Description

Technology Field

[0001] The present invention relates to a metal texture flooring having a natural metal texture, comprising a substrate layer, a transparent pearl film layer, a printing layer, and a surface film layer. Background Technology

[0002] With the recent advancement of color mixing technology and the improvement of consumers' standards for color and aesthetics, design products featuring diverse aesthetics capable of satisfying consumer demands are being released.

[0003] Among them, consumer interest and demand for interior materials such as wallpaper, flooring, and ceiling finishes, which are significantly influenced by design elements, are on the rise.

[0004] On the other hand, in the case of flooring materials, since they involve not only design elements but also actual friction and use, such as users stepping on them or placing objects, there was a limitation in that they had to enhance aesthetics while satisfying the required functions of flooring.

[0005] Accordingly, the actual material, such as wood texture flooring, metal texture flooring, and marble texture flooring, is composed of a resin-based flooring layer, and by imparting natural design patterns and colors to its surface, it is configured to enhance the aesthetic appeal of the flooring while satisfying physical properties required for flooring, such as durability, impact resistance, and scratch resistance.

[0006] In the case of metal texture flooring, we attempted to manufacture flooring with a natural metal texture by printing materials such as metal powder and metal pearls to achieve a more natural metal texture. However, when materials such as metal powder or metal pearls were used in amounts exceeding a certain level in the printed layer, they reduced the adhesion to adjacent layers, causing delamination between layers.

[0007] Korean Registered Patent No. 0467227 discloses only the composition of a synthetic resin tile flooring that includes metal pearls in the printing layer to form a metallic texture, but does not specifically disclose the problem of securing the durability of the flooring while increasing the amount of metal pearls used to form a more natural metallic texture, and the method of solving the same.

[0008] On the other hand, if the upper surface of the flooring exhibits uniform gloss and reflection effects, it is difficult to achieve a natural metallic texture, and there is a problem in that it creates artificial visual effects that actually detract from the aesthetic appeal of the flooring. Since metal generally exhibits reflection effects in different regions depending on the direction of light, it is necessary to configure the gloss and reflection effects differently across the surface area to achieve a natural metallic texture.

[0009] In this regard, Korean Registered Utility Model No. 0299621 relates to a flooring material with a synchronized three-dimensional texture having excellent diffuse reflection effects. It discloses a flooring material with a synchronized three-dimensional texture having a structure in which a lower foam layer, a glass fiber mat impregnated layer containing a glass fiber mat and PVC resin, an upper foam layer, a pearl sheet layer, a suppressing printing layer, and a transparent layer are sequentially laminated. However, it does not disclose a technology that allows different reflection and gloss effects to be exhibited depending on the area in order to realize a more natural metallic texture on the surface of the flooring material.

[0010] After numerous experiments and repetitions, the inventors of the present invention have succeeded in completing a metal-textured flooring material and a method for manufacturing the same, which improves aesthetics by realizing a natural metal texture while ensuring excellent durability by preventing delamination of the flooring layer. Prior art literature

[0011] Republic of Korea Registered Patent No. 0467227 (January 24, 2005) Republic of Korea Registered Utility Model No. 0299621 (January 3, 2003) The problem to be solved

[0012] The present invention relates to a metal-textured flooring material and aims to provide a novel metal-textured flooring material and a method for manufacturing the same, which can prevent peeling of the flooring material while increasing the amount of metallic pearl used to achieve a natural metal texture.

[0013] The present invention aims to provide a metal texture flooring material and a method for manufacturing the same, wherein the gloss and reflection effects on the surface of the flooring material appear differently depending on the area, thereby realizing a more natural metal texture. means of solving the problem

[0014] A metal texture flooring material according to the present invention for solving the above-mentioned problems comprises a substrate layer, a transparent pearl film layer, a printing layer, and a surface film layer, wherein the transparent pearl film layer comprises a pearl pigment.

[0015] In the present invention, the transparent pearl film layer may contain 0.5 to 5 weight percent of pearl pigment based on the total weight of the transparent pearl film layer.

[0016] In the present invention, the transparent pearl film layer may have a thickness of 0.05 to 0.4 mm.

[0017] In the present invention, the transparent pearl film layer may include PVC resin and metallic pearl pigment.

[0018] In the present invention, the metal texture flooring may further include a concealing ink layer between the transparent pearl film layer and the printing layer.

[0019] More specifically, the above-mentioned concealing ink layer may include one or more selected from the group consisting of titanium dioxide, zinc oxide, and carbonite.

[0020] In the present invention, the metal texture flooring may have a light reflectance of 40 to 80% in the visible light region.

[0021] A method for manufacturing a metal-textured flooring material according to the present invention comprises: a) forming a transparent pearl film layer on the surface of a substrate layer; b) forming a printed layer on the surface of the transparent pearl film layer formed in step a); and c) forming a surface film layer on the surface of the printed layer formed in step b).

[0022] More specifically, the method may further include a step of forming a concealing ink layer after step a) and before step b). Effects of the invention

[0023] The present invention can increase the metallic pearl content compared to existing metallic texture flooring, thereby providing an improved metallic texture effect.

[0024] The present invention contains an excessive amount of metallic pearl compared to existing technology, while preventing the problem of flooring layers separating from each other, that is, peeling from the printing layer where the metallic pearl is printed, thereby providing the effect of excellent durability of the flooring.

[0025] The metal texture flooring according to the present invention has the effect of exhibiting a more natural metal texture by having different gloss and reflection effects of metallic pearls on the surface of the flooring depending on the area due to a printing layer containing a concealing ink layer and a color ink.

[0026] The present invention also provides a method for manufacturing a metal-textured flooring material that utilizes existing equipment without the need for additional equipment, as the process is performed in a manner similar to existing technologies such as printing and lamination processes. Brief explanation of the drawing

[0027] FIG. 1 is a schematic diagram showing the structure of a metal-textured flooring material according to one embodiment of the present invention; FIG. 2 is a photograph of a metal-textured flooring material according to one embodiment of the present invention; FIG. 3 is a photograph of a metal-textured flooring material according to another embodiment of the present invention; Figure 4 is a photograph of a metal-textured flooring material according to another embodiment of the present invention. Specific details for implementing the invention

[0028] Hereinafter, each component of the present invention is described in more detail so that a person skilled in the art to which the present invention pertains can easily implement it; however, this is merely an example, and the scope of the rights of the present invention is not limited by the following.

[0029] The metal texture flooring material according to the present invention comprises a substrate layer, a transparent pearl film layer, a printing layer, and a surface film layer, and each layer has a structure in which layers are sequentially laminated from the bottom surface, and the transparent pearl film layer comprises a pearl pigment.

[0030] In the present invention, in conventional metal texture flooring, it was necessary to increase the amount of metallic pearl in the printing layer to improve the metal texture effect, but when the amount of metallic pearl in the printing layer increased, the adhesion between the printing layer and the adjacent layer decreased, causing the upper layer and the lower layer of the printing layer to separate from each other.

[0031] The present invention is an invention for solving the problem of reduced adhesion of the printing layer while increasing the amount of metallic pearl used. The present invention is characterized by introducing a transparent pearl sheet containing metallic pearl on the lower part of the printing layer to provide the same effect as printing with metallic pearl on a metallic pearl printing layer, while increasing the amount of metallic pearl used to provide an even more enhanced metallic texture effect.

[0032] FIG. 1 is a schematic diagram showing the structure of a metal texture flooring according to one embodiment of the present invention.

[0033] Referring to FIG. 1, a metal texture flooring material is disclosed, comprising a base layer, a transparent pearl film layer (metal pearl film), a high-opacity white ink layer, a printing layer, and a transparent film layer on the surface from the bottom surface.

[0034] As an example, a more natural metallic texture can be achieved by configuring the system to either omit or include a high-opacity white ink layer as needed.

[0035] The composition is explained in more detail below.

[0036] Transparent pearl film layer

[0037] The metal texture flooring according to the present invention is characterized by comprising a transparent pearl film layer containing a spreading pigment, in contrast to conventional flooring.

[0038] The above transparent pearl film layer is located on the upper part of the substrate layer and on the lower part of the printing layer, forming a printing layer on the upper part of the transparent pearl film layer to impart a metallic effect with a desired design.

[0039] Specifically, the transparent pearl film layer is characterized by containing 0.5 to 5 weight percent of pearl pigment based on the total weight of the film layer. Preferably, it may contain 0.65 weight percent or more.

[0040] If included in a small amount less than the above content, there is a problem that the difference in metallic texture effect compared to existing metallic texture flooring is negligible, and if included in an excessive amount more than the above content, the viscosity of the mixed composition for forming the transparent pearl film layer increases, making it difficult to implement in the form of a film or causing a decrease in adhesion to other layers.

[0041] Meanwhile, the thickness of the transparent pearl film layer may be 0.05 to 0.4 mm. Preferably, it may be 0.1 to 0.3 mm. By configuring within the above thickness range, design effects by pearl can be achieved while minimizing problems such as reduced balance, which are issues arising from the addition of an additional layer within the flooring material.

[0042] If the thickness is thinner than the above, there is a problem that the pearl pigment is difficult to disperse uniformly in the transparent pearl film layer, and there may be a problem that the difference in metallic texture effect is not significant relative to the amount of pearl pigment used.

[0043] If the thickness is greater than the above thickness, the thickness of the base layer becomes relatively thin to meet the general thickness specifications of the flooring material, which may lead to a decrease in the support performance of the flooring material and cause a deterioration in the quality of the flooring material itself.

[0044] The pearl pigment included in the transparent pearl film layer above may preferably be a metallic pearl pigment.

[0045] More specifically, the metallic pearl pigment may be one selected from the group consisting of gold pearl pigment, silver pearl pigment, copper pearl pigment, chrome pearl pigment, brass pearl pigment, and mixtures thereof.

[0046] The above metallic pearl pigment can be configured to include a metallic pearl pigment mixture appropriately according to the desired effect.

[0047] Meanwhile, the transparent pearl film layer comprises PVC resin in addition to pearl pigment. Since PVC resin has excellent durability, is easy to process into a film form, and is easy to form into a transparent film layer, the transparent pearl film layer is manufactured using PVC resin.

[0048] The above transparent pearl film layer may further include various additives, such as plasticizers and processing aids, as needed. These can be appropriately added as needed to control the physical properties of the transparent pearl film layer.

[0049] FIG. 2 is a photograph of a metal texture flooring material according to one embodiment of the present invention, FIG. 2 is a photograph of a flooring material composed of a substrate layer, a transparent pearl film layer, a printing layer, and a surface protection layer.

[0050] Compared to conventional metal texture flooring, by configuring the transparent pearl film layer to include metallic pearl pigment, the metal texture effect is further enhanced, and the durability of the flooring is good or excellent.

[0051] material layer

[0052] The above-mentioned substrate layer is intended to function as a flooring material and serves to support a transparent pearl film layer, a printed layer, etc. located on top of it.

[0053] The above-mentioned substrate layer supports the upper layer and can be used without special restrictions as long as it functions as a flooring material, and can be configured differently depending on the shape and characteristics of the flooring material.

[0054] Flooring materials include sheet-type flooring, commonly referred to as linoleum, and tile-type flooring; in the present invention, various substrate layers can be used depending on the type of flooring material.

[0055] Specifically, the above substrate layer may include one or more resins selected from the group consisting of PET resin, PVC resin, acrylic resin, urethane resin, etc., and preferably may be configured to include PET resin.

[0056] The thickness of the above-mentioned substrate layer is not particularly limited, and any layer that satisfies the basic characteristics required for flooring can be used.

[0057] Printed layer

[0058] A printing layer is formed on the upper surface of the above transparent pearl film. The printing layer is intended to provide an aesthetic sense by giving color and design to the flooring material, and various color inks can be printed in a specific pattern or on the entire surface.

[0059] The printing method of the above-mentioned printing layer is not particularly limited and various methods can be used, but more specifically, the above-mentioned color ink can be printed by using a gravure printing method. The above-mentioned color ink can achieve various colors by using CMYK ink.

[0060] In the prior art, a metallic texture was imparted by including pearl pigments in the printing layer to achieve a metallic texture on the surface of the flooring material. However, when the amount of pearl pigments, particularly metallic pearl pigments, was excessive, the adhesion between the upper and lower layers of the printing layer decreased, which caused a problem of reduced durability of the flooring material.

[0061] However, in the present invention, by configuring the transparent pearl printing layer to include a metallic pearl pigment for imparting a metallic texture to the flooring material, it is possible to achieve an enhanced metallic texture effect even if the printing layer does not include a pearl pigment or if only a limited amount is used to ensure the durability of the flooring material.

[0062] Accordingly, the printing layer according to the present invention can be formed to include not only color ink but also, if necessary, additional pearl pigment, and in particular, can be printed to include metallic pearl pigment.

[0063] However, it is preferable that the content of the pearl pigment included in the above-mentioned printing layer be used in a limited amount to prevent peeling of the layer constituting the flooring material.

[0064] For example, in addition to the transparent pearl printing layer, when printing with a pearl pigment included in the printing layer, the pearl pigment may be configured to be included in an amount of 5 weight percent or less based on the total weight of the printing layer.

[0065] Meanwhile, the printing ink composition for forming the above-mentioned printing layer includes an acrylic resin and a color ink.

[0066] By configuring it to include an acrylic resin, it is configured to maintain excellent adhesion of the printed layer.

[0067] As described above, if the content of the pearl pigment in the printing layer exceeds the above content, there is a problem in that the durability of the flooring material is reduced due to peeling of the printing layer.

[0068] The above printing layer can express a more natural metallic texture by adding pearl pigments to the transparent pearl film layer and painting with various colored inks on top thereof to express rusted metal or induce natural scratches or discoloration such as wear and tear.

[0069] FIG. 4 is a photograph of a metal texture flooring material according to another embodiment of the present invention, comprising a substrate layer, a transparent pearl film layer, a printing layer, and a surface protection layer, wherein a dark-colored ink is used in the printing layer to naturally create a rusted metal effect.

[0070] In this way, a more natural metallic texture can be achieved by including a transparent pearl film layer and utilizing various colors in the printing layer located on top thereof.

[0071] opaque ink layer

[0072] The metal texture flooring material according to the present invention comprises a substrate layer, a transparent pearl film layer, a printing layer, and a surface protection layer, and may further comprise a concealing ink layer between the transparent pearl film layer and the printing layer.

[0073] The above-mentioned opaque ink layer is configured to more naturally realize a metallic texture by using an opaque white pigment that prevents the image or color of the lower layer from being exposed to the top, and by controlling the dispersion and concentration of the opaque white pigment.

[0074] The above-mentioned opaque ink layer can be used with any pigment or ink component having opaque power without particular limitation, and may include, for example, one or more selected from the group consisting of titanium dioxide, zinc oxide, and carbonite, and preferably may include titanium dioxide.

[0075] In addition, the above-mentioned opaque ink layer may also be formed using a polymer resin having opaque power. For example, MEK-based medium resin, PVC-based medium resin, etc. may be used. However, this is merely one example, and various configurations may be utilized within the scope that satisfies the purpose and effects of the present invention.

[0076] The above-mentioned concealing ink layer may be included with a thickness of 20 μm (micrometer) or less, preferably with a thickness of 10 μm (micrometer) or less, and may be included with a thickness of 5 μm (micrometer) or less.

[0077] If the thickness is greater than the above, the pearl pigment of the transparent pearl film layer located below the opaque ink layer may not be easily observed on the surface of the flooring material, which may result in a decrease in the metallic texture effect.

[0078] Meanwhile, the above-mentioned opaque ink layer may include PVC resin and may include 1 to 15 parts by weight of an opaque white pigment per 100 parts by weight of PVC resin.

[0079] For example, 5 to 10 parts by weight of titanium dioxide and 3 to 7 parts by weight of carbonite may be added within the above weight range.

[0080] Preferably, the above-mentioned opaque white pigment may be included in an amount of 5 to 10 parts by weight, wherein the above-mentioned opaque white pigment may be titanium dioxide.

[0081] When added in excess of the above amount, the pearls of the transparent pearl film layer are not observed, making it difficult to achieve a metallic texture.

[0082] In particular, the above-mentioned opaque ink layer has the effect of creating a more natural metallic texture by configuring the reflection and gloss effects of the pearl pigment observed on the surface of the flooring material differently in each area.

[0083] Specifically, the pearl pigment dispersed in the transparent pearl film layer and the opaque white pigment dispersed in the opaque ink layer combine to provide various reflection and gloss effects in each area.

[0084] FIG. 3 is a photograph of a metal texture flooring material according to another embodiment of the present invention, comprising a substrate layer, a transparent pearl film layer, a opaque ink layer, a printing layer, and a surface protection layer.

[0085] Referring to Fig. 3, compared to Fig. 1, the reflection and gloss effects in various areas of the flooring surface appear naturally, thereby realizing a natural metallic texture.

[0086] surface film layer

[0087] A surface film layer is laminated on the surface of the above-mentioned printing layer, and the surface film layer serves to maintain the transparent pearl film layer and the printing layer of the flooring material so that they can be observed transparently while maintaining the aesthetic appeal and preventing damage to the printing layer of the flooring material.

[0088] Accordingly, it is preferable to use a material that is transparent while having scratch resistance for the surface film layer.

[0089] The lamination method thereof is not particularly limited and can be used, and the mixture constituting the surface film layer can be coated by various methods such as blade coating, brush coating, spray coating, etc.

[0090] The metal texture flooring according to the present invention, comprising the above-described composition, can achieve a more natural metal texture compared to conventional metal texture flooring.

[0091] Specifically, as an appearance effect that could not be achieved with the limited amount of conventional metallic pearl pigments, it features a light reflectance value (LRV) of 40 to 80% in the visible light region, thereby realizing a natural metallic texture. Preferably, the reflectance value may be 50 to 70%.

[0092] If the reflectance is higher than the above range, the light reflected from the flooring material appears bright from the observer's perspective, resulting in a loss of natural metallic texture; if the reflectance is lower than the above range, the reflection effect is negligible, failing to match the luster of the metal itself. Therefore, by reflecting within the above range, a natural metallic texture is achieved.

[0093] Meanwhile, if the reflectance of the light is lower than the above range, the gloss effect of the metal itself cannot be sufficiently realized, and the metallic texture effect may be perceived as insignificant; and if it is higher than the above range, there is a problem in that the reflection effect is excessive and it may be observed as an artificial metallic texture.

[0094] Method for manufacturing metal-textured flooring

[0095] The present invention also provides a method for manufacturing the metal texture flooring described above.

[0096] Specifically, the method for manufacturing a metal texture flooring according to the present invention comprises: a) forming a transparent pearl film layer on the surface of a substrate layer; b) forming a printed layer on the surface of the transparent pearl film layer formed in step a); and c) forming a surface film layer on the surface of the printed layer formed in step b).

[0097] In the metal texture flooring according to the present invention, for a detailed description of each component, refer to the description of the components described above.

[0098] Meanwhile, by further including the step of forming a concealing ink layer after step a) and before step b), a flooring material further comprising a concealing ink layer according to one embodiment of the present invention can be manufactured.

[0099] In the case of the manufacturing process of conventional metal-textured flooring, the process involves sequentially forming a printing layer on the surface of a substrate layer, printing a pearl pigment, and then forming a surface protection layer. However, in the case of the present invention, the method is similar to the conventional method, but can be manufactured by further including the step of forming a transparent pearl film layer on the surface of a substrate layer and, if necessary, forming an additional opaque ink layer on the surface.

[0100] The above transparent pearl film layer can be introduced to be laminated on top of a substrate layer by unwinding the film in a roll-to-roll process and laminating it, just like a PVC film, and the above opaque ink layer can be formed using a printing technique that forms a printed layer. For example, when using gravure printing to form a printed layer, the process can be performed by first forming an opaque ink layer by configuring the opaque ink as one color, and then gravure printing with color ink on the surface thereof.

[0101] As such, the metal-textured flooring material and the method for manufacturing the same according to the present invention have the advantage of high manufacturing efficiency and the ability to be manufactured using existing equipment, in that there is no significant difference in the structural aspect of the flooring material compared to existing technology and the manufacturing process is not significantly different.

[0102] [Preparation Example]

[0103] Flooring was manufactured by referring to Table 1 below.

[0105] [Flooring Material Properties Evaluation]

[0106] 1. Measurement of peel strength between the printed layer and the surface film layer

[0107] A flooring material was prepared as a specimen with a width of 2.54 cm (1 inch) and a length of 15 cm, and a substrate including a transparent pearl film layer and a substrate layer was attached to the moving part of the high-speed peeler in the horizontal direction using a high-speed peeler (ChemInstruments, AR-1000). The surface film layer was fixed to a clamp of the fixed part equipped with a sensor capable of measuring strength, and the strength applied to both parts of the surface film layer and the substrate layer was measured over time while moving the moving part in the horizontal direction at a speed of 300 cm / min. The average value of the measured peel strength was calculated and is shown in Table 2.

[0108] 2. Evaluation of Flooring Surface Properties

[0109] After irradiating the surface of the flooring specimen with light in the visible light range (400 to 700 nm), the reflectance was measured using a reflectance meter (CROMOCON LRV METER).

[0110] Examples Comparative example 1 2 1 2 3 4 5 6 7 8 Peel strength (kgf / in) 0.4 0.5 0.2 0.2 0.2 0.4 0.3 0.4 0.3 0.3 reflectivity(%) 60 55 70 60 60 35 55 50 70 50

[0111] Referring to Tables 1 and 2 above, it can be confirmed that the durability of the flooring material according to the embodiment is the best. That is, as the peel strength between the printing layer and the surface film layer is measured to be high, the flooring material is maintained without layer separation, thus having the advantage of excellent durability.

[0112] In contrast, in Comparative Examples 1 and 2, it can be seen that the peel strength of the flooring material decreases as the printing layer contains metallic pearl pigment. Furthermore, in Comparative Example 3, it can be seen that the peel strength of the printing layer and the surface film layer is significantly lower as the printing layer contains an excessive amount of metallic pearl pigment.

[0113] On the other hand, in the case of Comparative Example 4, the durability and peel strength of the flooring material are similar to those of the example, but the content of metallic pearl pigment included in the transparent pearl film layer is significantly low, so there is a problem in that it is difficult to achieve a natural metallic texture due to the addition of metallic pearl pigment.

[0114] In the case of Comparative Example 5, as the content of metallic pearl pigment in the transparent pearl film layer increased, the viscosity of the mixed composition for forming the transparent pearl film layer increased, making it difficult to mold into a film layer. Although a flooring material was manufactured by molding it into a film shape using heat and pressure, the adhesion between the lower substrate layer and the upper printed layer was poor, resulting in a significant decrease in the durability of the flooring material itself. This result is consistent with the low peel strength values ​​of the printed layer and the surface film layer, indicating that it is unsuitable for manufacturing flooring materials.

[0115] In the case of Comparative Example 6, the thickness of the transparent pearl film layer was thin, making it difficult to process into a film form, and the dispersibility of the metallic pearl pigment within the transparent pearl film layer was reduced, resulting in a negligible effect of improving the metallic texture.

[0116] In the case of Comparative Example 7, the thickness of the transparent pearl film layer was excessive, which increased the overall thickness of the flooring material and resulted in problems such as the flooring layer not remaining flat and curls being formed, thus degrading the quality of the flooring material.

[0117] In addition, in the case of Comparative Example 8, there was a problem in that the thickness of the opaque ink layer was thickened so that the metallic pearl pigment of the underlying transparent pearl film layer could not be observed, and consequently, the metallic texture effect appeared insignificantly.
