The present invention relates to a method for preparing a rubber composition which can improve physical properties of a final product. In order to achieve the purpose of the present invention, the present invention comprises a step of preparing a polymer-dispersed rubber composition in which a polymer is dispersed in a solution phase in rubber and provides a method for preparing a rubber composition, wherein the step of preparing a polymer-dispersed rubber composition comprises, after polymerization of a rubber composition containing a monomer, a solvent, and a catalyst in a rubber preparation processing step, collecting a residual monomer, and introducing a polymer to a remaining rubber solution from which the residual monomer has been collected. Application of the rubber composition thus prepared, to a tire tread composite can improve durability, grip properties, low balanced rotation resistance, thus achieving effects of excellent braking and fuel-efficient characteristics, and improving abrasive wear performance. La présente invention concerne un procédé de préparation d'une composition de caoutchouc qui peut améliorer les propriétés physiques d'un produit final. Afin d'atteindre l'objectif de la présente invention, la présente invention comprend une étape de préparation d'une composition de caoutchouc dispersée dans un polymère dans laquelle un polymère est dispersé dans une phase de solution dans du caoutchouc et concerne un procédé de préparation d'une composition de caoutchouc, l'étape de préparation d'une composition de caoutchouc dispersée dans un polymère comprenant, après polymérisation d'une composition de caoutchouc contenant un monomère, un solvant, et un catalyseur dans une étape de traitement de préparation de caoutchouc, la collecte d'un monomère résiduel, et l'introduction d'un polymère dans une solution de caoutchouc restante à partir de laquelle le monomère résiduel a été collecté. L'application de la composition de caoutchouc ainsi préparée à un composite de bande de roulement de pneu peut améliorer la durabilité, les propriétés d'adhérence, la faible résistance à la rotation équilibrée, ce qui permet d'obtenir des effets d'excellentes caractéristiques de freinage et d'économies de carburant, et d'améliorer les performances d'usure par abrasion. 본 발명은 최종 제품의 물성을 개선할 수 있는 고무 조성물의 제조방법에 관한 것이다. 본 발명의 목적을 달성하기 위하여 본 발명은 고무에 폴리머가 용액상으로 분산된, 폴리머 분산 고무 조성물을 제조하는 단계를 포함하고, 상기 폴리머 분산 고무 조성물의 제조단계는 고무 제조 공정단계에서, 단량체, 용제 및 촉매를 포함하는 고무 조성물을 중합 반응시킨 후 잔류 단량체를 회수한 후 상기 잔류 단량체를 회수한 후 남은 고무 용액에 폴리머를 투입하는 단계를 포함하는 고무 조성물의 제조방법을 제공한다. 이렇게 제조 된 고무 조성물을 타이어 트레드 복합재에 적용 하면 내구성, 그립(grip)성, 낮은 회전저항성이 개선되어 우수한 제동 특성, 저연비 특성 및 마모성능이 향상 되는 결과를 얻을 수 있다.
