(57) [Summary] (Amended) (Solution) (A) Organopolysiloxane having two or more alkenyl groups bonded to silicon atoms in one molecule, (B) Reinforcing silica filler, (C) In continuously producing a liquid silicone rubber base by mixing a mixing aid represented by the general formula (1) or (2), With respect to 100 parts of the component (B), the components (A) 10-1 After preparing a premixed liquid by mixing 20 parts with 1 to 35 parts of component (C), 100 parts of component (B) and premixed liquid are mixed to produce a premixed powder. Kneading the component (A) in a proportion of at least 20 parts with respect to 100 parts of the body to produce a liquid silicone rubber base, and then adding (E) an organohydrogenpolysiloxane and (F) a platinum catalyst. A method for producing a high fatigue-durable liquid silicone rubber composition, comprising: [Effect] In particular, a cured product excellent in durability fatigue resistance is provided, and a liquid silicone rubber composition excellent in viscosity stability during storage can be obtained. |
