Problems solved by technology

However, after the holographic information anti-counterfeiting anodized aluminum material of the prior art is hot stamped on the surface of the cloth, some problems such as poor bonding, exposed bottom, blurred graphics and unclear holographic patterns cannot achieve the anti-counterfeiting effect; It’s okay, but it’s not resistant to washing, soaping, or bending, stretching, and rubbing. After washing or bending, stretching, and rubbing, the hot stamping pattern is missing, or the pattern information layer is damaged, and the anti-counterfeiting effect is lost; some anti-counterfeiting The logo or label can also be easily removed and reused

Embodiment 1

[0043] The holographic information anodized aluminum material of this embodiment is prepared through the following steps:

[0044] (1) Coating the liquid raw material of the release layer on the clean PET substrate layer by a coating machine, drying to form the release layer;

[0045] (2) Mix the liquid raw materials of polymethyl methacrylate, the liquid raw materials of fluororesin A, and the liquid raw materials of fluororesin B according to the required ratio to make a liquid coating, and apply it on the separator by a coating machine. Outside the pattern layer, dry to form the imaging material layer, which must be used for the composite material tape of step (3);

[0046] (3) single-mode pressing the composite strip under the condition of double hard rolls, the imaging material layer is molded by a nickel plate, and another hard roll presses the substrate layer to form a holographic imaging layer;

[0047] (4) Print two-dimensional codes, digital information and graphic ...

Embodiment 2-5、 comparative example 1-7

[0058] Basically according to the steps (1)-(7) of Example 1, prepare the electrochemical aluminum materials of each embodiment and comparative example, the difference is that in step (2), the liquid raw material of polymethyl methacrylate used and the amount of fluorine-containing resin Liquid raw materials, the batching ratio by resin is listed in Table 2 successively, but according to the actual need to add or subtract the feeding amount of each raw material, wherein comparative example 8 adopts the polyvinylidene fluoride water-based coating of relative molecular weight 5000 (800 after evaporation to dryness). ℃ Ash≤0.1m%).

[0059] The compatibility of each emulsion batching in embodiment 2-5, comparative example 1-10 is all very good, is all easy to mix, after mixing, it is all very stable in storage at room temperature within 2 days, and in use; use the 300 mesh The effect of anilox roll coating is better, and the coating speed, drying conditions, and dry coating amount...

Embodiment 6-8

[0066] Basically according to the steps (1)-(7) of Example 5, the anodized aluminum materials of each Example 6-8 were prepared, the difference being the temperature, pressure, and line speed conditions during molding in step (3), as listed in Table 2 below .

[0067] Temperature, pressure, line speed conditions during molding in table 2 step (3)

[0068] temperature °C pressure MPa Linear speedm / min Example 5 180 0.8 45 Example 6 180 1.0 50 Example 7 180 0.6 35 Example 8 160 0.8 20 Example 9 200 0.3 50

[0069] The anodized aluminum materials obtained in Examples 6-8 above have high reflective brightness, clear and crisp holographic details, and clear and sharp digital information and graphic characters, all of which have reached the quality level in these aspects.

Abstract

The invention provides a high-temperature-resistant holographic information alumite material for hot stamping of a cloth cover. The high-temperature-resistant holographic information alumite material comprises a base material layer, a release layer, a holographic imaging layer, an information digital layer, an aluminized layer and a back adhesive layer which are combined and laminated from top to bottom, the holographic imaging layer and the information digital layer have the functions of hot stamping resistance, laser holography and informatization anti-counterfeiting; the holographic imaging layer is formed by pressing a mixed coating film containing polyacrylate and fluorine-containing resin in a mass ratio of 100: (8-20) through a single mold under the conditions of the temperature of 160-220 DEG C, the pressure of 0.1-1.0 MPa and double hard rollers, and a nickel plate is adopted during mold pressing. The alumite material has triple effects of high temperature resistance, laser holographic anti-counterfeiting and informatization anti-counterfeiting; high-speed hot stamping can be achieved, hot stamping patterns are clear, the reflection brightness is high, and observed holographic image details are clear and bright; the hot stamping is firm, the base is not exposed, no image-text floating exists, and friction, bending and stretching are resisted; and complete and intact uncovering and reutilization are not easy to realize. The information digital layer is not easy to damage after the cloth cover of the hot stamping alumite material is washed.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting materials, and in particular relates to a high-temperature-resistant holographic information anodized aluminum material for hot stamping on cloth, a preparation method and application thereof. Background technique [0002] As an anti-counterfeit printing material, conventional holographic information anodized aluminum can be used in fields such as cigarette labels and wine labels. It is usually pasted on relatively smooth plastic and glass surfaces. However, after the holographic information anti-counterfeiting anodized aluminum material of the prior art is hot stamped on the surface of the cloth, some problems such as poor bonding, exposed bottom, blurred graphics and unclear holographic patterns cannot achieve the anti-counterfeiting effect; It’s okay, but it’s not resistant to washing, soaping, or bending, stretching, and rubbing. After washing or bending, stretching, and rubbing, t...
