JPH1020767A - Craft clay insoluble in water - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily manufacture the clay free from dissolution and deformation even when it is placed in the open air, and is wetted by rain and water, by mixing carboxymethyl cellulose which becomes insoluble after dried, with powder of every kind. SOLUTION: Carboxymethyl cellulose which becomes insoluble after dried, is added to a mixture of the pulp powder, stone dust, inorganic foam, organic foam or the like, and is kneaded. The powder of every kind is wrapped up in the carboxymethyl cellulose, and is dried, so that the melting of the clay can be prevented when it is wetted by rain and water. The intended clay can be obtained by kneading, for example, 5 part of pulp powder, 50 part of inorganic powder, 20 part of inorganic foam, 10 part of organic pawder, 10 part of carboxymethyl cellulose which becomes insoluble after dried, and a proper quantity of water. The melting of a work can not be found, when the submerging test of the work is performed for example, for 7 days, after the work is made out of the clay, and sufficiently dried. Thereby it becomes possible to make the work for the outdoor display or the work using the water (a fountain or the like), by using the clay.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to clay used as a sculpture teaching material in school teaching materials and as a handicraft material in social education.

[0002]

2. Description of the Related Art Clays in the above-mentioned field include clays prepared by mixing a water-soluble chemical paste (such as metroze, carboxymethylcellulose, and poval) with various powders.

[0003]

Considering the conventional method of placing clay outdoors, it has been practiced to apply a water-resistant paint after baking or drying. The baking method was time-consuming and was easily damaged during the operation, and it was difficult to apply the paint completely without gaps, and water entered through the gaps and ruined the work. SUMMARY OF THE INVENTION An object of the present invention is to provide a clay which can be easily formed and which does not dissolve or deform even when exposed to rain or water by being insolubilized after drying.

[0004]

In order to achieve the above object, carboxymethyl cellulose which is insolubilized after drying is
Mix with various powders.

[0005]

Since the carboxymethyl cellulose wraps and dries various powders, the clay does not melt even if it is exposed to rain or water.

[0006]

Considering the above, 5 parts of pulp powder / 5 inorganic powder
0 parts / 20 parts of inorganic foam / 10 parts of organic powder / 10 parts of carboxymethyl cellulose to be insolubilized after drying / appropriate amount of water were mixed to obtain the clay intended for the present invention.

[0007]

After making a work with the above clay and drying it sufficiently, a immersion test was carried out in water for 7 days, but it did not melt out. The water resistance of the finished product after drying is unprecedented, making it possible to exhibit works outdoors and produce works that use water (for example, fountains).
