[Prior art] With the advancement of information processing using radio waves and the advancement of communication technology, in the existing office building or general residential building, from the viewpoint of preventing malfunction of electronic equipment or preventing information leakage, external electromagnetic ground occurs. The need to cover the inside of the building. In the case of electromagnetically shielding the inside of a building, an electromagnetic wave isolation wallpaper with electromagnetic wave isolation is attached to a wall surface inside the building. The room providing electromagnetic wave isolation is called an electromagnetic wave isolation room. The electromagnetic wave isolation wallpaper is described in Patent Documents 1 to 3, for example. The electromagnetic wave isolation wallpaper of Patent Document 1 is on the entire back surface of the wallpaper material made of decorative paper, woven or non-woven fabric, so that (overlapping glue) protrudes from one side of the width direction of the wallpaper material and attaches the wallpaper material only (Overlapping adhesive) Electromagnetically isolated interior fabric (wallpaper) of conductive film with wide width and width. The conductive film is copper foil or aluminum foil, and the thickness of the conductive film is 20 // m or less. The electromagnetic wave isolation wallpaper of Patent Document 2 is provided with a vinyl chloride protective layer for preventing scratches on the front surface and the back surface, and a conductor made of an aluminum metal foil is used as an insulation layer 164 -5-(2) (2) 200409588 layer. The electromagnetic wave-isolated wallpaper of Patent Document 3 is formed by spraying zinc, zinc / aluminum alloy on a substrate such as a wallpaper by a metal spraying method to provide electromagnetic wave isolation. Furthermore, the electromagnetic wave isolation chamber having the electromagnetic wave isolation property is produced by constructing a gypsum board with aluminum foil attached thereto. In this case, an electromagnetic wave isolation chamber is manufactured as follows. That is, an aluminum foil is pasted on a gypsum board, the gypsum board is mounted on a wall, etc., and then a conductive tape is attached to the aluminum foil to electrically connect the adjacent aluminum foils of the gypsum board to each other 'to connect the gap between the gypsum board and the gypsum board. Then, a wallpaper for decoration is attached to the gypsum board to form an electromagnetic wave isolation room. In addition, after construction of the gypsum board, aluminum foil is pasted on the gypsum board. Secondly, conductive tape is connected to the butt joints of the adjacent aluminum foils of the gypsum board. Then, a decorative wallpaper can be placed on the gypsum board to create an electromagnetic wave isolation room. [Patent Document 1] Japanese Patent Application Publication No. 2001-60789 [Patent Literature 2] Japanese Patent Application Publication No. 2000-54523 [Patent Literature 3] Japanese Patent Application Publication No. 6-326492 Since the electromagnetic wave isolation wallpaper has a conductive metal foil with high conductivity, the electromagnetic wave isolation is good. Conversely, it is not good that it is wound into a roll shape in the form of a normal product transport. That is, since the conductive metal foil has low flexibility, even if the roll of the roll is unwound (3) (3) 200409588, there are still shortcomings in winding, making it difficult to apply. In addition, since the creases or creases remain if they are strongly bent or the like, the new design properties after construction are reduced. Therefore, the electromagnetic isolation wallpaper with conductive metal foil is not easy to handle, and requires special skills during construction. Therefore, construction is usually performed for specialized workers. Furthermore, in the case of manufacturing an electromagnetic wave isolation chamber, when an aluminum plaster-attached plaster board is used, there is a problem that it is difficult to attach the aluminum foil to a gypsum board. That is, since conductive metal foils such as aluminum foils have shape-maintaining properties, and are prone to wrinkles, they can be attached only by specialized workers. In this way, when manufacturing an electromagnetic wave isolation room, it is necessary to hire a specialized worker. For the cost of this purpose, the work must be carried out in accordance with the worker's schedule, and the work period often becomes longer. [Summary of the Invention] The purpose of the present invention is to provide excellent softness, and the occurrence of ® caused by the winding defect of the roll is suppressed, and no occurrence of folds or creases. And electromagnetic wave isolation wallpaper with excellent electromagnetic wave isolation. Furthermore, its purpose is to provide a method for manufacturing such an electromagnetic wave isolation wallpaper and an electromagnetic wave isolation room using the electromagnetic wave isolation wallpaper. The electromagnetic wave isolation wallpaper of the present invention includes a wallpaper substrate, and a metal-containing resin composition composed of a metal-containing resin component. Resin coating. In the electromagnetic wave isolation wallpaper of the present invention, a metal-containing resin coating layer may be formed on one of the -7- (4) (4) 200409588 surfaces of the wallpaper substrate, and an adhesive layer may be formed on the other surface. Further, a coating layer for wallpaper decoration is formed on the metal-containing resin coating layer. The electromagnetic wave isolation room of the present invention is characterized in that the above-mentioned electromagnetic wave isolation wallpaper is attached. The electromagnetic wave isolation chamber of the present invention has better electromagnetic wave isolation performance of 1 OdB or more in the entire region of the electromagnetic wave electric field component in the range of 10 MHz to 1 GHz. Furthermore, the electromagnetic wave isolation chamber of the present invention may be a metal-containing resin coating layer at the abutting portion of these electromagnetic wave isolation wallpapers, and the conductive film may be connected to each other. The method for manufacturing an electromagnetic wave-isolated wallpaper of the present invention is characterized by having a metal-containing resin coating layer forming process for forming a metal-containing resin coating layer on a wallpaper substrate. The manufacturing method of the electromagnetic wave isolation wallpaper of the present invention has a heat treatment process. The heating process of the metal-containing resin coating layer is preferably performed at least once. At this time, the temperature of the heat treatment is preferably 50 to 200 ° C. In addition, it is preferable to treat the metal-containing resin coating layer under pressure during the heating process. In this case, after heat treatment at a heating temperature of 50 to 150 ° C, it is preferable to perform pressure treatment while heating at a heating temperature of 50 to 200 ° C. [Embodiment] The electromagnetic wave isolation wallpaper of the present invention has a wallpaper base material; and a metal-containing resin coating layer composed of a resin component containing a metal bag (8) (5) (5) 200409588. Among them, non-combustible paper, non-combustible paper, or ordinary paper with a floor mass (per m3) of 50 g to 200 g, which is generally used for wallpaper, can be used as the wallpaper base material. The wallpaper substrate may be provided with a resin film or a drug for purposes such as waterproof processing, if necessary. The metal contained in the metal-containing resin coating layer is made of a metal such as gold, silver, copper, aluminum, nickel, zinc, platinum, titanium, cobalt, beryllium, palladium, or the like, and has an electrical conductivity such as an alloy containing these metals. In addition, conductive carbon is also contained in a metal in this invention. Among these, at least one selected from the group consisting of gold, silver, copper, aluminum, and nickel is particularly preferred. Furthermore, since antibacterial or antifungal properties are found in wallpapers, metals with high antibacterial properties such as silver are better. The average particle diameter of these metals is better because of electromagnetic wave isolation, so 0.1 ~ 2 0.0 # m is preferred. The shape can be any of spherical, needle-like, and scale-like shapes. However, from the viewpoint of reducing surface resistance, scale-like shapes are preferred, and the average particle diameter of the scale-like metal is slightly smaller than the average particle diameter. Metal particles. The resin component of the metal-containing resin coating layer is not particularly limited. For example, polyurethane-based, polyester-based, polyamide-based, polysiloxane-based, polyfluoro-based, polyethylene-based, styrene-butadiene-based, and nitrile can be used. Synthetic resins such as butadiene and epoxy. These synthetic resins can be obtained in the form of a solution dissolved in a solvent, a latex emulsified and dispersed in water, a chip-like solid body, and the like. The metal content in the metal-containing resin coating layer is preferably from 10 to 95% by mass, and more preferably from 50 to 90% by mass. The preferred region for the metal content varies depending on the metal species. However, if it is more than necessary, flexibility is impeded, and if it is too small, the electromagnetic wave isolation cannot be fully exerted. Although the thickness of the metal-containing resin coating layer is not particularly limited, but because it is easy to use as a wallpaper, it is usually about 5 to 2000 // m, preferably 5 to 8 0 // m 〇 The surface resistance is fully exerted due to the electromagnetic wave isolation function. Therefore, it is preferably less than 5 Ω / sq, and more preferably less than 1 Ω / sq. This surface resistance is found by appropriately combining the type of the metal, the amount of the metal added, the thickness of the metal-containing resin coating layer, and a manufacturing method described later. Among them, the surface resistance is a radon measured in accordance with JIS K-7 194 using a surface resistance measuring device. Furthermore, it is preferable to laminate the wallpaper substrate and the metal-containing resin coating layer using an adhesive. If an adhesive is used to laminate the wallpaper base material and the metal-containing resin coating layer, the metal-containing resin coating layer can be made thin and uniform, and at the same time, electromagnetic wave isolation and flexibility can be further improved. Furthermore, if it is adhered with an adhesive, the durability against kneading can also be improved. Although known adhesives can be used, urethane resins or polyester resins are preferred. Furthermore, it is preferable to use a crosslinking agent from the viewpoint of durability. Although the crosslinking agent is not particularly limited, an isocyanate-based compound can be suitably used. In addition, since the electromagnetic wave has higher isolation, it is preferable that the adhesive contains the aforementioned metal which may be contained in the metal-containing resin coating layer. In this case, the range of the amount of the added metal is the same as that of the metal-containing resin coating layer. The adhesive may be provided in a dot shape, or it may be formed in a thin film shape so as to provide the entire area between the metal-containing resin coating layer and the wallpaper substrate. 169 -10- (7) (7) 200409588 It is also possible to pre-apply adhesive or adhesive to the contact surface with the wall in the electromagnetic wave isolation wallpaper as required. If an adhesive or an adhesive is provided, the gluing operation when attaching to a wall can be omitted, and the construction can be easily performed. The surface to which the adhesive or the adhesive is applied may be the surface of the metal-containing resin coating layer, and may be the surface of the wallpaper substrate. A preferable form of the electromagnetic wave isolation wallpaper to which an adhesive or an adhesive is given includes an electromagnetic wave isolation wallpaper in which a metal-containing resin coating layer is formed on one side of the wallpaper base material, and the side where the metal-containing resin coating layer is not formed. The surface of the wallpaper substrate is formed with an adhesive layer composed of an adhesive. In addition, in an electromagnetic wave isolation wallpaper in which a metal-containing resin coating layer is formed on both sides, an adhesive layer may be formed on either side. However, in the case where a coating layer for wallpaper decoration to be described later is formed, it is preferable to provide an adhesive or an adhesive on the side opposite to the surface on which the coating layer for wallpaper decoration is formed. In addition, the electromagnetic wave-isolated wallpaper may be formed with a wallpaper coating layer on a wallpaper substrate, preferably a metal-containing resin coating layer, as required. If a coating layer for wallpaper decoration is formed, the new style will be improved. Although the coating layer for wallpaper decoration is made of a well-known resin or paper used for wallpaper, a vinyl chloride resin or polyethylene, an ethylene-vinyl acetate copolymer, polypropylene, or the like is preferred. If the constituents of the coating layer for wallpaper decoration are vinyl chloride resin or polyolefin, the appearance and texture of the wallpaper, texture, fire resistance, durability, relief pattern processing, or coloring are excellent in decoration. In order to exert these properties, the resin constituting the coating layer for wallpaper decoration may include a known additive such as plasticizer, flame retardant, and ultraviolet absorber (8) 200409588. In addition, due to the high cost of vinyl chloride resin, even if the cost of the coating layer for wallpaper decoration is increased, the resin component of the metal-containing resin coating layer is when the vinyl chloride resin is used for the coating layer for wallpaper decoration. Poly is better. Since a vinyl chloride resin solution or a polyolefin solution is soluble in polyurethane, a vinyl chloride resin solution or the like can be applied to a metal-containing resin film containing a polyurethane resin. Therefore, the details of the manufacturing method can be simply provided with a wallpaper layer on the metal-containing resin coating layer. In addition, if the vinyl chloride resin solution is applied to a metal foil such as aluminum foil, the resin solution is rejected on the foil, so the solution cannot be used. Therefore, it is not possible to directly provide a conductive film with a coating layer for a tree decoration on a conductive metal foil. In addition, if the coating layer for wallpaper decoration is a foam type, those who provide relief patterns such as embossed patterns or print on a gravure roll, auto screen, or meter Those of a nature can also. This electromagnetic wave isolation wallpaper has an electromagnetic wave isolation of 30 d B or more in the entire field of the electric field component in the range of 10 MHz to 1 GHz. If the electromagnetic wave electric field component in the range of 10MHz to 1GHz has an electromagnetic wave isolation performance of 3 OdB or more, it can be sufficiently isolated. Among them, 値 measured by the electromagnetic wave isolation performance method (electric field) of the electromagnetic wave isolation wallpaper.

Furthermore, since the metal-containing resin coating layer is made of a metal-containing resin component, it has flexibility, has almost no winding defect of the roll, and is excellent in workability. In addition, since this electromagnetic wave-isolated wallpaper does not leave traces of wrinkles or creases even if it is strongly bent or the like, the new style after construction is high. Furthermore, since there is no need to attach the conductive metal film to the worker, there is no need to hire a worker, and there is no need to cooperate with the worker's schedule, so the construction period can be shortened. The electromagnetic wave isolation room of the present invention is a room to which the above-mentioned electromagnetic wave isolation wallpaper is attached. In order to make full use of electromagnetic wave isolation, it is better to attach electromagnetic wave isolation wallpaper to the wall. However, it is better to take appropriate and necessary treatment according to the required electromagnetic wave isolation performance for the sockets of windows, doors, and wires. Furthermore, if a reinforcing tape with electromagnetic wave isolation performance is used in the seam (butt joint) of the electromagnetic wave isolation wallpaper, the electromagnetic wave isolation chamber's robust isolation performance can be improved. This reinforcing tape can be placed anywhere between the base material of the wallpaper and the base material of the wall such as gypsum board or concrete wall, the surface of the coating layer for wallpaper decoration, and the surface of the resin layer containing metal. From the viewpoint of new style, it is better to place the reinforcing tape in a place that is not in contact with the eyes, for example, it is better to place it between a gypsum board and a wallpaper substrate. From the viewpoint of electromagnetic wave isolation, it is preferable to use a conductive tape or the like made of a conductive material for the reinforcing tape, and to connect the metal-containing resin coating layers of the electromagnetic wave isolation wallpaper with low resistance to each other. The conductive tape is made of a conductive metal or a conductive carbon-containing resin film layer or metal foil containing gold-13 · (10) (10) 200409588. As a result, an electromagnetic wave isolation chamber having an electromagnetic wave isolation performance of 3 OdB or more can be manufactured in the entire region of the electromagnetic wave electric field component in the range of 10 MHz to 1 GHz. Among them, the seam (butt joint) of the electromagnetic wave isolation wallpaper may be a seam of one piece of electromagnetic wave isolation wallpaper, and the seam of a plurality of pieces of electromagnetic wave isolation wallpaper may be used. In addition, even if the metal-containing resin coating layers of the seams (butt joints) of the electromagnetic wave isolation wallpaper are not connected with a conductive material, the isolation reinforcing tape is not used, and in the region of 10MHz to 1GHz, especially in the region of 25MHz to 1GHz. An electromagnetic wave isolation chamber having an electromagnetic wave isolation performance of more than 1 OdB, especially more than 20 dB can be produced in the entire range of the electromagnetic field components of the electromagnetic wave. In addition, this point does not mean that the electromagnetic wave isolation performance of 1 OdB or more is not found in areas other than the 10 MHz to 1 GHz area. That is, an electromagnetic wave isolation chamber having an electromagnetic wave isolation performance of 10 dB or more can be produced even in a region other than the 10 MHz to 1 GHz region, especially a region less than 10 MHz and a region between 1 GHz and 10 GHz. As described above, even if the metal-containing resin coating layers of the seams of the electromagnetic wave isolation wallpaper are not connected with a conductive material, an electromagnetic wave isolation chamber with excellent electromagnetic wave isolation performance can be obtained because the electromagnetic wave isolation wallpaper has excellent electromagnetic wave isolation and electromagnetic wave isolation. The wallpaper is soft, it is not easy to generate wrinkles, and the shape maintainability is small, so it is easy to construct, and there is almost no gap in the butt joint. Among them, the electromagnetic wave isolation performance of the electromagnetic wave isolation chamber is measured in accordance with Mil standard 285. This electromagnetic wave isolation room is affixed with the above-mentioned electromagnetic wave isolation which is excellent in workability. -14- (11) (11) 200409588 The room away from the wallpaper has excellent workability of the electromagnetic wave isolation wallpaper, so the size can be increased. If a large-sized electromagnetic wave is used to isolate the wallpaper, the number of seams in the wallpaper can be reduced, and as a result, the electromagnetic wave isolation of the electromagnetic wave isolation chamber can be improved. In the case of using an electromagnetic wave isolation wallpaper without a coating layer for wallpaper decoration, in order to improve the new style, after attaching the electromagnetic wave isolation wallpaper to the wall, it is also possible to provide a decoration layer on the electromagnetic wave isolation wallpaper. In addition, although a commonly used adhesive can be used when attaching an electromagnetic wave isolation wallpaper to a wall, the use of a conductive adhesive can improve electromagnetic wave isolation. Next, a method for manufacturing the electromagnetic wave isolation wallpaper of the present invention will be described. This manufacturing method is a process for forming a metal-containing resin coating layer having a metal-containing resin coating layer formed on a wallpaper substrate. As a method for forming a metal-containing resin coating layer on a wallpaper substrate, the following method can be adopted. (1) Coating a metal-containing resin solution on a release paper, drying, and forming a metal-containing resin coating layer, and then applying a gravure coater, a tube coater, and a doctor blade coating on the metal-containing resin coating layer. A known processing machine such as a cloth machine applies a laminating agent, and a method of laminating a metal-containing resin film layer and a wallpaper base material by drying and thermocompression bonding as necessary. (2) A direct coating method in which a metal-containing resin solution is applied to a wallpaper substrate using a known processing machine such as a tube coater or a blade coater, and dried as necessary to form a metal-containing resin coating layer. (3) Extrude the molten metal-containing resin into a T-die (T-15-15 (12) (12) 200409588 die), etc., and laminate the extruded metal-containing resin on the wallpaper base. Melt lamination on wood. Accordingly, by forming a metal-containing resin coating layer on a wallpaper substrate, it is possible to easily manufacture an electromagnetic wave-isolated wallpaper. In particular, in the case of the lamination method (1), since the metal-containing resin coating layer can be thin and uniform ', it has high electromagnetic wave isolation even if it is thin' and it can improve flexibility. In addition, since the heat treatment described later can be performed, the electromagnetic wave isolation can be further improved. In this manufacturing method, it is preferable that the metal-containing resin coating layer is heat-treated at least once or more. If it has a heating process, the dimensional stability of the electromagnetic wave isolation wallpaper and the contact area between conductive metals can be increased to reduce the surface resistance. If the heating process is after forming a metal-containing resin coating layer, it can be performed at any timing, for example, at the same time as the metal-containing resin coating layer forming process or the wallpaper coating layer forming process described later. However, it is better to use the coating layer forming process before wallpaper decoration. Since the heating temperature in the heating process does not consume excessive energy, it can improve electromagnetic wave isolation, so 50 ~ 200 ° C is preferable, and 100 ~ 200 ° C is more preferable. It is more preferable because the electromagnetic wave isolation is further improved. Therefore, it is better to use a pressing method such as stamping or calendering (c a 1 e n d e r) processing during the heating process. Among them, it is preferable to perform the pressure treatment and the heat treatment simultaneously. Furthermore, 'the effect of the heat treatment is particularly exerted, so the heat treatment is preferably performed at a heating temperature of 50 to 150 ° C and the heat treatment is performed at a heating temperature of 50 to 2 0 ° C. Furthermore,' this manufacturing method may A wall having a coating layer for providing wallpaper decoration. (16) (13) (13) 200409588 A coating layer forming process for paper decoration. In this process for forming a coating layer for wallpaper decoration, the following known methods (4) to (6) can be adopted. (4) On one side of the electromagnetic wave-isolated wallpaper manufactured by the methods (1) to (3), a known processing machine such as a tube coater or a blade coater is used to impart a resin solution for wallpaper decoration in accordance with Direct coating method that needs to be dried to form a coating layer for wallpaper decoration. (5) After coating the resin solution for wallpaper decoration on the release paper and drying to form a coating layer for wallpaper decoration, a gravure coater, a tube coater, and a blade coater are used on the wallpaper coating layer. A laminating method in which a known processing machine is used to apply an adhesive, and is dried as necessary, and is thermally compression-bonded to one surface of the electromagnetic wave insulation wallpaper manufactured by the methods (1) to (3). (6) A lamination method in which a resin for wallpaper decoration in a molten state is extruded onto a T-die or the like and laminated on one side of the electromagnetic wave-isolated wallpaper manufactured by the methods (1) to (3) above. . Furthermore, the electromagnetic wave isolation wallpaper manufactured by applying the coating layer for wallpaper decoration by (4) to (6) without further performing the processing of (7) or (8) below can further improve the new style of the electromagnetic wave isolation wallpaper. (7) A well-known printing system such as a gravure roll, an automatic fluorescent screen, an inkjet printer, or the like is applied to the coating layer for wallpaper decoration to impart printing properties. (8) Heat treatment at 170 ~ 240 ° C for 1 minute to 3 minutes. After the coating layer for wallpaper decoration is foamed, embossed pattern processing is performed at 1 80 ~ 220 ° C to impart unevenness. However, there is a reduction in electromagnetic wave isolation due to the nature of the embossed pattern, so it is better to implement a pattern that does not reduce the electromagnetic wave isolation. • 17- (14) (14) 200409588 In addition, a commercially available wall paper made of vinyl chloride resin, polyolefin, or paper can be used as a coating layer for wallpaper decoration. A known process such as a gravure coater, a tube coater, or a bar coater is used on the metal-containing resin layer of the above-mentioned electromagnetic wave-isolated wallpaper of (1) to (3) or on the back of a commercially available wallpaper. The adhesive is applied to the machine and dried as required. The electromagnetic wave-isolated wallpaper and the commercially available wallpaper can be bonded, and the coating layer for wallpaper decoration can also be provided. With such a coating layer forming process for wallpaper decoration, the new style of electromagnetic wave isolation wallpaper can be further improved. [Examples] Next, the present invention will be described in more detail with reference to examples. (Example 1) 60% by mass of 36% by mass scale-like silver particles (average major diameter 6 μm, average minor diameter 2 // m) and 4% by mass of polyurethane resin and N, N-diamine were prepared. A mixed molten coal (30% by mass DMF / 70% by mass TOL) of a silver-containing polyurethane resin solution composed of methylformamide (DMF) / toluene (TOL). Second, the dried metal-containing resin coating layer The thickness is 10 // m, and the silver-containing polyurethane resin solution is coated on a release paper by an ammunition barrel coater and dried at 120 ° C for 3 minutes to form a metal-containing resin coating layer. This metal-containing The silver content in the resin coating layer was 90.0% by mass. Next, an adhesive consisting of 30% by mass of a two-component polyurethane resin, 12% by mass of a crosslinking agent, and 58% by mass of methyl ethyl ketone (MEK) solvent was prepared. 18- (15) 200409588 Next, the thickness of the metal-containing resin coating layer and the adhesive layer after drying is 15 #m, and the adhesive is coated on the metal-containing resin coating layer by a bomb coater. Dry at 20 ° C for 3 minutes to form a joint. In addition, an adhesive layer (per m3) of 15 0g is not used as a wallpaper substrate on the adhesive layer. Next, a laminated processed product was obtained at a temperature of 120 ° C and a pressure of 0.4 MPa. The laminated processed product was placed in a ring at 60 ° C, and the adhesive was hardened sufficiently, and then the laminated strength was peeled from the release paper. An electromagnetic wave isolation wallpaper was obtained. The obtained electromagnetic wave isolation wallpaper was evaluated as follows. ≪ Surface resistance of the metal-containing resin coating layer > Measurement was performed using Lores.ta-EP (manufactured by Mitsubishi Chemical). ≪ Electromagnetic wave isolation of electromagnetic wave isolation wallpaper Performance> KEC method (electric field) is used to maintain the shape in the region of 10 MHz to 1 GHz. ≪ Maintenance of the shape > The electromagnetic wave isolation wallpaper is made into a roll shape for transportation.
