Description
본 발명은 컬러브라운관(Cathode Ray Tube : CRT)의 필르밍막 형성에 사용되는 필르밍액에 관한 것으로, 특히 부틸 메타크릴레이트(Butyl methacrylate)를 70 wt％ 이상 함유하는 아크릴 에멀젼을 사용하여 추가의 소성 공정이 필요 없고, 안전하고 간단하게 공정을 수행할 수 있는 필르밍액에 관한 것이다.The present invention relates to a peeling liquid used for forming a film of a color brown tube (Cathode Ray Tube: CRT), in particular an additional baking process using an acrylic emulsion containing at least 70 wt% of butyl methacrylate. There is no need for this, and it is related with the blooming liquid which can carry out a process safely and simply.
일반적으로 칼라 음극선관의 형광막은 전자총에서 방출되는 전자빔 에너지를 광 에너지로 변환시키는 곳으로, 형광체의 여기 발광에 의해서 화상을 구현하며, 블랙 매트릭스 성형공정과 녹색, 청색, 적색 형광패턴 형성공정을 통하여 만들어진다.In general, a fluorescent film of a color cathode ray tube converts electron beam energy emitted from an electron gun into light energy, and realizes an image by excitation emission of a phosphor, and a black matrix forming process and a green, blue and red fluorescent pattern forming process. Is made.
이와 같이 형성된 형광막은 형광막의 휘도를 향상시키고, 형광막의 전위강하를 방지하고, 이온 충격에 의한 형광면이 타는 것을 방지하기 위하여 진공상태에서 알루미늄을 증발 확산시켜 얇은 알루미늄막을 만들어 주게 된다.The fluorescent film thus formed improves the luminance of the fluorescent film, prevents the potential drop of the fluorescent film, and prevents burning of the fluorescent surface due to ion bombardment, thereby evaporating and diffusing aluminum under vacuum to form a thin aluminum film.
그러나, 적(赤), 녹(綠), 청(靑) 형광체 스트라이프가 형성된 형광막은 스트라이프 내의 형광체 구멍뚫림으로 인하여 평편한 면을 만들어 주지 못하기 때문에 여기에 직접 알루미늄울 증착시키게 되면 알루미늄이 형광체를 뚫고 들어가 알루미늄막의 거울로서의 효과를 감소시키게 된다.However, since the phosphor film with red, green, and blue phosphor stripes does not form a flat surface due to phosphor holes in the stripe, if aluminum wool is deposited directly on the aluminum, the phosphors It penetrates and reduces the effect of the aluminum film as a mirror.
따라서 일반적으로 칼라 음극선관에 있어서는 이러한 현상을 방지하기 위하여, 형광체 사이의 구멍을 막기 위한 특수한 도포 물질을 형광막 위에 도포하게 된다. 즉, 형광체 층을 패널 내면에 도포한 후, 필르밍액을 도포하여 중간막을 형성하므로써 알루미늄 증착을 매끄럽게 하고, 형광체 사이의 구멍에 의한 알루미늄막의 요철 현상을 완화하여 알루미늄막의 반사효율을 높여 휘도를 향상시킬 수 있게 하는 것이다.Therefore, in general, in the color cathode ray tube, in order to prevent such a phenomenon, a special coating material for blocking the holes between the phosphors is coated on the phosphor film. That is, after the phosphor layer is applied to the inner surface of the panel, a film is applied to form an intermediate film to smooth the deposition of aluminum, to reduce the unevenness of the aluminum film caused by the holes between the phosphors, and to increase the reflection efficiency of the aluminum film to improve luminance. To make it possible.
이와 같은 중간막은 형광체에 나쁜 영향을 미치지 않고 전자총의 전자 방출을 방해하지 않는 물질로 하지 않으면 안되므로 열분해 가능한 유기 피막으로 형성되며, 이 유기 피막을 형성하는 공정을 필르밍이라 한다.Since such an interlayer film must be made of a material that does not adversely affect the phosphor and does not interfere with electron emission of the electron gun, it is formed into a thermally decomposable organic film, and the process of forming the organic film is called filming.
또한, 이러한 필르밍으로 형성된 유기 피막 위에 알루미늄을 진공 증착하고 그후 불필요한 유기물을 완전히 소산하기 위하여는 소성공정을 하여야 하며, 이 소성공정에서는 알루미늄이 부착된 형광면을 350- 450 ℃로 가열한다.In addition, in order to vacuum-deposit aluminum on the organic film formed by this filming and then completely dissipate unnecessary organic substances, a firing process must be performed. In this firing process, the aluminum-attached fluorescent surface is heated to 350-450 ° C.
이와 같은 필르밍막을 형성하는 종래의 기술은 크게 수계 아크릴 에멀젼을 사용하는 것과 유성계인 락카를 사용하는 2 가지 방법으로 대별된다.Conventional techniques for forming such filming films are roughly divided into two methods using aqueous acrylic emulsions and oil based lacquers.
그러나, 종래의 수계 아크릴 에멀젼을 사용하는 방법에서는 폴리비닐알콜 (Poly vinyl alcohol), 아크릴 에멀젼, 글리세린, 수산화암모늄, 과산화수소수 등을 첨가하여 사용하고 있으나, 이 경우 알루미늄막 형성이 끝난 후, 형광막과 필르밍막의 유기물을 분해하기 위하여 400- 450 ℃의 온도 범위에서 소성을 하지만, 이후 패널(panel)과 펀널(funnel)의 결합을 위하여 다시 400- 450 ℃의 온도 범위에서 프릿트 실링하는 공정이 있기 때문에 결국 막은 이중 소성 처리되는 불리점이 있다. 한편 별도의 소성 공정이 없을 경우에는 필르밍막 유기물의 분해가 늦기 때문에 프릿트의 연화점과 결정화 온도인 400- 450 ℃ 에서도 유기물 분해 가스가 잔존하여 프릿트의 실링을 방해하는 문제점이 있다.However, in the conventional method of using an aqueous acrylic emulsion, a polyvinyl alcohol, an acrylic emulsion, glycerin, ammonium hydroxide, hydrogen peroxide, etc. is added and used, but in this case, after the aluminum film is formed, the fluorescent film is used. In order to decompose the organic material of the film and the film, the firing is performed at a temperature range of 400 to 450 ° C., but the frit sealing process is then performed again at a temperature range of 400 to 450 ° C. for the combination of a panel and a funnel. As a result, the film has the disadvantage of being subjected to double firing. On the other hand, if there is no separate firing process, since decomposition of the filming film organic matter is late, organic decomposition gas remains at the softening point of the frit and the crystallization temperature of 400-450 ° C., thus preventing the frit sealing.
