着剤層が２ 。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an explosion-proof cathode ray tube in which a reinforcing ring surrounding a core is heat-attached to the face panel portion of a cathode ray tube body, and one side of the cathode ray tube is made of a porous sheet as a core material. A tape having a room-temperature adhesive layer on one side and a room-temperature non-adhesive thermoplastic synthetic resin layer on the other side is placed between the face panel portion and the reinforcing ring. 2 adhesive layers.
前記フェースパネル部側となる向きに介在させることに
よって、補強効果の向上および補強環体装着時における
作業性の改善をはかったものである。By interposing the reinforcing ring toward the face panel side, the reinforcing effect and the workability when attaching the reinforcing ring are improved.

体に対する前記補強環体ｄ結合を良好に保っている。Generally, in explosion-proof cathode ray tubes, which have a reinforcing ring surrounding the core part on the face panel of the cathode ray tube body,
By interposing a tape adhesive at room temperature between the face panel portion and the reinforcing ring, the reinforcing ring d is well bonded to the cathode ray tube body.
前記テープとしては、両面に常温粘着性接着剤層を有す

嵌着された補強環体に滑りを起させやすく、この滑りに
よって補強環体が位置ずれを起すと、補強効果、したが
って防爆効果に低下をきたす。As the above-mentioned tape, so-called double-sided adhesive tapes having a room-temperature adhesive layer on both sides are often used. In particular, double-sided adhesive tapes with an adhesive layer formed of natural rubber or synthetic rubber, etc. The reinforcing ring wrapped or fitted thereon is likely to slip, and if this slippage causes the reinforcing ring to shift in position, the reinforcing effect and, therefore, the explosion-proofing effect will be reduced.

小さいのが普通であるから、１巻の実質的なテープ量は
非常に少々く、陰極線管量産工程でのテープ補給作業が
繁雑となシ、これが作業性の改善を阻害する一因となっ
ていた。Furthermore, before being wrapped around the outer circumferential surface of the face panel of the cathode ray tube body, the double-sided adhesive tape is wound up with a release paper (commonly called a separator) in between. Since the diameter is usually small to prevent winding, the actual amount of tape in one roll is very small, and tape replenishment work in the mass production process of cathode ray tubes is complicated, which reduces work efficiency. This was a factor that hindered improvement.
本発明は、前述の諸点に留意してなされたもので、つぎ

を有している。In FIG. 1, a cathode ray tube body 1 consisting of a color picture tube is shown.
is reinforced by a reinforcing ring body 3 surrounding the face panel portion 2 and a table 4 provided between the face panel portion 2 and the reinforcing ring body 3. The reinforcing ring body 3 is obtained by seam welding one end edge 6 of a metal band 5 made of steel or the like and the other end edge 7 overlaid thereon, as shown in FIG. Tabular pieces for cathode ray tube installation 8 on the four corners

着力利用によυ巻装される。On the other hand, as shown in FIG. 3, the tape 4 includes a porous sheet 9 made of a woven fabric such as glass or cotton cloth or a mesh nonwoven fabric such as nylon or polyester, and a core material of the porous sheet 9. The reinforcing ring body 3 is made up of a room-temperature adhesive layer 1o provided on one surface of the sheet 9 and a room-temperature non-adhesive thermoplastic synthetic resin layer 11 provided on the other surface of the sheet 9. It is wrapped around the outer circumferential surface of the face panel section 2 before it is mounted, with the room-temperature adhesive layer 1o on the inside, by utilizing its adhesive strength.

はない。The room-temperature adhesive layer 1o can be formed by applying a thermosetting resin such as an epoxy resin or a rubber-based resin as a material, similar to the adhesive layer in a conventional single-sided adhesive tape. The thermoplastic synthetic resin layer 11, which is non-tacky at room temperature, can be formed by coating polyethylene, vinyl chloride resin, acrylic resin, or the like as a material, and the resin after coating is cured and has no tackiness at room temperature.
なお、両層１０，１ １の形成順序としては、まず合成
樹脂層１１を形成し、その硬化後に、接着剤層１０を形
成するのが好ましい。As for the order of formation of both layers 10 and 11, it is preferable to form the synthetic resin layer 11 first, and then form the adhesive layer 10 after it is cured.

プであるから、離型紙を用いることなくそれ自体を径太
に巻いておくことができる。したかって、陰極線管量産
工程でのテープ補給頻度を下げることにより、作業性を
改善することが可能となる。Since the tape 4 is a single-sided adhesive tape at least at room temperature, it can be wound into a thick diameter without using release paper. Therefore, by reducing the frequency of tape replenishment in the cathode ray tube mass production process, it is possible to improve work efficiency.

の一部分が融けて、やがて硬化する。After wrapping the tape 4 on the outer peripheral surface of the face panel portion 2 as described above, the metal reinforcing ring 3 is attached.
The tape is heated to a temperature within the range of C, and the tape stretched by this heating is made to fit onto the outer peripheral surface of the tape 4. When such a shrink-fitting method is adopted, a strong tightening force can be applied to the cathode ray tube body 1 by returning the reinforcing ring body 3 to room temperature, but the time and temperature required for the reinforcing ring body 3 to return to room temperature are Accordingly, the room temperature non-adhesive thermoplastic synthetic resin layer 11 of the tape 4
Part of it melts and then hardens.

まるので、きわめて良好な防爆効果が得られる。Then, not only a portion of the melted synthetic resin passes through the porous sheet 9 and appears on the face panel portion 2 side, but also a thermally deformed synthetic resin portion is generated around the reinforcing ring 3, so that the tape 4 and the reinforcing ring It is completely connected to body 3. Also,
Since the degree of adhesion between the tape 4 and the 7-ace panel portion 2 is further increased, an extremely good explosion-proof effect can be obtained.

熱する必要はない。Incidentally, in the above embodiment, the reinforcing ring body 3 was shrink-fitted, but the reinforcing ring body 3 does not need to be annular from the beginning, and after wrapping the tape 4 on the outer peripheral surface of the face panel portion 2. ,
A reinforcing ring metal band may be wrapped around this tape 4 and tightened to form an annular shape. In this case, the metal band is stiffened just before, during, or after wrapping, but there is no need to heat the glass bulb, which has a large heat capacity.

保持することができる。As an example, when the porous sheet 9 of the tape 4 is made of glass fiber, the warp yarns are G-150 yarns with a width of 30/26 [IIn width, and the weft yarns are G-75 yarns with a width of 25 yarns. This can be made with 26 fighting widths. Also,
The thermoplastic synthetic resin layer 11 has a thickness of 40 to 70 μm.
polyethylene resin can be used. in this case,
If, for example, an epoxy resin is used as the adhesive layer 1o, a portion of the adhesive layer 1o will pass through the porous sheet 9 due to the tightening of the metal band and exude toward the metal band. A composite adhesive effect is obtained by the molded synthetic resin and the thermosetting synthetic resin, and a stable adhesive state can be maintained even if the cathode ray tube is subsequently exposed to various thermal cycles.
