Document Type and Number:
WIPO Patent Application WO/2023/163233
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a rubber composition that achieves both thermal deterioration resistance and fracture resistance. The solution to this problem is a rubber composition characterized by including a diene rubber (A), a heterocyclic compound (B) that has a six-membered aromatic heterocyclic ring, a metal salt (C) (with the exception of metal oxides, metal carbonates, and fatty acid metal salts having 10 or more carbon atoms), an organic peroxide (D), and a carbon black (E). The mass ratio (D/C) of the organic peroxide (D) to the metal salt (C) is preferably 0.1-10.
