Abstract:
A method for producing a molded silicone rubber product comprising(i) forming a mixture comprising (A) a primary composition in the form of a paste comprising an inorganic filler and a diorganopolysiloxane containing at least 2 silicon atom-bonded alkenyl groups per molecule, (B) a liquid catalyst composition comprising a platinum catalyst and an organopolysiloxane containing at least 2 silicon atom-bonded alkenyl groups per molecule, and (C) a liquid curing composition comprising an organopolysiloxane having at least 2 silicon atom-bonded hydrogen atoms per molecule and an organopolysiloxane having at least 2 silicon atom-bonded alkenyl groups per molecule; (ii) feeding the mixture comprising components (A), (B), and (C) into a molding device; and (iii) curing the mixture comprising components (A), (B), and (C) by heating; wherein components (A), (B), and (C) are separately stored in a primary composition storage tank, catalyst composition storage tank, and curing agent composition storage tank, respectively; components (A), (B), and (C) are mixed by being fed to a mixing device connected to the storage tanks so as to produce a silicone rubber-forming composition; and the composition is then fed into a silicone rubber-forming device, where it is heated and cured.
