Abstract
The use of silica with sulphur-functional organosilanes, such as 3-mercaptopropyltrimethoxysilane (MPTMS) and bis-(triethoxysilylpropyl)tetrasulphide (TESPT), in SBR compound has increased performance. It is known that MPTMS has disadvantage of short vulcanization time. On the other hand, Bifunctional oganosilanes, such as TESPT, are very efficient silica-rubber coupling agents. However, it is known that TESPT cannot be completely hydrolyzed in compounding step. Incomplete hydrolyzed alkoxy-functional groups can cause volatile organic compounds (VOC) and decreased performance in SBR compounds. In this study, completely hydrolyzed TESPT and then treated silica affording hydrophobic and reactive modified silica applicable to tire tread compounds.
