Document Type and Number:
WIPO Patent Application WO/2020/226170
Kind Code:
A1
Abstract:
The present invention provides a feature with which it is possible to improve the strength characteristics of an adhesion interface between a metal wire for rubber reinforcement and rubber, and inhibit oxidative degradation of the rubber and improve the durability of the rubber. The present invention provides a metal wire 1 for rubber reinforcement in which a brass plating layer containing copper and zinc is provided on the surface thereof, wherein cobalt is contained in the surface layer of the brass plating layer 30b, and the cobalt concentration at the surface of the brass plating layer 30b is 3 to 7 atom% inclusive. The need to have the rubber contain cobalt in advance is thereby obviated, making it possible to inhibit rubber degradation due to oxidation of cobalt.
