路の形成方法である。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an explosion-proof tape for cathode ray tubes, and a circuit that uses the explosion-proof tape to perform explosion-proof treatment on cathode ray tubes and remove static electricity generated at the outer edge of cathode ray tubes. The method relates to a method, and more specifically, static electricity accumulated on the surface of a cathode ray tube is heated on an adhesive tape embedded with an inorganic conductive material wrapped around the maximum outer circumference of the cathode ray tube. This is a method for forming a static electricity removal circuit for a cathode ray tube, in which the organic fluid component in the adhesive layer is fluidized by pressure, and the inorganic conductive material comes into contact with or comes close to the band and the surface of the cathode ray tube, thereby exhibiting an explosion-proofing treatment and a conductive effect at the same time.
テレビジ３ンやデイスプレィに使用されるブラウン管は
、映像を形成する目的の為極めて高い電圧をかける必要
があり、ブラウン管の外縁部には静電気が発生、集積し
易かった。The cathode ray tubes used in televisions and displays require extremely high voltages to be applied in order to form images, and static electricity is likely to generate and accumulate on the outer edge of the cathode ray tube.

を乱すことさえあった。In addition, in recent years, with the expansion of the use of televisions, etc., there are more opportunities to not only see things but also touch them directly.
This static electricity often poses a danger to the human body. Furthermore, static electricity may cause disturbances in image quality, and in extreme cases may even disrupt the image.

たアース回路に接地させるのが一般的である。Various methods have been attempted to eliminate static electricity, which presents such disadvantages, but due to structural constraints such as televisions, the static electricity collected by applying graphite or conductive paint to the outer edge of the cathode ray tube has been tried. It is common to ground the i1 air via a tightening band to a ground circuit placed in a cabinet or the like.

要があり、前記静電気を除去する方法は防爆処理とは別
の工程で行わねばならなかった。Tightening bands are used to prevent cathode ray tubes from imploding due to shock, which is in a highly vacuum state. Tightening the bands effectively transmits pressure and directly hits the glass surface, preventing local scratches and other damage. In order to prevent the occurrence of physical defects, it was necessary to attach a highly insulating adhesive tape between the glass and the band, and the method for removing static electricity had to be performed in a separate process from the explosion-proofing process.

あった。Such a method involves, for example, attaching a conductive tape made of copper or aluminum as a base material and containing a fine powder of copper, etc. in the adhesive to the four corners of the cathode ray tube so that the band/glass is in contact with the tape. However, with this method, the effectiveness may vary depending on the method of attachment, or it may peel off and be completely useless, or it may peel off partially or completely and come into contact with circuits inside the cabinet, causing serious damage. At the same time as causing
There were major disadvantages in terms of production, such as the need for careful construction.
本発明は前述の不利を解決する為、鋭意研究の結果到達

のである。The principle of the present invention is the heat and pressure of the tightening band and the adhesive tape (
This is a groundbreaking product that effectively utilizes the functions of explosion-proof tape) and does not require any changes or additions to the current process.

理と同時にブラウン管の静電気除去回路を形成する方法
である。The present invention provides: 1. An explosion-proof tape for cathode ray tubes comprising an adhesive tape having conductive particles having a diameter within a range of 25 μm to 300 μm in the adhesive layer, at least one per 1 cm as a calculated dispersion; 2 At or near the maximum outer diameter of the cathode ray tube, conductive particles having a diameter within the range of 25 μm to 300 μm are dispersed in the adhesive layer at least 1 cm per cm.
At the same time as the explosion-proof reinforcing treatment, the static electricity removal circuit of the cathode ray tube is added. This is a method of forming.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.
締め付はバンドは真空状態のブラウン管の爆縮を防ぐた

マツチラインのような部分的な突起や段差部分では更に
大きな圧力が加わる。To prevent implosion of the cathode ray tube in a vacuum, the band is designed to heat an extremely high-tensile metal band and use its contraction force to generate a high degree of tightening. The way this band is tightened varies depending on the design of the cathode ray tube and the structure of the band, but in terms of numbers, it should be 30 kC97 cm2 or more at the corners (four corners), and 1 to 10 kl/cm at the surrounding flat areas. Also, the mold
Even greater pressure is applied to local protrusions and stepped areas such as match lines.

の粒径がこれに相当する。The adhesive layer that receives the pressure directly from the band is made up of an organic adhesive layer and a base material, and is wrapped around or partially attached to the outer part of the cathode ray tube in the form of an adhesive tape, and then tightened on top of it. A band can be put on. At this time, in this adhesive layer, the organic component adhesive and pressure-sensitive adhesive are melted or softened by the heat of the band and flow in equilibrium with the pressure of the band, thereby exhibiting an adhesive fixing effect. This equilibrium state differs depending on the location, but in the case of substrates such as glass cloth, the thickness corresponding to the diameter of the glass fiber used becomes rate-limiting at corners where particularly strong pressure is applied; This corresponds to the particle size of the filler and anti-slip component contained in the agent.
本発明はこの現象を利用して粘着層中に無機導電性材料

るものである。The present invention takes advantage of this phenomenon and embeds an inorganic conductive material in the adhesive layer, and uses the heat and pressure of the band to change the resistance value between the glass and the band to the resistance value necessary to remove static electricity, that is, the adhesion after the band is pressed. The resistance value of the layer is set to 10@4 Ω or less.

０以下とならしめることを原理としている。That is, in the present invention, the conductive powder is dispersed in a 1 cm"
When an adhesive tape containing one or more of these is attached around or partially around the maximum outer diameter part of a cathode ray tube and a pressure band is tightened to perform explosion-proof treatment, the heat and pressure of the pressure band causes The fluid component in the adhesive tape flows, and the conductive materials such as metal powder contained therein have a slow flow rate, so the density of the conductive material increases directly under the pressure band, causing the conductive materials to come into contact with each other. Or, since the same condition occurs on the band and cathode ray tube surface as they are close to each other, the resistance value is sufficient to transfer static electricity from the glass surface to the band, that is, 104.
The principle is to normalize the value to 0 or less.

These resins are used alone or in combination, and the amount of coating and impregnation is in the range of 10 g/m2 to 600 g/m'. Supports 11.15 used include glass cloth,
Fiber cloth such as rayon or cotton cloth or polyester film is used, and the thickness is 50 μm depending on the design of the cathode ray tube.
The diameter is selected from those in the range of m to 400 μm. In the figure, 14 and 18 are conductive materials such as metal powders of iron, copper, aluminum, silver, and their alloys, or carbon powder embedded in the adhesive, and the particle size of this powder is 300 μm.
m or less and the main distribution particle size is within the range of 25 μm to 300 μm. When the main particle size distribution is 25 μm or less, it is necessary to use a very large amount to exhibit the effects of the present invention, resulting in disadvantages such as cost disadvantages and deterioration of adhesive properties due to large amounts of use. In addition, when particles with a main particle size distribution of 300 μm or more are used, these particles may locally receive pressure from the pressure band and damage the surface of the cathode ray tube, reducing the explosion-proof function or partially damaging the surface of the cathode ray tube. Particles can flake off and touch circuits, creating instability that can cause serious trouble. The amount of these powders to be added may be 1 or more in terms of a converted dispersion amount per 1 cm' of the surface area of the adhesive tape, and if it is 10 5 or more, disadvantages such as high cost and deterioration of adhesive properties will occur. FIG. 4 is an enlarged view of the state in which the smoke prevention tape of the present invention shown in FIG. The agent layer 12 is softened and melted, and the organic flowable component flows and passes through the glass cloth 11 which is the support and becomes integrated, and after cooling, metal particles are formed directly under the band where a pressure of at least 1 kg/cm2 or more is applied. stop in contact with each other or in effective proximity, and the interlayer resistance of the adhesive tape becomes 1040 or less, a resistance value sufficient to transfer static electricity on the surface of the cathode ray tube to the band.
