Abstract

PURPOSE:To easily obtain a flame spray-coated tile having an indented pattern in high efficiency, by flame-spraying a glaze to a tile substrate and pressing an indented surface of a heat-resistant embossing mold and/or a heat-resistant fibrous material against the surface of the glaze while the surface is still in a hot viscous state. CONSTITUTION:A glaze 3 (e.g. SiO2 frit) is sprayed with a flame spraying burner 2 to the surface of a preparatorily baked tile substrate 1 to form a glaze layer 4. While the glaze layer 4 is still in a hot and viscous state, it is pressed with an embossing plate of a heat-resistant embossing mold 5 having indentations 6 corresponding to a letter or a pattern. An indented pattern 7 is formed on the surface of the glaze 4 and, at the same time, the surface is smoothened by the pressure of the embossing mold 5 to obtain a flame spray-coated tile having indented pattern 7. The indented pattern may be formed by pressing a fibrous heat-resistant material such as ceramic fiber in place of the embossing mold 5 against the glaze layer 4.

Cooling generates thermal stress in the base material, which tends to cause defects such as warping and deformation in the product. Furthermore, since a furnace is used for firing, there are equipment limitations, for example, making it difficult to easily apply glaze on site.

He developed a method of baking a glaze layer onto the surface of a tile base material by thermal spraying, and published this as Japanese Patent Application No. 145090/1983. When using this method, the tile base material on which the glaze is baked is already fired. Furthermore, since the firing temperature of the tile base material is higher than that of the glaze baking, even if the tile base material is sometimes heated during the glaze baking, defects such as warping and deformation are less likely to occur in the base material.

文字等を表現することが可能となる。The glaze layer immediately after being formed by thermal spraying is in a high temperature and highly viscous state. Therefore, when a pressing mold is pressed against this glaze layer, the surface of the glaze layer is easily deformed in accordance with the unevenness of the pressing mold and/or the fibrous heat-resistant material. In this regard, with the conventional method of firing the glaze in a furnace, if you want to create unevenness on the glaze layer using a pressing mold, it is necessary to heat the fired glaze layer again to a high temperature to make it viscous. There is. In contrast, in the present invention, since the properties of the glaze layer immediately after thermal spraying are utilized, unevenness can be easily imparted without the need for reheating. In addition, by adjusting the timing of pressing the mold and/or fibrous heat-resistant material onto the glaze layer, accurate patterns can be created with a small amount of pressing force.
It becomes possible to express characters, etc.

以下、図面を参照しながら、実施例により本発明の特徴

図である。FIG. 1 is a diagram illustrating step by step the process of manufacturing a thermal spray tile having a glaze layer provided with irregularities in this example.

タイル基材１は、予め焼成されたものである。The tile base material 1 is fired in advance.

ーナ２により釉薬３を溶射する。As the material of the tile base material 1, ceramic plates made of various oxide materials, metal plates, etc. are used. As shown in FIG. 1(a), a glaze 3 is thermally sprayed onto this tile base material 1 using a thermal spray burner 2.

厚みをもつ釉薬層４が形成される。As the glaze 3, a normal S r O2-based glaze is used. This glaze 3 is heated by a thermal spray flame, becomes molten, and adheres to the surface of the tile base material 1. In this way, a glaze layer 4 having a thickness of 0.5 to 2.0 m is formed on the surface of the tile base material 1.

形成直後の釉薬層４は、高温で粘性の高い状態にある。The glaze layer 4 immediately after being formed is in a high temperature and highly viscous state.

そこで、この状態の釉薬層４に対して、第１図（ｂ）に
示すように、押し型５を押し付ける。Therefore, a pressing mold 5 is pressed against the glaze layer 4 in this state, as shown in FIG. 1(b).

することもできる。The pressing mold 5 is made of a heat-resistant material such as a steel plate, and has projections and depressions 6 formed on its pressing surface to correspond to characters, patterns, etc. to be provided on the glaze layer 4. Alternatively, instead of the illustrated press die 5, it is also possible to press a fibrous heat-resistant material such as ceramic fiber. Furthermore, this fibrous heat-resistant material can also be used in combination with the press die 5.

し型５の押圧時期を、釉薬層４が３００℃以上の温度範
囲にある時期とすることが好ましい。The higher the temperature of the glaze layer 4, the smaller the pressing force of the pressing die 5 becomes. However, when the temperature of the glaze layer 4 is too high, a part of the glaze layer 4 flows after being pressed, and accurate letters, patterns, etc. cannot be applied to the glaze layer 4. On the other hand, as the temperature of the glaze layer 4 decreases, the flow phenomenon decreases and it becomes possible to form accurate letters, patterns, etc., but the pressing force increases. Therefore, in order to satisfy both conditions, it is preferable to press the pressing mold 5 at a time when the glaze layer 4 is in a temperature range of 300° C. or higher.

釉薬層４の表面には、押し型５の押圧によって第１図（

As shown in C), an uneven pattern 7 is formed.

表面も平滑化される。Further, by pressing the pressing die 5, the surface of the glaze layer 4 is also smoothed.

Or, it has the function of this mold release agent and the glaze layer 4
A resin tape with glass beads, silica sand, etc., which is transferred to give a decorative effect etc. to the surface of the glaze layer 4, is pressed into the mold 5.
It is also possible to paste it on the pressing surface.

A layer can be formed on top of the tile base. Moreover, since the surface of the glaze layer is made smooth by the pressing of the press, a tile from which stains can be easily removed can be obtained. In this way, according to the present invention, it has become possible to efficiently produce thermal sprayed tiles with high commercial value.
