Abstract:
Energy-saving tires have been developed by
researchers in the industry in order to minimize hysteresis
loss. In general, this is achieved by combining precipitated
silica sourced from silica sand with a silane coupling agent.
This strategic reaction serves to elevate the performance
characteristics of tread tire, effectively enhancing their
properties. Therefore, this research is aimed to investigate
the utilization of commercially available biosilica compared
to high dispersed (HD) silica, examining their potential as
reinforcing agents in the composition of passenger tread tire
compound. This compound was formulated using a blend of
solution styrene-butadiene rubber (SSBR) and butadiene
rubber (BR). A comprehensive analysis was conducted to
assess the impact of varying ratios between biosilica and
HD silica on themechanical and dynamic properties of tread
tire compound composed of SSBR and BR blend. The results
showed that the incorporation of biosilica could effectively
reduce the filler network resulting in better dispersion of
biosilica in the SSBR/BR blend matrix. As a result, it improved
wet grip (44%) and rolling resistance (26%) while maintaining
abrasion resistance compared with HD silica in passenger
tread tire compound. The application of biosilica as an ecofriendly
reinforcement material exhibited its potential for
elevating the performance of energy-efficient tread tire.
