Abstract

The role of the aspect ratio of the clay, OMMT and MMT on the thermal stability, mechanical properties and flame retardancy of NBR/clay composites was investigated. NBR was mechanically mixed with clay via melt blending method. The dispersi on of clay in the NBR matrix was also studied by XRD . The results of XRD indicated that the composites belong ed to the exfoliated and interlayer structure respectively. The OMMT has better dispersity in the NBR matrix than the MMT. The torque of NBR/OMMT c omposite was higher than that of NBR/MMT composite and pure NBR composite. NBR/OMMT nanocomposites and NBR /MMT composites exhibited excellent mechanical properties, thermal stability and flame retardancy It s obvious that t he OMMT filled nanocomposites ha s far better properties than that of MMT filled NBR and unfilled NBR ..
