| description | To provide a method for producing a masterbatch capable of efficiently reducing the moisture content of a coagulated product.SOLUTION: There is provided a method for producing a masterbatch which comprises a step of mixing at least a filler slurry and a natural rubber latex to prepare a mixed solution and a step of adding a coagulant into the mixed solution so that the pH is 5.0 or more and less than 8.0. Since a coagulant is added into the mixed solution so that the pH is 5.0 or more, the moisture content of a coagulated product can be efficiently reduced. The surface properties of a coagulated product become a state having adhesiveness suitable for pressing or kneading (for example, a state having suitable adhesiveness capable of reducing or suppressing a slip which may occur during pressing or kneading by an extruder) by adding a coagulant into the mixed solution so that the pH is 5.0 or more, as a result, it is believed that a coagulated product can be efficiently pressed and kneaded.SELECTED DRAWING: None
【課題】凝固物の水分量を効率的に低減することができるマスターバッチの製造方法を提供することを目的とする。【解決手段】本発明のマスターバッチの製造方法は、少なくとも充てん剤スラリーおよび天然ゴムラテックスを混合し、混合液を作製する工程と、前記混合液に、ｐＨが５．０以上８．０未満となるように凝固剤を添加する工程とを含む。混合液に、ｐＨが５．０以上となるように凝固剤を添加するため、凝固物の水分量を効率的に低減することができる。これは、混合液に、ｐＨが５．０以上となるように凝固剤を添加することによって、凝固物の表面性状が、圧搾や混練にとって適度な粘着性を有する状態（たとえば、押出機による圧搾や混練中に生じ得るスリップを低減または抑制可能な、適度な粘着性を有する状態）になり、その結果、凝固物を効果的に圧搾や混練できるためだと考えられる。【選択図】なし |
