Description
Technical Field
The present invention relates to a sheet glass laminate printed steel sheet in which transparent and flexible sheet glass is laminated on an inkjet printed metal steel sheet on which various designs of high definition, images, textures, etc. are printed.
Background
In general, a surface-treated steel sheet printed with grain is used for building exterior materials, home appliance exterior materials, etc., and it is used by adjusting gloss through various clear coating. Such printed steel sheets are designed with various images and shapes on the surface thereof so as to enhance the aesthetic effect of a desired product or the decorative effect of a building.
With the gradual improvement of life quality, consumers not only consider the functions of products but also consider the appearance quality or design of the products as an important factor in selecting the products when buying home appliances or building materials, etc. In order to meet such demands of consumers, there has been a trend in recent years for printed steel sheets coated with a color steel sheet or provided with an exquisite appearance and texture by realizing various textures using ink. Such color steel sheets and printed steel sheets excellent in visual function of surface appearance are widely used for fire doors, interior elevator applications, high-grade buildings, interior decorations, home appliances, kitchens, furniture, and the like by satisfying individuality and high-grade. In particular, the printed steel sheet may be applied to various designs required by consumers and may exhibit high definition and high quality designs, and thus its demand is on the rise.
In the past, the printing steel sheet that has the line on the steel sheet finally coats the clear coat layer in order to prevent that the printing line from being damaged on the printing layer of design, through the clear coat layer as described above, more show printing line layer. However, in the conventional single-sheet type clear coat method, a part of high glossiness is achieved by screen printing, curtain coating, or the like, but the thickness of the film of the clear coat layer is about 50 to 100 μm, and is thick, and the surface becomes rough due to volatilization of the solvent caused by the heat curing method, so that it is difficult to achieve an elegant surface. In addition, for surface smoothness, a long curing time is used to achieve natural planarization, so productivity is also poor, and fire and the like are very liable to occur. In particular, there are limitations in exhibiting surface characteristics such as high glossiness, high hardness, and high distinctness of image of a glass surface required by customers, and high distinctness of image cannot be achieved due to surface roughness, and at present, fine surface quality such as high surface hardness, high glossiness, and the like cannot be achieved.

Best mode for carrying out the invention
Hereinafter, preferred embodiments of the present invention will be described. However, the embodiment of the present invention may be modified into various other embodiments, and the scope of the present invention is not limited to the embodiments described below. Further, embodiments of the present invention are provided to more fully illustrate the invention to those of ordinary skill in the art.
[ sheet glass laminate printing Steel sheet ]
The structure of a sheet glass laminate printed steel sheet according to one aspect of the present invention is schematically shown in fig. 1. When described with reference to fig. 1, a sheet glass laminate printed steel sheet according to an aspect of the present invention includes: a printed steel sheet 1 comprising a metal plate 11 and a printed layer 12 on the surface of the metal plate, the printed layer 12 having a design or pattern printed therein; an adhesive layer 2 formed by curing an ultraviolet curing type adhesive solution on the printed steel plate 1, the thickness of the adhesive layer 2 being 10-100 μm, and the adhesive layer 2 being transparent; and a flexible sheet glass 3 adhered by the adhesive layer 2.
Printed steel plate
The printed steel sheet 1 of the sheet glass laminated printed steel sheet according to one aspect of the present invention is not particularly limited, and may be preferably used in the present invention as long as it is a printed steel sheet currently in production or in the market. Further, the printed steel sheet 1 may include a metal sheet 11 and a printed layer 12 on a surface of the metal sheet, the printed layer 12 having a design or pattern printed therein. As a specific embodiment, the definition of the design or pattern may be high definition of 300dpi or more, but is not limited thereto.
As a non-limiting embodiment, the printed steel sheet 1 may be an ink-jet printed steel sheet. When a design or a pattern is printed by inkjet printing, high-definition full color (full color) printing of 300dpi or more is easily performed, and thus a minute shade difference, rich color, and a true color feel can be realized. Further, when the thin sheet glass 3 is laminated on the ink-jet printed steel sheet according to the present invention, a surface appearance similar to that of an actual natural material can be achieved, and thus there is an advantage in that an elegant decorative material can be obtained.
As a non-limiting modification, a Base (Base) color layer 4 and/or a primer layer 5 may be included between the metal plate 11 and the printed layer 12 of the printed steel plate 1. Fig. 2 (a) to (c) show the structure of the laminated printed sheet glass steel sheet according to the modification. The primary color layer 4 plays a role of representing primary colors of the printed steel sheet 1, and may have a thickness of 5-30 μm. In addition, the primary color layer 4 may be subjected to plasma treatment for adhesion to the print layer 12. In addition, the primer layer 5 functions to enhance adhesion between the metal plate 11 and the primary color layer 4 or between the metal plate 11 and the print layer 12, and the thickness of the primer layer 5 may be 1 to 10 μm.
Further, as another non-limiting modification, a pretreatment layer 6 may be further included between the metal plate 11 and the primer layer 5. Fig. 2 (d) shows a modified example of the pretreatment layer 6. The pretreatment layer 6 serves to improve the basic corrosion resistance of the metal plate 11 and to improve the adhesion of the metal plate 11 and the primer layer 5, and the thickness of the pretreatment layer 6 may be 0.1 to 2 μm.
Adhesive layer
The printed layer 12 of the printed steel sheet 1 may be provided with a transparent adhesive layer 2 for lamination with the sheet glass 3, and the adhesive layer 2 may be formed by applying an ultraviolet curable adhesive solution to the printed steel sheet 1 and then curing the solution.
First, the adhesive layer 2 is preferably formed of an ultraviolet curable adhesive solution. In the prior art, a film adhesive or a thermosetting adhesive is generally used when laminating glass on a building material. However, as shown in fig. 3, the printed steel sheet 1, particularly the ink-jet printed steel sheet, has a surface roughness of several micrometers (μm) to several tens of micrometers, and thus, when a film adhesive or a heat-curable adhesive is used on the printed steel sheet 1, fine surface distinctness and flatness cannot be obtained. When the film adhesive of fig. 4 (a) is described in more detail with reference to fig. 4, since the specific surface roughness due to ink droplets is transferred to the adhesive film and glass as it is, roughness may occur, and thus surface flatness defects may occur. In the case of the thermosetting adhesive of fig. 4 (b), a solvent (solvent) is contained in a general adhesive coating material, and as shown in the right photograph (refer to red circle) of fig. 4 (b), the solvent cannot be vaporized and escapes during the curing heat treatment, and remains in the adhesive coating film, so that there is a problem that bubbles may be generated. Therefore, in order not to transfer the surface roughness of the printed steel sheet to glass or to minimize the generation of bubbles, the adhesive in a solution form is more suitable than the solid phase film adhesive, and when the ultraviolet curing type adhesive solution is used, better surface quality characteristics can be obtained than the thermosetting type adhesive.
The adhesive layer 2 preferably has excellent transparent characteristics so that an image of the printed steel sheet is transmitted and displayed as it is. In detail, the adhesive layer 2 preferably has a high light transmittance of about 85% or more at a wavelength band of 550nm, and a Yellowness Index (yellow Index) is preferably 2 or less.
In addition, the adhesive layer 2 is preferably formed to have a thickness of 10 to 100 μm. When the thickness of the adhesive layer 2 is less than 10 μm, the roughness of the ink jet printed surface (printed layer) cannot be offset, and thus a problem may occur in terms of surface quality, i.e., freshness. On the other hand, when the thickness of the adhesive layer 2 exceeds 100 μm, problems in terms of color development or curing efficiency may occur due to the excessive thickness of the adhesive layer 2, and problems in terms of manufacturing cost increase may occur due to the use of a relatively large amount of adhesive solution.
Flexible sheet glass
A flexible sheet glass 3 having a thickness of 0.1 to 2mm may be laminated on the transparent adhesive layer 2. The material of the thin plate glass 3 is not particularly limited, but as a non-limiting specific embodiment, alkali-free borosilicate glass, soda lime glass, or tempered glass may be preferably used.
The sheet glass 3 should be freely bendable (flexible) and preferably thin to 0.1-2mm (sheet). Unlike the conventional thick plate glass, the freely bendable flexible thin plate glass 3 can be laminated on a printed steel plate, and has advantages of light weight and excellent light transmittance. In addition, due to the flexible nature of the flexible sheet glass, the characteristics of being able to be rounded after adhering the glass are also obtained. In addition, when the thickness of the thin plate glass 3 is less than 0.1mm, handling is difficult, and a problem of lowering of flatness may occur due to surface irregularities or external force when bonding the glass. On the other hand, when the thickness of the thin plate glass 3 exceeds 2mm, the pressure cannot be transmitted well due to the thick thickness, or the weight becomes heavy, and is not suitable in terms of economy.
In particular, the sheet glass 3 used in the present invention should be transmissive to ultraviolet rays and radiation rays in the visible wavelength region and the wavelength region below. In the present invention, a metal plate and a thin plate glass are laminated by interposing an adhesive layer 2, and the adhesive layer 2 is cured by an ultraviolet or radiation curing machine.
The sheet glass laminate printed steel sheet of the present invention having the above composition has a glossiness of 85% or more based on a 60-degree glossiness meter, and a freshness SW of 30 or less and an LW of 10 or less based on a freshness meter. The surface hardness based on pencil hardness may be 9H or more.
Further, the optical characteristics may be evaluated by measuring light in the region of 376.76 to 730nm with a Spectrophotometer (spectrocolorimeter), the L value (luminance, white luminance) may be 75 or more when white points (white point comparison) are evaluated, the HSL (H: hue, S: saturation, L: luminance) value may be more than 440000 based on the maximum saturation (saturation=1) value when the color gamut volume (HSL comparison) is evaluated, the reference value may be more than 1.6 when the color gamut concentration (maximum color concentration comparison) is evaluated, and the reference value may be more than 200000 when the absolute value of the color gamut volume (cube volume comparison) is evaluated. In particular, the present invention is characterized in that the reference value satisfies more than 1.6 when the color density is evaluated, and therefore a high definition image of the printed steel sheet can be displayed as an actual image level despite the formation of the sheet glass and the adhesive layer.
Specifically, the evaluation of the optical characteristics may be performed according to the following conditions. When the optical characteristics are evaluated under the following conditions, it can be determined that the scope of the present invention is satisfied when the above criteria are satisfied, but the present invention is not limited thereto.
The apparatus for evaluating optical characteristics used a 3x X-rite i1Pro 2 spectrophotometer, specifically, measurements were performed under D50M2 uv compensation mode (uv compensation mode) (2 degree standard observer (2degree Standard Observer by CIE 1931) through CIE 1931), spectral interval (3.3 nm), spectral band (107), spectral start (376.67 nm), spectral end (730 nm). In addition, the measurement software uses argylecms 2.0.1, specifically, the measurement was performed under the conditions of single channel step (single channel step) (8), gray axis step (32), sampling color scale (sampling color patches) (882). The software used for the analysis uses GamutVision, color ThinkPro, raw data Direct Analysis to evaluate the absolute values of white point, color gamut volume, color concentration, and Color gamut volume.
In the sheet glass laminated printed steel sheet according to one aspect of the present invention, the sheet glass 3 is laminated on the high definition printed steel sheet 1, and thus high hardness, high distinctness of image, stain resistance, and chemical resistance due to glass characteristics can be achieved, and by using a thin sheet glass, good interfacial adhesion and excellent color feel can be achieved.
Hereinafter, a method for manufacturing a laminated printed sheet of sheet glass according to another aspect of the present invention will be described in detail.
[ method for producing sheet glass laminate printed Steel sheet ]
The method of manufacturing a laminated printed steel sheet for sheet glass according to another aspect of the present invention comprises the steps of: preparing a printing steel plate 1; coating an ultraviolet curing type adhesive solution on the surface of the prepared printed steel plate 1 to form an adhesive layer 12; adhering a sheet glass 3 on the printed steel sheet coated with the ultraviolet curing type adhesive solution; applying pressure to the adhered sheet glass to remove bubbles formed between the ultraviolet curing type adhesive solution and the sheet glass 3; and curing the ultraviolet-curable adhesive solution by irradiating ultraviolet rays.
Preparation of printed Steel sheet and step of Forming adhesive layer
First, a printed steel sheet 1 including a metal plate 11 and a printed layer printed with various designs of high definition is prepared, and a transparent ultraviolet-curable adhesive solution is coated on the printed steel sheet 1. The method of applying the ultraviolet curable adhesive solution may be performed by using an application device such as a roll coater or a slot knife alone, or an operator may manually apply with equipment such as a brush or a spray gun. However, the present invention is not limited thereto, and any conventionally known method may be used as long as the entire adhesive solution can be uniformly applied to the printed steel sheet.
The ultraviolet curable adhesive solution may be preferably used in the present invention as long as it is an adhesive that can be cured by ultraviolet rays and has adhesive force. In addition, an adhesive solution cured by radiation may also be used. As one non-limiting embodiment, the uv curable adhesive solution may include a polyester acrylate oligomer having 6 or more functional groups, a urethane acrylate oligomer having 2 functional groups, one or more photo-curable monomers, a photoinitiator, and other additives. As examples of the photocurable monomer, TMPTA, THFA, PETA, IBOA may be mentioned, and as examples of the photoinitiator, 2-Hydroxy-2-methyl-1-phenyl-propane (2-Hydroxy-2-methyl-1-phenyl-propane), oxy-phenyl-acetic acid2- [2oxo-2phenyl-acetoxy-ethoxy ] -ethyl ester (oxy-phenyl-acetic acid2- [2oxo-2 phenyl-acetic acid-method ] -ethyl ester) may be mentioned. Further, as the other additives, there may be included phosphoric acid acrylate (Phosphoric acid acrylate) (acid value of 250), polyether siloxane compound (polyether siloxane compound), fluoroalkyl compound (Fluoroalkyl compound).
The ultraviolet curable adhesive solution should be uniformly coated on the entire surface of the printed steel sheet 1. For this reason, it is preferable to coat the entire surface of the printed steel sheet with a predetermined thickness, and more preferably, to coat a predetermined amount of the adhesive solution with a predetermined interval. When coated at predetermined intervals, the adhesive solution is uniformly spread and dispersed over the entire surface of the printed steel sheet by pressure through the subsequent steps of adhering and pressing the sheet glass 3, so that waste of the adhesive solution can be minimized.
In addition, when the ultraviolet curable adhesive solution is applied, it is preferable to construct a roller or a base that can support the printed steel sheet 1. In the case of a steel sheet in a coiled state, it is preferable to provide a roller made of rubber or metal, and in the case of a sheet, it is preferable to provide a base made of plastic, metal or wood, so that the entire surface of the sheet is supported. When the ultraviolet curable adhesive solution is applied to the roller or the base as described above, the application can be performed more easily and uniformly.
Adhering sheet glass and pressure applying step
After the ultraviolet curing type adhesive solution is coated on the printed steel plate 1, a flexible thin plate glass 3 having a thickness of 0.1-2mm is adhered thereon. And, after the sheet glass 3 is adhered, a pressure of 2 to 10kgf is applied to the sheet glass 3 to press. By applying an appropriate pressure to the sheet glass 3, the thickness of the adhesive layer 2 can be appropriately adjusted, and bubbles formed in the ultraviolet curable adhesive solution and the sheet glass 3 can be easily removed.
When the pressure applied to the sheet glass 3 is less than 2kgf, bubbles remaining at the bonding interface are trapped due to the pressure decrease, or the pressure cannot be transmitted to the entire sheet glass, so that a defect of an unbonded portion between the sheet glass and the bonding layer may occur. On the other hand, when the pressure applied to the sheet glass 3 exceeds 10kgf, the thickness of the adhesive layer 2 is reduced due to the high pressure, so that the rough surface of the printed layer is adhered as it is, whereby defects in the fresh-image property may occur, and the adhesive solution overflows outward, and thus the apparatus may be contaminated. Therefore, the pressure is preferably controlled to 2 to 10kgf.
The method of applying pressure is not limited as long as it is a conventional method of extruding glass which is generally used. As a non-limiting embodiment, the pressing may be performed by a roll pressing method in which a pressing force is applied by laminating rolls (pressing rolls) located above and below the printed steel sheet 1. Further, as a non-limiting embodiment, the adhering means and the pressing means used in the step of adhering the sheet glass and applying pressure may include: a roll press including laminating rolls located above and below the printed steel sheet 1, and a sheet glass take-out apparatus provided at an upper side of the roll press; and a supporting member provided between the thin plate glass 3 and the printed steel plate 1 formed with the adhesive layer 2 so as to maintain the thin plate glass 3 in a flat state.
The laminating roller is preferably formed of a rubber roller, and when the printing sheet and the sheet glass layer are pressed against each other, the pressing roller is preferably moved by a conveyor so as to be movable in the longitudinal direction of the base material (sheet steel). In addition, the laminating roller may include a lifting driver and a pressure adjusting device so that the thickness of the adhesive layer applied to the printed steel plate may be adjusted by controlling the lifting height and the pressure. Further, the above-described members are provided at the widthwise edges of the sheet glass, so that the sheet glass can be kept flat. The above-mentioned members may be formed of a conveyor belt, rollers, or the like, but are not limited thereto, and any method may be used as long as the transparent sheet glass can be kept flat.
Step of curing the adhesive layer
Thereafter, the pressed sheet glass laminate printed steel sheet may be passed through an ultraviolet curing machine to cure the ultraviolet curing type adhesive solution, thereby forming a coating film having a thickness of 10 to 100 μm. At this time, the irradiated ultraviolet rays may be in a wavelength band region of 300 to 400 nm. However, the present invention is not limited thereto, and any conventionally known method may be used as long as it is a method capable of curing the ultraviolet curable adhesive solution.
Further, in the ultraviolet curing, microbubbles at the edge portion may be removed by a depressurizing method such as a depressurizing device.
[ sheet glass bonding System of printed Steel sheet ]
The sheet glass bonding system of the printed steel sheet of another aspect of the present invention includes: a coating device for coating an ultraviolet-curable adhesive solution on a printed steel sheet; a glass adhering device which is provided at a rear end of the coating device and adheres the thin plate glass on the adhesive solution; a pressing means connected to the glass adhering means and adhering the adhesive solution and the glass film by pressing the glass film; and a curing device which is provided at a rear end of the pressing device and cures the ultraviolet-curable adhesive solution by irradiating ultraviolet rays to form a coating film. Further, a pressure reducing device for removing microbubbles at the edge portion by reducing pressure may be included as needed.
Detailed Description
Hereinafter, the present invention will be described more specifically with reference to examples. It should be noted, however, that the following examples are provided for illustration only and are not intended to limit the scope of the claims. This is because the scope of the invention is determined by what is recited in the claims and what is reasonably derived therefrom.
Example (example)
First, as an example of the invention, a urethane acrylate-based ultraviolet curable coating solution mounted on a coating pan was applied onto a coating roll, and then a transparent adhesive solution was applied onto an inkjet-printed steel sheet on which high-definition lines (definition: 1200 dpi) having a thickness of 1mm were printed at a thickness of 30 to 40 μm, and then a sheet glass having a thickness of 400 μm and a light transmittance of 90% or more was adhered thereon. Thereafter, the film was pressed with a pressing roller at a pressure of 3kg/f to adhere the coating solution and the film, and then passed through an ultraviolet curing machine to cure the adhesive solution to bond, thereby manufacturing a glass laminate steel sheet.
Further, as comparative example 1, a high-gloss transparent coating liquid was coated on an inkjet-printed steel sheet printed with high-definition lines having a thickness of 1mm, and a coating film was formed by a heat curing method. Further, as comparative example 2, a transparent adhesive solution was coated on the same ink-jet printed steel sheet at a thickness of 30 to 40 μm, and then tempered glass having a light transmittance of 90% or more and a thickness of 5mm was adhered, and then it was passed through an ultraviolet curing machine to be cured.

[ evaluation of stain resistance, chemical resistance and processability ]
The stain resistance was evaluated by whether or not a trace remained when the line was drawn on the surface of the manufactured product by a whiteboard pen and then erased. The case where no trace is left at all and the case where the film is cleanly erased is referred to as "excellent", the case where a blurred trace is left is referred to as "delta", and the case where the film cannot be erased is referred to as "x".
For chemical resistance, 95% acetone solution was dropped on the surface of the manufactured product with a drop diameter of 2cm, then covered with a cap and left for 2 hours, and then the acetone solution on the surface was wiped off with a cloth, the surface was clean and was represented as "excellent" when there was no damage, the coating film was represented as "delta" when a part of the coating film was damaged, and the coating film was all swelled or peeled off and evaluated as "x".
In addition, the invention examples and the comparative examples were subjected to circular processing to evaluate the workability, and when 5 products were processed on the basis of 800R, 5 out of 5 were each free from surface defects or damage and were good, were indicated as excellent, 4 out of 5 were good were indicated as o, 2 to 3 out of 5 were good were indicated as Δ, and 1 or less out of 5 were indicated as good.
[ evaluation of optical Properties ]
In order to compare the color development characteristics of the inventive examples and comparative examples, after 882 sample colors were printed, light in the 376.76-730nm region was measured by a spectrophotometer, and the absolute values of white point, color gamut volume, color density, and color gamut volume were evaluated according to the following evaluation methods, and the results are shown in table 1 below.
Evaluation of white points (comparison of white points)
The white point is an index indicating the brightness of white, and is indicated as good when the L value exceeds 75, and is indicated as good when the L value is 50 to less than 75.
Evaluation of color gamut volume (comparison of HSL)
The color gamut volume is an index representing a color space region reproducible by each medium in a contour line which is a region of the entire solar light, and is expressed as whena saturation reference value actually reproduced exceeds 440000, as ∈when the saturation value is 350000 to less than 440000, and as ∈when the saturation value is less than 350000, as HSL (H: hue, S: saturation, L: brightness) is evaluated based on the maximum saturation (saturation=1) value.
Evaluation of color concentration (comparison of maximum color concentration)
The color density represents a ratio of saturated states such as blackness (black) or chroma (chroma), and is represented as goodwhen a reference value exceeds 1.6, as o when the reference value is 1.3 to less than 1.6, and as delta when the reference value is less than 1.3.

TABLE 1
As shown in table 1 above, it was confirmed that the inventive examples of the sheet glass having a flat surface adhered thereto according to the present invention were excellent in glossiness and distinctness of image, hardness and workability, and also excellent in optical characteristics. However, in the case of comparative example 1, optical characteristics and processability were good, but there was a limitation in achieving glossiness or freshness due to volatilization of the solvent of the thermosetting system. Further, the laminated glass was lower in hardness and inferior in stain resistance and chemical resistance as compared with the invention example or comparative example 2. In the case of comparative example 2, the glass was laminated, and the glossiness, the distinctness of image, the hardness, the stain resistance, and the chemical resistance were at the level of the present invention and were excellent, but the thickness of the laminated glass was too thick, and therefore it was confirmed that the optical characteristics concerning the color development ability, such as white point, color gamut volume, color density, and absolute value of color gamut volume, were inferior to those of the present invention, and the workability was also inferior.
While the present invention has been described with reference to the embodiments, those skilled in the art will appreciate that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the appended claims.
