카르복실화 SBR 라텍스와 산화아연을 이용한 SBS의 내마모성과 데브리스(debris) 개선 연구 = Improvement of Abrasion and Debris on Styrene-Butadiene-Styrene Block Copolymer with Carboxylated SBR Latex and Zinc Oxide

다국어 초록 (Multilingual Abstract)

In this study, we observed the effect of carboxylated SBR latex and zinc oxide on styrene-butadiene-styrene( SBS) composites for improving abrasion and debris. SBS composite, which added only silica, showed poor mechanical properties, NBS abrasion, and debris, caused by strong filler-filler interaction of silica. In case of adding carboxylated SBR latex, mechanical properties, NBS abrasion and debris of SBS composite were improved. Because of carboxyl group of carboxylated SBR latex interacted with silanol group of silica. Both carboxylated SBR latex and zinc oxide were added, SBS composite showed highest mechanical properties, NBS abrasion, and debris by forming ion cluster between carboxylated SBR latex and zinc oxide. By FT-IR analysis, ion clusters were confirmed that observed zinc carboxylated group stretch peak at 1550~1650cm-1 range. SBS composite, SC-4, showed excellent mechanical properties ; tensile strength 156kgf/cm2, elongation 936%, tear strength 59.4kgf/cm ; and excellent abrasion characteristics ; NBS abrasion 338%. Also, debris of SC-4 was minimized and showed wave-shape in fracture surface.
