Abstract
The present invention provides a metal cord having better adhesion to rubber compared to a conventional one, as well as a metal cord-rubber composite and a conveyor belt, including the same. In a metal cord (10) composed of a plurality of metal filaments (11) twisted together, the surfaces of the metal filaments (11) constituting the outermost layer are each provided with a zinc plating layer (16), and the degrees of crystal orientation of the (002) plane and the (102) plane of the surface of the zinc plating layer (16) are less than 120.
Claims20
A metal cord composed of a plurality of metal filaments twisted together,
- characterized in that surfaces of the metal filaments constituting an outermost layer are each provided with a zinc plating layer,
- wherein degrees of crystal orientation F(002) and F(102) of the (002) plane and the (102) plane of a surface of the zinc plating layer, as represented by the following Formulae (1) and (2), respectively, are less than 120:
- F(002)−(R1(002)/R0(002))×100(%) (1)
- F(102)−(R1(102)/R0(102))×100(%) (2)
- where:
- in Formula (1),
- R0(002) represents the diffraction peak intensity of the (002) plane of non-oriented zinc, which is 22.1, and R1(002) represents the diffraction peak intensity of the (002) plane of an evaluation sample of zinc;
- and
- in Formula (2),
- R0(102) represents the diffraction peak intensity of the (102) plane of non-oriented zinc, which is 8.4, and R1(102) represents the diffraction peak intensity of the (102) plane of the evaluation sample of zinc.
