実施例1に於いてシリコーンオイルを用いること無く作成した。
べたつき感がひどく、手に酷く付着するため、本発明の目的に適う「工作用粘土」と言い得るものではなかった。
(13) Comparative Example 1 (no calcium chloride)
In Example 1, it was prepared without using calcium chloride.
Even if it tried to knead, it became sticky and sticky, it was extremely difficult to knead, and I could not make what could be called clay for work.
(14) Comparative Example 2 (no adhesion suppression component)
It was prepared in Example 1 without using silicone oil.
Since the sticky feeling was so bad and it adhered to the hand severely, it could not be said to be a “working clay” suitable for the purpose of the present invention.

実施例1〜3、6、7より分かるように、骨材であるタルク12〜36質量%と、第1の糊剤であるCMC4〜12質量%と、第2の糊剤である塩化カルシウム9〜27質量%と、離型剤であるジメチルポリシロキサン0.1〜2質量%と、水40〜60質量%を、合計で100質量%となる配合としたとき、十分に良好な結果を得た。   As can be seen from Examples 1 to 3, 6 and 7, talc 12 to 36% by mass as aggregate, CMC 4 to 12% by mass as first paste, and calcium chloride 9 as second paste 9 When 27 wt%, 0.1-2 wt% of dimethylpolysiloxane, which is a mold release agent, and 40-60 wt% of water are combined in a total amount of 100 wt%, sufficiently good results are obtained. It was.

実施例1と実施例4から分かるように、シリコーンオイルを少なめとした場合は、手で持ったときに「若干のべたつき感」は生じたが、手に付着はしなかった。また、実施例1と実施例5から分かるように、シリコーンオイルを多めとした場合は、手で持ったとき軟化はしたが速やかではなく、手に付着はしなかったが、若干のべたつき感は生じた。
なお、実施例4と5の何れも、一応は、本発明の目的に適う程度であった。
As can be seen from Example 1 and Example 4, when the amount of silicone oil was small, a “slight stickiness” was produced when it was held by hand, but it did not adhere to the hand. In addition, as can be seen from Example 1 and Example 5, when the silicone oil was large, it softened when held by hand, but it was not quick and did not adhere to the hand, but some stickiness was occured.
Incidentally, both Examples 4 and 5 were only suitable for the purpose of the present invention.

実施例1と実施例8から分かるように、水を少なめとした場合は、造形性、伸展性、形状維持性に若干の問題は生じたが、一応は、本発明の目的に適う程度であった。

As can be seen from Example 1 and Example 8, when the amount of water was reduced, there were some problems in the formability, extensibility, and shape maintenance, but for the time being, it was only suitable for the purpose of the present invention. It was.
In addition, as can be seen from Example 1 and Example 9, when a large amount of water was used, when it was held by hand, it did not soften quickly and did not adhere to the hand, but some stickiness was generated. In addition, some problems occurred in extensibility. In either case, it was only suitable for the purpose of the present invention.

実施例1と実施例10から分かるように、CMCの粘度を低粘度とした場合は手に付着はしないが若干のべたつき感は生じた。また、造形性、形状維持性にも若干の問題が生じた。また、実施例1と実施例11から分かるように、CMCの粘度を高粘度とした場合は手に付着はしないが若干のべたつき感は生じた。また、造形性、伸展性にも若干の問題が生じた。なお、実施例10と11の何れも、一応は、本発明の目的に適う程度であった。   As can be seen from Example 1 and Example 10, when the viscosity of CMC was low, it did not adhere to the hand, but some stickiness was generated. In addition, some problems were caused in the formability and shape maintenance. Further, as can be seen from Example 1 and Example 11, when the viscosity of CMC was high, it did not adhere to the hand, but some stickiness was generated. There were also some problems with formability and extensibility. In addition, both Examples 10 and 11 were suitable for the purpose of the present invention.

また、実施例1と実施例12から分かるように、シリコーンオイルの動粘度を高粘度とした場合、若干のべたつき感は生じたが、手に付着はせず、一応は、本発明の目的に適う程度であった。   Further, as can be seen from Example 1 and Example 12, when the kinematic viscosity of the silicone oil was set to a high viscosity, a slight stickiness was produced, but it did not adhere to the hand, and for the purpose of the present invention. It was suitable.

比較例1から分かるように、塩化カルシウムを欠いた場合、実施例と比較するまでもなく、そもそも、工作用粘土と言い得るものを作成することはできなかった。
また、比較例2から分かるように、シリコーンオイルを欠いた場合、粘土は作成できたが、本発明の目的に適う工作用粘土と言い得るものではなかった。
As can be seen from Comparative Example 1, when calcium chloride was lacking, it was not possible to make what could be called clay for work in the first place, without comparing with Example.
Further, as can be seen from Comparative Example 2, when silicone oil was absent, clay could be prepared, but it could not be said to be a work clay suitable for the purpose of the present invention.
