「実施例」 以下、図面を参照し、本発明の詳細な説明する。"Example" Hereinafter, the present invention will be described in detail with reference to the drawings.
まず、本実施例においては、金属物品の材料として、
貴金属粉末：５０〜９０重量％、
セルローズ系水溶性バインダー二０８〜８重量％、界面
活性剤・０．０３〜３重量％、
油脂二〇、１〜３重量％、
を含有し、残りが水および不可避不純物からなる造影用
可塑性組成物を使用する。金属物品の製造方法の説明に
先立ち、この造影用可塑性組成物の製造手順について説
明する。First, in this example, the materials for the metal article are: noble metal powder: 50-90% by weight, cellulose-based water-soluble binder 208-8% by weight, surfactant 0.03-3% by weight, oil and fat 20% by weight. , 1 to 3% by weight, with the remainder consisting of water and unavoidable impurities. Prior to explaining the method for producing the metal article, the procedure for producing this contrast-enhancing plastic composition will be explained.
まず、セルローズ系水溶性バインダーと水とを混合し、
暫く放置して寒天状物質とする。次いて、この寒天状物
質に界面活性剤を添加して混合し、さらに所望の貴金属
粉末を添加して混合する。そして、この貴金属粉末混合
体に油脂を添加１７て混合することにより、合金金粘土
が製造される。First, a cellulose-based water-soluble binder and water are mixed,
Leave it for a while to form an agar-like substance. Next, a surfactant is added to this agar-like material and mixed, and a desired noble metal powder is further added and mixed. Then, a gold alloy clay is manufactured by adding oil and fat to this noble metal powder mixture 17 and mixing the mixture.
次に造形用可塑性組成物の組成を上記のように決めた理
由を説明する。Next, the reason why the composition of the plastic composition for modeling was determined as described above will be explained.
（ｓ）貴金属粉末
金、銀、銅、白金、およびそれらの合金等の貴金属粉末
は、造形用可塑性組成物を構成する主成分であり、製品
の色を決定する重要な要素であるが、その含有量が５０
重置火未満ではその効果がなく、一方、９０重重量以上

びおよび強度が低下するようになるので好ましくない。(s) Precious metal powder Precious metal powders such as gold, silver, copper, platinum, and their alloys are the main components of plastic modeling compositions and are important elements that determine the color of products. Content is 50
If the content is less than 90% by weight, there is no effect, whereas if the content exceeds 90% by weight, the elongation and strength of the resulting plastic composition for modeling will decrease, which is not preferable.
従って、上記の通り、貴金属粉末の含有量は、５０〜９
０重購％とした。Therefore, as mentioned above, the content of noble metal powder is 50 to 9
It was set as 0 double purchase%.
また、添加する貴金属粉末の平均粒径は、２００１１−
を絨えると貴金属造影用可塑性組成物の伸びお上び強度
が低下することから２００μ−以下とすることが好まし
い。In addition, the average particle size of the noble metal powder to be added is 20011-
If it is thickened, the elastic composition for contrast imaging with noble metals will elongate and its strength will decrease, so it is preferably 200 μm or less.
（ｂ）セルローズ系水溶性バインダー
セルローズ系水溶性バインダーは、加熱すると速やかに
ゲル化して固化し、造形物の影状の保持を容易にする。(b) Cellulose-based water-soluble binder When heated, the cellulose-based water-soluble binder quickly gels and solidifies, making it easier to maintain the shape of a shaped object.
しかし、その添加量がＯ，２重量％未満ではその効果が
得られず、一方、８重職％より多く添加すると活性度が
大きくなり過ぎて造形することができなくなってしまう
。従って、上記の通り、セル口、−ズ系水溶性バインダ
ーの含有量は、０．８〜８重量％とした。セルローズ系
水溶性バインダーとしては、メチルセルローズ、エチル
セルローズ等が好ましい。However, if the amount added is less than 2% by weight of O, the effect cannot be obtained, while if it is added more than 8% by weight, the activity becomes too high and it becomes impossible to form. Therefore, as described above, the content of the water-soluble binder in the cell opening was set to 0.8 to 8% by weight. As the cellulose-based water-soluble binder, methylcellulose, ethylcellulose, etc. are preferable.

ない。従って、上記の通り、界面活性剤の添加量は０，
０３〜３重量％とじた。(e) FF, ffi activator By adding and mixing the surfactant, the solid particles produced by the reaction between the binder and water are crushed, and the precious metal powder and the binder are mixed together. The effect of improving the mixability can be obtained. However, if the amount of surfactant added is less than 0.03% by weight, the effect is not sufficient, whereas if the amount of surfactant added is more than 3% by weight, the resulting plastic 'MX composition for noble metal contrast imaging This is not preferable because the degree of acidity decreases and fluidity increases, making it impossible to perform contrast imaging. Therefore, as mentioned above, the amount of surfactant added is 0,
03 to 3% by weight.
（ｄ）油脂

って、上記の通り、油脂の含有量は０．１〜３重飛％と
じた。(d) Fats By adding a small amount of fats and oils, it is possible to prevent the plastic composition for true metal modeling from adhering to hands during modeling. However, if the amount added is less than 0.1% by weight, the effect cannot be obtained; on the other hand, if it is added more than 3111% (by weight), the plastic composition for precious metal modeling becomes oily and slippery, and This is not preferable because it impairs workability.Therefore, as mentioned above, the content of oil and fat is limited to 0.1 to 3%.

Next, as shown in FIG. 1 (B), the plastic composition for modeling containing pure gold powder obtained by the method described above is spread thinly by hand on the surface of the leaf L, and shaped into the outer shape of the leaf L using a bamboo spatula or the like. Unnecessary plastic composition is removed along the line to create a molded body 2 having the same shape as the leaf I. Then, as shown in FIG. 1(c), this molded body 2 is placed in an electric furnace 3 and heated in air at 1000° C. to undergo solid phase sintering. Regarding the sintering conditions in the electric furnace 3, in the case of a plastic composition containing pure gold, it is sufficient to heat it in air at 1000°C.
In the case of a plastic composition containing alloy metals of so-called K]8 mixed in a ratio of wtL 12 , 5 vtL = 12 , 5 vt%, in argon gas 800
Just heat it at ℃. In this sintering process, Konoha 1
Most of it is lost through combustion. Although a slight ashy residue is produced, this residue can be easily removed. As a result, the desired metal article 4 having the fine vein pattern on the surface of the leaf l as shown in FIG. 1(d) is completed.
