A silicone rubber composition is provided. The composition comprises: (A) a straight chain organopolysiloxane having at least two alkenyl groups in a molecule; (B) a resinous organopolysiloxane containing: SiO4/2 unit, R12R2SiO1/2 unit and R13SiO1/2 unit, wherein R1 independently represents an alkyl group having 1 to 12 carbon atoms and R2 represents an alkenyl group having 2 to 12 carbon atoms, and containing 0.1 to 5.0 mass % of the alkenyl groups; (C) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule; (D) a hydrosilylation reaction catalyst; (E) a reinforcing silica fine powder; and (F) an intumescent flame retardant. When the composition is coated on a woven material, such as a base material for an airbag or the like, the composition can provide the woven material with sufficient flame retardance even with a low coating amount, and the composition can suppress an aperture of the woven material.
