摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for coating a steel cord that improves both aging prevention performance and adhesion to the steel cord while not reducing moldability. SOLUTION: Based on 100 pts.wt of diene-based rubber, an organic acid cobalt salt with a cobalt amount of 0.1-0.3 pts.wt and 0.01-5 pts.wt of a tea extract including catechin are blended. The tea extract includes catechin and tea polyphenol other than the catechin. COPYRIGHT: (C)2011,JPO&INPIT
