Abstract
Description
本発明は、山陰地方に特有の瓦用釉薬である「来待釉(きまちゆう)」に関する。 The present invention relates to “Kachimachi Yu” which is a glaze for tiles peculiar to the San-in region.
従来より、山陰地方、特に島根県では、赤味の強い茶色に発色し、且つ、受光具合により光沢と色合いに微妙な変化を呈するラスター調の釉面外観(この様な外観を以下、「来待虹彩(まきちこうさい)」と指称する。)を有する瓦が見受けられた。
来待釉は、古くは松江市宍道町にて産出の来待錆石を原料とし、近年では安定供給を図るべく、より入手が容易な窯業原料を数種類配合して調製しており、伝統の独特な虹彩及び色合いを醸し出させるためには、釉薬への鉛の含有が不可欠であった。
Traditionally, in the San'in region, especially Shimane Prefecture, it has a reddish brown color and a subtle appearance of a raster-like surface that exhibits a subtle change in luster and color depending on the condition of light received. A roof tile with the name "Machichisai" was found.
In the old days, Kuramata is made from rust stone produced in Matsue City, Shinji, and in recent years it has been prepared by blending several types of ceramic raw materials that are easier to obtain. The inclusion of lead in glazes was indispensable for creating unique irises and colors.
尚、出願人が知り得る範囲では、上記背景技術が開示されている先行技術文献は存在しないが、当該技術は、実際に実施されている。 In addition, as far as the applicant can know, there is no prior art document that discloses the above-mentioned background art, but the technique is actually implemented.
ところが、鉛は有害であるため、製造に従事する者の安全確保、環境破壊の防止の点から、鉛を含有しない釉薬による来待虹彩瓦の製造が望まれていた。 However, since lead is harmful, it has been desired to produce a visiting iris tile with a glaze that does not contain lead from the viewpoint of ensuring the safety of those engaged in the manufacture and preventing environmental destruction.
本発明は、上記の課題に鑑み、釉薬組成をゼーゲル式にて、R2 0(R2 0=K2 0+Na2 0+Li2 0)が0.10〜0.40、R0(R0=Ca0+Mg0+Ba0+Zn0+Sr0)が0.90〜0.60、Al2 O3 が0.12〜0.52、Fe2 O3 が0.08〜0.24、P2 O5 が0.01〜0.12、SiO2 が2.20〜4.50、TiO2 が0.05〜0.30、WO3 が0.01〜0.21、とすることによって、鉛を含有させずに、来待釉に特有の虹彩及び色合いを発現させる様にして、上記の課題を解決する。 In the present invention, in view of the above problems, the glaze composition is Zegel's formula, where R 2 0 (R 2 0 = K 2 0 + Na 2 0 + Li 2 0) is 0.10-0.40, and R0 (R0 = Ca0 + Mg0 + Ba0 + Zn0 + Sr0) is 0.90 to 0.60, Al 2 O 3 is 0.12 to 0.52, Fe 2 O 3 is 0.08 to 0.24, P 2 O 5 is 0.01 to 0.12, and SiO 2 is 2.20 to 4.50, TiO 2 is 0.05 to 0.30, and WO 3 is 0.01 to 0.21, so that an iris and The above-described problems are solved by developing a hue.
要するに本発明は、釉薬組成を特許請求の範囲の請求項1に記載の通りとしたので、この釉薬の使用により、瓦に来待虹彩を付与することが出来、無鉛であるため、製造に従事する者の健康を害する虞がなく、また釉薬が製造施設外に万一漏れても、自然に対する負担が小さく、環境保全を図ることが出来る。 In short, since the glaze composition of the present invention is as described in claim 1 of the scope of claims, the use of this glaze can impart a welcome iris to the roof tile and is lead-free. If the glaze leaks out of the manufacturing facility, the burden on nature is small and environmental conservation can be achieved.
更に、請求項2に記載の通りとすることによって、来待虹彩の品質を維持したまま、焼成温度についての適応範囲が広がり、製造が容易になるばかりか、品質が安定し、製造歩留りを向上させることが出来る。 In addition, by maintaining the quality of the iris, the application range for the firing temperature is widened and the production is facilitated, the quality is stabilized, and the production yield is improved. It can be made.
B2 O3 の組成範囲を0.40以下、V2 O5 の組成範囲を0.20以下、ZrO2 の組成範囲を1.10以下に設定して加えたので、釉薬の溶融程度、発色の赤味の程度及び熱膨張率をより緻密に調整して、適用範囲を拡張できると共に、品質の更なる安定化を図ることが出来る等その実用的効果甚だ大である。 The composition range of B 2 O 3 was set to 0.40 or less, the composition range of V 2 O 5 was set to 0.20 or less, and the composition range of ZrO 2 was set to 1.10 or less. The degree of redness and the coefficient of thermal expansion can be adjusted more precisely to expand the application range and to further stabilize the quality.
以下、本発明の瓦用釉薬につき詳細に説明する。
この釉薬は、ゼーゲル式にて、次の様に表される組成に調製されたものである。
1) R2 0 : 0.10〜0.40
2) R0 : 0.90〜0.60
3) Al2 O3 : 0.12〜0.52
4) Fe2 O3 : 0.08〜0.24
5) P2 O5 : 0.01〜0.12
6) SiO2 : 2.20〜4.50
7) TiO2 : 0.05〜0.30
8) WO3 : 0.01〜0.21
Hereinafter, the tile glaze of the present invention will be described in detail.
This glaze is prepared by the Seegel formula and having the following composition.
1) R 2 0: 0.10 to 0.40
2) R0: 0.90 to 0.60
3) Al 2 O 3 : 0.12 to 0.52
4) Fe 2 O 3: 0.08~0.24
5) P 2 O 5 : 0.01 to 0.12
6) SiO 2 : 2.20 to 4.50
7) TiO 2: 0.05~0.30
8) WO 3: 0.01~0.21
ここで、R2 0は、K2 0、Na2 0及びLi2 0の総和(つまり、R2 0=K2 0+Na2 0+Li2 0)であり、R0は、Ca0、Mg0、Ba0、Zn0及びSr0の総和(つまり、R0=Ca0+Mg0+Ba0+Zn0+Sr0)である。
各範囲の値は、モル比であり、釉薬配合中に含有されるR2 0とR0のモル値の合計を1に換算し、その1の中でのR2 0とR0をモル比で表すと共に、Al2 O3 〜WO3 の値は、各成分の釉薬配合中での含有量をR2 0+R0=1に対するモル比で表したものである。
Here, R 2 0 is the sum of K 2 0, Na 2 0 and Li 2 0 (that is, R 2 0 = K 2 0 + Na 2 0 + Li 2 0), and R0 is Ca0, Mg0, Ba0, Zn0 and The sum of Sr0 (that is, R0 = Ca0 + Mg0 + Ba0 + Zn0 + Sr0).
The value of each range is a molar ratio, and the total of the molar values of R 2 0 and R 0 contained in the glaze formulation is converted to 1, and R 2 0 and R 0 in 1 are represented by the molar ratio. In addition, the values of Al 2 O 3 to WO 3 represent the content of each component in the glaze formulation as a molar ratio with respect to R 2 0 + R0 = 1.
そして、R2 0及びR0は、釉薬の発色に影響し、Fe2 O3 とP2 O5 との組み合わせにより発色する来待釉に特有の赤茶錆色の発色を助長すると共に、釉薬の溶融程度、熱膨張率にも影響し、幾多の試験の結果により、発色具合、溶融程度、熱膨張率の瓦本体との相対関係が全て良好となるのは、上記の 1) 、 2) 、 4) 及び 5) の範囲が適切であることが判明した。
又、TiO2 及びWO3 は、釉面外観風合いに影響し、来待釉に特有のラスター調の風合いを程良く発現させるためには、上記の 7) 及び 8) の範囲が適切であることが判明した。
因みに、Al2 O3 及びSiO2 は、釉薬の母体であり、窯業技術の常識に従い、両者の比率により、溶融程度、熱膨張率を調整すれば良いが、その他の成分、それらの適切範囲との組合わせの下では、上記の 3) 及び 6) の範囲が適切であることが判明した。
要するに本発明は、上記の 1) 〜 8) に記載の成分の全てを組合わせて、その上、モル比を 1) 〜 8) の所定範囲に夫々設定して、はじめて従前の来待釉と同等の来待虹彩を発現するものである。
R 2 0 and R 0 affect the color development of the glaze, promote the red-brown rust color unique to the traditional Japanese amber that is colored by the combination of Fe 2 O 3 and P 2 O 5, and melt the glaze The degree of color development, the degree of melting, and the relative relationship of the coefficient of thermal expansion with the tile body are all good according to the results of various tests. ) And 5) were found to be appropriate.
In addition, TiO 2 and WO 3 affect the appearance of the surface of the surface, and the above ranges 7) and 8) are appropriate in order to adequately express the raster-like texture that is unique to the visitor. There was found.
Incidentally, Al 2 O 3 and SiO 2 are the bases of glazes, and according to the common sense of ceramic technology, the degree of melting and the coefficient of thermal expansion may be adjusted by the ratio of both, but other components, their appropriate ranges and Under the above combination, the above 3) and 6) were found to be appropriate.
In short, the present invention combines all of the components described in 1) to 8) above, and sets the molar ratios within the predetermined ranges of 1) to 8) for the first time. An equivalent arrival iris is expressed.
上記の 1) 〜 8) の組成に加えて、溶融程度を調整するために、B2 O3 を0.40以下の範囲で添加したり、また発色の赤味の程度を調整するために、V2 O5 を0.20以下、ZrO2 を1.10以下の範囲で添加しても良い。
ZrO2 は、発色の赤味の程度に影響するだけではなく、釉薬の熱膨張率にも影響し、その添加により、熱膨張率を低下させるが、やはり窯業技術の常識に従い、ZrO2 とSiO2 の総量、この総量とAl2 O3 とのモル比により、本釉を適用する瓦本体の熱膨張率との相対関係を調整すれば良い。
In order to adjust the degree of melting in addition to the compositions of 1) to 8) above, B 2 O 3 is added in a range of 0.40 or less, or the degree of redness of color development is adjusted. V 2 O 5 of 0.20 or less, may be added ZrO 2 1.10 in the following range.
ZrO 2 not only affects the degree of redness of color development, but also affects the thermal expansion coefficient of the glaze, and its addition lowers the thermal expansion coefficient. However, according to the common sense of ceramic technology, ZrO 2 and SiO What is necessary is just to adjust the relative relationship with the thermal expansion coefficient of the tile main body to which the main fence is applied by the total amount of 2 and the molar ratio of this total amount to Al 2 O 3 .

The amount of glazing was 0.6 to 0.9 gr / cm 2 in terms of glaze dry powder.
Next, the glazed product was baked at 1200 ° C., and the glazed surface of the obtained baked product was visually confirmed to comprehensively evaluate the appearance of the waiting iris (color development and texture). The results are shown in the lower column of each table.
As shown in each table, good results were obtained within the range shown in paragraph [0009]. Although not shown in the table, outside the range of each component shown in paragraph [0009], the color development was poor, the redness was insufficient, or there was no raster-like texture, which was poor.
