Embodiment 1
[0051]
[0052] Put the reactive diluent, polymer dispersant, and defoamer components into the pulping container, and use a high-speed adjustment disperser to stir for 5-120mins at a speed of 300-1000rmp. Then add the fluorescent pigment in the formulated amount, and stir with a high-speed adjustment disperser for 5-120mins, and the rotation speed is 700-4000rmp. Then add the active oligomer in the formulated amount, and grind with a grinder at a speed of 3000-10000 rpm for 1-24 hours until the fineness of the mixture in the pulping vessel is less than 10 μm. Finally, a photoinitiator dissolved with a certain active monomer is added, and a high-speed disperser is used for high-speed stirring to obtain an ultraviolet-curable organic fluorescent coating for a full-color electroluminescent display. After screen-printing the organic fluorescent paint on the light emitting surface of the electroluminescence display screen, a single-tube medium-pressure mercury lamp is used, and ...
