Abstract
The invention belongs to luminescent material applied technique field. And it relates to plasma phosphor paste and its synthetic method. The paste is made up of high volatilization point solvent, plasma phosphor, more than two medium materials, and polysiloxanes. The synthetic method includes the following steps: adding the medium material into the high volatilization point solvent; then adding into polysiloxanes to form medium glue liquor; mixing PDP phosphor with the medium glue liquor; and grinding. The formed material has the advantages of simple technological process, and easy operation. And it is adapted for mass production.
Description
Technical field
The invention belongs to the luminescent material applied technical field, relate to a kind of plasma body fluorescent powder paste material and synthetic.
Background technology
Current, in flat pannel display market, the world, the color plasma flat-panel display device has become one of important developing direction of field of information display with the advantage of its uniqueness.Recent years, the market of color plasma flat-panel monitor rapidly enlarges, and color plasma television has now begun to step into family in China.And the color plasma fluorescent powder paste material is one of critical material of plasma display manufacturing, and China still can not produce now.What the production of domestic several families color plasma flat-panel display device and research institute used is the import slurry of high price, has had a strong impact on the development of China PDP technique of display.
At present, domestic fluorescent powder paste material is solid fluorescence powder particulate is dispersed in the organic medium glue and makes.Common medium glue mainly be made up of organic solvent and the ethyl cellulose cellulosic material that can be used as binding agent.The shortcoming of existing method is a solvent and generally comparatively simple as the material of binding agent, thereby the performance of fluorescent powder paste material can not adapt to the needs of color plasma flat-panel display device fully, it is much lower to exist the brightness of PDP light-emitting phosphor to fall, prolonged preservation unstable properties problem.
Summary of the invention
For a kind of organic resin of employing that solves in the above-mentioned background technology is made caking agent making slurry, cause light-emitting phosphor brightness to reduce more problem easily, the purpose of this invention is to provide a kind of fluorescent powder paste material and synthetic method thereof that light-emitting phosphor brightness reduction is less, be suitable for being used in plasma flat demonstration (PDP) that make.
The constituent of slurry contains: high volatilization point solvent, plasma body fluorescent material, the two or more dielectric material and the polysiloxane that can form glue, the weight ratio of slurry is 100%, the two or more dielectric material add-ons that can form glue are 8～15% of slurry weight ratio, and its add-on of polysiloxane is 3～12% of a slurry weight ratio.
The synthetic method of slurry is characterized in that: its synthetic technological process is:
A, the two or more glue dielectric materials that weigh up weight are dissolved in respectively in the high volatilization point solvent that weighs up weight, form two or more glues respectively;
B, the two or more glues of step a are mixed, and stir, obtain the blending agent glue;
Add polysiloxane in c, the blending agent glue, and stir, obtain the medium glue step b;
D, the medium glue of PDP fluorescent material and step c mixed stir, obtain elementary slurry;
E, the elementary slurry of steps d ground with three-roll grinder after, then finish the making of fluorescent powder paste material for plasma plate display.
Two or more glue dielectric materials are dissolved in the high volatilization point solvent that adapts with it, obtain two or more glues, then two or more glues are mixed in proportion, its blended ratio changes to some extent with different PDP fluorescent material.
