Title:
SILICONE RUBBER COMPOSITION AND WOVEN MATERIAL COATED WITH SILICONE RUBBER
Document Type and Number:
WIPO Patent Application WO/2021/221064
Kind Code:
A1
Abstract:
The present invention relates to a silicone rubber composition comprising: (A) a straight chain organopolysiloxane having at least two alkenyl groups in a molecule; (B) a resinous organopolysiloxane containing: SiO4/2 unit, R1
2R2SiO1/2 unit and R1
3SiO1/2 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 present composition is coated on a woven material such as a base material for an airbag or the like, it can provide the woven with sufficient flame retardance even with a low coating amount, and it can suppress an aperture of the woven.
