Title:
防振部材
Document Type and Number:
Japanese Patent JP6702313
Kind Code:
B2
Abstract:
The present invention provides a vibration-absorbing rubber composition that is characterized by containing: a rubber component which contains natural rubber or a mixture of natural rubber and a diene-based synthetic rubber as a primary component; bismaleimide; and a metal salt of a dithiocarbamic acid having a benzene ring. According to this vibration-absorbing rubber composition, it is possible to improve changes in static spring and improve permanent compression set while maintaining inherent characteristics such as low dynamic magnification and strength characteristics (hardness, tensile elongation, tensile strength and the like), and this vibration-absorbing rubber composition is useful as a vibration-absorbing member which requires extreme heat resistance, such as an engine mount.
