Abstract:
1. A rubber composite comprising: rubber; and a metal material which has an adhesion boundary surface adhered to the rubber and which reinforces the rubber, wherein the adhesion boundary surface has a crystal structure of an anti-fluorite structure, the rubber is vulcanized by use of a sulfenamide compound as a vulcanization accelerator, a bond order between an amine of the sulfenamide compound and the adhesion boundary surface is zero, the bond order being calculated by use of an AM1 method as a semi-empirical molecular orbital calculation method, the bond distance between a sulfur atom and a nitrogen atom in the sulfenamide is less than 1.67 Å, the bond distance being determined by use of a basis function B3LYP/6-31G (2df, p) as an ab initio molecular orbital calculation method, and the electric charge on nitrogen of an amine radical generated by dissociation between the sulfur atom and the nitrogen atom of the amine is −0.295 or less, the electric charge being determined by calculating molecular orbitals of an amine radical with a basis function ROMP2/G3MP2large, and then performing an NBO analysis on the molecular orbitals.
