組成物に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a color television tube panel and funnel made of a low-melting glass powder and a low-expansion refractory filler that are sealed at a relatively low temperature. The present invention relates to a sealing composition used for sealing.
［従来の技術］
高い温度での封着は、封着される物品、例えば、パネル

からも封着温度の低下が要望されていた。このような要
望を満たすものとしてカラーテレビジョン管のパネルと

含有される。[Prior Art] Sealing at high temperatures tends to cause deformation of the articles to be sealed, such as panels and funnels, and there has been a desire to lower the sealing temperature from the viewpoint of energy conservation. To meet these demands, we have developed a set Ij that can seal the color television tube panel and funnel at a low temperature of 420°C or less.
i. Something has been proposed. Such a composition consists of an inorganic component of glass powder and a refractory filler, and the refractory filler contains one having a large particle size of 200 mesh or more.
しかしながら、かかる組成物で封着されたブラウン管は
、性能上の不具合を生じた場合、パネルとファンネルを
剥離し再生する工程いわゆるサルベージ工程でパネル、
ファンネルにクラックが発生し易い。そのためパネルフ
ァンネルの再利用が充分に行えず生産コストの上昇を生
じるという問題点かあった。However, when a cathode ray tube sealed with such a composition develops a performance defect, the panel and funnel are peeled off and recycled in a so-called salvage process.
Cracks are likely to occur in the funnel. Therefore, there was a problem that the panel funnel could not be reused sufficiently, resulting in an increase in production costs.
［発明の解決しようとする問題点］
本発明は従来技術か有していた上述の問題点を解消し、

の提供を目的とする。[Problems to be solved by the invention] The present invention solves the above-mentioned problems that the prior art had,
To provide a sealing composition that can sufficiently reprint panels and funnels without causing cracks in them during a salvage process.
［問題点を解決するための手段］

易い。As the low melting point glass powder of the present invention, any glass that softens at low temperature can be used, pbo-B, 0. -ZnO
Those that crystallize at low system temperatures are preferred. Refractory fillers are used to control the coefficient of thermal expansion of the composition. If this refractory filler contains large particles, it will cause cracks in panels and funnels during the salvage process. That is, the sealed portion of the panel and funnel is immersed in a nitric acid solution to partially remove the frit, and the wedge-shaped sealed portion is repeatedly poured (or immersed) in cold water and hot water.
Therefore, a method of peeling by applying thermal stress is used. At this time, the panel or part of the funnel tends to crack or expand.
従って、耐火物フィラーの粒径は２００メツシュ以下か
好ましく、３００メツシュ以下か特に望ましい。Therefore, the particle size of the refractory filler is preferably 200 mesh or less, particularly preferably 300 mesh or less.

膨張係数の小さいものてあれば特に限定されない。具体
的にコージェライト、β−ユークリプタイト、β−スポ
ジューメン、ジルコン、チタン酸鉛か例示される。Such a refractory filler is not particularly limited as long as it has good wettability with glass and a small coefficient of expansion. Specific examples include cordierite, β-eucryptite, β-spodumene, zircon, and lead titanate.

る。[Effect: If large particle size is present in the refractory filler,
Because of its low expansion, large stress acts in its vicinity. In other words, if there is a large filler on the bonding surface of the object to be sealed, a larger tensile stress is applied to the bonding surface near the filler than in other parts, and if thermal shock is applied to this during the salvage process, the object to be sealed may crack. It is thought that the cracks will propagate to the panels and funnels.
