Filamentous Material for Rubber Reinforcement Having Excellent Corrosion Resistance, and a Composite Material of the Filamentous Material for Rubber Reinforcement and a Rubber |
摘要 |
This invention provides a filamentous material for rubber reinforcement having excellent corrosion resistance, comprising: a steel filament and a coating layer containing Cu and Zn on a surface of the steel filament, wherein: a sum total in a length of a peripheral direction of the steel filament in a peripheral direction area in which the coating layer has a thickness of not less than 0.1 micrometers is not less than 50% in a full length in the peripheral direction of the steel filament when a cross section perpendicular to a longitudinal direction of the filamentous material is observed, and in the above peripheral direction area, (1) an average Cu content is 50% to 95% by mass in a depth direction area extending from an outermost surface of the coating layer to a position having a depth of 0.01 micrometers, and (2) an average Zn content is not less than 60% by mass in a depth direction area extending from a position having a depth of 0.1 micrometers of the coating layer to the outermost surface of the steel filament.
