本発明は金属処理剤に関し、特に歯科用金属の表面にお
ける酸化被膜に対して、優れた剥離ないし溶解性を有し
、審美性の金属光沢を再生する金属処理剤に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a metal treatment agent, and in particular to a metal treatment agent that has excellent peeling or solubility properties for oxidized films on the surface of dental metals, and is an aesthetic metal treatment agent. This invention relates to a metal processing agent that reproduces luster.

ラウン、ブリッヂなどに用いられる例えば金、銀、パラ
ジウム合金などの金植は、鋳造において高温にさらされ
るために、その表面に酸化被膜を生成して黒く変色する
。In general, repair missing teeth! Gold, silver, and palladium alloys, which are used for inlays, crowns, bridges, etc., are exposed to high temperatures during casting, so they form an oxide film on their surfaces and turn black.
このような酸化被膜は、金属の表面に強ｌＩ４にくっつ

的に除去することか鍮かしく、一般に酸などの溶液に浸
αｌして溶解、除去される。Since such an oxide film strongly adheres to the surface of the metal, it is difficult to remove it mechanically without damaging the surface of the metal, but it is generally dissolved by soaking it in a solution such as an acid. , removed.
従来、一般に金属の酸化被膜を除去する処理剤としては

を溶解してしまう問題もある。他方、有機酸も使用され
るが、一般に作用が弱いために、幣化仮膜の除去を短時
間で充分に應成することか困難である。Conventionally, inorganic acids such as hydrochloric acid and sulfuric acid, for example, have been used as processing agents for removing metal oxide films. However, these are hazardous substances and pose operational hazards such as heat generation during dilution, generation of harmful gases during heating, and scattering during immersion and removal, and careful attention must be paid to the disposal of waste liquid after use. . Furthermore, depending on the metal being processed,
There is also the problem that there is a tendency to cause hydrogen embrittlement or that the acid action is too strong and dissolves the metal itself. On the other hand, organic acids are also used, but their effects are generally weak, and it is therefore difficult to remove the pseudofilm in a short period of time.

ている。To solve the above-mentioned problems, handling can be improved by mixing various acid components or adding other components to the acid component.
Treatment agents have been proposed that control the bathing effect on metals or oxide films. For example, Palm J Koan 56-29752 contains sulfamine, an alkali metal chloride, which is used as a surface treatment agent for plating work to remove the nitride film to prevent poor adhesion of the plating film and the occurrence of stains. A metal activator containing an acid is provided.

かつ厳密な調整が求められる。However, such a metal activator is a metal treatment agent used in plating work, and is used as a metal treatment agent for dentistry because it easily removes the oxide film and has good metallic luster. In order to maintain beauty, more relaxed and strict adjustments are required.
本発明者らは、歯科用金属の処理剤として上記した所望

ある歯科用金属の処理剤である。The present inventors have conducted extensive research into a metal treatment agent that achieves the above-mentioned desired objective as a treatment agent for dental metals, and as a result, have come up with the proposal of ``Midwa J''. be. That is, the present invention contains 0.01 to 1.5 moles of alkaline earth metal chloride to 2 to 71 moles of sulfamide,
The present invention is a treatment agent for dental metals in which the concentration of sulfamic acid is 0.05 to 2 mol/l.

アルカリ土類全編の塩化物としては、特に制限されない
が、一般に塩化マグネシウム、塩化カルシウムなどが好
適である。Since the metal treating agent of the present invention contains sulfamic acid as an acid component, it is easier to handle than an acid-free agent, and due to the combination of the sulfamic acid and an alkaline earth metal chloride, the oxide ( It has the effect of effectively and easily peeling off, dissolving, and removing broken membranes. The alkaline earth chloride used in the present invention is not particularly limited, but magnesium chloride, calcium chloride, etc. are generally preferred.

。Therefore, in the metal treating agent of the present invention, 0.00% of alkaline earth metal chloride is added to 91 moles of sulfamiscif.
The gold Fu to be treated can be used in a range of 01 to 15 mol.
It is extremely important to remove gold-N arsenide (coating) well without damaging the table mI. That is, the amount of alkaline earth gold screw/monide is 0.00% per mole of sulfamic acid.
If the treatment agent is less than 0.01, not only the removal of the gold-containing tympanic membrane is insufficient, but also the color changes to a coppery red color, which is undesirable. In addition, sulfamic acid 1
When the amount of alkaline earth metal chloride is more than 1.5 moles per mole, the removal of the gold Mm coating 11ζ2 is achieved, but the metal surface becomes brown in 11 colors, which is poor. .

This is extremely important for successfully removing the oxide film. ) 51 First, if the 6 degree of sulfamic acid is less than 0.05 mol/l, sufficient removal of the metal oxide film will not be achieved, and conversely, if it is greater than 1.5 mol/l, metal oxidation will occur. Although removal of the tympanic membrane is satisfactorily achieved, the metal surface becomes discolored to a coppery color, which is undesirable. In addition to sulfamine and alkaline earth metal chlorides, the treatment agent of the present invention contains, for example, a surfactant, etc., to the extent that the surface of the metal is not damaged, in order to improve the treatment effect on the metal. Other ingredients may be added.
本発明の処理剤は、その水溶液に歯科用金属を一般に浸
