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: Including an anti-counterfeiting wine bottle cap with a single shape memory function based on polyurethane. The anti-counterfeiting target is a wine bottle, and the anti-counterfeiting components are figure 1 The wine bottle cap shown. The shape of the cap when used to seal the bottle mouth is like figure 1 As shown in (a), the diameter is 3 cm and the 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, such as figure 1 As shown in (b), the diameter is 3.9 cm and the height is 1.8 cm, which is the initial state after the shape is restored. Based on this, the wine was judged to be genuine.

Embodiment 2

[0026] Embodiment 2: Including the preparation of anti-counterfeiting perfume bottle caps with two-way shape memory function using epoxy resin as a matrix. The anti-counterfeiting target is a perfume bottle, and the anti-counterfeiting component is figure 2 Perfume bottle cap shown. The shape of the bottle cap used to seal the bottle mouth is like figure 2 As shown in (a), the diameter is 2 cm and the 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, such as figure 2 As shown in (b), the diameter is 2.7 cm and the height is 1.6 cm. This is the state after the first shape recovery. The cap can be separated from the perfume bottle; after heating it with boiling water, the cap shrinks, such as figure 2 As shown in (c), the diameter is 2 cm and the height is 1.6 cm. At this time, it is the state after the second shape recovery, and the bottle cap can be reconnected with the bottle body. Th...

Embodiment 3

[0027] Example three: such as image 3 As shown, the anti-counterfeiting instruction process of an electronic device main board with a single-time shape memory function anti-counterfeiting mark. The board body with anti-counterfeiting mark is an anti-counterfeiting part, such as image 3 (A) as shown; when the authenticity needs to be verified, such as image 3 As shown in (b), heating the letter "AD" on the main board, "AD" disappears, and the letter "BC" appears. According to 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 present invention relates to anti-counterfeiting technology for commodities or other items, specifically an item with a shape memory anti-counterfeiting component and an anti-counterfeiting method for the item. Background technique [0002] In today's commodity economy era, the development of enterprises faces increasingly fierce business competition. Protecting your products from being imitated through advanced anti-counterfeiting means is an issue that companies must pay attention to for their long-term development. Currently commonly used anti-counterfeiting technologies (such as digital anti-counterfeiting technology, laser anti-counterfeiting technology, barcodes and patterns, etc.) have gradually been cracked due to their core technologies. Research and development of new anti-counterfeiting technologies have become an urgent need. [0003] Shape memory polymer is a new type of functional material characterized by its significant shape recov...
