The present invention relates to rubber clay for handicrafts discolored depending on the temperature. The purpose of the present invention is to make the optimal plasticity of the rubber clay by using an inorganic compound as a main component. Accordingly, the rubber clay is free from stickiness, thereby not sticking to the hand of a user, and the rubber clay does not harden even when made into a handicraft (model) and unkept, thereby being reusable. Also, the color of the rubber clay changes depending on the temperature, thereby more effectively arousing curiosity, originality and creativity. According to the present invention, the rubber clay for handicrafts discolored depending on the temperature is formed by mixing: a silicone base (1) in a gel state, prepared in a content of 60-80% with respect to the total weight of the rubber clay and composed of a mixture of siloxane, silicone, dimethyl, methylvinyl, and vinyl group-terminated; a plasticity control agent (2) prepared in a content of 15-30% with respect to the total weight of the rubber clay and composed of a powder-type silica-based component to control hardness; an oil-type anti-solidifying agent (3) prepared in a content of 1-5% with respect to the total weight of the rubber clay and composed of a polydimethylsiloxane-based component to prevent solidification; a color pigment (4) prepared in a content of 1-3% with respect to the total weight of the rubber clay to create color; and a thermochromic pigment (5) prepared in a content of 0.01-3% with respect to the total weight of the rubber clay and discolored depending on the temperature change. |
