본 발명은 텔레비전이나 모니터 등의 브라운관에 금속밴드를 설치하는 방법에 관한 것이다.The present invention relates to a method for installing a metal band in a tube such as a television or a monitor.

브라운관의 설치에 용이성을 부여하고 브라운관의 폭발을 방지하기 위하여 브라운관의 테두리에 금속밴드를 체결하는바, 이와같이 브라운관에 금속밴드를 설치함에 있어서는, 브라운관의 테두리에 점착테이프를 부착하고, 금속밴드를 가열하여 신장시킨 상태에서 이를 점착테이프 위에 씌우면 금속밴드의 열에 의해 용융되는 열용융성접착제로 인하여 금속밴드와 점착테이프가 서로 접착되고 또 금속밴드가 냉각되어 수축되므로서 브라운관의 테두리에 긴착되게 하며 이러한 점착테이크가 금속밴드의 미끄러짐을 방지하고 금속밴드의 조이는 힘이 브라운관에 균등히 전달되게 하며 브라운관의 파손시 유리파편의 비산을 방지하게 하는 기술이 일본국 특허공개소 58-34881호 및 일본국 특허공고소 63-24291(공고일 1998. 5. 20), 한국특허공고 제91-6390 및 한국특허공고 제91-9770호 등으로 공지된 바 있다.In order to provide easy installation of the CRT and prevent explosion of the CRT, a metal band is fastened to the CRT edge. In this way, when a CRT is attached to the CRT, adhesive tape is attached to the CRT edge and the metal band is heated. When the cover is placed on the adhesive tape in the stretched state, the metal band and the adhesive tape are adhered to each other and the metal band is cooled and shrunk due to the heat-melt adhesive melted by the heat of the metal band. Japanese Patent Publication No. 58-34881 and Japanese Patent Publication have a technology that prevents slipping of metal bands and ensures that the clamping force of the metal bands is evenly transmitted to the CRT and to prevent glass fragments from scattering when the CRT breaks. 63-24291 (published May 20, 1998), Korean Patent Publication No. 91-6390, and It has been known as Patent Publication No. 91-9770, etc. The bar.

그런데 위와 같이 브라운관과 금속밴드의 사이에 점착 테이프를 개재시키는 상술한 종래의 기술은 브라운관과 금속밴드사이의 접합 문제만을 고려하였을 뿐이며 그 이외의 기술적 곤란성 즉, 브라운관에 발생하는 정전기의 처리에는 아무런 기여를 하지 못하고 오히려 정전기의 제거에 곤란성만을 가중시키는 결점이 있었다. 즉, 브라운관의 테두리에 금속의 밴드를 체결하게 되면 브라운관에 발생하는 정전기가 금속밴드에 인가되고 그리하면 금속밴드를 접지시키므로서 정전기의 제거가 용이하였었다. 그러나 위와같이 브라운관과 금속밴드사이에 방폭용 점착테이프를 설치하게 되면 이러한 점착테이프가 절연체로서 작용을 하게 되므로 브라운관과 금속밴드사이를 통전시켜야하는 별도의 기술적 문제가 제기되기에 이르른 것이다. 그리하여 위와 같은 점착테이프를 사용하는 경우에 있어서는 브라운관과 금속밴드사이에 별도의 도전체를 설치하지 않으면 아니되는 결점이 있었다. 이에 본 발명은 브라운관과 금속밴드사이에 점착테이프를 개재시키는 종래의 기술에 있어서의 위와같은 결점을 해소할 수 있도록, 점착테이프 자체가 도전성을 갖게 하므로서 브라운관과 금속밴드 사이에 별도의 통전수단을 설치하지 아니하고서도 브라운관과 금속밴드 사이에 도전성을 확보할 수 있게 한 것인바 이와같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.However, the above-described conventional technique of interposing the adhesive tape between the CRT and the metal band only considers the bonding problem between the CRT and the metal band, and contributes to other technical difficulties, namely, the treatment of static electricity generated in the CRT. There was a flaw that only adds difficulty to the removal of static electricity. In other words, when the metal band is fastened to the edge of the CRT, the static electricity generated in the CRT is applied to the metal band, and thus the static electricity is easily removed by grounding the metal band. However, when the pressure-sensitive adhesive tape is installed between the CRT and the metal band as described above, the adhesive tape acts as an insulator, which leads to a separate technical problem of having to conduct electricity between the CRT and the metal band. Thus, in the case of using the above adhesive tape, there was a drawback that a separate conductor must be provided between the CRT and the metal band. Accordingly, the present invention provides a separate conduction means between the CRT and the metal band while making the adhesive tape itself conductive so as to eliminate the above-mentioned drawback in the prior art of interposing the CSA tape between the CRT and the metal band. Without doing so, it is possible to secure conductivity between the CRT and the metal band. The present invention will be described with reference to the accompanying drawings as follows.

브라운관(1)의 테두리에 점착성테이프(2)를 설치하고 그 외측에 금속밴드(3)를 설치하며 점착성테이프(2)는 유리섬유 등으로 된 기재(21)와 열용융형 접착제층(22)과 점착제층(23)으로 구성시킴에 있어서, 기재(21)의 일표면에 열용융형접착제층을 형성시킴에 있어서는 카본블랙과 탄소파우더 등의 도전체를 혼가한 열용융형접착제를 T다이로 압출시키면서 기재(21)에 코팅하며, 열용융형접착제를 코팅한 기재(21)의 이면에 도포하는 점착제층(23)은 카본블랙과 탄소파우더 및 탄소 섬유 등의 도전체를 혼가한 점착제를 도포하여 형성시킨다.The adhesive tape 2 is provided on the edge of the CRT 1, the metal band 3 is provided on the outside thereof, and the adhesive tape 2 is formed of a substrate 21 made of glass fiber or the like and a hot melt adhesive layer 22. And the pressure-sensitive adhesive layer 23, in forming a heat-melt adhesive layer on one surface of the substrate 21, a heat-melt adhesive mixed with a conductor such as carbon black and carbon powder is used as a T die. The pressure-sensitive adhesive layer 23 coated on the base material 21 while being extruded and applied to the back surface of the base material 21 coated with a hot melt adhesive is coated with an adhesive mixed with a conductor such as carbon black, carbon powder, and carbon fiber. To form.

기재(21)는 종래에 있어서와 같이 유리섬유나 면섬유로 된 망포를 사용하되, 망포로된 기재(21)층이 도전성을 차단해서는 아니되므로, 망포로된 기재(21)가 타층과 전기적으로 분리된 절연층으로서 독립적으로 존재해서는 아니된다. 이는 본발명이 해결하고자 하는 기술적문제의 하나이다. 그리하여 본 발명은 기재(21)의 일 측면에 형성시키는 열용융성접착제층(22)에 카본블랙과 탄소파우더를 혼가하므로서 탄소파우더가 도전성을 제공하게 하였다.Substrate 21 is made of glass cloth or cotton fiber as in the prior art, but since the layer of the base material 21 made of mesh cloth does not block conductivity, the base material 21 made of mesh cloth is electrically separated from other layers. It shall not exist independently as an insulating layer. This is one of the technical problems to be solved by the present invention. Thus, the present invention allows the carbon powder to provide conductivity by intermixing the carbon black and the carbon powder in the heat-melt adhesive layer 22 formed on one side of the substrate 21.

기재(21)에 코팅할 접착제는 열용융성수지인 폴리에치렌 100부량에 카본블랙 3~5부량 탄소가루5~20 부량을 혼가하여 형성시킬 수도 있다. 요컨대 열용융성 접착제는 폴리에치렌을 베이스로하고 이에 도전성을 부여하기 위한 도전체를 혼가하기만 하면 족하다. 다만 도전체의 혼가량이 정도를 지나게 되면 접착성이 저하될 염려가 있다.The adhesive to be coated on the substrate 21 may be formed by mixing 3 to 5 parts by weight of carbon black and 5 to 20 parts by weight of carbon black to 100 parts of polyethylene which is a hot melt resin. In short, the heat-melt adhesive may be sufficient as long as it mixes a conductor based on polyethylene and imparts conductivity thereto. However, when the amount of the conductor is exceeded, the adhesiveness may be lowered.

이와 같은 접착제는 금속밴드(3)와 기재(21)를 접착시키는 외에 기재(21)층에 침투하여 기재(21)층을 도전체로 변성시키는 기능을 가지게 된다. 그리하여 본 발명은, 상술한 바와 같은 종래에 있어서의 점착테이프 특히 상술한 일본국의 발명들이나 한국의 특허발명에 있어서와 같이 기재층과 열용융형접착제층이 구분되어지게 형성시키는 것이 아니고, 열용융형 접착제층을 형성시키는 도전성의 열용융형 접착제가 기재층(21) 또한 도전성을 가지게 한다.Such an adhesive has a function of adhering the metal band 3 and the substrate 21 to penetrate the substrate 21 layer and modifying the substrate 21 layer into a conductor. Thus, the present invention does not form the base material layer and the hot melt adhesive layer separately from each other in the conventional adhesive tape as described above, particularly in the above-described inventions of Japan and the invention of Korea. The electroconductive hot melt adhesive for forming the mold adhesive layer causes the base layer 21 to also have conductivity.

열용융형접착제층(22)이 형성된 기재(21)의 타측면에는 점착제층(23)을 형성시킨다. 점착제층(23)은 상기 특허발명 등에 의해 공지된 임의의 점착제에 카본블랙과 탄소섬유 또는 탄소 파우더를 혼가하여 형성시키므로서 점착제층(23)에 도전성을 부여한다.The adhesive layer 23 is formed on the other side of the base material 21 on which the hot melt adhesive layer 22 is formed. The pressure-sensitive adhesive layer 23 imparts conductivity to the pressure-sensitive adhesive layer 23 by forming carbon black and carbon fiber or carbon powder in an arbitrary pressure-sensitive adhesive known by the above patent invention and the like.

점착제층(23)을 구성하는 점착제는 점착제 100부량에 대하여 약 5~15부량의 카본블랙과 5~15부량의 탄소섬유 또는 탄소 파우더를 혼가하여 형성시킨다. 그리고 카본블랙과 탄소섬유 또는 탄소 파우더가 혼가 될 점착제는 그 조성에 특별한 제한을 가질 이유가 없으며, 따라서 임의의 점착제가 두루 사용될 수 있다. 그러나 본 발명에 사용되는 점착제는 천연고무 80부량(중량비)에 대하여 네오프렌고무(Neoprene rubber)20부량, 알리파틱 하이드로카본 레진(Aliphatic hydrocarbon resin)10~70부량, 검 레진(Gum resin)10~30부량, 산화방지제(Antioxident)1~3부량 및 유연제(Process oil) 0~10부량을 혼가하여 형성시키는 것이 바람직하다.The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 23 is formed by mixing about 5-15 parts of carbon black and 5-15 parts of carbon fiber or carbon powder with respect to 100 parts by weight of the pressure-sensitive adhesive. And the pressure-sensitive adhesive to be mixed with carbon black and carbon fiber or carbon powder has no reason to have a special limitation in its composition, and therefore, any pressure-sensitive adhesive may be used throughout. However, the pressure-sensitive adhesive used in the present invention is 20 parts of neoprene rubber (Neoprene rubber), 10 to 70 parts of aliphatic hydrocarbon resin (Gum resin) to 10 to 30 parts of natural rubber (weight ratio) It is preferable to mix and form the amount, antioxidant 1-3 parts and process oil 0-10 parts.

이와같이하여 제조된 점착테이프(2)를 브라운관(1)과 금속밴드(3)사이에 설치하게 되면, 금속밴드를 브라운관의 테두리에 설치하기 위하여 가열된 금속밴드(3)의 열에 의하여 용융된 열용융형접착제층(22)의 접착제와 점착제층(23)의 점착제가, 냉각 수축되는 금속밴드의 수축압력으로 서로 혼합되어 연결되며, 이제는 점착제층(23)과 기재층(21) 및 열용융성접착제층(22)이 카본블랙과 탄소섬유 또는 탄소 파우더에 의하여 도전체로 변성되며, 따라서 브라운관에서 발생되는 정전기가 점착테이프(2)를 통하여 금속밴드(3)에 인가되고, 금속밴드(3)에 인가되는 정전기는 금속밴드(3)를 접지시키므로서 이를 제거할 수 있게 된다.When the pressure-sensitive adhesive tape (2) thus prepared is installed between the CRT (1) and the metal band (3), the hot melt melted by the heat of the heated metal band (3) to install the metal band on the edge of the CRT The adhesive of the adhesive layer 22 and the adhesive of the adhesive layer 23 are mixed and connected to each other by the shrinkage pressure of the metal band to be cooled and shrunk, and now the adhesive layer 23 and the base layer 21 and the heat-melt adhesive The layer 22 is modified into a conductor by carbon black and carbon fiber or carbon powder, so that static electricity generated in the CRT is applied to the metal band 3 through the adhesive tape 2 and applied to the metal band 3. The static electricity can be removed by grounding the metal band (3).

이와같이 본 발명은 브라운관에 금속밴드를 설치함에 있어서, 브라운관과 금속밴드사이에 점착테이프를 개재시켜 금속밴드의 미끄러짐을 방지하고 금속밴드의 조이는 힘이 브라운관에 균등히 전달되게 하며 브라운관의 파손시 유리파편의 비산을 방지하면서도, 별도의 전도체를 설치하지 아니하고 브라운관과 금속밴드사이에 도전성을 부여하여 정전기를 용이하게 제거할 수 있게 되는 효과가 있다.Thus, in the present invention, in the installation of the metal band in the CRT, the adhesive tape is interposed between the CRT and the CRT to prevent slippage of the metal band, so that the tightening force of the metal band is evenly transmitted to the CRT, and the glass fragments are broken when the CRT is broken. While preventing scattering, there is an effect that can easily remove the static electricity by providing conductivity between the CRT and the metal band without installing a separate conductor.
