Abstract

The HNBR/organo rectorite nanocomposites were prepared by the melt blending method. The mechanical properties, a kron abrasion and the crude oil medium ageing resistant of HNBR nanocomposites were examined as a function of the organ o rectorite content in the matrix of polymer. The effect of sulfur vulcanization on the dispersion of organo rectorite in the HNBR matrix was also investigated. The results of XRD indicated that the nanocomposites belong to exfoliated and intercalation structure. The test results show remarkable improve ment in the t ensile strength, tear strength and ageing r esistant of HNBR organo rectorite nanocomposites. It’ s obvious ly that the 8 phr of r ectorite filled nanocompo sites has far better mechanical properties than that of other phr and unfilled HNBR..
