliability can be improved; and the method is convenient to operate.

Description

technical field [0001] The invention relates to an anti-counterfeiting technology for commodities or other articles, in particular to an article with a shape memory anti-counterfeiting component and an anti-counterfeiting method for the article. Background technique [0002] In today's commodity economy era, the development of enterprises faces increasingly fierce commercial competition. Protecting one's own products from imitation through advanced anti-counterfeiting means is a topic that must be paid attention to by the long-term development of enterprises. Currently commonly used anti-counterfeiting technologies (such as digital anti-counterfeiting technology, laser anti-counterfeiting technology, bar codes and patterns, etc.) have gradually been cracked because of their core technologies, and research and development of new anti-counterfeiting technologies has become an urgent need. [0003] Shape memory polymer is a new type of functional material, which is characteriz...
