According to another embodiment of the present invention, a method for preparing an electrically conductive tape is provided, the method comprising the steps of: forming a mesh-type elastic support layer having an open space; laminating an electrically conductive layer on the mesh-type elastic support One surface of the layer, and a conductive adhesive applied to the other surface of the mesh-type elastic support floor to form a conductive adhesive layer. [Embodiment] Hereinafter, the present invention will be described in detail. In the present invention, the term "open space" refers to an unoccupied space that penetrates the entire surface upward/downward, such as a mesh of a mesh type fabric, or a through hole of an elastic polymer sheet. Fig. 1 shows an example of an electromagnetic wave shielding plate according to an embodiment of the present invention. The electrically conductive tape shown in Fig. 1 has a mesh-type elastic supporting layer 丨 having an electric layer 2 laminated on one surface thereof, and a conductive adhesive layer 3 disposed on the other surface. 200914574 * According to the electrically conductive tape of the present invention, the electrically conductive adhesive layer 3 is in contact with the electrically conductive layer (10) = the open space of the perforated elastic support layer 1, so that the adhesive can be electrically bonded to the other surface. Therefore, the electrically conductive tape of the present invention shields or absorbs electromagnetic waves generated by an electronic device. 5 10 15 ★ The electrically conductive tape of the present invention comprises a mesh-type elastic support layer i which is self-shocking or vibrating. For example, a mesh type fabric can be used for the mesh type elastic support here. The woven mesh pattern of the present invention is not limited, and the sifting mesh type fabric is made of a yarn, and is similar to a mesh-like loosely woven fabric, that is, using the interlaced warp yarn. A woven fabric in which mesh openings are formed at predetermined intervals may be used. Examples of the yarn include: a spun yarn made of a day-dimensional, such as cotton, wool, hemp, etc.; a fine yarn made of natural fibers such as silk; and a rayon, a nylon, Single fine wire fried or multi-filament yarn made of polyethylene, polyester, polyurethane, etc. According to an embodiment of the present invention, a mesh type fabric in which a fine yarn is interlaced in a warp and weft direction can be used to form an elastic support layer. Such a mesh type fabric has a mesh hole formed therein. Here, the ratio of the mesh holes is not particularly limited. However, according to an embodiment of the present invention, the ratio of the holes W forms a mesh opening. The corresponding soil also has an open space of about 1 〇 to 8 〇% with respect to the entire surface area, and the conductive adhesive layer 3 is in contact with the electrically conductive layer 2 through the open space, so that the adhesive tape can be electrically connected. One surface to the other. In addition to the mesh type fabric, the mesh type elastic support 1 may also use a polymer sheet having through holes formed therein at predetermined intervals. The polymer sheet used in the present invention 20 200914574 is not limited as long as the polymer sheet is made of an elastic material which protects the electronic device from impact or vibration. Examples of the polymer sheet include: a polyethylene-based resin, a polypropylene-based resin, a polyvinyl chloride-based resin, and a polyvinylidene chloride. Polyvinylidene chloride-based resin, polystyrene-based resin, polyester-based resin, polyacrylic resin, styrene Styrene-acrylonitrile (SAN) copolymer, ethylene-vinyl alcohol copolymer (EVA resin), acrylonitrile-butadiene resin -styrene (ABS) resin), polyurethane-based resin, fluoro resin, silicon-based resin, but the invention is not limited thereto. 15 A polymer sheet made of the above polymer resin may include an open space in which through holes are formed at a predetermined interval. Preferably, the through holes are formed in a ratio of 1 to 1 boring/cm 2 , and in this way, the polymer sheet made of the polymer resin includes an open space of about 10 to 80% with respect to the entire surface area. Further, the diameter of each of the through holes is not particularly limited, but a preferred range is about 0.1 to 5 20 mm. Each of the through holes forms an angle of about 30 to 90 with its adjacent through holes. The through hole usually has a shape such as a circle, a triangle, or a square, and is not particularly limited. The thickness of the mesh-type elastic support layer can be adjusted according to the application of the tape to protect the electronic device or electronic components from shock or vibration. For example, in large-sized electronic devices, such as notebook computers, it is preferable to use a thicker elastic support layer 200914574; and a small-sized electronic device such as a mobile phone, preferably a resilient support layer. According to an embodiment of the present invention, the thickness of the _ hole type elastic supporting sound may be about 〜. 5 5 5 mm. The tooth "5 10 15 on the surface of the mesh-type elastic layer k - the surface of the conductive layer 2 is moved straight up. The conductive layer can be used - made of metal material that can be shielded or absorbed from the electrons and the electromagnetic waves generated The metal film is preferably made of metal. Unlike the conductive cloth used in the conventional electromagnetic wave shielding tape, the metal film used as the conductive layer is used in the tape, and even if the tape is cut, it is not easy to be metal particles or thin fibers. The conductive layer has a surface resistance of about Ο.ίΠ ohm/sq, which is purer than the conventional conductive cloth (about 0.04 ohm/sq) used in the conventional electromagnetic wave shielding tape, that is, the conductive layer has a high surface. Electronic conductivity. The tape of the present invention can have high magnetic wave shielding/absorption characteristics. Examples of metal materials include, but are not limited to, gold, platinum, silver, copper, aluminum, tin, nickel, and alloys thereof. In an embodiment, a metal foil made of aluminum can be used as the electrically conductive layer. The thickness of the electrically conductive layer can be easily adjusted as desired by those skilled in the art. According to an embodiment of the invention, the thickness of the electrically conductive layer The circumference is about 2 to 3 inches, preferably 3 to 100 /zm, more preferably 5 to 5 inches. The above-mentioned another type of the mesh type elastic support layer on which the electrically conductive layer is laminated is included. The surface of the conductive adhesive layer 3 is disposed here. The conductive adhesive layer 3 can be formed by coating a conductive adhesive on the other surface of the mesh-type elastic support layer 1. The conductive adhesive is not particularly limited as long as it is in the field. Conventional conductive adhesives can be used. - Generally speaking, 'conductive adhesives include: adhesive polymerization 20 200914574 5 10 15 grease? Electrical fillers, and other fillers. Conductive fillers are not scattered in the adhesive polymer resin Therefore, the conductive filler particles are distantly connected to form a continuous path. Since electrons can pass through the continuous passage, when the = Μ layer and the f-guide layer are opened through the mesh-type elastic support layer, the surface electrical conductivity of the tape of the present invention Connecting to another surface. Examples of the adhesive polymer resin that can be used for the conductive adhesive may include, but are not limited to, epoxy resin, polyester resin, acrylic resin, polyamido resin, polysulfone, phenol resin, Melamine resin and the like. For conductive fillers, 'available gold, platinum, silver, copper, aluminum, tin, nickel, carbon black, carbon fiber, graphite, p〇lyacety ene, polyaniline, polypyrox (p〇 Lypyrr〇ie), polythiophene, polythiazole (p〇iysuifurnitride), polyphenylene (P ypphenylene), polyphenylene sulfonate (polypyridylene), poly-P-phenyienevinylene, and A mixture thereof, but the present invention is not limited thereto. The filler based on the adhesive polymer resin may include a composition of about 1 G to a fine weight. The thickness of the conductive adhesive layer 3 is not particularly limited, but is preferably in the range of about $50 to 50 #m. If the thickness of the conductive adhesive layer is less than 5#, the adhesive strength of the tape will be weakened; if the thickness of the conductive adhesive layer is greater than 5〇#m, the conductivity will be weakened, and the electronic device applying the conductive adhesive layer to the dense component will Very difficult. Further, on the surface of the electrically conductive tape of the present invention, the relief pattern portion 4 may be formed in each open space of the mesh type elastic support layer 1 (see Figs. 3 and 4). Compared with the electromagnetic wave shielding tape of the portion without the ocean carving pattern, there is a relief 20 200914574 The pattern portion 4 is formed in the product mark, and has an improved drop:. Further, the second adhesive layer is improved by reducing irregularities and enthalpy, even when the electronic device has a flat surface, that is, a rough surface, : 5 10 15 due to the embossed pattern portion, it can be changed to a type ", π... Adhesive characteristics between the tweezers. Need to be individual = pattern ° 卩 4 The shape and depth can be made according to the tape in the case: Do not adjust. The shape of the part of the eagle pattern can include: concave hemisphere, the limit. According to this Embodiments of the invention, when the sieve shape = two sides: hole: bomb; carving branch =: temple, the shape of the relief figure part ^ the depth of the part of the carving pattern can be sieved? The thickness of the layer (10) is consistent, for example: About less than one:: Thus, as long as the embossed pattern portion is visible. <At the same time, the present invention provides a method for preparing an electrically conductive tape. «In the embodiment of the present invention, the tape can be: layer = hole The elastic support layer; the piezoelectric layer of the layer is on the mesh-type elastic support, and the other surface of the electro-adhesive L-mesh elastic-retaining layer is formed to form a conductive adhesive layer. Using the well-known methods in the field, The fabric is formed 'and then laminated on a sound surface of the mesh-type elastic support layer, and an electrically conductive layer made of a metal material is laminated.

After that, the mesh-type elastic support is pre-formed on the Γ-type elastic support layer. When the heated hot melt is heated, the layer of the surface of the elastic support layer is laminated. Thus, the conductive is The ^-type elastic support layer and the electrically conductive elastic support layer are additionally formed by coating a conductive adhesive on the other surface of the mesh hole, thereby obtaining a conductive knee band. Medium::= More specific example As shown in Fig. 5, a mesh type fabric in the winding_latitude-longitude direction is rolled up by a poly-yarn yarn in a two-two metal film. After that, it is known by the winding drum (8) core (10). Fabric i and Ming metal film cylinder 20 丨 and lower hot pressing roller 2 〇 2 ..., the wave-type fabric i - surface 乂 / then laminated to the mesh hole melt, with conductive or non-conductive heat to rob On the surface of the 4th port 1, the aluminum metal film 2 can be laminated on the mesh fabric 1 in a manner of soap. • After the private order, the other surface of the mesh-type fabric 1 is coated with a spray coating (the conductive adhesive is applied, thereby forming a conductive adhesive layer 3. In the case of conductive bonding) The agent is also applied to the mesh hole of the mesh-type fabric, and the conductive/adhesive layer may be in contact with the metal film, so that the surface of the tape can be electrically connected. Therefore, the conductance capable of shielding or absorbing electromagnetic waves can be obtained 12 200914574 and The present invention has the potential to be formed by using a layer step, which is used to form a conductive adhesive layer, which is rolled into the mesh-type elastic support layer, and is formed into a net-engraved pattern portion (see Fig. 6). Each of the open engraved pattern portions 4 of the dental layer may be 5 4 〇 2, and its surface is formed into two. The formation includes a raised roller cylinder 4 〇 1. In particular, the tape:::' and the rubber roller having a smooth surface are known in the field. The roller device can be used for the roller-scraping portion 4 of the roller device. The material "as shown in the table (4) is convex with a convex portion. For example, the oceanic pattern portion 4 can simply utilize the rubber roller 4 having a smooth outer peripheral surface. (HH has each (four) ^ bracketed part formed in its outer circumference 円 2, there is The convex shape of the convex tube and the rubber _ contact with the convex shape to form a 'bull roller drive, the tape, the cylinder 401 and the convex roller service a β m +, the surface of the crucible is laminated with the electrically conductive layer 2 and the other 15 (four) The mesh-type elastic support layer 1 of the layer 3 is passed between the rubber and the convex roller 402 and is interposed therebetween, and the convex portion and the rubber portion of the rubber roller 401 make the glue-surface The pressure generated between the rolling and the rubber roller is the embossed pattern portion 4 formed on the two sides. The embossing 20 ^ formed by the above method can prevent the occurrence of irregular marks on the conductive tape and improve the adhesion of the tape. The adhesive tape according to the present invention comprises a mesh-type elastic support layer having an electrically conductive layer laminated on one surface thereof and a conductive adhesive layer disposed on the other surface, which can be used for screening or absorbing electromagnetic waves generated from the electronic device. Through the open space of the mesh-type 13 200914574 elastic support layer, the electrically conductive layer is in contact with the electrically conductive adhesive layer, thereby electrically connecting one surface of the tape to the other surface.
