Document Type and Number:
WIPO Patent Application WO/2015/072617
Kind Code:
A1
Abstract:
The present invention relates to rubber clay for crafts capable of changing colors according to the temperature, and the objective thereof is to provide rubber clay which is reusable since the rubber clay containing, as a main ingredient, an inorganic compound with an appropriate degree of plasticity is neither sticky so as to not stick to hands nor does the clay hardened even though a crafted product (a model) is manufactured therewith and left out, and of which the colors thereof change according to temperature changes to more effectively encourage curiosity and creativity. The rubber clay for crafts capable of changing colors according to the temperature, according to the present invention, comprises: (1) a gel-state silicon base provided in the amount of 60% to 80% on the basis of the total weight of the rubber clay and is produced by mixing siloxane, silicon, dimethyl, methylvinyl, and vinyl group-terminated;(2) a plasticity adjusting agent for adjusting hardness, which is provided in the amount of 15% to 30% on the basis of the total weight of the rubber clay and includes powder-type silica; (3) an oil-type anticaking agent for preventing solidification, which is provided in the amount of 1% to 5% on the basis of the total weight of the rubber clay and includes polydimethylsiloxane; (4) a color pigment provided in the amount of 1% to 3% on the basis of the total weight of the rubber clay and producing colors; and (5) a thermochromic pigment provided in the amount of 0.01% to 3% on the basis of the total weight of the rubber clay and changing colors according to temperature changes.
