Abstract
An anti-reflection coating composite and a method using the composite to manufacture colored cathode-ray tube are disclosed. The preparation of the coating composite is that: the mixed silicate is added into the solution containing alcohol solvent or polar solvent, acid catalyst and water, and then conducts hydration and condensation polymerization. The method comprises the following steps: the panel outer surface is coated with conductive solution to form a conductive film; the conductive film is coated with the coating composite to form a protection film of the conductive film; the conductive film and the protection film are simultaneously baked to form a single layer. In accordance with the invention, the reflection phenomenon of surrounding lights is decreased, and the contrast ratio and working capacity of the cathode-ray tube are improved.
Description
The present invention relates to a kind of coating non-glare coating compostion on the colour cathode ray tube front surface and make the method for color cathode ray tube, the antistatic property of wherein said synthetics increases, not dazzling under the ambient light effect, and adhesive capacity increases.
The glass of normally transparent degree excellence or plastics are widely used as the material of display device such as cathode tube, chromoscope and liquid-crystal display.But glass or plastics itself are insulating material, thereby the easy static electricity gathered lotus of the display surface of cathode tube.This static charge inhales dust to display surface, the brightness and contrast of cathode tube is degenerated, and reduce its sharpness.If the outside surface that uses the people of device to touch cathode tube in addition also can be shocked by electricity.In addition, the front panel that this class material is made, its outside surface contains glossy material, thereby the light around the strong reflection.Like this, TV will watch the image that is presented on the panel inner surface to have any problem to the crowd.
For addressing these problems, various scattering of light around making has been proposed so far to reduce the method for catoptrical brightness and sharpness.
For example, it is with the glass surface of the hydrogen fluoride local corrosion face-plate of a cathode-ray tube that a kind of chemical method is arranged, and forms slight unfairness thereon.But this method tends to cause pollution problem, and damages panel, and has the not problem of reproducible when processing is bad.Forming irregular sand-blast with abrasive material at panel surface has such problem, i.e. quality instability, and replicability is poor, can mix the foreign matter that resembles abrasive material etc.The lining method that plastics film is overlayed on the panel tends to injure panel surface, but also can the elution organic solvent.
For addressing the above problem, the someone has adopted non-glare coating compostion has been coated to coating method on the panel.
For example Japanese Utility Model 50-26277 communique was just introduced with the method with slight irregular film lining cathode tube.To have the silicon compound of 4 functional groups and alcohols or ester class and be mixed into mixture, this mixture be sprayed on the surface of this face-plate of a cathode-ray tube.According to described method, can obtain the surface of good layer, but ridity is bad, and overlay often flows after the spraying, formed roughness is poor.
Japanese patent gazette 61-118932 has introduced a kind of cathode tube with antistatic property.In this cathode tube, Si (OR) is gone up in the spraying of face-plate of a cathode-ray tube surface
4(wherein R is an alkyl) cures under 80 ℃ to 150 ℃ temperature then, thus make the Si-O-Si siloxane structure some silanol groups (=Si-OH) stay, thereby make described panel surface have antistatic property.The upper layer that so draws, the intensity height, but can reduce with heating condition.Can not obtain anlistatig effect in addition.
Disclose at SiO among the Japanese patent gazette 61-118946
2Film surface forms the upper layer of siliceous alcohol radical, forms the method for conductive surface layer thus.But this method is similar with Japanese patent gazette 61-118932 basically, and has the problem that antistatic effect descends in time.
In addition, United States Patent (USP) 4,563 has been introduced a kind of cathode tube with the anti-dazzle coating of antistatic silicon ester in 612.
The surface irregularity of coating, this makes it have not dazzling performance.Employing be selected from by a following group element (Pt, Pd, Sn and Au) wherein the metallic compound of at least a element improve under the situation of electric conductivity of silicon ester material conductive layer weakness, and be easy to damage.
Here, in order to prevent this damage, cathode tube is that the antistatic layer of being made by silicon ester material and inorganic metal compound with bilayer structure is produced, but this cathode tube high price, the manufacturing process complexity, and a little less than the adhesive power between silicon ester material and the inorganic metal compound layer.
Therefore the purpose of this invention is to provide a kind of manufacture method of cathode tube, be formed with the anti-dazzle antistatic film that adhesive power increases on the outside surface of this face-plate of a cathode-ray tube.
