New Tin-Functionalized Integrated Rubber for High Performance Green Tire Tread

Article Preview

Abstract:

A novel Tin-functionalized integrated rubber of styrene-isoprene-butadiene tri-copolymer (SIBR) was prepared in the styrene (St)/isoprene (Ip) /butadiene (Bd) system with self-made tin-containing organolithium (simplified as SnLi) as initiator via living anionic polymerization. By means of several measures such as TEM, SEM and dynamic viscoelastometer, morphology, static mechanical properties, wear ability, dynamic heat build-up and dynamic viscoelasticity of Tin-functionalized SIBR (Sn-SIBR) were studied and compared with non-functionalized SIBR and NR/S-SBR (40/60) blend. The result shows that with improving antiskid properties and wear resistance, Sn-SIBR reduces the rolling resistance over 30%, which has excellent mechanic properties and dynamic properties. Sn-SIBR satisfies the overall property requirements of high-performance tire tread, and it is an ideal new style tread material for high-property environmental green tire.
