<p>Provided is a rubber-steel cord composite which is excellent in workability and which is markedly excellent in tensile characteristics, an adhesive property after vulcanization for a short time and a heat resistant adhesive property. The rubber-steel cord composite has such a constitution that a steel cord which has a brass-plated layer on a peripheral surface thereof and in which a content of phosphorus contained in the form of oxide in a wire surface layer region extending from a surface of the above brass-plated layer up to a depth of 5 nm in a wire radial direction toward the inside is 1.5 atomic % or less is adjacent to a rubber composition containing a rubber component, sulfur and a sulfeneamide base vulcanization accelerator represented by the following Formula (I):
(wherein R 1 is a branched alkyl group having 3 to 12 carbon atoms; R 2 is a linear alkyl group having 1 to 10 carbon atoms; R 3 to R 6 are a hydrogen atom, a linear alkyl group or alkoxy group having 1 to 4 carbon atoms or a branched alkyl group or alkoxy group having 3 to 4 carbon atoms, and they may be the same or different; x is an integer of 1 or 2, and n is an integer of 0 or 1).</p> |
