Preparation and Properties of NBR Nanocomposites Containing Montmorillonite

NBR Elastomer blends containing (0, 3, 5, 7) Wt% organo-nanoclay (Cloisite30B) were prepared by Haak Internal mixer. The effect of organo-modified layered nanosilicates on the microstructure, mechanical properties (abrasion resistance, hardness, fatigue etc.) and also cure characteristics of the nanocomposites were studied. Results suggested the intercalation of silicate layers in the nanocomposites which was evidenced by X-ray diffraction. Mechanical properties of nanocomposites depicted a great increase in the abrasion resistance with 7 Wt % nanoclay which coul be attributed to the good interaction between polymer/clay. A further investigation of the nanocomposites microstructure will soon be conducted using TEM
