Title:
VIBRATION-PROOF RUBBER COMPOSITION AND VIBRATION-PROOF RUBBER MEMBER
Document Type and Number:
Japanese Patent JP2023096768
Kind Code:
A
Abstract:
To provide a vibration-proof rubber composition and a vibration-proof rubber member which are excellent in durability, can achieve a low dynamic-to-static modulus ratio, and can exhibit excellent scorch resistance under a wet heat environment or the like.SOLUTION: The vibration-proof rubber composition comprises a diene rubber composition containing the following (A)-(C) and the following (D) and (E): (A) a diene rubber; (B) silica; (C) a silane coupling agent; (D) N-oxydiethylene-2-benzothiazolylsulfenamide; and (E) di-2-benzothiazolyl disulfide. The total content of (D) and (E) is 1-5 pts.mass based on 100 pts.mass of (A), and the mass ratio of (D) to (E) is (D):(E)=90:10-50:50.SELECTED DRAWING: None
