Document Type and Number:
WIPO Patent Application WO/2024/004854
Kind Code:
A1
Abstract:
Provided are an anti-vibration rubber composition and an anti-vibration rubber member, which can suppress a decrease in durability while improving resistance to vulcanization reversion. The anti-vibration rubber composition contains components (A) to (E), and is characterized in that relative to 100 parts by mass of component (A), the content of component (B) is 0.6-5.5 parts by mass, the content of component (C) is 0.45-3.5 parts by mass, the content of component (D) is 0.25-5.5 parts by mass, and the mass ratio [(C)/(D)] of component (C) relative to component (D) is 0.15-5.0. (A) A diene-based rubber. (B) A bismaleimide compound. (C) A sulfenamide-based vulcanization accelerator. (D) A sulfur-based vulcanizing agent. (E) An inorganic filler.
