METHOD FOR PRODUCING SILICONE RUBBER, AQUEOUS EMULSION FOR SILICONE RUBBER AND METHOD FOR PRODUCING SAME

摘要

A method of manufacturing a silicone rubber comprising: a first stage that comprises (1-1) the step of preparing an aqueous dispersion composed of water that contains an water-soluble polymer (E), a finely powdered silica filler (B), a conductive filler (C), and a non-conductive inorganic filler (D) and (1-2) the step of preparing an aqueous emulsion by stirring and mixing the obtained aqueous dispersion with the following components: an organopolysiloxane (A) that contains silicon-bonded alkenyl groups, an emulsification agent (F), and a curing agent (G); and (2-1) a second stage for obtaining a silicone rubber either by curing the aqueous emulsion prepared in the aforementioned first stage, forming a wet silicone-rubber like cured body, and then removing water from the aforementioned wet silicone-rubber like cured body; or (2-2) by dehydrating and curing the aqueous emulsion prepared in the aforementioned first stage; the aforementioned aqueous dispersion, and a method of preparation of the dispersion from components (A), (F), and (G).
