Description
【発明の詳細な説明】 （産業上の利用分野） 本発明はリン酸塩系ガラス組成物、特に低融点で無色
乃至は無色に近い色彩を有するガラスフリットに係るも
のである。TECHNICAL FIELD The present invention relates to a phosphate glass composition, and more particularly to a glass frit having a low melting point and a colorless or nearly colorless color.
（従来の技術） 従来、ガラスフリット素材としては、長石系が一般に
用いられているが、これは焼付温度が1000℃以上と高い
為、耐熱性の高い基材にしか適用出来ない。又、より低
温で焼付出来るフリットとして鉛を含有するフリット材
が知られているが、製造作業者や製品使用者への毒性が
懸念されている。(Prior Art) Conventionally, as a glass frit material, a feldspar-based material is generally used, but since this has a high baking temperature of 1000 ° C. or higher, it can be applied only to a base material having high heat resistance. Further, a frit material containing lead is known as a frit that can be baked at a lower temperature, but it is feared that the frit material will be toxic to manufacturing operators and product users.
他方、リン酸塩系ガラスは一般に低温で溶融し、しか
も粘性が低いことから低温用フリットとして期待される
が、この系のガラスは一般に化学的安定性、特に耐水性
に乏しい欠点を有している。On the other hand, phosphate-based glass is generally expected to be a low-temperature frit because it melts at low temperature and has low viscosity, but this type of glass generally has the drawback of poor chemical stability, especially poor water resistance. There is.
この様なガラスに対し、アルミナ等の添加物を用いて
耐水性を向上せしめたリン酸塩系ガラスもいくつか提案
されている。In addition to these glasses, some phosphate-based glasses have been proposed in which the water resistance is improved by using an additive such as alumina.
（発明の解決しようとする問題点） しかしながら、この様に耐水性を向上せしめたリン酸
塩系ガラスにあっては、一般にこれを焼付けた場合、灰
色に着色しやすい欠点を有し、その応用例として該フリ
ットを歯科用のステイン剤の如き材料に用いる場合に
は、その着色により不都合が生じる欠点を有している。(Problems to be Solved by the Invention) However, a phosphate glass having improved water resistance as described above generally has a drawback that when it is baked, it tends to be colored gray, and its application For example, when the frit is used for a material such as a dental stain agent, it has a drawback that its coloring causes an inconvenience.
（問題点を解決する為の手段） 本発明者は、この様なリン酸塩系ガラスの灰色着色を
防止し、無色乃至はそれに近い色彩を呈し得るガラス組
成物を見出すことを目的として種々研究、検討した結
果、リン酸塩系ガラス中に特定の金属酸化物を含有せし
めることにより前記目的を達成し得ることを見出した。(Means for Solving Problems) The present inventor conducted various studies for the purpose of finding a glass composition capable of preventing such a gray coloring of a phosphate-based glass and exhibiting a colorless color or a color close thereto. As a result of the investigation, it was found that the above object can be achieved by incorporating a specific metal oxide into the phosphate glass.
かくして本発明は、リン酸塩系ガラスフリット粉末
と、熱処理により酸素を発生する金属の酸化物とを含有
したリン酸塩系ガラス組成物を提供するにある。Thus, the present invention is to provide a phosphate glass composition containing a phosphate glass frit powder and an oxide of a metal that generates oxygen by heat treatment.
本発明において用いられる熱処理により酸素を発生す
る金属の酸化物としては、リン酸塩系ガラスフリットを
焼付ける際に酸素を発生し、この為に灰分として残る金
属酸化物と共に無色化し得るものであればよく、例えば
CeO2,Fe2O3,TiO2,Sb2O5,SnO2,MnO2,CrO3,KMnO4,K2Cr2O7
等が挙げられる。The metal oxide that generates oxygen by heat treatment used in the present invention may be one that generates oxygen when baking a phosphate glass frit and can be colorless together with the metal oxide that remains as ash. Ok, for example
CeO 2 , Fe 2 O 3 , TiO 2 , Sb 2 O 5 , SnO 2 , MnO 2 , CrO 3 , KMnO 4 , K 2 Cr 2 O 7
Etc.
これら金属酸化物の使用量は、厳密にはリン酸塩系ガ
ラスフリットの組成等により決定されるが、一般に0.01
〜10重量％程度を採用するのが適当である。使用量が前
記範囲に満たない場合には、灰色の着色を有効に防止出
来ず、逆に前記範囲を超える場合には、上記金属酸化物
がガラスフリットの熱処理による融着を阻害する虞れが
あるので何れも好ましくない。The amount of these metal oxides used is strictly determined by the composition of the phosphate glass frit, etc.
It is suitable to employ about 10% by weight. When the amount used is less than the above range, gray coloring cannot be effectively prevented, and when the amount exceeds the above range, the metal oxide may hinder the fusion of the glass frit due to the heat treatment. None of them are preferable because they exist.
そしてこれら範囲のうち、前記表示に従い、0.1〜５
重量％を採用すると灰色の着色を効果的に防止し、しか
もその他の不都合も実質的に生じないので特に好まし
い。And, within these ranges, 0.1 to 5 according to the above display
The use of the weight% is particularly preferable because it effectively prevents gray coloring and causes substantially no other inconvenience.
次に本発明に用いられるリン酸塩系ガラスフリットと
しては、リン酸分をP2O5として40〜85モル％含有してい
るものが好ましい。リン酸分が前記範囲に満たない場合
にはガラスフリットの焼成時に結晶化を起こし易く平滑
な被膜が形成できず逆に前記範囲を超える場合にはガラ
スフリットの耐水性が十分でなくなったり、焼成温度が
高くなりすぎる虞れがあるので何れも好ましくない。そ
してこれら範囲のうち、P2O5として60〜75モル％を採用
する場合には、光沢に富み、平滑な耐水性に富む被膜
が、低温て形成できるので特に好ましい。Next, as the phosphate glass frit used in the present invention, those containing 40 to 85 mol% of phosphoric acid as P 2 O 5 are preferable. If the phosphoric acid content is less than the above range, crystallization tends to occur during firing of the glass frit and a smooth coating cannot be formed. On the contrary, if it exceeds the above range, the water resistance of the glass frit becomes insufficient, or firing is performed. Both are not preferable because the temperature may be too high. And, when 60 to 75 mol% of P 2 O 5 is adopted within these ranges, it is particularly preferable because a film having a high gloss and a smooth water resistance can be formed at a low temperature.
実際この様なフリットの組成としては、CaO1〜35モル
％,Al2O310〜25モル％,P2O540〜85モル％を採用するの
が好ましい。In fact, as the composition of such a frit, it is preferable to employ CaO 1 to 35 mol%, Al 2 O 3 10 to 25 mol%, and P 2 O 5 40 to 85 mol%.
この様な組成を採用すると高い耐水性と低融点を有
し、フリットとして好ましい性質を有している。When such a composition is adopted, it has high water resistance and a low melting point, and has favorable properties as a frit.
本発明においては、フリット中にこれら成分の他に本
発明の目的を逸脱しない限り他の成分を添加することが
