Abstract
The effects of mixing geometry (intermeshing vs. tangential rotor) for the dispersion and distribution of silica agglomerates in SBR/BR compound were investigated. Silica dispersion and distribution were found to be better with the intermeshing rotor compared to the tangential rotor. It was concluded that the intermeshing rotor compared to the tangential rotor delivered a higher shear stress due to interlocked rotor geometry to silica agglomerates leading to better dispersity and distribution of silica in the agglomerates.

실리카로 충전된 SBR(styrene butadiene rubber)/BR(butadiene rubber) 합성고무 복합소재에 대해서 가공기기의 구조가 실리카 분산에 미치는 영향을 파악하기 위해 주사전자 현미경(SEM-scanning electron microscope)을 이용하여 컴파운드의 모폴로지를 관찰하였다. Internal mixer 내에서 intermeshing rotor와 tangential rotor에 의해 배합된 컴파운드를 비교한 결과, intermeshing rotor에 의해 가공되었을 경우 실리카 입자가 더 고르게 분산 및 분포되었음을 관찰하였다. Rotor의 geometry 차이에 의해 intermeshing rotor가 tangential rotor보다 더 큰 전단력(shear)을 컴파운드에 전달하여 실리카 입자를 효과적으로 분산 및 분배시킨 것으로 판단된다.

Keywords: tangential rotor; intermeshing rotor; silica dispersion; SEM(scanning electron microscope); synthetic rubber (SBR/BR).
