Method for evaluating abrasion resistance of rubber composition and rubber composition

Abstract

Provided is a highly accurate method for evaluating the abrasion resistance of rubber compositions. The present disclosure relates to a method for evaluating abrasion resistance of a rubber composition by X-ray scattering measurement or neutron scattering measurement, the method including performing X-ray scattering measurement or neutron scattering measurement in a region q expressed by the following Formula 1 to obtain a scattering intensity curve I(q), fitting the following Formula 2 to the scattering intensity curve I(q) to obtain a mass fractal dimension D, and evaluating the abrasion resistance of the rubber composition based on the mass fractal dimension D, q = 4 ⁢ π ⁢ sin ⁢ ( θ / 2 ) λ ( Formula ⁢ 1 ) ( e : scattering ⁢ angle , λ : wavelength ⁢ of ⁢ x - rays ⁢ or ⁢ neutrons ) I ( q ) ∝ q - D ( Formula ⁢ 2 ) ( D : mass ⁢ fractal ⁢ dimension ) .
