Effect of In-Situ Bonding System and Surface Modification of Montmorillonite on the Properties of Butyl Rubber/MMT Composites

摘要

Isobutylene-isoprene rubber (IIR)/nanoclay composites were prepared by solution intercalation method. Cloisite Na~+ nanoclays and organo-modified montmorillonite (OMT) Cloisite 10 A,. 15 A and 20 A were used in this study. The effect of In-situ bonding system HRH (hexametylene tetramine: resorcinol: hydrated silica) on the dispersion of used nanoclays in the rubber matrix were examined by X-ray diffraction and atomic force microscopy (AFM). Characterization of the prepared composites was performed by studying the rheometeric and mechanical properties. The burning out behavior of the nanocomposites with and without the bonding system was also measured.
