Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum hot stamping foil technology, and in particular to a multi-release composite electroplated aluminum hot stamping foil. Background Technology

[0002] The electroplated aluminum industry has developed rapidly, and the wide variety and applications of electroplated aluminum hot stamping foil permeate people's daily lives. From small items like paper packaging and UnionPay card magnetic strips to large-scale applications like automobiles, tower cranes, and bridge surface anti-corrosion, electroplated aluminum hot stamping is involved to varying degrees. It can be said that the emergence of electroplated aluminum hot stamping foil has almost revolutionized many industries such as traditional printing, gilding, electroplating, and physical coating. Existing electroplated aluminum hot stamping foil usually uses a single release layer, which can only achieve the hot stamping effect in a single area. For complex patterns or multi-color hot stamping requirements, multiple overprints or foil replacements are required. Moreover, single release layers have problems such as unstable release force and poor adhesion, which easily lead to blurred edges or peeling of the hot stamping pattern. To address these issues, we have proposed a multi-release composite electroplated aluminum hot stamping foil. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a multi-release composite electroplated aluminum hot stamping foil. This invention solves the problem that existing electroplated aluminum hot stamping foils typically use a single release layer, which can only achieve a hot stamping effect in a single area. For complex patterns or multi-color hot stamping requirements, multiple overprints or foil replacements are necessary. Furthermore, single release layers suffer from unstable release force and poor adhesion, easily leading to blurred edges or peeling of the hot stamped pattern.

[0004] This utility model discloses a multi-release composite electroplated aluminum hot stamping foil, comprising a substrate film layer, a lower release layer above the substrate film layer, an upper release layer on the side of the lower release layer away from the substrate film layer, the lower release layer and the upper release layer forming a gradient release structure, a color layer on the side of the upper release layer away from the lower release layer, a fluorescent layer on the side of the color layer away from the upper release layer, a vacuum-plated aluminum layer on the side of the fluorescent layer away from the color layer, and an adhesive layer on the side of the vacuum-plated aluminum layer away from the fluorescent layer.

[0005] In the above scheme, the substrate film layer is a biaxially oriented polyester film layer, and the thickness of the substrate film layer is 6nm to 12nm.

[0006] In the above scheme, the lower release layer is a modified silicone resin material layer.

[0007] In the above scheme, the upper release layer is patterned using microgravure coating technology to create the structural layer.

[0008] In the above scheme, the fluorescent layer is a non-water-soluble fluorescent polymer layer, and the thickness of the fluorescent layer is 5nm to 15nm.

[0009] In the above scheme, the adhesive layer is a water-based acrylic adhesive layer.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a multi-release composite electroplated aluminum hot stamping foil. The substrate film layer is a biaxially oriented polyester film layer, which effectively ensures the overall mechanical strength of the electroplated aluminum hot stamping foil. The lower release layer uses modified silicone resin material with a release force of 5-10N / 25mm. The upper release layer is a patterned release layer formed by micro-gravure coating technology with a release force of 15-25N / 25mm. Through the gradient release design of the lower and upper release layers, it ensures both rapid release of the electroplated aluminum hot stamping foil over a large area and precise control of fine areas. Fluorescent microcapsules or nano-color-changing particles are embedded in the lower and upper release layers, which can achieve ultraviolet excitation or temperature-sensitive anti-counterfeiting effects. This type of electroplated aluminum hot stamping foil has good stretching effect and strong adhesion, and can achieve rapid release of a large area while also achieving precise control of fine areas, effectively improving the practicality of the electroplated aluminum hot stamping foil.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] like Figure 1As shown, this utility model is a multi-release composite electroplated aluminum hot stamping foil, including a substrate film layer 1, a lower release layer 2 above the substrate film layer 1, and an upper release layer 3 on the side of the lower release layer 2 away from the substrate film layer 1. The lower release layer 2 is made of modified silicone resin material, with a release force of 5-10N / 25mm, which can be used for rapid release over large areas, avoiding the adhesion of the electroplated aluminum hot stamping foil. The upper release layer 3 is formed into a patterned release layer through micro-gravure coating technology, with a release force of 15-25N / 25mm, which can achieve controllable release in local fine areas, thereby achieving precise control of the edges of complex patterns. The lower release layer 2 and the upper release layer 3 are a gradient release structure, and fluorescent microcapsules or nanoparticles are embedded in the lower release layer 2 and the upper release layer 3. Color-changing particles enable ultraviolet-activated or temperature-sensitive anti-counterfeiting effects. The gradient release design of the lower release layer 2 and upper release layer 3 ensures rapid release of large areas of the electroplated aluminum foil while achieving precise control over fine areas. A color layer 4 is located on the side of the upper release layer 3 away from the lower release layer 2. A fluorescent layer 5 is located on the side of the color layer 4 away from the upper release layer 3. A vacuum-plated aluminum layer 6 is located on the side of the fluorescent layer 5 away from the color layer 4. The vacuum-plated aluminum layer 6 undergoes vacuum evaporation, resulting in a reflectivity of up to 95% for the electroplated aluminum foil, allowing it to shine brilliantly under light. An adhesive layer 7 is located on the side of the vacuum-plated aluminum layer 6 away from the fluorescent layer 5. The adhesive layer 7 incorporates nano-silica particles, increasing adhesion to 5N / cm, ensuring a permanent bond between the hot-stamped pattern and the substrate, preventing it from peeling off after washing.

[0016] The substrate film layer 1 is a biaxially oriented polyester film layer with a thickness of 6nm to 12nm. The biaxially oriented polyester film layer effectively ensures the overall mechanical strength of the electroplated aluminum hot stamping foil.

[0017] The lower release layer 2 is a modified silicone resin material layer.

[0018] The upper release layer 3 is a patterned structural layer created using microgravure coating technology.

[0019] The fluorescent layer 5 is a non-water-soluble fluorescent polymer layer, and the thickness of the fluorescent layer 5 is 5nm to 15nm.

[0020] The adhesive layer 7 is a water-based acrylic adhesive layer.

[0021] Specifically, in this invention, the substrate film layer 1 is a biaxially oriented polyester film layer, which effectively ensures the overall mechanical strength of the electroplated aluminum hot stamping foil. The lower release layer 2 is made of modified silicone resin material with a release force of 5-10N / 25mm. The upper release layer 3 is a patterned release layer formed by microgravure coating technology with a release force of 15-25N / 25mm. Through the gradient release design of the lower release layer 2 and the upper release layer 3, it ensures both rapid release of the electroplated aluminum hot stamping foil over a large area and precise control of fine areas. Fluorescent microcapsules or nano-color-changing particles are embedded in the lower release layer 2 and the upper release layer 3, which can achieve ultraviolet excitation or temperature-changing anti-counterfeiting effects. The vacuum-plated aluminum layer 6 is vacuum-deposited, making the reflectivity of the electroplated aluminum hot stamping foil as high as 95%, which can bloom with a brilliant luster under light. The adhesive layer 7 adds nano-silica particles, which increases the adhesion to 5N / cm, allowing the hot stamping pattern to be permanently bonded to the substrate and not to fall off after washing.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
