The rubber composite was fabricated by use of direct vulcanization adhesion method with a sulfenamide-based vulcanization accelerators, and the sulfenamide-based vulcanization accelerator is used for a rubber composite using a sulfenamide compound as a vulcanization accelerator, the adhesion properties of the steel cord/rubber adhesion boundary surface and the anti-scorch properties can be achieved simultaneously, the sulfenamide-based vulcanization accelerator being such that the bond order between an amine generated form the sulfenamide compound and a surface of a metal material is zero, and the distance of the S-N (amine moiety) bond of the sulfenamide compound is less than 1.67 Å, and the electric charge on N of the amine radical generated as a result of dissociation of the S-N bond is -0.295 or less.
