Title: METAL CORD-RUBBER COMPOSITE BODY
Abstract:
The present invention is a metal cord-rubber composite body obtained by coating one of the following with a rubber composition: a metal cord that comprises a single steel wire having brass plating on the circumferential surface thereof; or a metal cord obtained by twisting together a plurality of the steel wires. The metal cord-rubber composite body is characterized in that: the rubber composition is obtained by blending a rubber component (A) and 0.1-10 parts by mass of a resorcinol resin with respect to 100 parts by mass of the resin component (A); and the brass plating is three-element or four-element plating comprising 58-70 mass% of Cu, 0.5-10 mass% of at least one metal selected from Co and Ni, and a remainder of Zn. By coating a metal cord having three-element or four-element plating that is specific brass plating with a specific rubber composition in a rubber product reinforced by a metal cord, the present invention provides a metal cord-rubber composite body having improved adhesiveness.
