Since 1990s, sulfur-functional silanes with silica filler have been used widely in the green to balance the magic-triangle properties of tire teads. Recently, the various silane coupling agents are used with silica filler for improve performance (magic-triangle properties) such as rolling resistance, wet traction and trade wear of tire treads.1-3 Sulfur-functional organosilanes, such as 3-mercaptopropyltrimethoxysilane (MPTMS) and bis-(triethoxysilylpropyl)tetrasulphide (TESPT), can be more increased mechanical properties than other functional silanes in existing simple mixed method (in situ method).4 However, it is known that SBR-MPTMS system has disadvantage of short vulcanization time and SBR-TESPT system has disadvantage of incompletely hydrolyzed in compounding step. The incomplete hydrolyzed alkoxy-functional groups can cause volatile organic compounds (VOCs) and decreased performance in SBR/BR compounds.5 This study explains influence of completely hydrolyzed TESPT and then treated silica affording hydrophobic and reactive modified silica applicable to SBR/BR compounds of tire tread. In addition, SBR/BR-modified silica with olefinic-functional silanes compared the properties of SBR/BR-simple mixed silica with olefinic alkoxysilane and SBR/BR-modified silica with sulfur-functional silane.
