MANUFACTURING METHOD OF CATHODE RAY TUBE

摘要

The cathode ray tube is mfd. by coating an electroconductive mixture composed of copolymerization of 20-60 wt. pts. of the rubber latex of 70-85% gel Si alkoxide, solvent, electroconductive metal (Sn,Sb,In and/or Pd) and acid (HCl or HNO3) on the outer surface of the panel, drying the coated outer surface at 100 deg.C or less for 10-120 min to form an electroconductive film, coating the mixture free of the electroconductive metal on the film to form a protective film, and fireing the films at 100-200 deg.C for 10-120 min. The CRT has an improved surface- and adhesion- strength.
