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.
本发明提供了一种吸振橡胶组合物,其特征在于含有:以天然橡胶或天然橡胶与二烯基合成橡胶的混合物为主要成分的橡胶成分;双马来酰亚胺;以及具有苯环的二硫代氨基甲酸的金属盐。根据这种吸振橡胶组合物,可以在保持低动态放大率和强度特性(硬度、拉伸伸长率、拉伸强度等)等固有特性的同时,改善静态弹簧的变化和永久压缩永久变形。
