preparation example Construction

[0051] The preparation method of above-mentioned electrochemical aluminum provided by the present invention comprises the following steps:

[0052] Provide a base layer.

[0053] Coat the release agent on one side of the base layer, the dry coating amount of the release agent is 0.05~0.3g / m 2 , and dried to obtain a release layer.

[0054] Coat alcohol-soluble color ink on the side of the release layer away from the base layer, 0.5-5.0g / m of alcohol-soluble color ink 2 , and dried to obtain the color layer.

[0055] The aluminum layer is made by plating aluminum on the side of the color layer away from the release layer.

[0056] Coat the glue solution on the side of the aluminum layer away from the color layer, the dry coating amount of the glue solution is 0.5~2.0g / m 2 , and dried to obtain the adhesive layer.

[0057] Optionally, the base layer is a polyethylene terephthalate resin (Poly(ethylene terephthalate), PET) film, and the thickness of the base layer is 12-36 μ...

Embodiment 1

[0071] Coating release agent on one side of PET film with a thickness of 12μm, the dry coating amount is 0.05g / m 2 , dried to obtain a release layer. Wherein, the release agent includes water-soluble modified silicone resin, and its solid content is 1%.

[0072] Coating alcohol-soluble color ink on the release layer, the dry coating amount is 1.7g / m 2 , dried to obtain a color layer. Among them, the binder of the alcohol-soluble color ink is polyvinyl butyral and rosin resin with a weight ratio of 5:1, and the toner, additives, and solvents of the alcohol-soluble color ink are selected from environmentally friendly materials and adjusted according to the needs.

[0073] A vacuum aluminum plating machine is used to carry out vacuum aluminum plating on the color layer to form an aluminum layer with a thickness of 10 nm.

[0074] Coating glue on the aluminum layer, the dry coating amount is 1.0g / m 2 , dried to obtain a glue layer, and finally obtain the finished electrochemic...

Embodiment 2

[0079] Coating release agent on one side of PET film with a thickness of 20μm, the dry coating amount is 0.1g / m 2 , dried to obtain a release layer. Wherein, the release agent includes a water-soluble modified silicone resin, and its solid content is 5%.

[0080] Coating alcohol-soluble color ink on the release layer, the dry coating amount is 3g / m 2 , dried to obtain a color layer. Among them, the binder of the alcohol-soluble color ink is polyvinyl butyral and rosin resin with a weight ratio of 1:1, and the toner, additives, and solvents of the alcohol-soluble color ink are selected from environmentally friendly materials and adjusted according to the needs.

[0081] A vacuum aluminum plating machine is used to carry out vacuum aluminum plating on the color layer to form an aluminum layer with a thickness of 12nm.

Abstract

The invention provides electric aluminum suitable for low-temperature hot stamping. An adhesive layer is formed by coating of an adhesive. The adhesive is composed of, by weight, 1-40 parts of a low-softening-point resin compound, 10-90 parts of solvent and 0.2-10 parts of auxiliaries, wherein the low-softening-point resin compound at least comprises 1-20 parts of polyamide resin and 1-10 parts of rosin resin. According to the aluminum suitable for low-temperature hot stamping, the low-softening-point resin compound comprises the polyamide resin and the rosin resin of certain proportions, the prepared adhesive is stable in performance through the mutual effect of the polyamide resin and the rosin resin, the melting temperature of the adhesive layer formed by coating of the adhesive can be controlled to be 50-110 DEG C, thus hot stamping is conducted under the condition of low temperature of 70-120 DEG C, and high energy consumption is avoided; and besides, the severe loss of moisture in a hot-stamped material and thermal expansion of a hot stamping plate are avoided, the rejection rate is decreased, and the product cost is reduced.

Description

technical field [0001] The invention relates to the technical field of anodized aluminum, in particular to an anodized aluminum suitable for low-temperature hot stamping and a preparation method thereof. Background technique [0002] Anodized aluminum is a hot stamping material made by coating a release layer and a color layer on the base layer of a film, and then coating an adhesive layer after a vacuum aluminized layer, and finally rewinding the finished product. Hot-stamp suitable anodized aluminum on the tipping paper for cigarettes through a hot stamping machine, endow the hot-stamping substrate with a strong metallic texture, provide bright colors, dazzling effects, etc., and can significantly enhance the decorative effect and anti-counterfeiting effect of the tipping paper Obviously, improve the product grade of tipping paper. [0003] Traditionally, the aluminum foil hot stamping method is used on the tipping paper, that is, with the help of a certain pressure and t...
