Description
Technical field
The invention belongs to the luminescent material applied technical field, relate to a kind of plasma display (PDP) phosphor material powder performance and develop skill.
Background technology
The color plasma flat-panel display device is big with its display area, clear display, parallax is little, body thin can wall hanging etc. many advantages, become one of important developing direction of field of information display.Existing more family expenses color plasma television is sold in market in China.But most key part of color plasma television and material all are to rely on abroad.Fluorescent material is one of critical material of plasma display manufacturing, and the brightness of the color plasma fluorescent material of color plasma fluorescent material research institute of a few at home family development has reached external index, but overall performance still has gap.The phosphor surface performance is exactly one of gap.
Summary of the invention
The purpose of this invention is to provide a kind of fluorescent material that is more suitable for being used on the PDP indicating meter, make its performance be more suitable for the requirement of plasma display to fluorescent material, reach after the processing plasma display with fluorescent material seldom to the luminosity influence, but fluorescent material settling property in the later synthetic plasma panel display fluorescent powder paste material is had bigger improvement.
Its constituent of coated fertilizer of the present invention contains following material: two kinds of amphotericses and Wax, two or more tensio-active agents are used, be to adjust according to their different HLB values to realize cooperating, the add-on of the tensio-active agent that the HLB value is lower is 0.1～10% of a Wax weight, HLB value higher surface activity agent add-on is 0.001～2% of a fluorescent material weight, has wrapped up tensio-active agent and Wax at phosphor surface.Above-mentioned Wax is selected whiteruss or synthetic paraffin or micro mist wax or polyethylene wax or oxidized polyethlene wax or chlorinatedpolyethylene wax.The tensio-active agent of above-mentioned tensio-active agent selection department's Pan S series or tween T series or polyoxyethylene nonylphenol ether NP series or alkylphenol polyoxyethylene OP series.
Plasma display of the present invention is with the preparation method of fluorescent material coating: at first wrapped up the agent of HLB value higher surface activity at phosphor surface; Wrap up lower tensio-active agent of HLB value and Wax again.
Technological process of the present invention is:
A dissolves in the HLB value higher surface activity agent that weighs up weight in the water of weight in proportion, the formation surfactant soln; The add-on of tensio-active agent is 0.001～2% of a fluorescent material weight, and it is that oil-absorption(number) with fluorescent material changes that the add-on of tensio-active agent changes;
B adds the fluorescent material that weighs up weight in surfactant soln, heating is also stirred fully, makes the agent of HLB value higher surface activity be wrapped in phosphor surface equably, makes coated fluorescent material;
C is the coated fluorescent material of step b precipitation, dries after pouring out the water on upper strata, promptly obtains having the first coated fluorescent material of surface active layer;
D mixes the lower tensio-active agent of HLB value that weighs up weight in proportion with Wax, and heat 60～80 ℃, and stir fully, form active Wax material, the add-on of tensio-active agent normally Wax weight 0.1～10%;
E will have in the first coated fluorescent material of surface active layer and the steps d active Wax material mixing together among the step c, and stirs fully, then finishes the preparation of plasma display with the fluorescent material coating.
The present invention handles plasma display fluorescent material with surfactant material, make its performance be more suitable for the requirement of plasma display to fluorescent material, reach after the processing plasma display with fluorescent material seldom to the luminosity influence, but fluorescent material settling property in the later synthetic plasma panel display fluorescent powder paste material there is bigger improvement, and technological process is simple, easy handling, suitable batch production.
