品の表面に下地処理を施す。<Prior art> In this type of manufacturing method, in order to prevent the glaze applied to the surface of the cement product, especially the cellular cement product, from being absorbed into the cement product,
Alternatively, in order to prevent cracks, penetrations, pinholes, etc. from occurring in the glaze fused to the surface of the cement product, the surface of the cement product is subjected to surface treatment before the glaze is applied.
例えば、特開昭61−6188号公報に開示されてい
るように、セメント製品の表面にセメントペース
トをすり込んで目止めを施す。 For example, as disclosed in Japanese Unexamined Patent Publication No. 61-6188, cement paste is rubbed onto the surface of a cement product to seal it.
また、特開昭59−92981号公報に開示されてい

る。 Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 59-92981, the surface of a cement product is fired at a temperature of 200 to 800°C to remove adhering water or crystallized water existing on the surface. Modified into a ceramic layer.
＜発明が解決しようとする問題点＞
ところが、前者の従来技術においては、セメン

止めを施すので、セメントペーストのすり込みに
多くの手間が掛り、下地処理の能率が高くない。<Problems to be Solved by the Invention> However, in the former prior art, cement paste is rubbed onto the surface of the cement product to seal it, so it takes a lot of time and effort to rub the cement paste, and it takes a lot of time to prepare the surface. Not very efficient.
また、後者の従来技術においては、釉薬を融着
させるために焼成する外に、下地処理のために焼
成し、２度焼成するので、焼成エネルギを多く要
し、焼成費が高い。 Furthermore, in the latter conventional technique, in addition to firing to fuse the glaze, firing is performed to prepare the base and fired twice, which requires a large amount of firing energy and increases firing costs.
本発明の目的は、上記のような従来の問題点を
解決することである。 An object of the present invention is to solve the conventional problems as described above.
＜問題点を解決するための手段＞
本発明は、セメント製品の表面に釉薬を融着さ
せるための下地処理に釉薬を用いるものである。<Means for Solving the Problems> The present invention uses a glaze for base treatment to fuse the glaze to the surface of a cement product.

で焼成して、上層の釉薬を下層の軟化した釉薬を
介してセメント製品の表面に融着し、セメント製
品を養生することを特徴とする施釉セメント製品
の製造法である。 That is, a glaze is applied to the surface of a cement product and dried, a glaze that melts at a lower temperature than the glaze is applied on top of the glaze, and the glaze in the lower layer is fired at a temperature that softens but does not melt the glaze in the upper layer to soften the glaze in the lower layer. This method of manufacturing glazed cement products is characterized by curing the cement products by fusing the glaze to the surface of the cement products.

収されることがなく、また、熔融しないが、軟化
して流動性を帯びるので、セメント製品表面の凹
凸に馴染み、セメント製品の表面を目止めする役
割を果たすことになる。<Function> In the production method of the present invention, the lower glaze softens but does not melt, so it is not absorbed into the cement product, and it does not melt, but softens and becomes fluid. It adapts to the unevenness of the cement product surface and plays the role of sealing the surface of the cement product.
また、上層の釉薬は、熔融して融着するので、
ガラス質の光沢を発して美観を呈し、また、下層
の釉薬によつてセメント製品の表面が目止めされ
ているので、上層の釉薬の表面は、滑らかな釉面
になり、貫入やピンホール等が発生しない。 In addition, the upper layer glaze melts and fuses, so
The surface of the cement product is sealed by the lower layer of glaze, giving it a glassy luster and a beautiful appearance.The upper layer of glaze creates a smooth glazed surface, preventing penetrations and pinholes. does not occur.
セメント製品が気泡セメント製品の場合、下層
の釉薬が流動性を帯びてセメント製品表面の気泡
に侵入するので、下層の釉薬とセメント製品の密
着性がよい。下層の釉薬と上層の釉薬の密着性が
よいのは明らかである。 When the cement product is a cellular cement product, the glaze in the lower layer becomes fluid and penetrates into the air bubbles on the surface of the cement product, so the adhesion between the glaze in the lower layer and the cement product is good. It is clear that the adhesion between the lower layer glaze and the upper layer glaze is good.

There are alkaline glazes, alkali-lime glazes, lime glazes, feldspar glazes, boric acid glazes, etc. Furthermore, fritted glazes made by heating and melting these glazes and rapidly cooling them into a glassy state may be used as they are, or fritted glazes made by mixing feldspar, clay, siliceous powder, alumina powder, etc. with this fritted glaze may be used. You may also use
上層の釉薬は、下層の釉薬より、20〜300℃、
好ましくは50〜150℃低い温度で熔融するものを
用いる。 The upper layer glaze is heated at 20 to 300°C, lower than the lower layer glaze.
Preferably, a material that melts at a lower temperature of 50 to 150°C is used.

薬の表面に貫入が生じ難くなる。 If a lower layer glaze is used that has less thermal expansion than the upper layer glaze but more than the cement product, penetration into the surface of the fused upper layer glaze is less likely to occur. In general, the thermal expansion coefficient of the low-temperature glaze used for the upper layer glaze is greater than that of the cement product, and the shrinkage due to cooling after firing is greater for the low-temperature glaze than the cement product, and the difference in the amount of shrinkage between the two is This is the cause of penetration. If a layer of glaze with a thermal expansion coefficient intermediate between the glaze with a large thermal expansion coefficient and a cement product with a small thermal expansion coefficient is provided, the difference in the amount of shrinkage between the upper layer glaze and the lower layer glaze will be reduced. Penetration becomes difficult to occur on the surface of the upper layer glaze.
下層の釉薬又は上層の釉薬を施す方法には、は
け塗り、吹付け、ローラ塗布やどぶ漬け等が用い
られる。 Brushing, spraying, roller coating, gluing, etc. are used to apply the lower layer glaze or the upper layer glaze.
下層の釉薬の乾燥は、常温〜150℃の温度で行
うことができる。 The lower layer glaze can be dried at a temperature between room temperature and 150°C.
焼成温度は、下層の釉薬が軟化するが熔融しな
い温度であつて、上層の釉薬が熔融する温度であ
る。 The firing temperature is the temperature at which the lower layer glaze softens but does not melt, and the upper layer glaze melts.
焼成時間は、５〜120分が適当である。 The appropriate firing time is 5 to 120 minutes.
上層の釉薬が融着したセメント製品を養生する

法は、強度の発現に最も好ましい。また、水中養
生法は、数分間で強度が発現する。 An autoclave curing method, a steam curing method, or an underwater curing method is used to cure the cement product to which the upper layer glaze is fused. Autoclave curing is most preferred for strength development. In addition, the water curing method develops strength in a few minutes.
