Abstract
Official abstract text for this publication.
This disclosure is to provide a brass-plated steel wire for reinforcing a rubber article, which is capable of improving the initial adhesiveness, heat-resistant adhesiveness and initial adhesion rate. This disclosure is a brass-plated steel wire for reinforcing a rubber article, wherein: when measured with XPS (X-ray photoelectron spectroscopy), an outermost surface contains zinc at an amount of 4.8 atom % or less, phosphorus at an amount of 0.5 atom % or more, and oxygen at an amount of 50 atom % or less; and in the outermost surface, an atomic ratio of copper to zinc is 1 to 6.
First claim
Opening claim text (preview).
The invention claimed is: 1. A brass-plated steel wire for reinforcing a rubber article, wherein: when measured with XPS (X-ray photoelectron spectroscopy), an outermost surface contains zinc at an amount of 4.8 atom % or less, phosphorus at an amount of 0.5 atom % or more, and oxygen at an amount of 50.0 atom % or less; and in the outermost surface, an atomic ratio of copper to zinc is 1 to 6. 2. The brass-plated steel wire for reinforcing a rubber article according claim 1 , containing a metal having an ionization tendency less than zinc and more than copper at an amount of 0.010 to 2.0 atom %. 3. A rubber composition for coating a brass-plated steel wire for reinforcing a rubber article according to claim 1 , wherein an amount of cobalt is 0.1 parts by mass or less per 100 parts by mass of a rubber component of the rubber composition. 4. A tire comprising a brass-plated steel wire according to claim 1 . 5. A tire comprising a brass-plated steel wire according to claim 2 . 6. A tire comprising a composite of a brass-plated steel wire for reinforcing a rubber article comprising the rubber composition according to claim 3 .
