Description
【発明の詳細な説明】 産業上の利用分野 本発明は、抗火石を陶土と混合した窯業焼結品の製造方
法に関する。Description: TECHNICAL FIELD The present invention relates to a method for producing a ceramic sintered product in which anti-firestone is mixed with porcelain clay.
従来の技術及び発明が解決しようとする課題 従来、ガラス化原料としては長石が陶磁器原料として広
く用いられていたが、火山ガラスは不純物を多量に含む
ため、全国各地に多量に存在するにもかかわらず、ほと
んど利用されていなかつた。BACKGROUND OF THE INVENTION Conventional techniques and problems to be solved by the invention Conventionally, feldspar has been widely used as a raw material for ceramics as a vitrification raw material, but since volcanic glass contains a large amount of impurities, it may be present in large amounts throughout the country. No, it was rarely used.
また、嵩比重が低く、焼成による収縮が大きいなどの欠
点がある。Further, there are drawbacks such as low bulk specific gravity and large shrinkage due to firing.
本発明はこのような火山ガラスのうち抗火石を窯業焼結
品として有効に利用しようとするものである。The present invention intends to effectively utilize anti-fire stone among such volcanic glass as a ceramic sintered product.
課題を解決するための手段 本発明は抗火石に顔料を一体的に添加した粗粒を形成
し、この粗粒を陶土と混合して成形した後焼結すること
を特徴とするものである。Means for Solving the Problems The present invention is characterized by forming coarse particles in which a pigment is integrally added to anti-firestone, mixing the coarse particles with porcelain clay, and then sintering the mixture.
発明の効果 抗火石は 多孔質で軽量である 軟化点が低い 溶融状態における粘性が高い 焼成温度幅が広い 熱膨張率が小さい 顔料の発色が良い 等の性質を有するため、 着色し易い 生素地、焼結品とも他の材料となじみ易い 低温で溶融し、高温でも安定して焼結安定性が高く
大型製品が作り易い 装飾効果が大きい 焼結により素地の表面で収縮して凹部が形成され、
床タイルの場合に滑り止めとなる等の効果がある。Effect of the Invention Anti-firestone is porous and lightweight, has a low softening point, has high viscosity in the molten state, has a wide firing temperature range, has a small coefficient of thermal expansion, and has good properties such as good pigment coloring. Sintered products are easily compatible with other materials. Melted at low temperature, stable at high temperature, and easy to make large products. Great decorative effect. Sintering causes shrinkage on the surface of the base material to form recesses.
In the case of floor tiles, it has the effect of preventing slipping.
実施例１ 抗火石を10〜30メツシユの粒度に調整して粗粒を作り、
これに、バインダー10％、長石20％（耐火度調整材）、
顔料５％、さらに水を加えて上記粗粒と混合することに
より、その粗粒の表面に被覆剤を覆つた被覆粗粒を造
り、この粗粒を融点約1250℃に調整した通常の乾式タイ
ル坏土に10％混合し、プレスで乾式成形し、1250℃にて
焼成したところ、表面に着色された粗粒が凹面を作り、
斑点模様を呈し、且つ、ひび割れもなく、十分な強度を
有するタイルが得られた。Example 1 An anti-fire stone was adjusted to a particle size of 10 to 30 mesh to make coarse particles,
To this, 10% binder, 20% feldspar (fire resistance adjustment material),
By adding 5% of pigment and further water and mixing with the above-mentioned coarse particles, coated coarse particles in which a coating agent is covered on the surface of the coarse particles are prepared, and the normal dry tile in which the coarse particles are adjusted to a melting point of about 1250 ° C. When mixed with 10% of kneaded clay, dry-molded with a press and baked at 1250 ° C., colored coarse particles make a concave surface,
A tile having a speckled pattern and no cracking and having sufficient strength was obtained.
