Composite of steel cord and rubber composition and tire using the same

摘要

A steel cord-rubber composite (10) is provided, that has improved initial adhesion property and adhesion property against aging between the steel cord and the rubber composition with improved manufacturing cost efficiency. A steel cord-rubber composition composite includes a coating layer and a steel cord (1), and the coating layer includes an inner coating layer (2) formed of a rubber composition containing a rubber component, a cobalt compound and sulfur and directly covering the steel cord, and an outer coating layer (3) formed of a rubber composition of which contents of cobalt compound and sulfur are smaller than those of the inner coating layer and coating the outer portion of the inner coating layer.
