Abstract
An electrically conductive nano-class (less than 178 nm) microparticle containing Sb for the fluorescent screen of CRT is prepared from tin chloride, antimony chloride, zirconium oxide, titanium oxide, silicon oxide, coupling agent, alcohol and aque pure as raw materials through high-temp. and high-pressure hydrothermal synthesizing reaction to complete the process of dechlorination and oxidation, and further through dispersing, classifying, and concentrating. It can improve the definition of display device.
Description
The invention belongs to the nanometer technology application.
Electrically conducting nano-class Sb-contained microparticles is a kind of nanosize metal oxide powder, Main Ingredients and Appearance is a tin, antimony, zirconium, titanium, the oxide of silicon, crystallite dimension is below 100nm, behind the silicon dioxide parcel, form the compound single-size of granularity less than 178nm, anti-dazzle liquid of making after being scattered in alcohol or the water or conductive particle liquid, be applied in display tube, on the viewing screen glass bulb, play anti-dazzle, antistatic, radiation-resistant effect, thereby improve the definition of display image greatly, alleviate display device to human body or the static and the radiation hazradial bundle of electric device on every side, this product also can be applicable to touch-screen and far infrared reflecting glass etc.
Have six big critical materials in the production of display tube, picture tube, glass bulb, shadow mask, electron gun, deflecting coil, electrically-conducting paint, anti-dazzle conductive particle material.Wherein preceding 4 kinds of materials all domesticize, and the 5th kind of material has only the some projects production domesticization, and anti-dazzle conductive particle liquid is still blank out, and domestic all demand producers are all by import.
The purpose of this invention is to provide a kind of be used to improve picture tube, display tube definition, anti-dazzle, antistatic, radiation-resistant electrically conducting nano-class Sb-contained microparticles and preparation method thereof.
