Abstract
The using silane coupling agents with silica filler were sulfur-functional silanes and ally-functional silanes for improve performance of SBR composite of tire tread.l-3 The SBR composite with sulfurfunctional organosilanes, such as 3-mercaptopropyltrimethoxysilane (MPTMS) and bis- (triethoxysilylpropyl)tetrasulphide (TESPT), can be more increased performance than ally-functional silanes in existing simple mixed method.a 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 compounds.t In this study, completely hydrolyzed TESPT and then treated silica affording hydrophobic and reactive modified silica applicable to SBR composite of tire tread. In addition, SBR-modified silica with allyl- functional silanes compared the properties of SBR-simple mixed silica with alkenylalkoxysilane and SBR-modified silica with sulfurfunctional silane.
