Abstract
Description
本発明は、工作用粘土組成物に関するものである。 The present invention relates to a clay composition for work.
従来の工作用粘土組成物（以下、単に「粘土組成物」とも言う）としては、種々の材質のものが知られている。例えば、土を主体にしたもの、紙（和紙）を主体としたもの、無機粉体としての炭酸カルシウム及びタルク、あるいはシラスバルーンを主体としたもの、小麦やとうもろこしを主体としたもの等が挙げられる（特開平９−２０２６５９号公報，特開平１１―２２４０４４号公報，特開２００１−１８３９７２号公報）。 As a conventional work clay composition (hereinafter, also simply referred to as “clay composition”), various materials are known. For example, those mainly composed of soil, those mainly composed of paper (Japanese paper), calcium carbonate and talc as inorganic powders, those mainly composed of shirasu balloon, those mainly composed of wheat and corn, etc. (Japanese Patent Laid-Open Nos. 9-202659, 11-224044, and 2001-183972).
これら粘土組成物は、それ自体は、茶色、グレー、白色等の色を有し、白色をベースに、赤、青などに着色されたものもある。
しかしながら、上記のような従来の粘土組成物にあっては、前述のような成分が主体となっていたため、着色が制限されて作品の自由度を損なうという問題があった。例えば、茶色やグレーの粘土組成物では、造形した作品に着色することすら困難である。また、白色の粘土組成物では、着色は可能であるが、発色が不十分であり、光沢も得られないという問題がある。一方、白色をベースに既に着色された粘土組成物は、色数が限定されている。 However, in the conventional clay composition as described above, since the above-described components are mainly used, there is a problem that coloring is restricted and the degree of freedom of the work is impaired. For example, with a brown or gray clay composition, it is difficult to even color the shaped work. In addition, although the white clay composition can be colored, there is a problem in that coloring is insufficient and gloss cannot be obtained. On the other hand, the number of colors of the clay composition already colored based on white is limited.
本発明は上記に鑑みてなされたものであり、従来の粘土組成物と比較して、着色性、発色性、光沢が優れた粘土組成物を提供することを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide a clay composition having excellent colorability, color developability, and gloss as compared with conventional clay compositions.

Two or more of these water-soluble substances may be used, and salts and alcohols may be used in combination.
これら（ｂ）成分の水溶性物質の配合量は、（ｃ）水との重量比で、水：水溶性物質＝１：９〜７：３の範囲であることが好ましく、２：８〜４：６であることがより好ましい。上記範囲より水が多いと水溶性高分子が溶解して、塑性を発現し難くなる傾向があり、水が少ないと水溶性高分子が十分に膨潤できず、透明性が得られ難くなる傾向がある。 The blending amount of the water-soluble substance of component (b) is preferably in the range of (c) water: water-soluble substance = 1: 9 to 7: 3 in a weight ratio of 2: 8 to 4 : 6 is more preferable. If the amount of water is larger than the above range, the water-soluble polymer tends to be dissolved, and the plasticity tends to be difficult to develop. is there.
