型して所望する形状の製品を得るようにしている。Usually, products made of foam material are lightweight and have excellent insulation properties.
In this case, the foamed material is foamed in a mold and then demolded to obtain a product in the desired shape.

つ面倒で長時間を要する工程が多くなリ、生産性が悪く
なるという欠点があった。However, when foaming the foam material in a mold, it is necessary to prepare a mold for each product size and shape, which requires time and effort for setup changes, and also has the disadvantage of increasing equipment costs. . Moreover, when forming a glazed surface on such a foamed material, in any case, the foamed material is first molded, then glazed, the whole is fired to vitrify the glaze, and the foamed material and glaze are combined. It is necessary to integrate the In short, at least the molding process of the foam molded product,
This requires a step of glazing and firing the foam molded body, and each step had to be performed separately. Therefore, it is complicated [1,
The disadvantage is that there are many cumbersome and time-consuming processes, resulting in poor productivity.

を備えた製品を得ることはできないでいた。Furthermore, when a glassy material is used as the foamed material, the mold release agent applied to the surface of the mold sticks to the surface of the foamed material, making it impossible to apply the glaze raw material to the surface of the foamed molded product. That is, it has not been possible to obtain a product with a glazed surface using a glassy foam material.
本発明は、従来の前記課題に鑑みてこれを改良除去した
ものであって、発泡成形と施釉焼成とを同時に行うこと
のできる施釉発泡セラミック製品の製造力性を提供せん

機質発泡セラミック製品を得ることが可能である。[Function] When a glaze is applied to the surface of a press-molded body of an inorganic foamed ceramic material and fired, the inorganic foamed ceramic material foams and at the same time, the glaze is vitrified and bonded to the inorganic foamed ceramic material. Thereafter, by cutting the unglazed surface of the fired body into a desired shape, it is possible to obtain a glazed inorganic foamed ceramic product.
以下に、本発明の方法を図面に示す実施例に基づいて説

発泡セラミック材料を準備する。火山性ガラス質鉱物は
、抗火石、流紋岩。1 to 4 show manufacturing steps according to an embodiment of the present invention. First, an inorganic foam ceramic material is prepared by mixing a fine main material made of a volcanic glassy mineral and a fine powder foaming agent. Volcanic glassy minerals are anti-pyrosite and rhyolite.

面←Ｆ面） ｌａの中央部分が膨隆する傾向にあるので
、この膨隆覆を見越して予め裏面ｌｂ例に四部２を形成
するようにしている。It is a mixture of one or more of pearlite, obsidian, whitebait, Ise silica sand, etc., finely crushed using a crusher, a mill, etc. Further, the fine powder foaming agent is a fine powder having an average particle size of 5 μm or less and is made of one or more of carbon, carbides such as silicon carbide, and nitrides such as silicon nitride. Next, such an inorganic foamed ceramic material is pressurized using a dry press machine or the like to obtain a press-molded body l having a desired shape as shown in FIG. This pressure-molded body 1 tends to swell at the center of the glazed surface ← F side of the pressure-molded body 1 during foaming in the firing process that will be carried out later. I am trying to form four parts 2 in the lb example.

Apply flII drug to the lc and place in tunnel furnace (not shown)
, and sintering is performed at a sintering temperature of 1180° C. for 30 hours. By this firing, the inorganic foamed ceramic material foams to form closed cells. Further, the glaze is vitrified at the same time as it is foamed, and is integrated with the inorganic foamed ceramic material. When the foaming is stabilized and cooled to normal temperature, the surfaces 1a and lc are approximately flat. This is because, during firing and foaming, the force that tends to swell the center side of the surface 1a turns into a force that flattens the four parts 2 formed on the surface 1b.
然る１には、このようにして得られた焼成体３の非施釉

であるので、燃える危険性がなく、吸水性もないので凍
害によるｔ０傷の虞れもない。In such a glazed foamed ceramic product 4, countless closed cells trap air, prevent heat conduction, and exhibit excellent heat insulation properties. In addition, since it is extremely lightweight and entirely made of glass, there is no risk of burning, and since it does not absorb water, there is no risk of t0 damage due to frost damage.
ところで、本発明は上述した実施例に限定されるもので

釉面等は適宜の変更が可能である。By the way, the present invention is not limited to the above-described embodiments, and, for example, the type of fd+ drug, the product shape, the glazed surface, etc. can be changed as appropriate.
