The present invention provides an emulsion composition for a silicone rubber sponge for obtaining a silicone rubber sponge having uniform and fine cells and good dimensional accuracy, and a method for producing the sponge using the same. (A) (a) a diorganopolysiloxane having at least two alkenyl groups in one molecule, (b) an organopolysiloxane having at least two silicon-bonded hydrogens in one molecule, and (c) (A) an addition reaction curable liquid silicone rubber composition containing a platinum-based catalyst, (B) water containing a water-soluble polymer, and (C) an emulsifier, and (a), (b) and ( c) a total amount of 100 parts by weight, (B) 50 to 250 parts by weight, (C) an emulsion composition for a silicone rubber sponge containing 0.1 to 10 parts by weight, and dehydration after curing. Manufacturing method of silicone rubber sponge. [Selection figure] None |
