Embodiment 1

[0032] A preparation method for a folding-resistant white hot stamping foil for leather, comprising the following steps:

[0033] 1) Biaxially stretched polyester film is used as the base film, hereinafter referred to as PET base film;

[0034] 2) Coating on the surface of the PET base film to form a release layer: mix 20% PU elastic resin and water to obtain a release layer coating; use a screen roller to apply the release layer material solution to the surface of the matte pre-coating , and then react and dry in a 4-stage high-temperature oven to form a release layer;

[0035] 3) Coating on the surface of the release layer to form a colored layer: mix 15% acrylic resin, 5% amino resin, 5% hydroxyl-modified acrylic resin and 75% methyl ethyl ketone and stir for 15 minutes, then Add 1% dye and stir for 10 minutes, and finally add 0.1% accelerator and stir for 3 minutes to make the coloring layer material solution; apply the coloring layer material solution to the surface of t...

Embodiment 2

[0040] A preparation method for a folding-resistant white hot stamping foil for leather, comprising the following steps:

[0041] 1) Biaxially stretched polyester film is used as the base film, hereinafter referred to as PET base film;

[0042] 2) Coating on the surface of the PET base film to form a release layer: mix 30% PU elastic resin and methanol to obtain a release layer coating; use a screen roller to coat the release layer material solution on the surface of the matte pre-coating , and then react and dry in a 6-stage high-temperature oven to form a release layer;

[0043] 3) Coating on the surface of the release layer to form a colored layer: Mix 30% acrylic resin, 20% amino resin, 9% hydroxyl-modified acrylic resin and 50% butyl ester and stir for 30 minutes, then Add 11% dye and stir for 20 minutes, and finally add 2% accelerator and stir for 6 minutes to make the coloring layer material solution; apply the coloring layer material solution to the surface of the rel...

Embodiment 3

[0048] A preparation method for a folding-resistant white hot stamping foil for leather, comprising the following steps:

[0049] 1) Biaxially stretched polyester film is used as the base film, hereinafter referred to as PET base film;

[0050] 2) Coating on the surface of the PET base film to form a release layer: mix 25% PU elastic resin and alcohol to obtain a release layer coating; use a screen roller to apply the release layer material solution to the surface of the matte pre-coating , and then react and dry in a 4-stage high-temperature oven to form a release layer;

[0051] 3) Coating on the surface of the release layer to form a colored layer: Mix 20% acrylic resin, 15% amino resin, 5% hydroxyl-modified acrylic resin and 60% ethyl ester and stir for 20 minutes, then Add 5% dye and stir for 15 minutes, and finally add 1% accelerator and stir for 5 minutes to make the coloring layer material solution; use the screen roller to coat the coloring layer material solution on...

Abstract

The invention discloses creasing and folding resistance hot stamping foil for leather. The creasing and folding resistance hot stamping foil comprises a PET base film; a release layer, a coloring layer, an aluminum plating layer and a back glue layer are coated on the PET base film in sequence; the PET base film is 15-25 microns thick, and achieves low surface tension, high transparency and temperature resistance suitable for the printing industry; the release layer has the characteristic of high-temperature resistance, can protect the coloring layer from being eroded by external environment,and meanwhile, achieves fissility and creasing and folding resistance; the coloring layer achieves temperature resistance, cannot generate the color change and light elimination phenomenon in high-temperature stamping, and meanwhile, is higher in brittleness; the aluminum plating layer can improve the brightness of a heat transfer film to achieve the metal gloss; and the back glue layer is thermoplastic high-elasticity polyurethane, can guarantee firm combination between a color layer and an aluminum layer with the surface of a printed matter, and meanwhile, improves the product toughness, leather feeling and grade. The creasing and folding resistance hot stamping foil is high in leather feeling, higher in brightness, bright in color and excellent in wear resistance and solvent resistance, and can form different patterns on products.

Description

technical field [0001] The invention relates to a folding-resistant white hot stamping foil for leather and a preparation method thereof. Background technique [0002] As a new type of printing and decoration material, hot stamping foil has the characteristics of environmental protection, high efficiency and energy saving, and has a wide range of applications. Ordinary leather can fully demonstrate the characteristics of nobility, generosity and fashion after being decorated with hot stamping foil. However, due to the limitations of the production process and production technology, the traditional hot stamping foil has a single pattern and poor brightness, especially it is not resistant to folding. The fogging of the coating after folding greatly affects the aesthetics of the product and limits the promotion of the product. application. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a hot stamping foil...
