タイル用の釉薬に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a glaze for ceramic tiles, and more particularly to a glaze for ceramic tiles that can be fired quickly within a few tens of minutes to several hours.

の被膜を形成する。(Prior Art) Glaze is usually applied to ceramic tiles to change their use, to prevent contamination, and for other purposes. To apply a glaze to the surface of a tile, a glaze mixture consisting of various raw materials is pulverized with water to form a slurry (in the case of a raw glaze), and then this is poured onto the surface of the dried tile base. It is applied in a thick layer and fired together with the tile base. As the temperature rises, the glaze on the tile surface melts and then solidifies, forming a thin glass-like coating on the tile surface.

。(Problems to be Solved by the Invention) By the way, when tiles are fired quickly in a short period of time ranging from several tens of minutes to several hours, a sufficiently clean glazed surface cannot be obtained even if the above-mentioned glaze composition is varied. There were no problems that occurred. Rapid firing of tiles is usually carried out using a roller hearth kiln in a short period of time ranging from tens of minutes to several hours. (Because the melting reaction can only be carried out within a short period of time (for example, about 5 minutes if the firing time is 1 hour), and the reaction begins to solidify before it can be completed sufficiently.) For example, if the glaze contains components that generate gas, the glaze will solidify before gas generation is fully completed.
As a result, air bubbles remain in the shaft and form pinholes, which impair the aesthetic appearance of the tile surface.

フリットを製造する際一緒に又は別にフリット化され、
そのフリットの形態で釉薬中に配合されたことにある。(Means for Solving the Problems) The glaze of the present invention was devised to solve the above problems, and its gist is that it uses various materials such as siliceous raw materials, feldspathic raw materials, 2 limestone raw materials, etc. It is made by adding a predetermined amount of frit to different types of raw materials, and among these raw materials, specific types of raw materials that generate gas during the firing process, such as calcareous raw materials, are added to the frit together or separately when manufacturing the frit. became
This is because it was incorporated into the glaze in the form of a frit.

で生釉薬中に配合するようにしたのである。That is, the present invention provides a raw glaze made by blending a small amount of frit with a raw material obtained by pulverizing natural raw materials, in which a specific raw material is fritted in advance together with or separately from the frit, The frit form was incorporated into the raw glaze.
尚、本発明における生原料には、長石１！１原料。In addition, the raw materials in the present invention include 1:1 raw materials of feldspar.

融点等の特性を調整する目的で用いられる。On the other hand, a frit is a component of the glaze that has been vitrified in advance, and usually water-soluble components such as soda salt, potassium salt, and boric acid are fritted. This kind of frit, which is mixed in small amounts in raw glazes, is used exclusively for the purpose of adjusting the properties of the glaze, such as its a-expansion properties and melting point.

が用いられる。Therefore, in the present invention, in such a raw glaze, calcareous raw materials and other raw materials that do not originally need to be converted into free glazes, that is, components that generate gas during the firing process, are used in advance for purposes other than the above-mentioned purpose. Flinted. Conventional methods are used to form a flint, such as heating the raw material in a crucible for a certain period of time to melt it, then letting it flow out of the crucible, and rapidly cooling it with a cooling roll to form a frit.
（作用）
このようにして調製された本発明の釉薬は、焼成過程で
殆どカスを発生させない、ガスを発生させる釉薬中の生
原料が予めフリット化されているからである。(Function) The glaze of the present invention prepared in this way hardly generates scum during the firing process, because the raw raw materials in the glaze that generate gas are fritted in advance.
前述したようにフリット化は、材料をルツボ内で高温度
に（一般にタイルの迅速焼成時のピーク温度よりも高い

数時間）加熱して溶融させるものであり、従って生原料
はこのルツボ内における溶融反応の段階でガス発生反応
を完結してしまっていて、ト記焼成の段階ではガス発生
反応を殆ど行なわないからである。As previously mentioned, fritting involves heating and melting materials in a crucible at high temperatures (generally higher than the peak temperature during rapid firing of tiles) and for long periods of time (at least an hour, but sometimes several hours). Therefore, the gas generation reaction of the raw raw materials has been completed during the melting reaction stage in the crucible, and almost no gas generation reaction takes place during the firing stage.
而して釉薬が焼成段階でガスを発生させなげれば、固化
後の釉層中にも気泡、ピンホール等は生成しない、すな
わち表面状態が製品の品質を大きく左右するタイルにお
いて、且つ釉薬におけるガス発生反応のための十分な時
間がデえられない迅速焼成タイルにおいても美しい釉面
が得られるのである。Therefore, if the glaze does not generate gas during the firing stage, bubbles, pinholes, etc. will not be generated in the glaze layer after solidification. Beautiful glazed surfaces can be obtained even with rapidly fired tiles that do not have enough time for the gas-generating reaction.

ト化してしまうと釉薬の融点特性が変化してしまうが、
この場合には他の生原料を共にフリット化することによ
って融点特性を調整することができる。Of the raw materials that generate gas, there are calcareous raw materials, specific pigments, zirconium silicate as an opacifier, and zinc white (ZnO) 7p, but calcareous raw materials generate the most gas. Therefore, it is desirable to frit all of the calcareous raw material in advance; however, if all of the calcareous raw material is fritted, the melting point characteristics of the glaze will change.
In this case, melting point characteristics can be adjusted by fritting other raw materials together.
このように、本発明の釉薬を用いればタイル表面を美し

。As described above, by using the glaze of the present invention, it is possible to finish the tile surface beautifully, but the present invention also has the following features. In other words, certain types of raw materials (1
Since glazes (from seeds and beyond) are fritted in advance, the number of types of glaze ingredients is reduced, and this makes it possible to automatically measure and prepare glazes.
