Description

Method for presenting pictures using thin mother-of-pearl sheet and mother-of- pearl sheet picture manufactured by the method}

The present invention relates to a method capable of constructing various screens by using a translucent translucent mother board sheet obtained by processing mother-of-pearl in a thin plate shape, and also relates to a thin mother-of-pearl sheet screen constructed by the method.

Mother-of-pearl is a natural material that has been widely used as a high-quality surface decoration of furniture and various kinds of jewelry because of its beautiful and colorful pattern, color, and luster. If you want to decorate the surface of furniture using mother-of-pearl in the prior art, attach the pattern with the pattern you want to express to a natural mother-of-pearl, and then cut the mother-of-pearl along the pattern to make the necessary pattern pieces. The method of attaching the pattern to the part to express the pattern is traditionally used.

Such a conventional self-opening method requires a highly skilled technical manpower, relies on a large number of manual labor and costs expensive materials. In connection with this problem, a method of manufacturing a decorative pattern mother-of-pearl is known which processes mother-of-pearl in a thin flat sheet shape and silk-prints the mother-of-pearl sheet surface.

As a conventional method for processing mother-of-pearl in a thin flat sheet form, the following method is known. That is, as a method of manufacturing a mother-of-pearl, the original plaque is cut into a rectangle of a predetermined size, for example, 1cm-1.5cm in width and 5cm-15cm in length by using a diamond wheel, and the mother-of-pearl is thinly rolled to a thickness of about one sheet. The ends of the adhesive tape are attached to each other over the entire length of the adhesive tape, and then the mother-of-pearl plate having a width of about 20 cm-30 cm and a length of 15 cm-25 cm is formed, and epoxy and polyamide resins are applied to the mother-of-pearl plate surface. A mixture of 2: 1 or 4: 1 is applied, and the mother-of-pearl flat plate coated with the mixture is laminated on each layer within the range of about 500 sheets of the maximum number of sheets by using a release paper, and then a hot wire is formed on the upper and lower plates. Press the press to 1.5 ~ 2 hours at 70-80 ℃ temperature for 2-3 hours, and then remove the release paper for each layer. There is a method of obtaining a smooth thin mother-of-pearl mother-of-pearl sheet by repeated cutting process, another method, in the domestic patent publication No. 92-8871 filed by Kim Jong-su, a Korean national A process of collecting the wastes, an attaching process of attaching the collected waste mothers to the paper so as to have a predetermined area, and a condensation process of applying a transparent epoxy on the waste magnetic bodies attached to a certain area on the paper and hardening them. A first heat treatment step of stacking about 20-30 pieces of waste objects after the process and compressing them for about 5 minutes with a pressurization press of about 150 tons, and then artificially drying them in a sealed warmer at about 120 ° C. for about 90 minutes; The same conditions as the first natural cooling process for naturally cooling for about 3 hours after the first heat treatment process and the first heat treatment process performed after the first natural cooling process A second heat treatment step, a second natural cooling step of naturally cooling for about three hours after the second heat treatment step, a resin that has solidified and fixed on the upper and lower surfaces of each of the waste objects having completed the second natural cooling step, etc. A method for producing a smooth disc mother sheet of a size sufficient to form a pattern by cutting and polishing an adhesive of a diamond wheel is disclosed. Such smooth disc mother-of-pearl sheet is cut into a predetermined pattern as needed, and is commonly used to attach to various furniture surfaces.

On the other hand, Korean Patent Publication No. 97-3939, which was filed in Korea by Mr. Oh Jae-duk, is a method of using the original mother-of-pearl sheet manufactured by a conventionally known method as described above. Disclosed is a method of manufacturing a decorative pattern mother-of-pearl plate having a pattern of the same shape simply by screen printing of various colors so that the mother-of-pearl pattern is expressed in an intaglio form. Referring to the method of manufacturing a decorative pattern mother-of-pearl disclosed in the patent of Oh Jae-deok in detail, as shown in Figure 10, the surface of the thin mother-of-pearl sheet 11 of a predetermined width that is smoothly polished, the surface is not polished Forming a transparent resin coating layer 12 by coating a transparent epoxy resin on an uncured surface and curing the transparent epoxy resin; and screen printing the surface of the smoothly polished mother-of-pearl sheet to form various forms formed by the printing layer 13. Causing the mother-of-pearl pattern to be expressed by the mother-of-pearl of the non-printed layer, coating the transparent epoxy resin on the upper surface of the printing layer 13 to form a transparent resin film layer 14, and curing the printed material. Disclosed is a method of manufacturing a decorative pattern mother board comprising the step of polishing the coating layer 14 on the upper surface of the layer to give gloss.

However, the method of manufacturing a decorative pattern mother-of-pearl plate according to the patent of Oh Jae-duk is a technology that uses a very thin brittle mother-of-pearl sheet surface having a thickness of only 0.2 mm-0.5 mm as a direct printing surface. When coating and polishing the epoxy resin, the mother-of-pearl sheet is not only very fragile, but also silk screen printing several times as many as the number of chromaticities directly on the surface of the material sheet, which requires careful attention and multi-step process. There is a problem falling.

The present invention is basically a thin thin mother-of-pearl like the technique described in Korean Patent Publication No. 97-3939 by Mr. Jae-deok Oh in order to solve the problem of the traditional mother-of-pearl opening method to form a pattern by finely cutting the mother of pearl pieces Using the sheet is the same but crucially different from Patent Publication No. 97-3939, the mother-of-pearl sheet manufactured by the known method as described above is only 0.2 mm-0.5 mm in thickness so that it is sufficiently lighted. Taking care of the fact that it is a translucent material that is transparent enough, it is possible to effectively obtain the mother-of-pearl pattern to be expressed without printing directly on the mother-of-pearl sheet surface. The screen display method using the thin mother-of-pearl sheet according to the present invention and the mother-of-pearl sheet screen using the same method are independent of the mother-of-pearl sheet, a transparent medium such as glass, and / or an opaque material such as paper. It prints a predetermined pattern on the surface of and then merges it on the front and back of the mother-of-pearl sheet to obtain the mother-of-pearl pattern by using the transparency of the mother-of-pearl sheet. There is this.

It is an object of the present invention to provide a screen display method using a thin mother-of-pearl sheet and a thin mother-of-pearl sheet screen using the same method, which may have a low defective rate, a low manufacturing process, and a simple process to increase productivity.

Hereinafter, with reference to the embodiments shown in the accompanying drawings, a preferred embodiment of the screen display method using a thin mother of pearl sheet according to the present invention and a thin mother of pearl sheet using the same method will be described in detail.

Step 1 (Manufacturing of thin mother-of-pearl sheet)

The thin mother-of-pearl sheet manufacturing process as a 1st process is not different from the conventionally well-known method of processing mother-of-pearl in the shape of a thin flat sheet. For example, as described above, the mother-of-pearl strip is cut into a rectangle of a predetermined size, such as 1 cm-1.5 cm and 5 cm-15 cm, using a diamond wheel, and the mother-of-pearl is thinly sliced into a piece of paper with a mother-of-pearl. The ends are attached to each other so as to overlap each other and processed to have a predetermined area, for example, an area of 20 cm to 30 cm and 15 cm to 25 cm in width to form an approximately rectangular paper-shaped mother plate as a whole, and an epoxy resin on one surface of the mother plate. And a mixture of about 2: 1 or 4: 1 blended with polyamide resin was applied in a thin layer, and the mother-of-pearl plate coated with this mixture was laminated on each layer within a range of about 500 sheets with a release paper. The resultant was pressurized with a 1.5 ton pressure press formed with a hot wire on the upper and lower plates and pressed for about 2-3 hours at a temperature range of 70-80 ° C., followed by removing the release paper for each layer. To the front side and the back side of the mother-body plate processing diamond cutting wheel (repeated several times, if necessary) to obtain a smooth surface and a paper-thin mother-of-pearl sheet 20 of about 0.2mm-0.5mm thickness magneto smooth. This thin mother-of-pearl sheet is a milky, light-translucent semi-transparent mother-of-pearl, which is processed using natural mother-of-pearl, and emits a brilliant purple color on its surface.

2nd process (1st printing process)

The screen display method using the thin mother-of-pearl sheet and the thin mother-of-pearl sheet screen using the method according to the present invention, as described above, to effectively obtain the natural mother-of-pearl pattern to be expressed without printing directly on the mother-of-pearl sheet surface As a feature, the first printing process does not print on the surface of the mother-of-pearl sheet 20, but prints the shape or color 32 to be expressed on the separate first screen 30, as shown in FIG. It is a process. For example, if you want to express the folk painting of Kim Hong-do with mother-of-pearl, you can print the folk painting on the plain flat paper (first screen) by the usual printing method or draw it with a brush and draw a sketch (32). It is a process to do it. The first screen 30 on which the sketch is drawn may be used in addition to paper, such as slabs, copper plates, wooden boards, linoleum plates, synthetic resin boards, glass plates, and the like. The screens printed or directly drawn on the first screen may be achromatic black and white. Various natural colors may be used. Since the first screen 30 in which a predetermined picture or character is colored or printed is positioned against the rear surface 22 of the mother-of-pearl sheet 20 as shown in FIGS. 2 and 5A to 6, the first screen 30 is the first screen 30. The size of the screen 30 is smaller than or equal to the size of the mother-of-pearl sheet.

3rd process (2nd printing process)

In the second printing process, as shown in FIG. 2, a predetermined intaglio pattern 42 is printed on the second screen 40 of the transparent material which faces the front surface 24 of the mother-of-pearl sheet 20. It is a process. The first screen 30 described above is placed against the back surface 22 of the mother-of-pearl sheet 20, so that the entire sketch 32, which is colored or printed on the first screen, is a cross-section of the translucent mother-of-pearl sheet 20. Is transmitted to the front surface, and the predetermined engraved pattern 42 printed on the transparent material flat surface (second screen) which is opposed to the mother-of-pearl sheet on the front of the mother-of-pearl sheet is the mother-of-pearl. The sketch printed on the first screen appearing through the front surface of the sheet is clearly shown in the intaglio outline.

For example, when the sketch 32 shown in the first screen 30 is a circle 32 having a predetermined diameter colored in red, green and yellow, as shown in FIG. The mother-of-pearl pattern appearing through the mother-of-pearl sheet front when placed against the mother-of-pearl sheet back surface 22 is the same as the three-color circle, but on the front of the mother-of-pearl sheet, an opaque black star as shown in FIG. Intaglio pattern (star shape is transparent part 42 without pigment applied, and black opaque pigment part 43, and star shape appears as transparent intaglio) When the glass plate (second screen) 40 is placed, the pattern recognized by the human eye through the front of the glass plate (the pattern has a mother-of-pearl texture because it passes through the mother-of-pearl sheet) is shown in FIG. Tricolor star mold as shown in When the transparent glass plate (second screen) 40 in which the mother-of-pearl pattern of the image is printed and the flower-like engraving pattern 42 is printed in opaque black as shown in FIG. The pattern recognized by the human eye through the front surface is a mother-of-pearl pattern of tricolor flowers, as shown in Figure 5 (b).

Meanwhile, in the above example, when a three-color star or a three-color flower shape is directly shown on the first screen 30, it may be considered that stars or flower prints are unnecessary on the second screen as described above. Since the illustrated sketch 32 is recognized by light transmission through the milky translucent mother-of-pearl sheet, the picture shown on the first screen 30 loses its light a little while transmitting the mother-of-pearl sheet 20 in particular. Since the clarity of the pixels constituting the outline of the sketch is reduced, in consideration of this point, if an external outline of the mother-of-pearl pattern or a shape boundary line based on color classification is desired, an opaque outline on the second screen 40 is used. There is an important technical meaning in printing (輪 廓 線 圖) and placing it on the front of the mother-of-pearl sheet 20. Also, the second screen such as a glass plate is placed on the mother-of-pearl sheet in front of it. It also protects the mother-of-pearl sheet by preventing external contact with the surface. Therefore, in the present invention, the second screen itself may be regarded as an essential element, but the contour print of the opaque negative pattern printed on the second screen 40 may be selected in relation to the picture shown on the first screen. It can be seen as an enemy element.

4th process (support process)

The mother-of-pearl sheet 20 used in the present invention is a thin plate having a very thin thickness, and since the first screen 30 located on the back of the mother-of-pearl sheet is also a very thin and flexible paper material, for example, as shown in FIG. On the back surface of the first screen 30, a rigid support flat plate 50 for pressing and supporting the first screen 30 and the thin mother-of-pearl sheeting flat must be positioned. However, when the first screen 30 is a hard slab, a copper plate, a wooden board, a linoleum plate, a glass plate, a synthetic resin plate, etc. instead of a paper material, a separate support plate is not necessary. It can be seen as an additional process that is chosen depending on whether When the screen using a thin mother-of-pearl sheet according to the present invention is used as a screen for decorating one surface of the furniture, for example, the furniture surface itself (not shown) may function as the support plate and to be displayed on the picture frame. In the back frame (not shown) of the picture frame may function as the support plate 50. In the case of a picture frame, the glass (not shown) in front of the picture frame may also function as the second screen 40.

On the other hand, when the screen using the thin mother-of-pearl sheet according to the present invention, for example, as a decorative surface of the furniture, if the second screen 40 exposed on the surface of the furniture is a glass screen, the glass material is a basic material of the furniture It is not suitable for wood and other materials. Therefore, when the present invention is to be applied to the wooden furniture surface, as shown in Fig. 9, the transparent adhesive film sheet 40a can be used as the material of the second screen, and the transparent adhesive film is post-furnished on the surface of the furniture. By applying the same coating 411 as the protective coating (not shown, for example transparent epoxy resin coating) for the thin mother of pearl sheet sheet according to the present invention can be expressed to have the same height and the same texture as the furniture surface (not shown). . Reference numeral 412 denotes a transparent adhesive material. The transparent adhesive film 40a may be, for example, a so-called veneer sheet having the same pattern as natural wood. In the case of the veneer sheet, only a part of the transparent adhesive film 40a may be printed so as to print the above-mentioned opacity outline on the transparent portion.

Next, an industrially applicable example of a screen using a mother-of-pearl sheet according to the present invention will be described with reference to FIGS. 7 and 8. Figure 7 is an exploded perspective view showing an example of the configuration of the signboard is marked department name and the like hanging on the corridor wall, such as government offices, according to the present invention, Figure 8 is a front view of the coupling state. Reference numeral 30 denotes a first screen of white aluminum material in which a predetermined decorative pattern 33 is printed on a smoothly surface-treated surface, and reference numeral 20 denotes printing anything located in front of the first screen 30. Transparent translucent thin mother-of-pearl sheet, wherein 40 is a transparent glass on which an opaque black rectangular border outline 41 and a patterned outline 43 corresponding to the sketch 33 on the first screen are printed along the edge; The transparent acrylic second screen is displayed. When the department name sign board configured as described above is viewed from the front, a message with a high-profile mother-in-law pattern is obtained with the necessary message as shown in FIG. Here, reference numeral 60 denotes a bolt as an example of a fixing means for fixing the first screen 30, the thin sheet mother sheet 20 and the second screen 40 to be in close contact with each other.

Screen display method using the thin mother-of-pearl sheet according to the present invention and mother-of-pearl sheet screen using the same method is relatively easy to handle paper, slab, metal plate, without printing anything on the surface of the thin mother of pearl sheet Since the colored or printed pixels are made to be colored or printed only on a glass plate, an acrylic plate, or the like so that the thin mother-of-pearl sheet light transmits to the visible, there is no problem such as damage to the mother-of-pearl sheet.

In addition, the screen display method using the thin mother-of-pearl sheet and the mother-of-pearl sheet screen using the method according to the present invention is made by a separate process on the first and second screens, regardless of the printing sheet Repeated reproduction of the same pattern is made very easy and easy by the divisional process, and the printing method is not only silk screen printing but also computer output printing, photography, direct painting, textile printing, light emitting material printing, etc. Depending on the choice, there is an advantage that you can get different feelings. In addition, the present invention can be assembled in the field as well as factory production, each material provided separately, and can be replaced by inserting the printing on the first and second screens as needed, which can expand the selection and viewing width of the pattern There is an advantage.
