Problems solved by technology

In recent years, with the improvement of people's living standards and the development of the country's economy, people pay more and more attention to the appearance and exquisite packaging of various products. The pattern printed by hot stamping foil shows a strong metallic luster and bright colors. It will never fade, and its brightness is much higher than that of ink printing, so that the product has a high-end feeling and gives people a beautiful enjoyment, which improves the artistry of the product, so bronzing is widely used in all walks of life, and bronzing technology has also been rapidly improved. As the crystallization of high-tech, anti-counterfeiting marks are widely used in various industries and fields. Laser anti-counterfeiting anodized aluminum is mostly used in the processing form of hot stamping on paper and cloth in the anti-counterfeiting industry. Not only the substrate is soft, but also the thickness is small, which is convenient for hot stamping operations. However, the application of laser holographic technology in the manufacture of metal coins is still in its infancy when hot stamping laser holographic marks on metal coins. Metal coins are very different from ordinary substrates in the industry due t

Embodiment 1

[0025] Such as figure 1 Shown is the production flow chart of the present invention for laser anodized hot stamping foil on metal coins. exist figure 1 Among them, the preparation method of laser anodized aluminum hot stamping foil for metal coins of the present invention comprises the following steps:

[0026] Step 1), making the metal nickel plate: use a photolithography machine to engrave the image and text on the photosensitive rubber plate to produce a laser holographic plate, and then use the electroforming method to make the laser holographic plate into a metal nickel plate for molding;

[0027] Step 2) as in figure 2 As shown, coating the release layer 2 on the base film film belt 1: prepare the melamine resin release layer coating according to the release layer composition components: in parts by mass, the raw material solvent of the melamine release agent is 40 mass of alcohol parts, 30 parts by mass of butanone, 0.007 parts by mass of auxiliary agent, and 70 p...

Embodiment 2

[0033] This embodiment can also have the following differences, and the rest are the same as in Example 1, and the same parts will not be repeated. In step 2) of the present invention, the following differences can also be found: 2) In the basic Coating release layer 2 on film tape 1: prepare melamine resin release layer coating according to release layer composition components: in parts by mass: melamine release agent whose raw material solvent is 45 parts by mass of alcohol, 35 parts by mass of methyl ethyl ketone Parts by mass, 0.008 parts by mass of auxiliary agent, 80 parts by mass of melamine resin were stirred and mixed uniformly for 20 minutes to make a release layer coating and coated on a base film tape 1 by a coating machine to form a release layer 2. The auxiliary agent is Hardener;

[0034] Molding in step 4): the holographic anti-counterfeiting pattern on the metal nickel plate is molded and transferred to the imaging layer 3 by a molding press equipped with the ...

Embodiment 3

[0037] This embodiment can also have the following differences, and the rest are the same as in Example 1, and the same parts will not be repeated. In step 2) of the present invention, there can also be the following differences: step 2) in the described Coating release layer 2 on the base film film belt 1: the release layer 2 is a melamine release layer, and the melamine resin release layer coating is prepared according to the composition of the release layer: in parts by mass: solvent alcohol 50 Parts by mass, 32 parts by mass of methyl ethyl ketone, 0.008 parts by mass of additives, 82 parts by mass of melamine resin were stirred evenly and mixed with a high-speed mixer for 20 minutes, and the two coating adhesive materials in step 6) of the present invention were two The thermoplastic adhesive of two components, the thermoplastic adhesive of the first coating is polyurethane, the thermoplastic adhesive of the second coating is acrylic, and the adhesive is coated with a coat...

Abstract

The invention relates to the technology of laser holography anti-counterfeiting hot stamping, in particular to a preparation method for laser hot stamping foil of a metal coin and prepared laser hot stamping foil by using the method, and provides a preparation method for laser hot stamping foil of a metal coin and prepared laser hot stamping foil by using the method, which can adapt to gold stamping on the surface of the metal coin, enrich patterns on the surface of the metal coin, has an anti-counterfeiting function and is suitable for printing after stamping. The preparation method comprises the steps that a metallic nickel plate is manufactured, and a release layer, an imaging layer, a mold pressing layer, an aluminum coated layer and an adhesive layer are coated on a basement membrane strip, so that the metal coin has a brand-new effect, the operation process is simple and rapid, reproducibility of texts is good, large-scale production and durability are realized, the cost is reduced, the adhesion of the laser hot stamping foil is high, after being fastened on the surface of a metal product, the hot stamping foil does not easily fall off and has a smooth surface, through changing the formula of the adhesive layer and coating the adhesive layer for multiple times, a multi-layer bonding layer is formed, so that texts are firmly adhered on the surface of the metal, and wear resistance and weather fastness are realized.

Description

technical field [0001] The invention relates to laser holographic anti-counterfeiting hot stamping technology, in particular to a preparation method of laser anodized aluminum hot stamping foil for metal coins and the laser anodized aluminum hot stamping foil made by the method. Background technique [0002] Hot stamping is a process of stamping anodized aluminum, commonly known as hot stamping foil, onto the surface of the substrate under a certain temperature and pressure. In recent years, with the improvement of people's living standards and the development of the country's economy, people pay more and more attention to the appearance and exquisite packaging of various products. The pattern printed by hot stamping foil shows a strong metallic luster and bright colors. It will never fade, and its brightness is much higher than that of ink printing, so that the product has a high-end feeling and gives people a beautiful enjoyment, which improves the artistry of the product,...
