  • Publication number: 20220186000
    Abstract: A method for preparing a rubber composition capable of improving the physical properties of a final product is disclosed. A rubber composition is prepared by dispersing polybutene in rubber in a solution phase (PIB extended rubber). The method comprises dispersing hydrophobic extender oil and polybutene in water to prepare an extender oil/polybutene emulsion; adding the extender emulsion to a latex-shaped rubber composition and uniformly dispersing the same in a solution to prepare a rubber/extension oil/polybutene composition; and solidifying, drying and molding the composition in a latex shape through salting-out and acid precipitation. When the rubber composition is applied to a tire tread composite material, the durability, grip property and low rotational resistance are improved, thereby attaining improved braking characteristic, low fuel consumption characteristic, and wear performance.
