Statement of the problem: According to the Japan Rubber Manufacturers' Association, the total amount of carbon dioxide consumed
from each passenger tire is 296.4 kg. Approximate 87% (equivalent to 258 kg) of carbon dioxide is discharged at the stage of use.
The development of environmentally friendly energy-saving tires is the goal of global tires' manufacturers. Goodyear and Novamont
have collaborated to produce BioTRED using corn starch to replace parts of the lamp black and silica in rubber matrix. It has been
approved by both Ford and BMW. The purpose of this study is used non-food biomass resources such as typical starch and lignin
as renewable fillers in the styrene-butadiene system. Methodology & Theoretical Orientation: To develop the energy saving tires
with excellent wet traction and rolling resistance, the important fundamental properties such as viscoelastic behaviors of composite
materials were investigated. Findings: Thermoplastic starch (TPS) and lignin bio-fillers were used to replace parts of the carbon
black and silica, which were normally contained in the tire tread mixture. The starch/lignin were incorporated from 5 to 20 parts
per hundreds of rubber (phr). Dynamic Mechanical Analyzer (DMA) test confirmed these two kinds renewable fillers are helpful for
improving wet grasping performance (i.e., evaluated at tan
δ
0
0
C) and reducing the rolling resistance (i.e., evaluated at tan
δ
60
0
C)
of tire tread. The Payne Effect test showed that the incorporation of 15 phr modified TPS to replace silica could improve dispersion
of reinforcing fillers in rubber composited system. Conclusion & Significance: There are many advantages by introducing non-food
biomass renewable fillers to styrene-butadiene rubber system. They can enhance tire wet grip, lower rolling resistance, and reduce
carbon dioxide emissions. There is also a “lightweight” advantage because the density of TPS is just half of silica. Moreover, the energy
saving processing can be reached.
