Abstract

본 발명은 음극선관의 도전성 피막액에 관한 것으로 특히 스폰지 롤러를 이용하여 외부도전막을 형성시키는 도전막 자동화 작업에 적당하도록 그 성분비율과 입자크기를 조성하여 작업성을 향상시키고 음극선관의 품질을 높이고자 한 것이다.The present invention relates to a conductive coating liquid of a cathode ray tube, in particular, by forming a composition ratio and particle size to be suitable for the automated operation of the conductive film forming an outer conductive layer using a sponge roller to improve the workability and improve the quality of the cathode ray tube I did it.

종래의 기술은 피막액을 스폰지 롤러를 이용한 자동화 도포작업에 사용하는 경우 스폰지 롤러의 기공 때문에 거품이 많이 생겨 도포면에 보기흉한 얼룩과 요철이 발생하며, 또 거품이 없을 경우 작은 흑연입자가 도포면을 따라 흘러내려서 얼룩이 발생하므로 음극선관이 균일한 저항값을 갖지 못하게 되는 문제점이 있었다.In the conventional technique, when the coating liquid is used for an automatic coating operation using a sponge roller, bubbles are generated due to the pores of the sponge roller, causing unsightly stains and irregularities on the coated surface. There is a problem that the cathode ray tube does not have a uniform resistance value because the stain flows.

따라서 본 발명은 음극선관의 외부도전막 형성을 위한 도전성 피막액의 조성물질의 입자크기와 성분비율을 변화시켜 스폰지 롤러를 이용하여 도포할 수 있도록 하는 음극선관의 도전성 피막액을 제공한 것이다.Accordingly, the present invention provides a conductive coating liquid of a cathode ray tube which can be coated using a sponge roller by changing the particle size and composition ratio of the composition of the conductive coating liquid for forming an outer conductive film of the cathode ray tube.
