T he higher silica content in the tire-tread rubber can
maximize the efficiency of the vehicle. However, silica
does not mix well with other mixtures, including the tire-tread
rubber. This phenomenon deteriorates the various properties
of the tire-tread rubber. Therefore, we have tried to improve
the dispersity of silica in tire-tread rubber by using dispersant.
The dispersion of silica in tire-tread styrene-butadiene rubber
(SBR) is one of important factors in the mechanical properties
of it. We prepared dispersants to enhance silica content and
dispersity in SBR using wet master batch (WMB) system. The
dispersants were prepared by copolymerization of styrene with
allyl alcohol or methyl methacrylate. The synthetic conditions
of dispersants were changed to improve the silica loading
content and dispersity in WMB system for the preparation of
silica-SBR composites. The WMB system was consisted of
the steps involving dispersants synthesis, silica modification,
dispersion of modified silica in SBR emulsion latex, and
coagulation of silica-SBR composites. We confirmed the
structure of the dispersants using FT-IR. The content of silica in
the composites was measured by thermal gravimetric analysis
(TGA) according to the types of dispersants. We also studied
the payne effect with rubber process analyzer (RPA) instrument
and dynamic viscoelasticity with Dynamic mechanical analysis
(DMA) instrument. We measured the mechanical properties of
them such as tensile strength and modulus of M300. We found
the optimal types and content of dispersants for silica-SBR
composites.
