Description

Decorative material using gradient deposition and its manufacturing method {DECORATING MATERIAL FROM GLANCING ANGLE DEPOSITION AND METHOD OF MANUFACTRING THE SAME}

The present invention relates to a decorative material and a method of manufacturing the same, and more particularly, to provide a three-dimensional aesthetic by the difference in reflectance or transmittance between the cured resin and the metal on which the uneven pattern is formed, the metal layer by gradient deposition without using a mask It relates to a decorative material using a gradient deposition to improve the yield and process capability to form a and a method of manufacturing the same.

Decorative materials are used to decorate the living space beautifully and must be able to exhibit an aesthetic effect. Therefore, in order to beautifully decorate the exterior or interior of furniture, home appliances, electronics, etc., a synthetic resin decorative material and glass that are easy to process have been widely used.

In general, a synthetic resin decorative material is manufactured by flat printing a pattern on a synthetic resin sheet, a film, a panel, and the like, and applying a color effect to the transparent surface layer. Such a synthetic resin decorative material, due to the simple repetition of the flat pattern, the simplicity of the pattern color, etc., is insufficient to meet the aesthetic needs of the consumer.

In addition, conventionally, in order to improve such aesthetics, a single metal layer was deposited on the substrate on which the uneven pattern was formed to realize metallic aesthetics. However, when a single metal is deposited on the front surface, various textures and colors cannot be realized, and the same textures and colors can be felt even at different viewing angles.

Moreover, when the metal beauty is implemented with metal, its characteristics change according to the type and thickness of the metal. In other words, if the metal layer is too thin, the metal is inferior. If it is too thick, it is difficult to show a realistic metallic feeling by the effect of falling off or making the color in the pattern too dark.

There was also a tendency to deposit using shadow masks for partial deposition. When using such a shadow mask, there is a disadvantage in that it is difficult to align the metal layer at a predetermined position with respect to a very minute portion and a pattern portion.

Therefore, by implementing a variety of textures and colors that can not be produced by a single metal, it is possible to feel different textures and colors depending on the viewing angle and to provide a more three-dimensional aesthetic, without using a mask in the manufacturing process yield and process You need a way to improve your skills.

The present invention has been made to solve the above-described problem, an object of the present invention, by adjusting the angle of the sample at the time of deposition, by depositing a metal partly constant to use the difference in refractive, transmission, reflectance and intrinsic color difference Without the use of a separate mask and without increasing the thickness of the actual metallic and pattern three-dimensional effect is realized.

In order to solve the above-mentioned problems, the method of manufacturing a decorative material of the present invention forms a metal layer on a portion of the uneven pattern portion through oblique deposition, thereby producing a three-dimensional and various texture and color due to the difference in the refractive, transmissive and reflectance of light between the cured resin and the metal. The difference can be realized.

In addition, the inclination of the inclined deposition may be adjusted by tilting and adjusting the deposition equipment or the uneven pattern portion to match the working environment.

In particular, the gradient deposition can be quickly and reliably deposited in a vacuum using a plasma.

In addition, the uneven pattern portion is specifically (a) coating the cured resin on a mold having the uneven pattern; (b) pressing and contacting a polymer film with the cured resin; (c) curing the cured resin; And (d) removing the mold.

Here, the mold may be formed by embossing or engraving or a combination thereof to realize a three-dimensional effect with various patterns.

In particular, the cured resin may generate a hardened concave-convex pattern by irradiating ultraviolet light using an ultraviolet curable resin.

In addition, after the step (d), it may further comprise the step of forming a glass layer on the polymer film to prevent wear of the film.

According to the present invention, the constitution of the inclined deposition material includes an uneven pattern portion; And a metal layer formed on a portion of the uneven pattern portion.

In particular, the uneven pattern portion is formed of an embossed or intaglio or a combination thereof, and the metal layer is formed by at least one spaced apart from the neighboring metal layer, thereby reflecting to the metal which is not spaced apart from the light passing through the ultraviolet curable resin of the spaced apart portion. The light can be combined together to provide an excellent aesthetic.

In addition, the uneven pattern portion is formed using an ultraviolet curable resin, and further comprising a polymer film formed on the back surface of the uneven pattern portion of the ultraviolet curable resin can be utilized as a metal film that can be used from the outside.

In addition, it may further include a glass layer formed on the polymer film to prevent wear of the film.

By forming metal on part of hardened resin with irregularities pattern, various textures and colors can not be realized by single metal, so you can feel different textures and colors depending on the viewing angle, and reflectance between hardened resin and metals with irregularities pattern Due to the difference in transmittance, a three-dimensional aesthetic can be provided, and a metal layer can be formed by gradient deposition without using a mask in a manufacturing process to improve yield and processing capability.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the decorative material and the manufacturing method according to an embodiment of the present invention. In the description of the embodiments, the "on" and "under" of one side of the front film or the back film is formed to be "directly" or "indirectly" through other components. It includes everything. In addition, the criteria for the top or bottom of each component will be described with reference to the drawings. The size of each component in the drawings may be exaggerated for the sake of explanation and does not mean the size actually applied.

1 is a cross-sectional view of a decorative material in the form of a film according to an embodiment of the present invention.

1 includes a glass layer 110, adhesive layers 120 and 160, a polymer film 130, an ultraviolet curable resin 140, a metal deposition layer 150, and an adhesion surface 170.

Preferably, the glass film 110, the polymer film 140, or the adhesion surface 170 on which the metal deposition layer 150 is formed, and the adhesion surface 170 are adhered with a pressure sensitive adhesive (PSA).

In particular, the metal deposition layer 150 formed under the ultraviolet curable resin 140 is formed on a part of the surface where the uneven pattern of the ultraviolet curable resin 140 is formed.

As a result, when the light shines from above, the light passing through the glass layer 110, the adhesive layer 120, the polymer film 140 may be refracted, transmitted, and reflected in various paths.

More specifically, the light passes through the portion of the uneven pattern of the polymer film 140 where the metal deposition layer 150 is not formed, is reflected on the attachment surface 170, and is reflected back to the outside of the glass layer 110. It may be reflected by the attachment surface 170 and then reflected back to the metal deposition layer 150 several times to pass outside the glass layer 110.

In addition, the light emitted from the illumination may be reflected to the portion where the metal deposition layer 150 is formed in the uneven pattern of the polymer film 140 may be emitted to the outside of the glass layer 110.

As a result, light having various paths may be synthesized according to the angle and position viewed from the outside of the glass layer 110 to have a metal texture and provide a more three-dimensional aesthetic.

In particular, in order to specifically describe the effects of the aesthetics due to the refraction, transmission, and reflection, the results of measuring the color with a haze meter are shown in the table below.

Haze meter Wise Transmittance L a b Front deposition 89.26 9.55 30.91 2.61 -1.50 Gradient deposition 89.24 15.39 39.23 2.77 -0.45

Where L, a, b represent colors according to the Commission Internationale d'Eclairge (CIE). The fade is cloudy, the transmittance is transparent, and L is light and dark. a is in the range of green to red, closer to green as it goes to +, and closer to red as it goes to-, b is closer to blue as it goes to +, and closer to yellow as it goes to +.

As shown in Table 1, the phase is somewhat reduced, and the transmittance and brightness are increased compared to the front surface deposition. In addition, the color tends to be green as a increases from 2.61 to 2.77 and b tends to appear blue as b increases from -1.5. To -0.45.

This is because when the gradient deposition is performed, the portion where the metal deposition layer 150 is not formed has a large transmissive area, thereby increasing transmittance and changing color.

In addition, this decorative material can be used in the state without the glass layer 110. FIG. This means that it can be used as a decorative material in the form of a film. Therefore, R2R (Roll to Roll) process is possible and can be used for curved skin complexes.

2 is a flow chart of one embodiment of a preferred method of gradient deposition in accordance with the present invention.

The UV curable resin 220 is coated on the mold 210 having the uneven pattern, the polymer film 230 is pressed and adhered to the UV curable resin 220, and the ultraviolet curable resin 220 is cured by irradiating ultraviolet rays. After the mold 210 is removed. In addition, the UV curable resin 220 having the uneven pattern formed thereon and the metal deposition angle are maintained at a predetermined angle to be inclined.

Here, the deposition angle is defined as an acute angle formed between the normal line and the uneven pattern portion of the deposition apparatus. In addition, this deposition angle can be adjusted by tilting the deposition equipment or by tilting the uneven pattern portion. In this case, the gradient deposition preferably deposits the metal in plasma.

Subsequently, the polymer film 230 having the obliquely deposited ultraviolet curable resin 220 formed thereon is adhered to the attachment surface 260 to form a glass layer 270 on the polymer film 230. Here, it is preferable to use PSA for adhering to the attachment surface 260 and forming the glass layer 270.

3A and 3B illustrate a step for gradient deposition in more detail in the method of FIG. 2, and illustrates a state of gradient deposition of plasma while maintaining the metal deposition angle at a specific angle in a vacuum.

In addition, the metal targets shown in FIGS. 3A and 3B mean an object of a metal material for deposition. Here, in order to simplify the description, the deposition equipment for depositing the metal material is omitted, but it is preferable to understand that the metal target is mounted on the metal equipment and deposited.

3A shows a case of depositing a metal in a state in which the deposition angle is set to about 45 degrees by tilting the uneven pattern portion.

In this case, the metal layer is deposited in the direction in which the plasma is deposited in the uneven pattern portion, and the metal layer is not deposited in the other direction.

FIG. 3B illustrates a case where metal is deposited while the uneven pattern portion is inclined more sharply than that of FIG. 3A and the deposition angle is set to about 30 degrees. In this case, the metal is deposited in a smaller area than in FIG. 3A.

In the drawing, the deposition angle is shown in only one direction, but when tilted in a different direction, the deposition angle is deposited in the other direction as described above.

In addition, after gradient deposition, stainless series or the like may be deposited in the same vacuum to add reliability that the metal layer does not wear out.

As a result, since the area where the metal is deposited varies according to the deposition angle, various metal textures and colors can be realized by appropriately adjusting the deposition angle. In addition, the use of shadow masks for partial deposition can improve the efficiency of the process.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical spirit of the present invention should not be limited to the above-described embodiments of the present invention, but should be determined by the claims and equivalents thereof.
