〔請求項３〕
また本発明は、２ｍｍ厚さにおける波長７００ｎｍの透過率を波長６００ｎｍの透過率で除した値であるレッドネスレシオが５．０〜２４．０である請求項１又は２に記載の銅赤ガラスである。
本発明によれば、レッドネスレシオが５．０〜２４．０の良好な銅赤色を呈するガラスを安定して製造することができる。 [Claim 3]
Moreover, this invention is a copper red glass of Claim 1 or 2 whose redness ratio which is the value which remove | divided the transmittance | permeability of wavelength 700nm in 2 mm thickness by the transmittance | permeability of wavelength 600nm is 5.0-24.0. It is.
ADVANTAGE OF THE INVENTION According to this invention, the glass which exhibits favorable copper red color with a redness ratio of 5.0-24.0 can be manufactured stably.

本発明において、ガラス中のＣｕ２Ｏの量はＣｕ２Ｏ換算で０．０２５〜０．０８５ｍｏｌ％が好ましく、さらに好ましくはＣｕ２Ｏ換算で０．０３４〜０．０６５ｍｏｌ％である。Ｃｕ２Ｏの量が少なすぎると、着色成分である銅コロイドが減り発色に至らない。多すぎるとコスト高になる。
本発明において、銅赤ガラスに使用する量は従来よりもきわめて少量でよい。例えば、前記特許文献１における銅の量（Ｃｕ２Ｏ換算）は０．５〜０．９mass％（ｍｏｌ換算すると０．３５〜０．６３ｍｏｌ％）程度である。 In the present invention, the amount of Cu 2 O in the glass is preferably 0.025～0.085Mol% in Cu 2 O in terms of, even more preferably 0.034～0.065Mol% in Cu 2 O conversion. If the amount of Cu 2 O is too small, it does not lead to copper colloid reduces color is coloring component. Too much increases the cost.
In the present invention, the amount used for the copper red glass may be much smaller than the conventional amount. For example, the amount of copper (in terms of Cu 2 O) in Patent Document 1 is about 0.5 to 0.9 mass% (in terms of mol, 0.35 to 0.63 mol%).

ガラス中のＳの量（ＳＯ３換算値）は０．０２３〜０．０７８ｍｏｌ％が好ましく、さらに好ましくは０．０２９〜０．０６ｍｏｌ％である。Ｓ成分の原料は芒硝の他、硫化亜鉛、硫化鉄等の硫化物の形で添加してもよい。ガラス中のＳ（ＳＯ３換算値）の量が少なすぎると、核である硫化物の生成量が減り、銅コロイドが析出しなくなり、再加熱処理が必要になる。多すぎると、ＣｕＳやＦｅＳなどの硫化物の生成量が多くなりアンバー発色してしまう。 The amount of S in the glass (SO 3 equivalent value) is preferably 0.023 to 0.078 mol%, more preferably 0.029 to 0.06 mol%. The raw material of the S component may be added in the form of sulfides such as zinc sulfide and iron sulfide in addition to sodium sulfate. If the amount of S (SO 3 equivalent value) in the glass is too small, the amount of sulfides that are nuclei will be reduced, copper colloid will not precipitate, and reheating will be necessary. If the amount is too large, the amount of sulfides such as CuS and FeS increases, resulting in amber coloration.

ガラス中のＦｅの量（Ｆｅ２Ｏ３換算）は０．０１〜０．１３ｍｏｌ％、ＦｅとＳの量の比はＦｅ２Ｏ３換算モル値／ＳＯ３換算モル値で０．２以上が好ましい。Ｆｅが０．０１ｍｏｌ％よりも少なく、Ｆｅ２Ｏ３換算モル値／ＳＯ３換算モル値で０．２よりも少ないと、Ｓの量が十分であっても赤色の発色がきわめて薄いものとなり、Ｓの量が不十分であれば全く赤色に発色しない。Ｆｅの量を０．１３ｍｏｌ％よりも多くすることは無駄であり、また赤色部分の透過率が低くなって暗い色になる。
茶色（アンバー色）に発色する。 The amount of Fe in the glass (Fe 2 O 3 conversion) is 0.01 to 0.13 mol%, and the ratio of Fe and S is 0.2 or more in terms of Fe 2 O 3 conversion molar value / SO 3 conversion molar value. preferable. When Fe is less than 0.01 mol% and Fe 2 O 3 converted molar value / SO 3 converted molar value is less than 0.2, the red color is extremely thin even if the amount of S is sufficient, If the amount of S is insufficient, no red color is produced. It is useless to make the amount of Fe more than 0.13 mol%, and the red portion has a low transmittance, resulting in a darker color.
Colored brown (amber).

本発明は、ガラス中のＣｕとＳの量の比がＣｕ２Ｏ換算モル値／ＳＯ３換算モル値で０．７０〜１．５０であることを特徴とする。さらに好ましくは０．７８〜１．４５である。本発明において、再加熱処理を行うことなく良好な赤色を安定して得るためには、ＣｕとＳの量の比が重要であることが発見された。 The present invention is characterized in that the ratio of the amount of Cu and S in the glass is 0.70 to 1.50 in terms of Cu 2 O equivalent molar value / SO 3 equivalent molar value. More preferably, it is 0.78-1.45. In the present invention, it has been discovered that the ratio of the amount of Cu and S is important in order to stably obtain a good red color without performing reheating treatment.

Ｃｕ、Ｓ、Ｆｅ以外のガラス組成は、通常のソーダ石灰ガラスと同じでよい。例えば、ＳｉＯ２は６９〜７５ｗｔ％、Ａｌ２Ｏ３は０．５〜３．１ｗｔ％、Ｎａ２Ｏ、Ｋ２Ｏなどのアルカリ金属酸化物は合計１３〜１７ｗｔ％、ＣａＯ、ＭｇＯなどのアルカリ土類金属は合計５〜１４ｗｔ％とすることができる。また、必要に応じてＳｎＯ、ＺｎＯなどの金属酸化物を添加してもよい。 Glass compositions other than Cu, S, and Fe may be the same as those of ordinary soda lime glass. For example, SiO 2 is 69 to 75 wt%, Al 2 O 3 is 0.5 to 3.1 wt%, alkali metal oxides such as Na 2 O and K 2 O are 13 to 17 wt% in total, and alkali such as CaO and MgO. The total amount of earth metals can be 5 to 14 wt%. Moreover, you may add metal oxides, such as SnO and ZnO, as needed.

表１は、ガラス中のＣｕ、Ｆｅの量を固定し、Ｓの量の比を変化させた場合の色の変化を調べた結果である。ＣｕとＳの量は、それぞれＣｕ２Ｏ換算モル％、ＳＯ３換算モル％で表している。
また、図１は表１をグラフにしたものである。 Table 1 shows the results of examining changes in color when the amounts of Cu and Fe in the glass are fixed and the ratio of the amounts of S is changed. The amounts of Cu and S are represented by mol% in terms of Cu 2 O and mol% in terms of SO 3 , respectively.
FIG. 1 is a graph of Table 1.

Figure 2011241118
Figure 2011241118

表１及び図１から明らかなように、Ｃｕに対してＳが少なすぎるとガラスの色は青色になり、多すぎると茶色になる。
図１において、主波長（λd）５９３〜６２５ｎｍの良好な赤色（銅赤）となるとためのＣｕ２Ｏ換算ｍｏｌ値／ＳＯ３換算モル値は１．５０〜０．７０である。また、主波長（λd）６００〜６２５ｎｍのさらに良好な赤色（銅赤）となるためのＣｕ２Ｏ換算ｍｏｌ値／ＳＯ３換算モル値は１．４５〜０．７８である。
したがって、ＣｕとＳの量の比をこの範囲とすることで、良好な銅赤ガラスを安定して得ることができる。 As apparent from Table 1 and FIG. 1, when the amount of S is too small with respect to Cu, the color of the glass is blue, and when it is too large, the color is brown.
In FIG. 1, the Cu 2 O equivalent mol value / SO 3 equivalent mol value for obtaining a good red color (copper red) having a dominant wavelength (λd) of 593 to 625 nm is 1.50 to 0.70. Also, dominant wavelength (.lambda.d) better red Cu 2 O in terms mol value for a (Doaka) / SO 3 conversion mole value of 600~625nm is 1.45 to 0.78.
Therefore, a favorable copper red glass can be stably obtained by setting the ratio of the amount of Cu and S in this range.

その理由として、ガラスが赤色に発色する原因となる銅コロイドは、核となる物質の周りに金属銅が析出して成長すると考えられ、ガラス中のＣｕとＳの量の比が適度であれば、核となるＣｕＳやＦｅＳの量が適度となり、銅コロイドが順調に生成されて良好な赤色に発色するが、Ｃｕに対してＳの量が少なすぎると、核になる物質が少なくなって銅コロイドの生成が不十分となり、赤色が薄くなったり赤色に発色せずに青色となったりし、Ｃｕに対してＳの量が多すぎるとガラス中のＣｕＳの量が多くなりすぎ、茶色系の色となってしまうと考えられる。   The reason for this is that the copper colloid that causes the glass to develop a red color is thought to grow by depositing copper metal around the core material, and if the ratio of the amount of Cu and S in the glass is moderate The amount of CuS and FeS serving as nuclei becomes moderate, and copper colloids are generated smoothly and develop a good red color. However, if the amount of S relative to Cu is too small, the amount of nuclei becomes less and copper Colloid formation is insufficient, red color becomes thin or blue color does not develop red, and if the amount of S relative to Cu is too large, the amount of CuS in the glass becomes too large, It is thought that it becomes a color.

本発明の銅赤ガラスは、再加熱処理を行うことなく安定して銅赤色に発色するので、歩留まりよく製造することができる。また、使用する銅の量が少なくてよいので、従来よりも低コストとなる。   Since the copper red glass of the present invention stably develops a copper red color without reheating, it can be manufactured with a high yield. Moreover, since the amount of copper to be used may be small, the cost is lower than in the past.

表２のガラス組成となるように原料を調合し、１４５０℃の電気炉で１時間溶融し、攪拌を行った後に、さらに1時間溶融した。できたガラスは６００℃の徐冷炉に投入後、常温になるまで自然放冷を行って比較例及び、硫黄成分を芒硝で添加した実施例１、硫黄成分を硫化亜鉛で添加した実施例２のガラスを作成した。   The raw materials were prepared so as to have the glass composition of Table 2, melted in an electric furnace at 1450 ° C. for 1 hour, stirred, and further melted for 1 hour. The resulting glass was placed in a slow cooling furnace at 600 ° C. and then allowed to cool to room temperature, and then the glass of Comparative Example, Example 1 in which the sulfur component was added with sodium sulfate, and Example 2 in which the sulfur component was added with zinc sulfide. It was created.

比較例の光透過率曲線を図２に示す。
比較例は、Ｃｕ２Ｏ／ＳＯ３換算モル比が所定の範囲より大きく、ガラス中のＳの量がＣｕの量に対して不足しているため、核になる物質が少なくなって銅コロイドの生成が不十分となり赤色に発色しなかった。 The light transmittance curve of the comparative example is shown in FIG.
In the comparative example, the Cu 2 O / SO 3 conversion molar ratio is larger than the predetermined range, and the amount of S in the glass is insufficient with respect to the amount of Cu. Formation was insufficient and the color did not develop red.

実施例１の光透過率曲線を図３に、実施例２の透過率曲線を図４に示す。
実施例１、２は、共に、Ｃｕ２Ｏ／ＳＯ３換算モル比が所定の範囲であるので、良好な銅赤ガラスとなっている。 The light transmittance curve of Example 1 is shown in FIG. 3, and the transmittance curve of Example 2 is shown in FIG.
In both Examples 1 and 2, the Cu 2 O / SO 3 equivalent molar ratio is within a predetermined range, and therefore, it is a good copper red glass.

次に、ＣｕとＳの量、及びＣｕ２Ｏ換算モル値／ＳＯ３換算モル値をほぼ一定にし、Ｆｅの量を種々に変化させ、表３の実施例３〜１１及び表４の比較例２，３を作成した。なお、表３，４において、透過率、主波長及び刺激純度の換算厚みは２ｍｍである。
また、赤色の鮮やかさを表す指標としてレッドネスレシオを記載した。これは、２ｍｍ厚さにおける波長７００ｎｍの透過率と波長６００ｎｍの透過率の比（波長７００ｎｍの透過率／波長６００ｎｍの透過率）で、数値が大きいほど鮮やかな赤となり、良好な赤色は概ね５．０以上である。 Next, the amounts of Cu and S, and the molar value of Cu 2 O equivalent / SO 3 equivalent molar value were made substantially constant, and the amount of Fe was changed in various ways. Examples 3 to 11 in Table 3 and Comparative Examples in Table 4 2 and 3 were created. In Tables 3 and 4, the converted thickness of transmittance, dominant wavelength, and stimulus purity is 2 mm.
Moreover, the redness ratio was described as an index representing the vividness of red. This is the ratio of the transmittance at a wavelength of 700 nm to the transmittance at a wavelength of 600 nm (a transmittance at a wavelength of 700 nm / a transmittance at a wavelength of 600 nm) at a thickness of 2 mm. 0.0 or more.

実施例３〜１１は、いずれもＦｅの量、及びＦｅ２Ｏ３換算モル値／ＳＯ３換算モル値が適正であるため、好ましい赤色に発色した。
比較例２，３は、いずれもＦｅの量、及びＦｅ２Ｏ３換算モル値／ＳＯ３換算モル値が少なすぎるため、きわめて薄い赤色となった。 In Examples 3 to 11, since the amount of Fe and the Fe 2 O 3 equivalent molar value / SO 3 equivalent molar value were appropriate, the color was changed to a preferable red color.
In Comparative Examples 2 and 3, since the amount of Fe and the Fe 2 O 3 equivalent molar value / SO 3 equivalent molar value were too small, the color was extremely light red.

Ｆｅ２Ｏ３の量が多くなってもガラスは赤色を呈するが、多くなるにしたがって赤色領域の透過率が低くなり、暗い赤色になる。
FIG. 5 shows transmittance curves of Examples 6, 10, and 11 and Comparative Example 2.
