Document Type and Number:
Japanese Patent JP6355108
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a silicone rubber composition having storage elastic modulus of a cured article which becomes low when strain rate is low and becomes high when the strain rate is high.SOLUTION: There is provided a silicone rubber composition containing spherical oxide fine particles with an average particle diameter of 0.05-30 μm, organopolysiloxane having a repeating unit represented by the average composition formula:RSiO (1) and at least one silicon atom-binding alkenyl group in a molecule and organohydrogenpolysiloxane having a repeating unit represented by average composition formula:RSiO (2) and at least two silicon atom-binding hydrogen atoms in a molecule, and having volume fraction Vof the spherical oxide fine particles to the total volume of a cured article of the composition satisfying a condition represented by the following formula (3):11×log(D)+9≤V≤15×log(D)+16 (3), where Dis an average particle diameter of the spherical oxide fine particles.SELECTED DRAWING: None
