Description
Technical field
The present invention relates to a kind of colorize method of cathode-ray luminescence material, be specifically related to a kind of colorize method of blue cathode-ray luminescence material.
Background technology
ZnS:Ag (Cl) is as the tricolour picture tube blue emitting material, and application has reached more than 30 year; Its luminous efficiency height, the high praise that chemical stability is good, colour purity that sunset glow is suitable and good obtains people.
As everyone knows; ZnS:Ag (Cl) is as blue colour fluorescent powder; for a long time; through regular meeting colour mixture problem (i.e. residual blue powder on green vermicelli appears in use; or on the blue powder bar residual rouge and powder); so that picture tube exists look to pollute, and is insider's question of common concern so take a kind of coloring process thoroughly to eliminate colour mixture always.
Summary of the invention
The purpose of this invention is to provide a kind of colorize method that can thoroughly eliminate the blue cathode-ray luminescence material of mixed color phenomenon.
For achieving the above object, the technical solution used in the present invention is: at first with ZnS, AgNO
3, flux and sulphur mixes, mix and add by mass percentage the flux of ZnS quality 1.0-2.0%, the activator AgNO of 130ppm-180ppm take ZnS as matrix
3With 2% sulphur, said flux is: AlCl
3, Al
2(SO

3: NaCl=868: 378: 154, the oxide of after 890 ℃ of-960 ℃ of lower calcination 60-90 minutes, removing top after mixing and deionized water mix by 1: 3 mass ratio and 100-300 purpose screen cloth get powder and starch, the quality of pressing then the powder slurry stirs the KP1 that adds 12～20ml/kg in the powder slurry, the quality that starch by powder after 30 minutes at the interval again adds 120～200ml/kg concentration in the powder slurry be the ZnSO of 0.4mol/L
4, stirred the sedimentation draining 30 minutes, and wash, after the dehydration, powder agglomates is put into ball mill, and take powder agglomates: glass marble: deionized water adds glass marble and deionized water as 1: 1: 0.5 mass ratio, the quality of pressing simultaneously powder agglomates adds the silicate dispersant of 3.0ml/kg, ball milling 12～16 hours is emitted the powder slurry, water elutration then, after the standing and drying, cross 300～500 mesh sieves and get the cathode-ray luminescence material former powder of blue powder; Then the former powder of blue powder and water are mixed by 1: 2 mass ratio and obtain the powder slurry, the cobalt blue dye that adds successively again 10g～45g/kg by the quality of powder slurry, 1.0 the Acrylic Resin Emulsion of～8.0g/kg, be 2.0-4.5 with the sulphur acid for adjusting pH value, dehydrate, cross behind 300 mesh sieves with water by 1: 2 mass ratio mix the powder slurry, the quality by the powder slurry adds the gelatin of 0～2g/kg, the Arabic gum of 0.2g～2g/kg, the SiO of 1g～4g/kg successively again
2And the concentration of 10ml～40ml/kg is the ZnSO of 0.4mol/kg
4, transfer pH to 8.3～8.7 with ammoniacal liquor, dehydration and sieved after under 100～150 ℃ dry 12～24 hours 300 orders, 500 orders or 600 mesh sieves get final product.
The present invention adds ZnSO add KP1 in burning the finished powder slurry after again
4, stir, the sedimentation draining, i.e. former powder zinc silicate surface treatment and twice are painted namely use earlier the painted drying and screening of latex after, re-use gelatin and Arabic gum secondary coloring and Zn (OH)
2Be painted rear adding ZnSO
4, and to transfer with ammoniacal liquor be Zn (OH)
2Surface treatment, thus thoroughly eliminate blue powder in use at green powder, blue powder on the graphite and residual on blue powder of rouge and powder.
