Description

TECHNICAL FIELD [0001] The present invention relates to an interior film having a double-sided three-dimensional pattern using an imprinting method and a manufacturing method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior film on which a two-sided three-dimensional pattern is formed and a method of manufacturing the same, and more particularly, to a method of manufacturing an interior film on which a horizontal hairline is formed in a direction perpendicular to a longitudinal direction, And a method for manufacturing the interior film.

When metal materials such as aluminum, copper, and stainless steel are used as interior and exterior materials for buildings such as home appliances such as washing machines, refrigerators and air conditioners, and interior finishing materials for elevators, they are often used as a cool and luxurious feeling.

Especially, when the operator forms the hair line on the surface of the metal material by using the sandpaper or the nonwoven fabric, the specific luster of the metal is reduced, so that even if gas or the like is generated, the hairline is not noticeable. And the appearance is beautiful, so that a lot of metallic materials in which hair lines are formed on the inside and outside of home appliances and buildings are used.

However, attempts have been made to manufacture an interior film having an effect similar to that of a metal material to a plastic material having excellent workability and relatively low price due to a problem of physical properties such as high price, heavy weight, Has continued.

Conventionally, in order to produce an interior film having a texture of a metal material on which a hairline has been formed, a transparent ink is screen printed so as to have a hairline pattern on a transparent film (mainly using a PET film) (KR 10-2003-0087100 A), a hair line is formed directly on a transparent film using a sandpaper, a metal deposition layer is formed on the patterned film, and an adhesive After forming the layer, the inner film was laminated with the substrate film to prepare an interior film.

However, in the case of an interior film having a metal texture in which a hair line is implemented by a screen printing method using a transparent ink, the three-dimensional feeling and the metal material texture are lowered compared with the case where the hair line is formed directly on the transparent film, The interior film was prepared by forming a hair line directly on a transparent film and metallizing it.

On the other hand, in the case of forming the hair line on the transparent film itself as described above, the transparent film is passed through the roller wound with the sandpaper to induce physical scratches on the surface of the transparent film to form a hair line. When the hair line is formed on the transparent film itself as described above, the hair line in the direction parallel to the film longitudinal direction (that is, the longitudinal hair line formed in the direction in which the film is wound on the roll) is formed, Forming hair lines in one direction (that is, transverse hair lines formed in the film width direction) has a limited productivity, and has technical limitations in terms of metal hair-line texture implementation.

In addition, in the conventional interior film, a pattern such as a hair line is formed only on one side, so that there are limitations in realizing various patterns with more three-dimensional feeling.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an interior film on which a double-sided three-dimensional pattern of the present invention is implemented and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.

1 is a view showing a first embodiment of an interior film (F) in which a double-sided solid pattern of the present invention is embodied. Specifically,

A transparent film layer 130;

A first imprinting layer 120 embodying a surface three-dimensional pattern 121 formed on the transparent film layer 130;

A second imprinting layer 140 embodying a transverse hairline 141 formed under the transparent film layer 130;

And a metal deposition layer 150 formed on the lower portion of the second imprinting layer 140. As shown in FIG.

Further, the interior film (F) in which the above-described two-sided solid pattern is implemented is produced by the following manufacturing method. Specifically,

Applying an ultraviolet curable resin composition on one side of the transparent film layer 130;

The ultraviolet curable resin composition applied on the transparent film layer 130 is imprinted with a first shaping roller R having a transverse hairline H formed thereon and ultraviolet cured to form the transverse hairline 141 Forming a second imprinting layer (140);

Applying an ultraviolet curable resin composition to the other surface of the transparent film layer 130;

A first imprinting layer 120 embodying a surface three-dimensional pattern 121 is formed by imprinting the ultraviolet-curable resin composition coated on the transparent film layer 130 with a second forming roller having a three-dimensional pattern formed thereon, ;

And forming a metal deposition layer 150 under the second imprinting layer 140. The two-sided three-dimensional pattern is formed by a method of manufacturing an interior film.

In the method for manufacturing the interior film (F) in which the double-sided solid pattern of the present invention is implemented, the upper and lower sections are based on the finished product. For example, the metal deposition layer 150 may be formed under the second imprinting layer 140. The metal deposition layer 150 may be formed under the second imprinting layer 140 on the basis of the finished film. The metal deposition layer 150 may be formed on the second imprinting layer 140 with the upper and lower sides of the film turned upside down according to the convenience of the operator. It is.

In the present invention, the transparent film layer 130 may be formed of a material selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), poly methyl methacrylate (PMMA) -butadiene-styrene, PC (polycarbonate), and SAN (styrene-acrylonitrile copolymer) films. The use of a transparent PET film, preferably thin, uniform and transparent, is advantageous because of the lateral hairline embodied in the second imprinting layer 140 and the metal deposition layer 150 formed therebelow, It can be expressed more clearly.

The thickness of the transparent film layer 130 is 20 to 200 占 퐉. When the thickness of the transparent film layer 130 is less than 20 탆, the second imprinting layer 140 formed below the transparent film layer 130 may not be supported and may be damaged. When the thickness is more than 200 탆, It is preferable that the first imprinting layer 120 has a thickness in the above range since the first imprinting layer 120 may cause hardening and deterioration of adhesion. More preferably, a film having a thickness of 20 to 50 mu m is most preferably used.

In addition, it is preferable that the transparent film layer 130 has a primer layer (first and second primer layers 131 and 132) formed on one side or both sides thereof so as to have an excellent adhesive strength when adhered to other layers.

In the interior film (F) having the double-sided solid pattern of the present invention, a second imprinting layer 140 having a transverse hairline 141 is formed under the transparent film layer 130.

The second imprinting layer 140 is formed by imprinting the ultraviolet curable resin composition coated on the transparent film layer 130 with a first shaping roller R having a transverse hairline H, , And a transverse hairline formed on the first shaping roller (R) is formed on the transparent film layer (130) coated with the ultraviolet curable resin composition.

More specifically, when UV is applied after passing the transparent film layer 130 coated with the ultraviolet-curable resin composition between the first forming roller R and the steel roller R-1, R may be cured in the state of being imprinted on the ultraviolet ray hardening type resin composition to form the second imprinting layer 140 in which the transverse hair line 141 is implemented 4).

The ultraviolet curable resin composition includes an acrylate oligomer, a monomer, a photoinitiator, and other additives that complement the physical properties.

The acrylic oligomer may be one selected from the group consisting of urethane, epoxy, ester, ether and silicone. It is preferable to use a polyurethane acrylate prepared by reacting a diisocyanate, a polyol and a methacrylate.

The photoinitiator may be a conventional photoinitiator such as Irgacure 184 or a light stabilizer such as Tinuvin 400.

The ultraviolet ray hardening type resin composition may be a resin composition having a solid content of 30 to 100% by weight. Preferably, a solvent is added in order to realize the same hair line as the lateral hair line formed parallel to the longitudinal direction of the forming roller It is preferable to use a resin composition having a solid content of 100% by weight.

The coating thickness of the ultraviolet-curable resin composition is preferably such that the thickness of the second imprinting layer 140 in a cured state is 2 to 80 占 퐉. When the thickness is less than 2 mu m, it is difficult to realize the lateral hair line. When the thickness exceeds 80 mu m, the hardness is high and cracks are generated .

The transverse hairline 141 embodied in the second imprinting layer 140 preferably has an average roughness Ra of 0.1 to 10 탆 and an elongation per unit length of 1 cm of 20 to 350, Ra) of 0.2 to 0.7 占 퐉, and an elongation per unit length of 1 cm is preferably 80 to 140.

When the average roughness is less than 0.1 탆, it is difficult to enjoy the effect of the appearance of the light due to irregular reflection. When the average roughness exceeds 10 탆, rough roughness is obtained, It is preferable that the average roughness is in the above range. More preferably, when the average roughness is 0.2 to 0.7 탆, the most natural, smooth, and beautiful appearance effect can be obtained.

In addition, the number of lines per 1 cm of the unit length is the number of lines of the transverse hair line passing through a 1 cm-long line parallel to the longitudinal direction of the interlayer film. If the number of the players is less than 20, And if the number of the athletes exceeds 350, the beauty of the appearance may be deteriorated due to an excessive number of athletes. More preferably, the ratio of 80 to 140 per 1 cm of the unit length is most natural, and an effect of a beautiful appearance can be obtained.

In the present invention, the transverse hairline can have various lengths without limitation of length.

The transverse hairline of the present invention has an average roughness (Ra) of 0.1 to 10 mu m Such an interior film in which the transverse hairline is implemented can produce the closest appearance to the hairline formed on the actual metal surface that can not implement any conventional interior film.

In the interior film (F) having the double-sided solid pattern of the present invention, a first imprinting layer 120 having a surface stereoscopic pattern 121 is formed on the transparent film layer 130.

Meanwhile, the process of forming the first imprinting layer 120 and the second imprinting layer 140 is a continuous process in-line. That is, after the second imprinting layer 140 is formed on the upper surface of the transparent film layer 130, the transparent film layer 130 is turned over and the ultraviolet curable resin composition is coated on the second imprinting layer 130, When the transparent film layer 130 is passed between the forming roller and the steel roller and UV is irradiated, the three-dimensional pattern formed on the second forming roller is cured in the state of being imprinted on the ultraviolet-curable resin composition as it is, The first imprinting layer 120 may be formed. Here, the surface three-dimensional pattern 121 may be a circular or polygonal pattern, a cylindrical or polygonal pattern, a grid pattern, a striped pattern, a dot pattern, a mosaic pattern, a dobby pattern, a plant pattern such as a flower pattern, , A 3D stereoscopic pattern, and the like, or a combination pattern of these stereoscopic patterns.

The three-dimensional pattern may be formed at a depth of 2-50 mu m. Outside this range, the diffused reflection effect may be deteriorated.

The ultraviolet curable resin composition of the first imprinting layer 120 may be the same as the ultraviolet curable resin composition used in the second imprinting layer 140 or may further include a pigment for UV resin to add a color effect thereto.

The pigments may be conventional pigments such as, for example, self-dispersed pigments, polymer-coated pigments, or ground pigments. A separate dispersant may be used to appropriately suspend the pigment in the ultraviolet-curable resin composition. The particulate pigment may be an inorganic or organic pigment. The pigments may be spot colors obtained from certain colors including black, blue, brown, cyan, green, white, purple, magenta, red, orange and yellow as well as mixtures thereof. Examples of organic pigments include, but are not limited to, perylene, phthalocyanine pigments (e.g., phthalocyanine, phthaloyl), cyanine pigments (Cy3, Cy5, and Cy7), naphthalocyanine pigments, nitroso pigments, Azo pigments, mono-azo pigments, di-azo pigments, di-azo condensed pigments, basic dye pigments, alkali blue pigments, blue lake pigments, proxine pigments, quinacridone pigments, isoindolinone pigments, Indigo pigments, anthraquinone pigments, and quinophthalone pigments, and pigments such as azo pigments such as azodi-y-y photophilic pigments, alizarin lake pigments, phthaloxyamine pigments, camine lake pigments, tetrachloroisoindolinone pigments, And mixtures of two or more of these pigments and derivatives of the pigments. The inorganic pigments that may be present in the ultraviolet-curable resin composition include, for example, metal oxides (such as titanium dioxide, electrically conductive titanium dioxide, iron oxide (for example, red iron oxide, yellow iron oxide, black iron oxide, , Aluminum oxide, silicon oxide), carbon black pigments (e.g., furnace black), metal sulfides, metal chlorides, and mixtures of two or more thereof.

In the interior film (F) in which the double-sided solid pattern of the present invention is implemented, a metal deposition layer (150) is formed under the second imprinting layer (140).

The metal deposition layer 150 may be formed by depositing a metal selected from aluminum, chromium, zinc, copper, stainless steel, gold, silver, nickel, cobalt, iron, tin, As shown in FIG.

The metal deposition layer 150 may be formed by a general vacuum thermal deposition method, a sputtering method, or the like. For example, in the case of the vacuum thermal deposition method, vacuum deposition can be performed at 10 ^-4 to 10 ^-6 torr and 300 to 800 ° C. In the case of the sputtering method, the second imprinting layer 140, the metal nanoparticles may be coated on the lower layer to perform the metal deposition, but the deposition method is not particularly limited. The metal may be one selected from the group consisting of aluminum, chromium, zinc, copper, stainless steel, gold, silver, nickel, cobalt, iron, tin and stain, . Those skilled in the art can select the appropriate metal according to the metal texture to be formed to form the metal deposition layer 150 of the present invention.

The metal deposition layer 150 is preferably formed to a thickness of 100 to 1,000 angstroms. When the thickness of the metal deposition layer 150 is less than 100 angstroms, it is difficult to detect the metallic feeling outside the transparent film layer 130. When the thickness of the metal deposition layer 150 exceeds 1000 angstroms, cracks may occur, It is preferable that the thickness is within the above range.

In addition, the metal deposition layer 150 may be a single metal deposition layer or a multi-layered metal deposition layer.

The metal deposition layer 150 of the present invention is sensed from the outside through the first imprinting layer 120, the transparent film layer 130 and the second imprinting layer 140, And a color similar to that of a metal can be expressed.

Alternatively, the metal deposition layer 150 may be replaced with a perl coating layer 151 or a print layer 152 (see FIGS. 2 and 3).

2 is a view showing an interior film on which a two-sided solid pattern is formed by applying a perl coating layer 151 instead of the metal vapor deposition layer 150. FIG. Fig. 3 is a view showing an interior film embodying the present invention.

The perl coating layer 151 uses a pearl pigment and can have a luster effect like a metal. Although it is preferable to use calcium aluminum borosilicate-based pigment as the pearl pigment, it is not limited thereto.

The printing layer 152 can be formed by various printing methods such as gravure printing, screen printing, and the like using various color pigments, thereby improving the utilization of the interior film.

In the interior film on which the double-sided solid pattern of the present invention is implemented, an adhesive layer 160 may be further formed under the metal deposition layer 150.

The adhesive layer 160 may be formed by a coating method such as a comma coating with a polyurethane, polyester or epoxy adhesive, and the thickness thereof is 1 to 20 탆, preferably 1 to 10 탆, more preferably 5 Mu] m to 10 [mu] m. In addition, when the adhesive layer 160 is formed of an opaque layer, it is possible to produce a clearer three-dimensional effect, so that a pigment may be added to the adhesive.

The interior film on which the double-sided three-dimensional pattern of the present invention is implemented may optionally further include a base layer 170 under the adhesive layer 160.

The base layer 170 protects the metal deposition layer 150 and is made of polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), acrylonitrile-butadiene -styrene, PC (polycarbonate), SAN (styrene-acrylonitrile copolymer) and PMMA (polymethylmethacrylate). The thickness of the base layer 170 is preferably 30 to 300 mu m.

If the coloring film of the material is used for the base layer 170, even if the state of the iron plate surface is somewhat uneven, the appearance quality is excellent without the orange peel after iron plate lamination.

In addition, the interior film on which the double-sided solid pattern of the present invention is implemented may be further provided with a release paper 180 coated with an adhesive under the base material layer 170. It is preferable that the adhesive is a hot-melt type adhesive which is adhered by the heat and pressure.

In addition, the interior film on which the double-sided three-dimensional pattern of the present invention is implemented may optionally have a surface coating layer 110 selectively formed on the first imprinting layer 120.

The surface coating layer 110 protects the surface of the film from the external environment to prevent surface scratches and contamination. The surface coating layer 110 is formed by UV curing or thermosetting after coating with an ultraviolet curable resin composition or a thermosetting resin composition by a gravure coating method can do.

Examples of the ultraviolet ray curable resin composition or thermosetting resin composition include acrylic, acrylic urethane, epoxy, polyurethane, polyisocyanate, polyester, acrylate, ethylene-vinyl acetate copolymer, polyamide, melamine, Rubber-based, polyvinyl alcohol-based resin and the like can be used, and it is preferable to further include an inorganic filler to improve strength and mechanical properties.

The thickness of the surface coating layer 110 is preferably 1 to 30 탆. If the thickness is less than 1 mu m, the effect of preventing scratches is insignificant. If the thickness is more than 30 mu m, a problem of increase in cost may be caused as compared with the effect.

In addition, the interior film F having the double-sided solid pattern of the present invention may be further formed with a third primer layer 153 between the second imprinting layer 140 and the metal deposition layer 150 .

The first primer layer 131 and the second primer layer 132 may be formed on the upper and lower portions of the transparent film layer 130 and the third primer layer 153 may be formed on the second imprinting layer 130. [ May be formed under the layer 140. When the primer layer is formed, the adhesion between the layers contacting with the primer layer can be enhanced, which is preferable.

As the primer for forming the primer layer, an acrylic type, an acrylic urethane type or an epoxy type resin can be used, and it is more preferable to use an aliphatic urethane acrylate. The thickness of the first primer layer 131, the second primer layer 132, or the third primer layer 153 is preferably 1 to 10 탆.

In the meantime, the lateral hairline formed on the surface of the first forming roller R used in the method of manufacturing an interior film having the three-dimensional pattern on both sides of the present invention is composed of minute hairline lines, (See FIG. 6), the first shaping roller R is formed so as to be perpendicular to the longitudinal direction of the film when the transparent film layer 130 coated with the UV-curable resin composition passes through the first shaping roller R So that the hairline is formed. The lateral hair lines of the first shaping roller R have various line lengths and have an average roughness Ra of 0.1 to 10 mu m and a length of 20 to 350 per 1 cm of the unit length L and are preferably randomly arranged Do.
