SILICONE RUBBER COMPOSITION |
摘要 |
The present invention relates to a silicone rubber composition comprising: (A) 100 parts by mass of an organopolysiloxane that has a degree of polymerization of 100 or more and contains at least two alkenyl groups each bound to a silicon atom in the molecule; (B) 10 to 100 parts by mass of a reinforcing silica having a specific surface area (BET method) of 50 m 2 /g or more; (C) 1 to 100 parts by mass of calcined mica having an average particle diameter of 20 µm or less; and (D) an effective amount of a curing agent. According to the present invention, even when a silicone rubber molded article is exposed to flame for a long time, ash of the silicone rubber molded article after firing is sintered (is transformed into a ceramic material) and the shape of the silicone rubber molded article before the firing (sintering) can be maintained. In addition, the rolling properties (workability) in a kneading step in the production of the silicone rubber composition is excellent. |
