Abstract: Provided is a process for producing a wet masterbatch which, without deteriorating a reinforcing property of a rubber composition and rubber physical properties, micronizes a filler slurry by controlling an amount of functional groups on a filler surface, and improves filler dispersibility in the rubber wet masterbatch and the rubber composition. The process for producing a wet masterbatch comprises: a step of producing a slurry solution having a pH of 8 or more by dispersing carbon black having an average amount of surface acidic functional groups (μeq/m2) of 0.15 or more and less than 3.00; a step of producing a mixture by mixing the slurry solution and a rubber latex solution in a liquid phase; and a step of drying the mixture.

Abstract: The present invention provides highly dispersible precipitated silica having improved structure and properties for use as reinforcing filler in elastomeric compositions and method of preparation thereof. The present invention further provides an alkaline silicate solution having reduced dielectric constant by digesting biogenic silica source with alkaline solution such that soluble organic compounds present in the biogenic silica source leach into the alkaline silicate solution. The alkaline silicate solution obtained as above is then acidified with a mineral acid under particular conditions of pH, temperature, time etc. to obtain the highly dispersible precipitated silica of the present invention.
