Embodiment 1

[0029] like figure 1 As shown, the present invention includes that the BOPET film and the metal aluminum foil provided with the three-dimensional pattern are bonded together through a colored composite adhesive layer. The surface of the BOPET film is provided with a three-dimensional pattern layer formed by UV radiation curing using precision micro-replication engraving technology; the surface of the metal aluminum foil layer is provided with a hot-melt adhesive composite resin layer to improve bonding strength. Its preparation method comprises the following steps:

[0030] (1) Select the base film: select a bending-resistant and impact-resistant BOPET film.

[0031] (2) Coating primer layer: apply a primer with excellent adhesion fastness and no sticking back on the surface of the BOPET film.

[0032] (3) Preparation of three-dimensional effect pattern layer: the three-dimensional pattern layer is formed on the surface of the BOPET film by UV radiation curing using precisio...

Embodiment 2

[0039] The BOPET film of this embodiment is resistant to 180 º Bending life 1.5×10 4 Times, impact strength 90kj / m, tear strength 57 N / mm, tensile strength 108MPa, elongation at break 24%. The primer is selected from a yellowing-resistant polyurethane resin with excellent adhesion fastness and no stickiness. A three-dimensional pattern layer formed by UV radiation curing using precision micro-replication marking technology. The three-dimensional pattern is a flashing pattern imitating a golden monkey, with a thickness of 5±0.3μm. The colored composite adhesive layer is a high-temperature cooking-resistant solvent-based polyurethane composite adhesive with high bonding strength to BOPET film and metal aluminum foil. The composite strength is 180º, the peel strength is 35±2MPa, the boiling temperature is 101°C, and the boiling time is 85min. . The colored pigment in the colored composite adhesive is composed of black pigment and white pigment according to the mass ratio of 20...

Embodiment 3

[0042] The BOPET film of this embodiment is resistant to 180 º Bending life 2.0×10 4 Times, impact strength 100kj / m, tear strength 52 N / mm, tensile strength 120MPa, elongation at break 30%. The primer is selected from the anti-yellowing polyurethane resin with excellent adhesion fastness and no sticking back and the dual-cure system polyacrylate resin is mixed according to the mass ratio of 75:25wt%. A three-dimensional pattern layer formed by UV radiation curing using precision micro-replication marking technology. The three-dimensional pattern is a flash pattern imitating a combination of ribs and stainless steel rings, with a thickness of 4.5±0.3μm. The colored composite adhesive layer is a high-temperature cooking-resistant solvent-based polyurethane composite adhesive with high bonding strength to BOPET film and metal aluminum foil. The time is 75 minutes. The colored pigment in the colored composite adhesive is made of black pigment and white pigment according to the ...

Abstract

The invention relates to a metal-imitated color plate membrane with a three-dimensional effect, and a preparation method of the metal-imitated color plate membrane. The metal-imitated color plate membrane comprises a biax orientation polyester (BOPET) film layer and a metal aluminum foil layer, wherein a primer coating layer is arranged on the upper surface of the BOPET film layer, and a three-dimensional pattern layer is arranged on the upper surface of the primer coating layer; the lower surface of the BOPET film layer is stuck with the metal aluminum foil layer by a colored composite adhesive layer; the lower surface of the metal aluminum foil layer is provided with a hot melt adhesive composite resin layer used for improving bonding strength. The preparation method comprises the processing steps of selecting a base membrane, coating the primer coating layer, preparing the three-dimensional pattern layer, coating the composite adhesive layer, compounding metal aluminum foil, and coating the hot melt adhesive composite resin layer. The metal-imitated color plate membrane has decorative patterns with the three-dimensional effect, is high in metal texture and soft in luster, and has novel and unique appearance, so that the product grade is improved, and the product categories are enriched.

Description

technical field [0001] The invention relates to a composite decorative film for color steel plates and a preparation method thereof, in particular to a metal imitation color plate film with a three-dimensional effect and a preparation method thereof.
