Document Type and Number:
WIPO Patent Application WO/2017/104251
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rubber composition for vibration-damping rubbers which is able to attain both a reduction in dynamic-to-static modulus ratio and an improvement in heat resistance. The rubber composition for vibration-damping rubbers comprises a rubber component comprising at least one diene-based rubber, a zinc oxide composite, and a bismaleimide compound. It is preferable that the rubber composition contain 2-40 parts by weight of the zinc oxide composite and 0.5-5 parts by weight of the bismaleimide compound per 100 parts by weight of the rubber component. The rubber composition especially preferably further contains sulfur in an amount of 0.05-1 part by weight.
