Abstract

본 발명은 텔레비죤과 같은 영상기구에 사용되는 블라운관에 방폭벤드를 고정시키는 도전성(導專性) 점착테이프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductive adhesive tape for fixing an explosion-proof bend to a blown tube used in an imaging apparatus such as television.

종래의 점착테이프는 입도가 큰 동 또는 알미늄의 도전성 입자를 점착제층 1cm²당 1∼3개 정도를 분포시켜 점착테이프 자체는 도전성을 갖지 못하게 하고, 이 도전성 입자들이 브라운관과 방폭벤드를 통전되도록 한 것이 있었으나, 이는 단위면적당 도전성 입자를 고르게 분포시키기에는 작업상 상당한 어려움이 따르게 됨은 물론, 성글게 분포된 입자들이 유리로 된 브라운관의 주연부를 불균일하게 가압하게 되어 브라운관이 손상될 위험이 매우 컸던 것이다.The conventional adhesive tape distributes about 1 to 3 conductive particles of copper or aluminum having a large particle size per 1 cm ² of the adhesive layer so that the adhesive tape itself is not conductive, and the conductive particles are energized through the CRT and explosion-proof bend. However, this is a considerable difficulty in the even distribution of the conductive particles per unit area, as well as the risk of damage to the CRT due to the non-uniform pressing of the glass tube with the sparsely distributed particles.

이에 본 발명은 유리섬유 망포를 기재로 하여 일측면 또는 양측면에 접착제층을 형성한 접착테이프를 제조함에 있어, 유리섬유 망포 표면에 도전성 물질층을 형성시켜 점착테이프 자체가 도전성을 갖게 하므로서, 브라운관의 방폭벤드간의 통전상태를 완벽하게 하여 정전기의 집적을 방지토록 한 것이다.Accordingly, the present invention is to prepare an adhesive tape having an adhesive layer formed on one side or both sides based on the glass fiber mesh cloth, by forming a conductive material layer on the surface of the glass fiber mesh cloth to make the adhesive tape itself conductive, It is to prevent the accumulation of static electricity by perfecting the energization state between the explosion-proof bends.
