A decoration pattern of the decoration pattern layer 30 can be portrait, landscape, animal, auspicious pattern, graining pattern, leather pattern, or 3D image. Colors of the decoration pattern layer 30 can be single color or color combinations. In this embodiment, a plurality of pattern gap 301 is defined in the decoration pattern layer 30, and the adhesive layer 20 is filled into the pattern gap 301. The decoration pattern layer 30 is cured by UV curing ink.
The coating layer 40 covers a surface of the decoration pattern layer 30 away from the decoration surface 101 to protect the decoration pattern layer 30. In this embodiment, the coating layer 40 also covers the adhesive layer 20 in the pattern gap 301. A thickness range of the coating layer 40 is about 5 micrometers to about 50 micrometers, preferably, is about 10 micrometers. The coating layer 40 can be made of rigid resin, such as acrylic glass or polymethylmethacrylate (PMMA).
In other embodiment, the pattern gap 301 can be omitted, thus, the coating layer 40 is not contact with the adhesive layer 20.
Referring to FIG. 3, a flowchart is presented in accordance with an exemplary embodiment for manufacturing the decoration glass 100. The exemplary method is provided by way of example, as there are a variety of ways to carry out the method. The method described below can be carried out using the configurations illustrated in FIGS. 2a, 2b, 2c and 1, and various elements of these figures are referenced in explaining the exemplary method. Each block shown in FIG. 3 represents one or more processes, methods, or subroutines, carried out in the exemplary method. Additionally, the illustrated order of blocks is by example only and the order of the blocks can change.
At block 302, a transparent film, a releasing film, and a coating layer are provided and successively stacked to form a first multilayer film.
FIG. 2a illustrates that a transparent film 50, a releasing film 60, and a coating layer 40 are successively stacked to form a first multilayer structure 70. In this embodiment, the transparent film 50 is made of polyolefin (PO). A thickness range of the transparent film 50 is about 100 micrometers to about 200 micrometers, preferably, is about 125 micrometers. The releasing film 60 can be a film with low adherence to adhered to the transparent film 50 and the coating layer 40, and to easily be removed. A thickness range of the releasing film 60 is about 1 micrometer to about 10 micrometers, preferably, is about 5 micrometers.
The transparent film 50, the releasing film 60, and the coating layer 40 in thickness of this embodiment provide support and transmittance.
In other embodiment, the first multilayer structure 70 may have more layers.
At block 304, a decoration pattern layer 30 is formed on a surface of the coating layer 40.
FIG. 2b illustrates that a decoration pattern layer 30 is formed on a surface of the coating layer 40. The decoration pattern layer 30 is formed by inkjet, or screen printing. The decoration pattern layer 30 is made of UV curing ink.
At block 306, a transparent base 10 having a decoration surface and an adhesive layer 20 are provided. The decoration surface of the transparent base 10 is adhered to the decoration pattern layer 30 of the first multilayer film by the adhesive layer 20, to form a second multilayer film 80.
FIG. 2c illustrates that a transparent base 10 is formed on a surface of the decoration pattern layer 30 through an adhesive layer 20, therefore, a second multilayer film 80 is obtained. The transparent base 10 includes a decoration surface 101, and the decoration surface 101 is cleaned before forming on the surface of the decoration pattern layer 30.
At block 308, the transparent film 50 and the releasing film 60 are softened by a heat-softening process.
In this embodiment, the transparent film 50 and the releasing film 60 are softened by the heat-softening process in a heating temperature in a range of about 80 degree Celsius to about 150 degree Celsius.
At block 310, the second multilayer film 80 is received in a vacuum cavity, therefore, each layer of the second multilayer film 80 can be completely in contact with at least an adjacent layer by a vacuuming process.
At block 312, the decoration pattern layer 30 is cured by an UV curing process. In this embodiment, UV light is passed through the transparent layer 50 to cure the adhesive layer 20 and the decoration pattern layer 30. The adhesive layer is also cured by the UV curing process.
At block 314, the transparent film 50 and the releasing film 60 are removed, therefore, a decoration glass 100 is obtained.
FIG. 1 illustrates that the decoration pattern layer 30 is embedded by the coating layer 40.
