And P-2 must be a mixture. 25 ° C for P-1
The organopolysiloxane has a viscosity in the range of 5000 cSt to 200,000 cSt, and P-2 has a viscosity at 25 ° C of 1 million cSt or more and is substantially a raw rubber-like organopolysiloxane.

When the amount of low-viscosity P-1 is large, the obtained rubber clay composition easily flows and is easily deformed after modeling work. The rubber clay composition obtained with a large amount of P-2 has a poor viscosity and is messy. Further, if the viscosity of P-1 is lower than 5000 cSt, the rubber-clay composition tends to flow or bleed easily.

˜50 μ, and preferably 0.5 to 30 μ. If the average particle size is less than 0.1 μm, the rubber clay composition becomes too hard or the viscosity becomes poor when a predetermined amount is filled. Further, if the average particle size exceeds 50 μ, it is difficult to obtain a rubber clay composition having elongation. Further, the compounding amount is preferably 20 to 80 parts by weight with respect to 100 parts by weight of the component (A). If it is too small, it is difficult to obtain a preferable clay-like product, and if it is too large, the rubber clay composition becomes too hard, and the necessary blending amount of the component (C) increases in order to obtain a rubber clay composition that floats in water with a specific gravity of 1.0 or less. However, it is difficult to obtain a preferable clay-like material.

げられる。 (C) The glass balloon (C) component has a specific gravity of 1.0 which floats the rubber clay composition of the present invention in water.
It is a hollow glass balloon, which is an essential component for the following. The particle diameter of the glass balloon must be 200 μm or less, preferably 150 μm or less, in order to obtain a rubber clay having a good feel. The smaller the average density of glass balloon particles (hereinafter referred to as the average particle density), the more advantageous it is to obtain a silicone rubber clay composition having a specific gravity of 1.0 or less, but the pressure resistance of the balloon decreases, and the obtained rubber clay composition is used as a machine. The glass balloon is easily broken during mixing and kneading. Generally, when the average particle density is less than 0.2 g / cc, the pressure resistance is 30 kg / cm 3 or less, and the strength is too low. Further, when the average particle density exceeds 0.8 g / cc, the pressure resistance of the glass balloon becomes 700 kg / cm 3 or more, so that the balloon is not broken when mechanically kneading the obtained clay composition, but the clay composition is If the specific gravity is 1.0 or less, the required amount of the compound is increased, which is not preferable. From the above, the average particle density is preferably 0.2 g / cc to 0.8 g / cc, preferably
It is 0.3g / cc to 0.6g / cc. Commercially available glass balloons that meet such conditions include trade names: CEL-STAR (glass balloon) [Asahi Glass Co., Ltd.], glass bubbles [3M Company], and the like.

The liquid paraffin is preferably 10 parts by weight or less with respect to 100 parts by weight of the component (A).
If it exceeds 10 parts by weight, the liquid paraffin bleeds onto the surface of the clay composition and adheres to the hands, or the clay floats on the water surface when the water is floated. In addition, if necessary, for example, a small amount of fumed silica, wet silica, or an organic or inorganic pigment for coloring in various colors may be added to the clay composition of the present invention.
