dc.description.abstract The purpose of this research was to study the feasibility of lignin as an antioxidant for tire tread compounds. Lignin is naturally abundant and cost competitive wood derivatives possessing antioxidant properties and offering reactive functional groups on their surfaces. Further, lignin is a natural, non-hazardous and sufficiently bio degradable material. The present study deals with a natural rubber based tire tread compound containing different antioxidant combinations. Lignin as a bio polymer was combined with commercially available antioxidants (6PPD and SKF) to investigate from the view point of their thermo-oxidative aging. The research specifically focused on producing tire tread compound for industrial applications. Physico-mechanical properties such as tensile properties tear strength, hardness, abrasion and flexing, and cure characteristics, on tire tread compound was investigated before and after thermo-oxidative aging. The results obtained are shown that the lignin exerts a stabilizing effect. Moreover lignin blends with the selected antioxidants increased the stabilization effect. The conclusion extracted from this study demonstrates that the higher potential of using lignin as a natural antioxidant substitute for commercial tire tread compounds en_US
