AbstractPresent study describes the preparation and characterization of crystal violet modified-montmorillonite clay nanocomposites by latex blending technique. Coagulation of the latex-clay slurry produced nanocomposites master batch. The master batch was compounded with Styrene Butadiene rubber (SBR). WAXD and TEM provided the evidences of formation of nanocomposite. Remarkable improvements in the mechanical properties were found by addition of small amount of modified clay.

Recycling rubber waste contributes to a cleaner environment by using indestructible rubber discards as well as lowering production costs as reclaimed rubber is cheaper than virgin or natural rubber. Therefore, in this study, the properties of recycled acrylonitrile butadiene rubber glove (NBRgr) blending with styrene butadiene rubber (SBR) has been determined. The effects of SBR/NBRr blends on properties of such fourier transform infrared (FT-IR) and morphology properties were carried out. FT-IR analysis showed that SBR/NBRr R05 blended with the smallest size NBRr (S1) and showed most intense amine absorption at 1535 cm-1.The intensity decreased by increasing the NBRr sizes. By incorporating the smallest size NBRr provided more surface area to interact with SBR polymers thus increased the level of crosslink. From scanning electron microscopy (SEM) observation on fatigue failure surface, the SBR/NBRr blended with the finest size of NBRr (S1) showed roughest matrix tearing compared to S2 and S3 indicated better fatigue propagation. At higher blend ratio (50/50), the SBR/NBRr blended with S2 and S3 exhibited a coarser and a poorer distribution of NBRr with SBR matrix which led to lower fatigue life.

AbstractStyrene- butadiene rubber (SBR)/ clay nanocomposites were prepared by mixing the SBR latex with aqueous clay dispersion and co-coagulating the mixture. Tapping mode AFM and XRD were applied to characterize the structure of nanocomposites. It was found that fully exfoliated structure could be obtained by this method only when the low loading of layered silicate (< 10 phr) is used. With increasing the clay content, both non-exfoliated (stacked layers) and exfoliated structures can be observed simultaneously in the nanocomposites. The results of mechanical tests on the vulcanized pure SBR and SBR/ clay nanocomposites showed that the nanocomposites presents better mechanical properties than clayfree SBR vulcanizate. Furthermore, initial modulus, tensile strength, tensile strain at break, hardness (shore A) and tear strength increased with increasing the clay content, indicating the nanoreinforcement effect of clay on the mechanical properties of SBR/ clay nanocomposites. Compared to the clay free SBR vulcanizate, the nanocomposite vulcanizates exhibit a lower tanδ peak value, higher storage modulus and higher tanδ value at the rubbery region (0-60 °C) which indicate that the elastic responses of pure SBR towards deformation are strongly influenced by the presence of nanodisperced natural sodium montmorillonite layers especially completely exfoliated silicate layers.
