Description of the invention (I) Background of the invention (a) Field of the invention The present invention relates to a method for manufacturing a phosphor material for a cathode ray tube (CRT) phosphor layer. In particular, it is a method for manufacturing pigments coated with fluorescent materials with high brightness and good color purity. (b) Relevant antagonistic instructions. The labor powder material emits visible light when receiving electron beam or ultraviolet rays. The phosphor material used in the cathode ray tube includes a host material 'that absorbs energy from an electron beam or ultraviolet rays, and an activator that radiates visible light when receiving energy from the host material. The main materials are usually compounds such as oxides' sulfides, selenides, and fluorides, as well as calcium, barium, beryllium, magnesium, zinc, and cadmium silicates, phosphates, arsenates, and tungstates. The activator usually uses manganese, magnesium, copper, bismuth, antimony, lead, titanium, and various rare earth elements. The phosphor material is generated by mixing the main material and the activator and burning. Then the burned material is cleaned and ball milled, and the pigment is coated on the ball milled material to increase the color purity of the material and the quality of the CRT panel. Adhesion. The pigment reduces some unwanted light, and greatly enhances the contrast of the reproduced image by absorbing external light reflected on the panel surface. The pigment-coated material is washed, dried, and screened to produce the final phosphor material. β In Japanese Laid-Open Patent No. 50-56416, a composition containing a pigment and gum arabic is added to the gel-coated phosphor material so as to coat the gel-coated phosphor material. Pigment, so the gel's positive charge is electrostatic. 2 The paper size applies the Chinese National Standard (CNS) Λ4 specification (210X297 cm) II 1 Order ^ (read the precautions before reading the back page of this page) η η.

Description of the Invention (2) Attracting negative charges on gum arabic. The pigment-coated phosphor material is then thermoset at 110 ° C for 20 hours, or a hardener is added at 5 ° C or below to condense. However, in the conventional method t, the pigment may be peeled off or separated from the phosphor material, and thus the color purity may be deteriorated. In addition, the pigment may agglomerate during the mixing of the pigment and gum arabic, so the pigment cannot be evenly coated on the phosphor material 'to reduce the brightness of the phosphor material. These disadvantages cause more serious problems when phosphor materials are used in high-resolution and high-contrast CRTs. Summary of the Invention It is an object of the present invention to provide a method for making a phosphor material to prevent the pigment from falling off from the bare phosphor material, thereby producing a phosphor material with high color purity. Another object of the present invention is to provide a method for manufacturing a phosphor material, so as to prevent the pigment from agglomerating when it is attached to the bare phosphor material, so that the pigment can be uniformly coated on the bare phosphor material and increase the brightness of the phosphor material. In order to achieve such and other purposes, the method for manufacturing a phosphor material includes the steps of: mixing a bare phosphor material with water, and adding an adhesive to the mixture of the bare phosphor material and water to produce an adherent A fluorescent solution of the agent 'and a first surfactant is added to the fluorescent solution of the adhesive. Next, a pigment dispersion solution containing a second surfactant and a pigment is added to the phosphor solution to which the binder is attached to produce a pigment-coated phosphor. The final pigment-coated phosphor is washed and dry.
