Rubber composition for tires, method for preparing rubber composition for tires, and tire |
| abstract |
Provided are a rubber composition for tires having low tan δ at approximately 60° C. and excellent breaking energy at approximately 25° C.; a method for preparing the rubber composition for tires; and a tire thereof. The present invention relates to a rubber composition for tires which contains a rubber component including an isoprene-based rubber, and which has a correlation length Ξb of 50 nm or less as determined by fitting the following Equations 1 to 6 to a scattering intensity curve I(q) obtained by X-ray scattering analysis or neutron scattering analysis:I(q)=A1+q2ξ2+B(1+q2Ξb2)2+C(1+q2Ξc2)2(Equation1)ξ<Ξb<Ξc(Equation2)A=8πNaσ2ξ3(Equation3)B=4πNbσ2Ξb2(Equation4)C=4πNcσ2Ξc2(Equation5)q=4πsinθ2λ(Equation6)A, B, C, ξ, Ξb, Ξc: fitting parameterq: scattering vectorNa: number per unit volume (number/cm3) of scatterers having a correlation length ξNb: number per unit volume (number/cm3) of scatterers having a correlation length ΞbNc: number per unit volume (number/cm3) of scatterers having a correlation length Ξcσ: electron density difference (electron·(cm−3)) between scatterers and the surrounding matrix or scattering length density difference (cm−2) between scatterers and the surrounding solventθ: scattering angleλ: wavelength of X rays or neutrons. |
