Document Type and Number:
Japanese Patent JP7037986
Kind Code:
B2
Abstract:
To provide an electric vehicle vibration-proof rubber composition and electric vehicle vibration proof rubber member, capable of achieving both the reduction of dynamic modulus of elasticity and a low dynamic-to-static modulus ratio to high frequency vibration without causing reduction of physical properties, such as the static modulus of elasticity.SOLUTION: An electric vehicle vibration-proof rubber composition using the following (A) component as a main component and including the following (B) component and (C) component has 3-40 pts.wt of the content of the (B) component to the following (A) component of 100 pts.wt.. (A) diene based rubber: (B) carbon black and (C) at least one of (2Z)-4-[(4-amino-phenyl)amino]-4-oxo-2-butene acid sodium: and thiosulfuric acid S-(3-aminopropyl).SELECTED DRAWING: None
