Composite of rubber and metal reinforcement therefor

A composite of rubber composition containing zinc oxide, carbon black, optionally and/or mineral fillers, cure accelerator(s), fatty acid and/or metal salt thereof, and filament reinforcement therefor where said filament is selected from at least one of steel, organic and inorganic filaments, optionally as a multiple of filaments cabled together to form a cord, characterized in that (i) when said filament or cord thereof is steel, said rubber composition contains (A) about 0.05 to 8 phr of a compound selected from at least one of diallyl cyanurate, triallyl cyanurate, tris(2-hydroxyethyl) cyanurate, triphenyl cyanurate, diallyl isocyanurate, triallyl isocyanurate, and 4-ketobenz triazine and, optionally, (B) about 0.05 to about 10 phr of at least one borate as the product of (i) a metal selected from Groups IA, IIA, IIB, IVA, IVB, and VIII of the Periodic Table of the Elements, and (ii) an acid selected from the group consisting of boric, orthoboric, metaboric or polyboric acid;

• and when said filament or cord thereof is not steel the rubber composition contains both the (A) compound and the (B) borate.
