Title:
FLAME-RETARDANT VIBRATION-DAMPING RUBBER COMPOSITION AND FLAME-RETARDANT VIBRATION-DAMPING RUBBER MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/186025
Kind Code:
A1
Abstract:
This flame-retardant vibration-damping rubber composition comprises the following (A) to (D), the proportion of (B) being 20-150 parts by mass, the proportion of (C) being 0.01-5.0 parts by mass, and the proportion of (D) being 10-80 parts by mass with respect to 100 parts by mass of (A). This makes it possible to provide a flame-retardant vibration-damping rubber composition and a flame-retardant vibration-damping rubber member that are excellent in vibration-damping rubber properties such as rubber physical characteristics and dynamic magnification while maintaining flame-retardant property. (A) Diene rubber. (B) Metal hydroxide. (C) Dihydrazide compound. (D) Carbon black.
