RUBBER COMPOSITION COMPRISING TERMINAL END-MODIFIED STYRENE-BUTADIENE RUBBER AND EPOXIDIZED NATURAL RUBBER AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to rubber composition comprising terminal end-modified styrene-butadiene rubber and epoxidized natural rubber, and to a production method thereof. More specifically, the present invention relates to a rubber composition which comprises terminal end-modified styrene-butadiene rubber and epoxidized natural rubber in order to allow hydrophilic silica to be uniformly dispersed in a hydrophobic rubber component without using silane as a coupling agent for mixing silica. In addition, by introducing more improved processes compared to a conventional process, dispersibility of silica is implemented to a level enough to be applicable to a product such as a tire. The present invention further relates to a method for producing the rubber composition with enhanced processing efficiency and production efficiency.;COPYRIGHT KIPO 2016
