More specifically, in a double-sided tape used for shielding electromagnetic waves, the tape is composed of a conductive fiber material and also has a top and bottom adhesive force Conductive fiber double-sided tape for shielding electromagnetic waves with excellent durability by providing a structure that is different and maintains a constant adhesive strength without changing the adhesive strength due to changes over time, and continuously excellent electromagnetic shielding effect and a method of manufacturing the same will be.

최근 전자 통신 산업의 발달로 전자 기기, 전기 기기 및 모바일폰의 이용이 크게 확대되고 있으며, 이러한 각종 전자기기의 내부 회로에서는 전자파가 발생되어 공중을 통하여 외부로 방전되거나 전원선 등을 통해서 전도되고 있는데, 이러한 전자파는 주변의 부품 또는 기기에 노이즈와 오작동을 일으킬 우려가 있으며, 또한 인체에도 해로운 영향을 주는 것으로 알려져 있다. 더욱이, 최근 전자기기의 경박단소화, 디지털화로 인하여 회로가 복잡해지면서 전자파 발생 가능성이 급격히 증가하고 선진 각국은 물론 국내에서도 전자파의 규제가 강화되고 있는 실정이다.Recently, with the development of the electronic communication industry, the use of electronic devices, electric devices, and mobile phones has been greatly expanded. In the internal circuits of these various electronic devices, electromagnetic waves are generated and discharged to the outside through the air or conducted through power lines. In addition, such electromagnetic waves may cause noise and malfunction to surrounding components or devices, and are also known to adversely affect the human body. In addition, as the circuit becomes complicated due to the recent shortening and digitization of electronic devices, the possibility of electromagnetic wave is rapidly increasing, and the regulation of electromagnetic waves is strengthened not only in advanced countries but also in Korea.

따라서, 전자 기기 등으로부터 발생하는 전자파 장해에 대한 방지 대책이 점점 더 중요시되고 있다. 이러한 전자파는 전자기기에서 자체적으로 발생되던가, 아니면 외부에서 전자기기에 침입하며, 또한 접속되어 있는 회로선을 따라 전자파가 흘러들어가 각종 피해와 간섭을 주기도 한다. 이러한 전자파의 폐해를 해소하기 위해 전자파를 차단할 수 있는 것으로 다양한 방법들로 도전성 테이프가 제안되어 사용되어 왔는데 이러한 도전성 테이프는 재료의 올 풀림이나 버(burr)에 의한 문제가 있었으며 이를 해결하기 위해, 예를 들어 대한민국 특허출원 제2008-0039964호는 전자파 차폐용 초박막 도전 테이프 및 그 제조 방법에 관한 것으로, "저온 플라즈마 장치를 이용하여 진공 및 세척 처리된 후에 스퍼터 에칭 및 플라즈마 에칭 또는 코로나 방전 에칭에 의해 물리적 계면 처리되고, 전기전도성이 우수한 금속이 도금된 후에 단면 또는 양면에 도전성 점착제가 도포된 도전성 기재가 합지되어 있는 전자파 차폐용 초박막 도전 테이프로서, 일정한 간격으로 타공된 홀(hole)을 갖는 초박막 절연 필름 기재 층; 타공된 홀을 경계로 하여 상기 초박막 절연 필름 기재 층을 둘러싸고 있으며, 전기전도성이 우수한 금속이 전해, 무전해, 치환, 진공 증착 또는 스퍼터링 방식으로 도금된 하나 이상의 도금 층; 및 일면 또는 양면에 부착된 도전성 점착제 층을 포함하는 것을 특징으로 하는 전자파 차폐용 초박막 도전 테이프"를 개시하고 있다. 또 다른 예로는 대한민국 실용신안등록출원 제2005-0021299호는 전도성 양면 점착테이프로 "테이프에 있어서, 기재인 시트층과, 상기 시트의 상측에 코팅된 제 1 전도성 금속 페이스트 코팅층과, 상기 시트의 하측에 코팅된 제 2 전도성 금속 페이스트 코팅층과, 상기 제 1 전도성 금속 페이스트 코팅층에 합지된 제 1 전도성 점착제층과, 상기 제 2 전도성 금속 페이스트 코팅층에 합지된 제 2 전도성 점착제층 및 상기 제 2 전도성 금속 페이스트 코팅층에 합지된 제 2 전도성 점착제층의 타면에 합지된 이형지층으로 구성되어, 특정 기기 및 기구의 특정 부위에 점착 시 상하면을 통전하여 전기를 전도하고 전자파를 차폐하는 것을 특징으로 하는 전도성 양면 점착테이프"를 개시하고 있다. Therefore, prevention measures against electromagnetic interference generated from electronic devices and the like have become increasingly important. These electromagnetic waves are generated by the electronic device itself or invade the electronic device from the outside, and also electromagnetic waves flow along the connected circuit lines, which may cause various damages and interference. Conductive tapes have been proposed and used in various ways to block electromagnetic waves, and these conductive tapes have a problem due to unrolling or burr of the material. For example, Korean Patent Application No. 2008-0039964 relates to an ultra-thin conductive tape for electromagnetic wave shielding, and a method for manufacturing the same, which is "physical by sputter etching and plasma etching or corona discharge etching after vacuum and cleaning using a low temperature plasma apparatus. An ultra-thin insulating film for electromagnetic wave shielding, in which an electroconductive substrate coated with a conductive adhesive on one or both surfaces is laminated after a metal having excellent electrical conductivity is plated with an interfacial treatment, and an ultra-thin insulating film having holes perforated at regular intervals. A substrate layer; the ultra-thin film bordering the perforated holes At least one plating layer surrounding the insulating film base layer, wherein the metal having excellent electrical conductivity is plated by electrolytic, electroless, substitution, vacuum deposition, or sputtering; and a conductive adhesive layer attached to one or both surfaces thereof. To ultra-thin conductive tape for electromagnetic wave shielding. As another example, the Republic of Korea Utility Model Registration No. 2005-0021299 is a conductive double-sided adhesive tape "In the tape, the sheet layer as a base material, the first conductive metal paste coating layer coated on the upper side of the sheet, and the lower side of the sheet A second conductive metal paste coating layer coated on the first conductive layer, a first conductive adhesive layer laminated on the first conductive metal paste coating layer, a second conductive adhesive layer laminated on the second conductive metal paste coating layer, and the second conductive metal paste Conductive double-sided adhesive tape consisting of a release paper layer laminated on the other side of the second conductive adhesive layer laminated on the coating layer, conducting electricity and shielding electromagnetic waves by applying electricity to the upper and lower surfaces when adhered to a specific part of the specific device and apparatus ".

그러나, 상기한 종래의 기술들은 각각 이들 기술이 해결하고자하는 이전 기술의 문제점을 해결하면서 전자기파 차단효과를 나타내는 작용효과는 있으나, 그 제조 공정이 복잡하여 제조원가가 상승하고, 또한 종래의 일반적인 전자파 차폐용 전도성 섬유 양면 테이프의 경우에는 경시 변화에 따라서 전도성 점착제가 상층부에서 하층부로 전사되는 일이 발생하여 전자파 차폐성능 및 수명을 저하시키는 문제점이 있다.
However, each of the above-mentioned conventional techniques has an effect of exhibiting electromagnetic wave blocking effect while solving the problems of the prior arts to be solved by these techniques, but the manufacturing process is complicated and the manufacturing cost increases, and the conventional general electromagnetic shielding In the case of the conductive fiber double-sided tape, there is a problem in that the conductive adhesive is transferred from the upper layer to the lower layer according to the change over time, thereby reducing the electromagnetic shielding performance and lifespan.
