Biography

Min Seong Kim is currently pursuing Master’s course in Materials and Chemical Engineering at Hanyang University, Republic of South Korea. He studied synthesis of silica dispersant for the tire tread rubber at the Korea Institute of Industrial Technology (KITECH), Republic of South Korea. He is mainly interested in researching new knowledge through the fusion of inorganic and organic materials.

Abstract

The agglomeration of silica-silica in Si-SBR composites deteriorate the many properties of the tire tread rubber. We prepared various dispersants to improve the dispersibility of silica in Si-SBR composites: poly (itaconic acid-co-acrylamide), poly(styrene-co-allyl alcohol), poly(styrene-co-methyl methacrylate), and poly(glycidyl methacrylate-co-styrene). We confirmed the structure and molecular weight of the dispersants using FT-IR and GPC, respectively. The silica loading content in SBR/silica composites was determined using thermal gravimetric analysis. We also investigated curing characteristics, morphology, Payne effect of the Si-SBR composites according to the types of dispersant. As a result, we were able to compare the effect of silica dispersion in the composites
