Structure and Properties of Hydrogenated Nitrile-Butadiene Rubber/organo montmorillonite Nanocomposites

摘要：

Organo-montmorillonite (OMMT) was compounded with Hydrogenated Nitrile-Butadiene Rubber HNBR (50％ epoxidation) to prepare nanocomposites by melt mixing method. The nanometer scales of organoclays in rubber matrix were determined by X-ray diffraction testing, the exfoliated/intercalated structures of OMMT in HNBR were confirmed by transmission elector microscopy. The increases in tensile module and strength of HNBR/OMMT nanocomposites vulcanizaters were caused by the better interactions between rubber macromolecule chains and organoclay layers. The airaging properties of nanocomposites enhanced by the increasing content of OMMT, which was leaded by the barrier characterize of nano-disperse OMMT layers. DMA test showed that the Tgs of HNBR/OMMT shifted to a higher temperature, as verified by the crosslinking density determination.
