Abstract
Official abstract text for this publication.
The present invention relates to a brass-plated steel cord capable of further improving initial adhesiveness and heat-resistant adhesiveness between a coating rubber and a steel cord and also imparting excellent durability to a resulting rubber article, and more particularly to a brass-plated steel cord, wherein an outermost surface thereof contains 0.3 to 1.7 atomic % of phosphorus, 4.93 to 14 atomic % of zinc, and 0.01 to 2.0 atomic % of a metal having an ionization tendency lower than that of zinc and higher than that of copper as measured by XPS (X-ray photoelectron spectroscopy), and an amount of zinc in the outermost surface is 30 to 90 atomic % based on 100 atomic % of a total amount of zinc and copper.
First claim
Opening claim text (preview).
The invention claimed is: 1. A steel cord-rubber composite formed by coating a brass-plated steel cord with a rubber composition comprising sulfur, wherein an outermost surface of the brass-plated steel cord contains 0.3 to 1.7 atomic % of phosphorus, 7.0 to 14 atomic % of zinc, and 0.01 to 2.0 atomic % of a metal having an ionization tendency lower than that of zinc and higher than that of copper as measured by XPS (X-ray photoelectron spectroscopy), and an amount of zinc in the outermost surface is 30 to 90 atomic % based on 100 atomic % of a total amount of zinc and copper. 2. The steel cord-rubber composite according to claim 1 , wherein the rubber composition comprises 1 to 10 parts by mass of the sulfur based on 100 parts by mass of a rubber component. 3. The steel cord-rubber composite according to claim 1 , wherein the rubber composition comprises 0.005 to 0.08 part by mass in terms of boron of a boron-containing compound based on 100 parts by mass of a rubber component. 4. The steel cord-rubber composite according to claim 1 , wherein the rubber composition does not contain cobalt. 5. A tire using the steel cord-rubber composite as claimed in claim 1 as a reinforcing member.
