Abstract
Instead of a heavy and difficult-to-handle glass, a polymer sheet of transparent material is used to provide a three-dimensional, metallic-like interior sheet having a metal-like appearance effect and a method of manufacturing the same.
The interior sheet according to the present invention includes a polymer film; A UV cured coating layer formed on one surface of the polymer film; A metal deposition layer formed on the polymer film and the UV cured coating layer; And a printing layer formed on the metal vapor deposition layer.
Description
The present invention relates to an interior sheet and a method of manufacturing the same. More specifically, the present invention relates to an interior sheet made of a transparent material, .
BACKGROUND ART [0002] Generally, back-side printed plate glass is used to give transparency and high surface hardness in household appliances such as refrigerators and air conditioners, architectural furnishings such as closets, and furniture.
Such a flaky glass is obtained by adding a dull pattern to the back surface of a glass. Silk screen printing is usually performed on the back surface of the glass, or an interior film is attached to realize a pattern. In addition, metal deposition may be separately performed on the print layer to add the metallic color.
On the other hand, such a glass product has a surface hardness of 7 to 8H and maintains high hardness and excellent scratch resistance. However, such conventional glass products are disadvantageous in that they are heavy in weight. In addition, there is a high risk of breakage during transportation due to weak external impact, and it is difficult to cut into a desired shape due to the characteristics of the glass material, and thus the workability is deteriorated.
Among these glass-use interior products, there are two types of products having three-dimensional patterns and metallic colors. A method of depositing a metal after forming a fine pattern coating layer with a thermosetting resin directly on the glass and a method of forming a UV pattern layer on a PET-based transparent polymer film and then adhering a film made by depositing a metal on the glass . The method of depositing a metal directly after forming a three-dimensional patterned layer on a glass is excellent in appearance and not only lowers the production efficiency during various post-processes, but also causes high manufacturing costs because of high breakage and defective ratio. Moreover, it is difficult to apply to various sizes of products since it is impossible to cut after completion.
In addition, in the method of depositing a three-dimensional pattern layer on a film and depositing the film, a transparent adhesive layer is inserted between the glass and the film, which deteriorates appearance effects such as three-dimensional effects due to changes in light transmittance and refractive index.
Korean Patent No. 10-0847342 (published on July 21, 2008) discloses a decorative sheet, a decorative glass using the decorative sheet, and a manufacturing method thereof.
It is an object of the present invention to provide an interior sheet of metal texture which is excellent in stereoscopic effect due to transparency unique to glass and which is light in weight, excellent in handling and processability, and excellent in decorative effect on appearance.
An object of the present invention is to provide an interior sheet of a metal texture which is excellent in handling and workability and can be rolled in a roll form and is worked in a sheet form to thereby provide a metal- Method.
According to an aspect of the present invention, there is provided an interior sheet comprising: a polymer film; A UV cured coating layer formed on one surface of the polymer film; A metal deposition layer formed on the polymer film and the UV cured coating layer; And a printing layer formed on the metal vapor deposition layer.
According to another aspect of the present invention, there is provided a method of manufacturing an interior sheet, comprising: (a) applying a UV curable polymer resin on one side of a polymer film and curing the UV curable polymer resin to form a UV curable coating layer; (b) depositing a metal on the lower surface of the polymer film having the UV cured coating layer to form a metal deposition layer; And (c) forming a print layer on the metal deposition layer.
The present invention can produce an interior sheet having a three-dimensional and metal-like appearance effect by using a polymer sheet of a transparent material in place of a heavy and difficult-to-handle glass. The interior sheet thus produced can be used as furniture, .
In addition, the present invention has transparency unique to glass, which not only has excellent stereoscopic effect but also light weight, excellent handling and processability and can be rolled in a roll form, thereby allowing work to be performed in a sheet form, An inexpensive interior sheet can be manufactured.
Therefore, the interior sheet and the manufacturing method thereof according to the present invention have advantages similar to those of using glass, and are advantageous in that they can be easily installed by using an adhesive since they are considerably lightweight compared to glass products which are fixed by a frame or made of silicone .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing an interior sheet of a metal texture with excellent appearance decoration effect according to an embodiment of the present invention will be described with reference to the accompanying drawings.
3 is a process flow diagram illustrating an interior sheet manufacturing method according to an embodiment of the present invention.
Referring to FIG. 3, an interior sheet manufacturing method according to an embodiment of the present invention includes a UV curing coating layer forming step S210, a metal deposition layer forming step S220, and a printing layer forming step S230.
UV curing coating layer formation
In the UV cured coating layer forming step S210, a UV curable polymer resin is applied to one surface of the polymer film and cured to form a UV cured coating layer.
The
In this step, the UV curable polymer resin comprises 85 to 95% by weight of oligomer acrylate and 5 to 15% by weight of photoinitiator, based on 100% by weight of the photocurable resin. At this time, as the oligomer acrylate, at least one selected from urethane acrylate, urethane methacrylate, epoxy acrylate, epoxy methacrylate, ester acrylate, and ester methacrylate may be used.
The UV curable polymer resin may further comprise 10 to 30 parts by weight of an organic solvent per 100 parts by weight of the photocurable resin. As the organic solvent, for example, propyl alcohol may be used. At this time, if the content of the organic solvent is less than 10 parts by weight, the fluidity is drastically lowered, and it may be difficult to coat the polymer film with a uniform thickness. On the other hand, if the content of the organic solvent is more than 30 parts by weight, the fluidity may be excessively increased, and the polymer may not be coated on the polymer film and flow down.
Metal deposition layer formation
In the metal deposition layer formation step S220, a metal deposition layer is formed by depositing a metal on the lower surface of the polymer film having the UV curing pattern layer formed thereon. At this time, the metal deposition layer may be formed of at least one selected from aluminum (Al), stainless steel (SUS), nickel (Ni) and chromium (Cr) The metal deposition layer may be formed by using any one method selected from sputtering, thermal evaporation, and the like.
In this case, since the metal deposition layer is directly deposited on the polymer film and the UV cured coating layer, the present invention is advantageous in not only the stereoscopic effect but also the color distortion phenomenon can be reduced.
It is preferable that the metal deposition layer has an OD (optical density) of 0.6 to 2.0. When the OD of the
Printing layer formation
In the print layer forming step S230, a print layer is formed on the metal vapor deposition layer. At this time, the print layer is partially printed on the upper surface of the metal deposition layer to display various designs, characters, and trademarks in various colors. In particular, the printing layer serves as a decoration layer using a metal bonding layer as a background.
In this step, the print layer may be formed using a multi-color gravure printing machine, which is operated at a printing frequency determined by a multi-gravure printing press. At this time, the printed layer is preferably formed to have a thickness of 1 to 3 mu m.
The interior sheets manufactured in the above steps S210 to S230 are three-dimensional and have a metal-like appearance effect by using a polymer sheet of a transparent material in place of heavy and difficult to handle glass, and are used as furniture, home electric appliance materials, Suitable.
In addition, the interior sheet produced by the above-mentioned method has transparency peculiar to glass, so that it is not only excellent in three-dimensional effect but also light in weight and excellent in handling and workability, and can be rolled into a roll shape. Therefore, there is an advantage in that productivity is good and manufacturing cost is low.
Therefore, the interior sheet manufactured by the method according to the embodiment of the present invention has a similar appearance effect as that of using glass, and is relatively light in weight compared to a glass product which must be fixed by a frame or made of silicone. Therefore, .
Meanwhile, although not shown in the drawings, the method of manufacturing an interior sheet according to an embodiment of the present invention may further include a hard coating layer forming step performed after the printing layer forming step.
In the hard coating layer forming step, a hard coating composition is applied to the other surface of the polymer film by a gravure coating method and dried to form a hard coating layer. At this time, the hard coat layer is formed for the purpose of improving antifouling property, impact resistance, scratch resistance and the like.
Such a hard coating layer may use at least one selected from acrylic, urethane, epoxy, and siloxane polymer materials, and an ultraviolet curable resin such as an oligomer may be used. In addition, the hard coating layer may further include a silica-based filler to improve the strength. At this time, the hard coat layer is preferably formed to a thickness of 1 to 10 mu m. If the thickness of the hard coat layer is less than 1 mu m, it may be difficult to exhibit the above effect properly. On the contrary, when the thickness of the hard coating layer exceeds 10 탆, there is a problem that the manufacturing cost increases compared to the effect increase, which is not economical.
As described above, when a hard coating layer is further formed after the printing layer forming step, a polymer sheet of a transparent material is used instead of a heavy and difficult-to-handle glass to have a three-dimensional appearance and a metal-like appearance effect, , Scratch resistance and the like can be improved.
