Description

Technical Field

[0001] This invention relates to a novel anti-counterfeiting transfer material and its preparation method, belonging to the field of holographic anti-counterfeiting technology. This invention not only achieves the reuse of polyester film and separation layer in the preparation process of the anti-counterfeiting transfer material, but also makes the preparation process more efficient and environmentally friendly, while the resulting product has a stunning holographic anti-counterfeiting effect. Background Technology

[0002] Anti-counterfeiting transfer materials are heat transfer materials composed of multiple layers of coatings with different functions. Due to their holographic anti-counterfeiting graphic effects and ease of use, they have been widely used in various anti-counterfeiting labels, daily chemical consumer goods, and gift boxes in recent years, and are gradually expanding into high-end labeling fields such as consumer electronics and chips. However, due to current technological limitations, the release layer of traditional anti-counterfeiting transfer materials separates from the polyester film after heat stamping, making it impossible to reuse the polyester film and release layer during the preparation process. Furthermore, in the traditional anti-counterfeiting transfer material preparation process, the holographic anti-counterfeiting layer needs to be coated, heated, cured, and then subjected to high-temperature molding, which not only affects preparation efficiency and wastes energy, but also uses a large amount of organic solvents during the coating process, making it less environmentally friendly. In addition, traditional anti-counterfeiting transfer materials often use a single-color holographic anti-counterfeiting layer as the carrier of graphic information, lacking color variability, resulting in a relatively monotonous holographic anti-counterfeiting effect, and also lacking the ability to display in dark environments. Therefore, the ability to reuse polyester film and separation layer in the preparation of anti-counterfeiting transfer materials makes the preparation process more efficient and environmentally friendly, while also giving the finished products a stunning holographic anti-counterfeiting effect. This represents a breakthrough technological innovation for existing technologies and aligns with industry development trends. Summary of the Invention

[0011] Prepare the required materials according to the table below: A method for preparing a novel anti-counterfeiting transfer material, the specific steps of which are as follows: 1) Using a coating machine, apply the release agent to the surface of the polyester film through a 280-300 mesh ceramic anilox roller.

[0012] The novel anti-counterfeiting transfer material prepared through the above embodiments not only realizes the reuse of polyester film and separation layer, but also makes the preparation process more efficient and environmentally friendly. At the same time, the product has a brilliant holographic anti-counterfeiting effect.

[0013] Based on the test results: (1) Example 1 uses a polyester film with a thickness of 20μm, which is slightly thicker than conventional anti-counterfeiting transfer materials. It is more suitable for flatbed hot stamping and can adapt to hot stamping of large-area graphics and irregular substrate surfaces. The flatbed hot stamping temperature is controlled at 115-165℃ and the hot stamping pressure is controlled at 3-8Mpa. If rotary hot stamping is used, the hot stamping temperature needs to be controlled at 180-220℃ and the hot stamping pressure needs to be controlled at 2-4Mpa. The hot stamping speed is slower and it is only suitable for small-area graphics. The preparation process needs to pay attention to the following: The following points should be considered: In the release agent formulation, appropriately increasing the proportion of short-chain hydrogen-containing polysiloxanes and silica powder can enhance the coating's cohesion and improve surface openness; otherwise, the stability and transfer effect of the release layer will be affected. In the molding coating formulation, increasing the proportion of low-viscosity unsaturated polyester resin and decreasing the proportion of acrylic-modified TPU ensures that the prepared holographic anti-counterfeiting layer possesses both excellent molding performance and good physical stability. During the preparation of the holographic anti-counterfeiting layer, the molding unit should be set to a lower pressure and lower temperature; otherwise, "over-pressing" may occur. (1) The image causes occasional loss of holographic anti-counterfeiting effect or dark spots; (2) Example 2 uses a polyester film with a thickness of 10μm, which is thinner than conventional anti-counterfeiting transfer materials. It has a better heat transfer effect between each coating and is more suitable for rotary hot stamping. It can adapt to high-speed hot stamping of fine graphics and continuous lines on thin paper substrates. The rotary hot stamping temperature is controlled at 165-200℃ and the hot stamping pressure is controlled at 1.5-3.5Mpa. If flat hot stamping is used, the hot stamping temperature needs to be controlled at 105-155℃. The hot stamping pressure is controlled at 4-7 MPa, which is only suitable for hot stamping on conventional graphics and substrates. It is not suitable for hot stamping on large-area graphics or irregular substrates. The following points should be noted during the preparation process: Increase the proportion of acrylic-modified TPU and hydroxypropyl methylcellulose in the molding coating formula to give the holographic anti-counterfeiting layer after shaping, curing and cross-linking excellent edge cutting properties, so as to ensure the coating accuracy during the hot stamping process; During the preparation of the holographic anti-counterfeiting layer, the molding unit should be set with relatively high pressure and temperature, otherwise the holographic anti-counterfeiting effect will be unsatisfactory.

[0014] In addition, it should be noted that: (1) The molding coating adopts the extrusion coating method, which significantly reduces the amount of organic solvent used in the coating compared with the traditional anilox roller coating. This not only saves manufacturing costs but is also very environmentally friendly; (2) Regardless of the implementation method, the solid content of the molding coating needs to be controlled at 50-80%. If the solid content is too low, uneven coating is likely to occur after extrusion coating, and regular grating patterns cannot be formed after holographic nickel plate imprinting; if the solid content is too high, extrusion coating will be difficult, and the molding unit will also find it difficult to imprint complete grating patterns at a relatively low set temperature. It should also be noted that the following technical measures are taken in this invention: the release agent uses silica powder with an average particle size of 5-6 μm and a bulk density ≥0.32 g / cm³; the molding coating uses phosphorescent powder with an average particle size of 3-5 μm and an excitation wavelength of 200-450 nm; the color-changing coating uses photochromic dye with a temperature resistance of 250℃ and an average particle size of 2-3 μm; the titanium dioxide powder with a refractive index of 2.8-2.9 and an average particle size of 0.15–0.20 μm; the mica powder with an iron content of <0.15% and an average particle size of 10-15 μm; and the hot melt adhesive coating uses hydrophobic nano-silica powder with an average particle size of 30-35 nm and a specific surface area of ​​300–350 m² / g. These measures are mainly determined by comprehensively considering the application performance requirements.

[0015] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various modifications and variations to the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the inventive concept of the present invention should be included within the protection scope of the present invention.
