摘要： A problem which is addressed is the provision of a method for manufacturing a wet rubber masterbatch that will serve as raw material for vulcanized rubber which excels in fatigue resistance, ability to achieve reduced heat generation, and tensile characteristics.A wet rubber masterbatch is manufactured by means of a method comprising an operation in which a latex that has magnesium present therein in an amount which is not greater than 150 ppm is prepared; an operation in which a liquid mixture is made; and an operation in which the liquid mixture is coagulated to obtain a coagulum. The latex comprises rubber particles for which the 90 vol % particle diameter is not greater than 2 μm. The operation in which the liquid mixture is made comprises a step in which the latex and a dispersion solvent are mixed together. The operation in which the liquid mixture is made further comprises a step in which a slurry that contains filler and a latex solution obtained as a result of the step in which the latex and the dispersion solvent were mixed are mixed together. The operation in which the coagulum is obtained comprises a step in which the coagulum is separated from waste liquid. The method for manufacturing the wet rubber masterbatch satisfies Formula I, below. a/b≥65 (Formula I) (At Formula I, a indicates COD (mg/L) of waste liquid, and b indicates amount (mass %) of rubber present in the liquid mixture.)

摘要： The present disclosure provides for a process for manufacturing of dipped latex products without using any animal derived ingredients and dipped latex products produced by said process. The disclosed process successfully over comes drawbacks of drop in product yield (due to coagulum formation) and burst pressures caused by absence-of casein in latex formulation. Therefore, the dipped latex products so produced through the process have final composition similar to that of any other dipped latex products with casein except for absence of casein and having 0.8 phr of Sulphur as against 0.6 phr of Sulphur in routine manufacturing. The products also exhibit physical properties similar to that of any other dipped latex products with casein, such as burst pressure and burst volume.
