Abstract

The present invention relates to a black substrate paint manufacturing technique of high-purity ultrafine graphite fine particles. 350kg of high-purity ultrafine graphite fine particle, 604kg of deionized water, 6kg of sodium lignosulphonate and 40kg of ammonia are taken out, added in a 1300 L preparation tank according to sequence, mixed and dispersed for 75 minutes by a dispersion machine with rotational speed of 1000rmp; 70kg of aluminum sol and 7kg of polyacrylamide are added in the preparation tank, mixed and dispersed for 150 minutes by the dispersion machine with rotational speed of 1000rmp; the mixed and dispersed materials are filtered by a filter screen of 100, packed with 20L plastic barrels, sealed and warehoused. The present invention has following advantages of improving picture definition and brightness of a color picture tube, simplifying manufacturing technique and reducing production cost.
