摘要
Organo-montmorillonite was incorporated into model tire tread formulations through latex compounding methods, to evaluate its effects on elastomer reinforcement and dynamic properties. An intercalation structure was obtained by applying latex compounding method to prepare organoclay-emulsion stryene butadiene (E-SBR) masterbatches, for compounding with organoclay loading levels of 0-20 parts per hundred rubber (phr). Microstructure, curing properties and tire performance of the compounded rubber were investigated with the aid of X-ray diffraction, rheometor and dynamic-mechanical analysis, respectively. The results showed that organo-montmorillonite filler provided effective reinforcement in the elastomer matrix, as indicated through mechanical and dynamic mechanical properties. Tread compounds using higher organoclay loadings displayed preferred ice traction, wet traction, and dry handling, but decreased winter traction and rolling resistance. Model compounds using 15 phr of organoclay loading levels were preferred for balanced physical and dynamic properties.
