Description
【０００１】[0001]
本考案はケーブルなどに巻回して使用する電磁波シールド用テープに関する。 The present invention relates to an electromagnetic wave shielding tape which is wound around a cable or the like and used.
【０００２】[0002]
従来から、ＯＡ機器内部や他の機器との信号伝送用にケーブルを使用している が、電磁波によるノイズなどの悪影響を防止するために、銅やアルミニウムの金 属箔テープを巻回していた。しかしながら、この方法では電磁波シールドするこ とはできるものの、金属箔テープがＯＡ機器内部の他の部分と接触することによ り短絡し、誤動作の原因となるという問題があった。 Conventionally, cables have been used for signal transmission inside OA equipment and with other equipment, but in order to prevent the adverse effects of noise such as electromagnetic waves, copper or aluminum metal foil tape has been wound. However, although this method can shield electromagnetic waves, there is a problem in that the metal foil tape comes into contact with other parts inside the OA equipment to cause a short circuit and cause a malfunction.
【０００３】 そのため、金属箔テープを巻回した後、更に絶縁体シートを巻回して短絡を防 ぐ方法も知られているが、２回巻回する必要があるため作業上煩雑であった。Therefore, a method is known in which a metal foil tape is wound and then an insulating sheet is further wound to prevent a short circuit. However, it is necessary to wind twice, which is complicated in terms of work.
【０００４】 一方、実開平３−３４０４０号には長尺プラスチックシートの片面に粘着剤を 塗布し、金属或いは炭素の粉粒体を部分的に貼着した電磁波シールド用テープが 開示されている。しかしながら、この電磁波シールド用テープはプラスチックシ ートを使用しており、テープ間の導電性がないため、導電方向はプラスチックシ ートの巻回方向であり、しかも導電性をもたせているのが粉粒体であるため、導 電性が悪く、全体として電磁波シールド性に問題があるものであった。On the other hand, Japanese Utility Model Laid-Open No. 3-34040 discloses an electromagnetic wave shielding tape in which a pressure-sensitive adhesive is applied to one surface of a long plastic sheet and metal or carbon particles are partially adhered. However, since this electromagnetic wave shielding tape uses plastic sheets and there is no electrical conductivity between the tapes, the conducting direction is the direction in which the plastic sheets are wound and the electrical conductivity is imparted. Since it was a granular material, it had poor electrical conductivity and had problems with electromagnetic wave shielding as a whole.
【０００５】[0005]
本考案は上記の問題点を解決するためになされたものであり、短絡防止、電磁 波シールド性、更には作業性に優れた電磁波シールド用テープを提供することを 目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an electromagnetic wave shielding tape excellent in short-circuit prevention, electromagnetic wave shielding property, and workability.
【０００６】[0006]
本考案はテープ状の多孔性基材１が、長手方向に連続した導電領域２と絶縁領 域３とを有している電磁波シールド用テープであり、電磁波シールド用テープの 空隙に粘着剤５が付着していればより作業性に優れる。 The present invention is an electromagnetic wave shielding tape in which a tape-shaped porous substrate 1 has a conductive region 2 and an insulating region 3 which are continuous in the longitudinal direction, and an adhesive 5 is provided in a gap of the electromagnetic wave shielding tape. If it is attached, the workability is better.
【０００７】[0007]
本考案を図１〜図３を参照しながら説明すると、本考案はテープ状の多孔性基 材１（以下、多孔性基材１という）からなり、多孔性基材１の長手方向に連続し た導電領域２と、絶縁領域３とを有するものであり、本考案の電磁波シールド用 テープ４をケーブル６などに、導電領域同士が接触し、しかも導電領域２が絶縁 領域３によって覆い隠されるように巻回すると、導電領域同士が接触しているた め導電性が得られ、導電加工したシートを巻回した状態と同じになるため、電磁 波シールド性に優れている。また、導電領域２が絶縁領域３によって覆い隠され るように巻回されているため、外側は絶縁領域同士が接触し、絶縁体シートを巻 回した状態と同じになるため、ＯＡ機器内部の他の部分と接触しても、短絡して 誤動作を生じることがない。 The present invention will be described with reference to FIGS. 1 to 3. The present invention comprises a tape-shaped porous substrate 1 (hereinafter referred to as porous substrate 1), which is continuous in the longitudinal direction of the porous substrate 1. It has a conductive area 2 and an insulating area 3, so that the electromagnetic wave shielding tape 4 of the present invention is brought into contact with the cable 6 and the like, and the conductive area 2 is covered by the insulating area 3. When the sheet is wound around, the conductive areas are in contact with each other, so that conductivity is obtained, and the sheet becomes the same as when the sheet that has been subjected to the conductive processing is wound, so that it has excellent electromagnetic wave shielding properties. Moreover, since the conductive region 2 is wound so as to be covered by the insulating region 3, the insulating regions are in contact with each other on the outer side, and the state is the same as when the insulating sheet is wound. Even if it makes contact with other parts, it does not cause a short circuit and malfunction.
【０００８】 また、本考案の電磁波シールド用テープ４はケーブル６などに１枚巻回するの みで、導電加工したシートと絶縁体シートの２枚を巻回した場合と同等の構造と なり、同様の効果が得られるので、作業性にも優れたテープである。Further, since the electromagnetic wave shielding tape 4 of the present invention is wound only once around the cable 6 or the like, it has the same structure as when two sheets of a conductive processed sheet and an insulator sheet are wound, Since the same effect can be obtained, the tape has excellent workability.
【０００９】 更に、この電磁波シールド用テープ４の空隙に粘着剤５が付着していれば、電 磁波シールド用テープ４をケーブル６などに巻回すると同時に、ケーブル６およ び主として導電領域２に粘着固定でき、電磁波シールド用テープ４の両端を固定 する手間を省くことができるので、より作業性に優れた電磁波シールド用テープ ４となる。Further, if the adhesive 5 is attached to the voids of the electromagnetic wave shielding tape 4, the electromagnetic wave shielding tape 4 is wound around the cable 6 and the like, and at the same time, the cable 6 and mainly the conductive region 2 are wound. Since the adhesive tape can be fixed and the labor for fixing the both ends of the electromagnetic wave shielding tape 4 can be omitted, the electromagnetic wave shielding tape 4 is superior in workability.
【００１０】 本考案の電磁波シールド用テープ４（以下、テープ４という）を構成する多孔 性基材１として、織物、編物、不織布などを使用することができる。これら多孔 性基材１を使用し、導電加工を施すことにより導電領域を形成すると、テープ４ の長手方向のみではなく、テープ４の厚み方向も導電加工され、厚み方向にも導 電性が得られるので、テープ４をケーブル６などに巻回すると、導電加工した１ 枚のシートを巻回した状態と同等の状態となるため、電磁波シールド性に優れる 。A woven fabric, a knitted fabric, a non-woven fabric, or the like can be used as the porous base material 1 constituting the electromagnetic wave shielding tape 4 (hereinafter, referred to as tape 4) of the present invention. When these porous base materials 1 are used to form a conductive region by conducting a conductive process, not only the longitudinal direction of the tape 4 but also the thickness direction of the tape 4 is subjected to the conductive process, and the conductive property is obtained in the thickness direction. Therefore, when the tape 4 is wound around the cable 6 or the like, the state becomes equivalent to the state in which a single sheet subjected to conductive processing is wound, so that the electromagnetic wave shielding property is excellent.
【００１１】 本考案の多孔性基材１に使用する繊維は特に限定するものではなく、例えば、 絹、羊毛、綿、麻、石綿などの天然繊維、レーヨン繊維などの再生繊維、アセテ ート繊維などの半合成繊維、ポリアミド繊維、ポリビニルアルコール繊維、アク リル繊維、ポリエステル繊維、ポリ塩化ビニリデン繊維、ポリ塩化ビニル系繊維 、ポリウレタン繊維、ポリエチレン繊維、ポリプロピレン繊維などの合成繊維を 使用することができる。なお、上記の繊維のように一成分からなる繊維のみでは なく、２成分以上からなり、断面形状が芯鞘型、サイドバイサイド型、海島型、 バイメタル型、菊花型などの複合繊維を使用しても良い。The fibers used in the porous substrate 1 of the present invention are not particularly limited, and examples thereof include natural fibers such as silk, wool, cotton, hemp, and asbestos, regenerated fibers such as rayon fibers, and acetate fibers. Semi-synthetic fibers such as, polyamide fibers, polyvinyl alcohol fibers, acrylic fibers, polyester fibers, polyvinylidene chloride fibers, polyvinyl chloride fibers, polyurethane fibers, polyethylene fibers, polypropylene fibers, and other synthetic fibers can be used. It should be noted that not only the fibers made of one component like the above-mentioned fibers, but also the composite fibers made of two or more components and having a cross-sectional shape of a core-sheath type, side-by-side type, sea-island type, bimetal type, chrysanthemum type, etc. good.
【００１２】 これらの繊維を使用して織物、編物、不織布などを形成するが、ケーブル６な どに巻回した際に伸縮性のない織物、不織布が好適に使用できる。織物としては 特に限定するものではなく、平織、綾織、朱子織で良く、不織布としても湿式法 、乾式法、紡糸と同時に不織布とする直紡法によって形成すれば良く、特に限定 するものではない。A woven fabric, a knitted fabric, a non-woven fabric or the like is formed by using these fibers, and a woven fabric or non-woven fabric having no elasticity when wound around the cable 6 can be preferably used. The woven fabric is not particularly limited, and may be a plain weave, a twill weave, or a satin weave. The non-woven fabric may be formed by a wet method, a dry method, or a direct spinning method in which a nonwoven fabric is formed at the same time as spinning, and is not particularly limited.
【００１３】 なお、本考案のテープ４はケーブル６などに巻回して使用するため、使用する ケーブル６によってテープ４の幅、長さ、厚みを適宜変化させれば良く、特に限 定するものではない。Since the tape 4 of the present invention is used by being wound around the cable 6 or the like, the width, length, and thickness of the tape 4 may be appropriately changed depending on the cable 6 to be used, and it is not particularly limited. Absent.
【００１４】 本考案のテープ４は前記のような多孔性基材１の長尺方向に連続した導電加工 を施すことにより、導電領域を形成し、長尺方向は勿論のこと、厚み方向にも導 電性をもつ。The tape 4 of the present invention forms a conductive region by continuously conducting the conductive material in the lengthwise direction of the porous substrate 1 as described above, and in the lengthwise direction as well as in the thickness direction. It has conductivity.
【００１５】 本考案の導電加工としては、金属メッキ処理、蒸着処理、スパッタリング処理 、イオンプレーティング、金属溶射、導電性ポリマーによる被覆処理などの導電 性を付与する方法であれば良く、特に限定するものではないが、金属メッキ処理 、特に、無電解メッキ処理により導電加工すれば、多孔性基材１の内部もメッキ されやすく、厚み方向の導電性にも優れているため、好適に使用できる。The conductive processing of the present invention is not particularly limited as long as it is a method for imparting conductivity such as metal plating treatment, vapor deposition treatment, sputtering treatment, ion plating, metal spraying, coating treatment with a conductive polymer, and the like. Although not a matter of course, if the conductive processing is performed by a metal plating treatment, especially an electroless plating treatment, the inside of the porous substrate 1 is easily plated, and since the conductivity in the thickness direction is excellent, it can be preferably used.
【００１６】 無電解メッキの方法としては、(1)ロールコーター法などにより導電領域２に 該当する領域に、塩化スズ溶液などを塗布した後、塩化パラジウムなどを塗布し てパラジウム金属などをスズカチオンなどと結合させた後に、メッキ浴中に浸漬 することによりメッキする方法、(2)パラジウムなどの触媒作用をする金属とポ リビニルアルコールなどのような高分子との錯体をロールコーター法などによっ て導電領域２に該当する領域に塗布した後、メッキ浴中に浸漬してメッキする方 法、(3)ポリビニルアルコールのように水で溶解除去できるような、溶剤によっ て除去できる高分子をロールコーター法などで、絶縁領域３に該当する領域に塗 布し、塩化スズ水溶液などと接触させた後、塩化パラジウム水溶液などと接触さ せてパラジウム金属などをスズカチオンなどと結合させた後、高分子を溶剤除去 することにより、触媒を担持しない領域を形成させた多孔性基材１をメッキ浴中 に浸漬してメッキする方法などを例示できるが、これらに限定されるものではな い。The electroless plating method includes (1) applying a tin chloride solution or the like to a region corresponding to the conductive region 2 by a roll coater method or the like, and then applying palladium chloride or the like to a palladium metal or the like with a tin cation or the like. After being combined with the metal, it is plated by immersing it in a plating bath. (2) A roll coater method is used to form a complex of a metal such as palladium and a polymer such as polyvinyl alcohol as a catalyst. After applying to the area corresponding to the conductive area 2, the method of plating by immersing in a plating bath, (3) Polymer that can be removed by a solvent, such as polyvinyl alcohol, can be dissolved and removed with water. Use a roll coater method or the like to apply it to the area corresponding to the insulating area 3, and after contacting it with an aqueous solution of tin chloride, etc., contact it with an aqueous solution of palladium chloride, etc. For example, a method may be exemplified in which, after binding a metal such as tin with a cation such as tin, the polymer is removed by a solvent to immerse the porous substrate 1 in which a region not supporting a catalyst is formed in a plating bath for plating. However, it is not limited to these.
【００１７】 なお、触媒をロールコーター法により担持させる場合、多孔性基材１の導電領 域に該当する領域のみに付着させても良いし、導電領域の２倍幅に該当する領域 に付着させても良く、特に限定するものではない。なお、後者の場合、２倍幅に 該当する領域の真ん中の所で切断すれば、２枚のテープが得られ、裁断すること により、導電領域の端が真っ直ぐであり、しかも無駄がないので、より好ましい 触媒の担持方法である。When the catalyst is supported by the roll coater method, the catalyst may be attached only to the region corresponding to the conductive region of the porous substrate 1, or may be attached to the region corresponding to twice the width of the conductive region. However, there is no particular limitation. In the latter case, two tapes can be obtained by cutting in the middle of the area corresponding to the double width, and by cutting, the ends of the conductive area are straight and there is no waste. It is a more preferable method of supporting the catalyst.
【００１８】 このように導電加工を施すことにより、導電領域２が形成されるが、同時に導 電加工の施されていない絶縁領域３も形成される。この絶縁領域３はケーブル６ などに巻回した場合に、表面を１枚の絶縁体シートで覆った時と同様の状態にな るため、短絡するという問題が生じない。By applying the conductive processing in this manner, the conductive area 2 is formed, but at the same time, the insulating area 3 not subjected to the conductive processing is also formed. When the insulating region 3 is wound around the cable 6 or the like, it is in the same state as when the surface is covered with one insulating sheet, so that the problem of short circuit does not occur.
【００１９】 本考案における導電領域２と絶縁領域３の幅の比が１：１の場合、導電領域２ と絶縁領域３が同じ幅であるため、ケーブル６などに巻回すると、導電領域同士 或いは絶縁領域同士の重なる幅も等しく、導電領域２、絶縁領域３共に効率よく 接触するので、最も好ましいが、導電領域２と絶縁領域３の幅の比が１：１であ る必要はなく、ケーブル６の種類などによって適宜変化させれば良い。When the width ratio of the conductive region 2 and the insulating region 3 in the present invention is 1: 1, since the conductive region 2 and the insulating region 3 have the same width, when wound around the cable 6 or the like, the conductive regions 2 or Since the overlapping widths of the insulating regions are equal and the conductive regions 2 and 3 are in efficient contact with each other, it is most preferable, but the width ratio of the conductive regions 2 and the insulating regions 3 need not be 1: 1. It may be appropriately changed depending on the type of 6 and the like.
【００２０】 以上のようにして得られる本考案のテープ４は、ケーブル６などに導電領域同 士が接触すると共に、絶縁領域３によって導電領域２を覆い隠すように巻回する と、導電加工したシートと絶縁体シートの２枚のシートで覆った状態と同じ状態 になるため、電磁波シールド性に優れ、短絡の生じないテープ４であり、作業性 にも優れたものである。The tape 4 of the present invention obtained as described above is subjected to conductive processing when the conductive area member is brought into contact with the cable 6 and the insulating area 3 is wound so as to cover the conductive area 2. Since it is in the same state as when it is covered with two sheets, the sheet and the insulator sheet, the tape 4 has excellent electromagnetic wave shielding properties and does not cause a short circuit, and also has excellent workability.
【００２１】 本考案のテープ４の空隙に粘着剤５を付着させれば、テープ４を巻回すると同 時に粘着固定できるので、より作業性に優れたテープ４である。なお、この場合 、使用する際の押圧により、空隙に付着していた粘着剤５がテープ表面に滲み出 るが、粘着剤５が滲みでる前に、導電領域の繊維は重なる導電領域の繊維と既に 接触しているので、滲み出る粘着剤５により導電性が妨げられるということはな い。If the adhesive 5 is attached to the voids of the tape 4 of the present invention, the tape 4 can be adhesively fixed at the same time as the tape 4 is wound, so that the tape 4 has better workability. In this case, the pressure-sensitive adhesive during use causes the adhesive 5 adhering to the voids to ooze out onto the tape surface, but before the adhesive 5 oozes out, the fibers in the conductive area overlap with the fibers in the conductive area that overlap. Since they are already in contact, the exuding adhesive 5 does not hinder the conductivity.
【００２２】 本考案の粘着剤５としては、アクリル酸エステル系ゴム、天然ゴム、シリコン 系ゴム、ポリクロロプレン、ブタジエン−スチレン共重合体、エチレン−酢酸ビ ニル共重合体、ポリイソブチレン、ポリビニルエーテル系ゴムなどの溶剤型、エ マルジョ型、付加反応型の粘着剤５を使用することができ、特に限定するもので はない。As the adhesive 5 of the present invention, acrylic ester rubber, natural rubber, silicone rubber, polychloroprene, butadiene-styrene copolymer, ethylene-vinyl acetate copolymer, polyisobutylene, polyvinyl ether type A solvent type adhesive such as rubber, an emulsion type or an addition reaction type pressure-sensitive adhesive 5 can be used and is not particularly limited.
【００２３】 粘着剤５の付着方法としては、粘着剤５を多孔性基材１に含浸したり、塗布し たり、スプレーした後、圧力を加えてテープ４の空隙に粘着剤５を押し込めば良 い。なお、粘着剤５はテープ４の空隙全体に付着させても、空隙の一部にのみ付 着させても良い。また、粘着剤５は片面のみでも両面でも良いが、両面に粘着剤 ５を付着させると、ケーブル６などに巻回した際の絶縁領域３にも粘着性がある ことになり、取り扱いにくいので、片面のみに付着させるのが好ましい。As a method of attaching the pressure-sensitive adhesive 5, the pressure-sensitive adhesive 5 may be impregnated into the porous substrate 1, applied, or sprayed, and then pressure may be applied to push the pressure-sensitive adhesive 5 into the gap of the tape 4. Yes. The adhesive 5 may be attached to the entire void of the tape 4 or may be attached only to a part of the void. Also, the adhesive 5 may be on one side or on both sides, but if the adhesive 5 is attached to both sides, the insulating region 3 when it is wound around the cable 6 or the like also has adhesiveness and is difficult to handle. It is preferable to attach it only on one side.

本考案の電磁波シールド用テープは長手方向に連続した導電領域と、絶縁領域 とを形成しているため、ケーブルなどに導電領域同士が接触し、しかも導電領域 を絶縁領域で覆い隠すように巻回すると、導電加工したシート１枚を巻回した状 態と同じになるため、電磁波シールド性に優れている。また、絶縁領域同士も接 触しており、１枚の絶縁体シートを巻回した状態と同じになるため、ＯＡ機器内 部の他の部分と接触しても、短絡して誤動作を生じることがない。 Since the electromagnetic wave shielding tape of the present invention forms a conductive area and an insulating area which are continuous in the longitudinal direction, the conductive areas are in contact with each other such as a cable, and moreover, the conductive area is wound so as to be covered by the insulating area. Then, the state is the same as the state in which one sheet that has been subjected to conductive processing is wound, so that it has excellent electromagnetic wave shielding properties. In addition, since the insulating areas are also in contact with each other and the situation is the same as when one insulating sheet is wound, even if it makes contact with other parts inside the OA equipment, it may cause a short circuit and malfunction. There is no.
【００４３】 また、本考案の電磁波シールド用テープは１枚巻回するのみで、導電加工した シートと絶縁体シートの２枚を巻回した場合と同等の状態にあり、同様の効果が 得られるので、作業性にも優れている。Further, the electromagnetic wave shielding tape of the present invention is wound only once and is in a state equivalent to the case where two sheets of a conductive processed sheet and an insulating sheet are wound, and the same effect can be obtained. Therefore, it has excellent workability.
【００４４】 なお、本考案の電磁波シールド用テープの空隙に粘着剤が付着していれば、巻 回と同時に粘着固定できるため、より作業性に優れている。If the adhesive is adhered to the voids of the electromagnetic wave shielding tape of the present invention, it can be adhered and fixed at the same time as the winding, and thus the workability is further improved.
