Description of the invention (f) Background and prior art The present invention is generally related to color television image tubes, and is particularly a modification. Good contact column coating composition and method To provide an electrical path between the color image tube shadow mask and the screen panel. The color television cathode-ray image tube includes a glass tube, which is composed of a funnel and a panel, and the panel is sealed at the flashing end of the funnel. The electron gun is mounted on the neck of the funnel to provide one or more electron beams. The inner surface of the panel is almost flat, and phosphorus groups are deposited on it, which can be excited by the electron beam. The shadow mask provides a choice of colors by masking the phosphorus group, so the phosphorus group is excited by only one of the electron beams. The shadow mask is attached to the panel in a precise position by a plurality of suspension springs, and the metal contact posts extending from the suspension spring and the panel are detachably connected. A conductive coating of colloidal graphite is applied to the inner surface of the funnel and a high voltage is applied via an anode button in the funnel wall. It is customary to apply an electron-permeable aluminum film on the phosphor screen to aluminize the phosphor screen. This film acts like a mirror, and can increase the brightness of the display by reflecting backwardly directed light generated by phosphorous. A film of an organic material, such as a paint, can be applied to the phosphorus deposits before applying aluminum. This organic film fills the uneven areas of the phosphorous deposits and provides a smooth surface for aluminum film deposition, which takes advantage of the smoothness of paint. Basically, the anode voltage on the funnel coating is applied to the shadow mask and aluminum film. The electrical path to this end consists of one or more springs that extend from the shadow mask and interface with the funnel coating. The anode potential of the shadow mask passes through the shadow mask suspension spring and the metal support contact column __________ 3 The paper wave scale is applicable to the Chinese National Standard (CNS) Λ4 specification (210X 297 mm) yl ----- 赛 I — _. ...

Description of the invention (>) and communicate with the aluminum film. After completing the electrical path of the aluminum film, the metal supporting contact post is coated with a layer of conductive "moustache", which extends to the brocade film. The material containing conductive whiskers is usually called a contact post coating. Previously widely used The conductive material used as the coating of the contact post includes a water-soluble silicate that can be applied with a brush. The water is removed during the subsequent image tube baking process, and the contact post and the aluminum film A hard conductive film is left between them. Such water-based solutions often contain potassium silicate or sodium silicate as a binder, and usually do not "wet" properly or stick to the component. As a result, Fragments of coatings often come from contact columns and The glass area peels off and blocks one or more apertures in the shadow mask, resulting in an unacceptable image tube. Such particles may also cause arcing between the electrodes and / or cathode damage in the electron gun area. Water-soluble coating The coating requires an additional baking cycle after aluminizing and before the contact post coating is applied. The inventors in U.S. Patent Nos. 4,289,800 and 4,301,041 and their authorized Zenith Electronics Corporation solve the problems of the conventional techniques described above. And by eliminating the additional baking step after aluminizing, significant cost savings are introduced into the manufacturing process. These patents are listed here as references, which disclose a method and contact post coating composition that includes The paint film (under the aluminum film) is used as a mixture of glass frit particles and colloidal graphite in a vaporizable solvent, and a thickener to provide coatable viscosity. In Lehr During the baking cycle in the (oven), the solvent will penetrate the paint layer and exit through the porous aluminum film. The methods described in these patents and the contact column coating solution are widely used. It has been used in industry and has performed well in these years. 4 This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm.) .'- \ — / (Please read the precautions in the back first (Fill in this page) ^ °

Description of the invention (3) The employee ’s cooperative of the Central Government Bureau of the Ministry of Economic Affairs printed the contact column coatings of the glass frit type described in the patents discussed above, if the soil is damaged during the manufacturing process Or 'interrupted' shows deficiencies. Especially when the image tube is subjected to a long period of time in the Lehr temperature of the station, for example, it occurs when the production line is stopped. Lead oxide in glass frit will react with carbon in graphite to form carbon dioxide and lead, and destroy the conductivity of the contact pillar coating. In many cases, 'careful attention to the control of the oven temperature when the production line is stopped can prevent this problem from happening, but in a wide range of outages' this problem may still occur. This problem is often compounded by the fact that a sufficient amount of contact column coating may remain intact, leaving the image tube to pass the final inspection and test, although in practice it may be easy to re-arc and cause eventual failure. Although this problem is not serious in terms of quantity, 'but it is a big disaster for color image tubes' and it is a clear loss and inconvenience for consumers', because it may not be in the routine test of color image tubes. Show up. OBJECT OF THE INVENTION The main object of the present invention is to provide an increase in the reliability of a color cathode ray tube. It is another object of the present invention to provide a reduction in cost due to color cathode ray control. It is a further object of the present invention to provide a cathode ray tube with minimal arcing associated with contact column coatings. Description of the preferred embodiment As mentioned above, a color cathode ray tube has a phosphor-loaded image panel, which is successively covered with a paint film and an aluminum film.

Description of the invention (f) Panel A plurality of extended metal contact posts are fixed to the panel. Via the contact post and the contact post coating, an electrical bridge is provided between the shadow mask and the aluminum film to maintain the film at the anode potential. (As is well known, the shadow mask is electrically connected to the anode voltage, and the anode voltage exists on the coating in the funnel. This is by bridging the non-conductive between the color image tube panel and the funnel. This is achieved by a glass frit sealed spring.) The improved hard-baking solution according to the present invention is used to provide electrical bridging or whiskering of the contact column coating, which basically comprises a mixture of graphite particles in the micrometer range. The particles are suspended in a vaporizable solvent for paint films. This suspension includes a thickening agent in an amount sufficient to produce paintable viscosity for coating with a brush. When the solution is applied between the hanging contact post and the aluminum film, the solution penetrates the paint film. When the image tube is baked, the solution hardens and provides a permanent conductive bridge between the mask and the aluminum film. The viscosity of the solution is in the range of 200 ~ 800cp: and preferably about 550cp. After baking, the resistance of the solution may be in the range of 100 to 500 ohms per square area. The conductive contact post coating of the present invention can be mixed into one described below (manufacturing one gallon). The same material supplied by other suppliers can also be used. 225 grams of acrylic resin (Elvacite 2044, source: ICI acrylic) was dissolved in 2025 grams of purified butyl cellosolve (E179 from Fisher Scientific) as the acrylic resin raw material solution. In a suitable container (2000ml beaker), weigh 225 grams of butyl cellosolve β, add 675 grams of N-butyl acetate (B-396 from Fisher Scientific) and 630 grams of resin binder, and stir until solution _ 6 This paper size applies the Chinese National Standard (CNS) Λ4 specification (2) 0X 297 public holidays (please read the precautions on the back before filling this page) -1¾ Γ 410359 A7 __ ^ ___ B7 V.

The preparation of this coating must be performed carefully and in a properly ventilated area. For example, each person should be equipped with rubber gloves, a gas mask, a lab coat, a hair cover and a shoe cover. Because N-butyl acetate and resin binder solutions are flammable, special care must be taken. The contact post coating prepared and used according to the present invention eliminates the problems caused by the contact post coating using a glass frit substrate. The main feature of the new contact coating is its elasticity (after processing), which enhances its peel resistance. In addition, the contact pillar coating of the present invention has a low cost, while still retaining the advantage that the color image tube does not require an additional baking cycle. In the test, the contact pillar coating of the glass frit substrate of the prior art was applied to the contact pillar and the aluminum film, and was subjected to a temperature of 450 degrees Celsius for two hours. The impedance of this coating rose from 300 ohms to 73,000 ohms. And in _7_ this paper size applies the Chinese National Standard (CNS _) ^ 4+ specifications (210X2 () 7mm) — Ordered by the Consumers ’Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, printed A7 B7 410359 V. Description of the invention (L) The new contact pillar coating was tested under the same conditions, and its impedance was maintained at 300 ohms. In the production line for producing color image tubes, the contact column coating of the glass frit substrate of the prior art has a defective quantity of 0.3% due to the contact column arc phenomenon, and the contact column coating of the present invention does not have any contact Defective column arc. What is described above is a novel contact pillar coating composition and method, which solves the problem of conductivity from the contact pillar to the aluminum film in the color image tube.
