Abstract
본 발명은 음극선관의 도전성 피막액에 관한 것으로 특히 도전성 피막액의 침전을 방지하고 분산성을 향상시켜서 도전성 피막 도포품질을 향상시키고 수분 흡착에 의한 가스 방출 방지 및 접착 강도를 향상시키도록 하는 것으로서, 전자총에서부터 형광체에까지 전류가 흐르도록 하는 흑연과, 상기 흑연에 의하여 전류가 흐를때 과전류를 낮추도록 하는 금속산화물과, 상기 흑연과 금속산화물을 펀넬 유리면에 강하게 접착시키는 규산염과, 상기 금속산화물을 골고루 분산시켜서 균일한 외관 및 저항값을 갖게 해주며 침전을 방지해 주는 분산제를 일정비율로 배합하여 피막액을 조성하는 것이다.The present invention relates to a conductive coating liquid of a cathode ray tube, in particular, to prevent the precipitation of the conductive coating liquid and to improve dispersibility, thereby improving the coating quality of the conductive coating, preventing gas release by moisture adsorption, and improving adhesive strength. Graphite to allow current to flow from the electron gun to the phosphor, metal oxide to lower the overcurrent when the current flows by the graphite, silicate to strongly adhere the graphite and the metal oxide to the funnel glass surface, and to evenly disperse the metal oxide It has a uniform appearance and resistance value, and the dispersant that prevents precipitation is mixed in a certain ratio to form a coating liquid.
