摘要
SBR compounds including the N-isopropyl-N＇-phenyl-p-phenylenediamine-modified clay（organoclay） were prepared.Effects of modified clay and antioxidant（IPPD） contents on mechanical and rheological properties of SBR composites were studied.FTIR results confirmed that the clay was chemically modified by IPPD and changed into an organoclay.X-ray diffraction（XRD） results confirmed the increase in interlayer distance of the clay due to the insertion of IPPD.Rheological and cure characteristics of SBR compounds were determined using RPA（Rubber Process Analyzer） and rheometer.Scorch time and cure time of SBR compounds decreased with introduction of the organoclay.Mechanical properties and heat aging resistance of the SBR composites were improved significantly by incorporation of the organoclay.
