Mechanical and rheological properties of nitrile rubber/fluoromica composites

Fluoromica is a clay mineral obtained from chemical modification of talc with Na2SiF6. In this study, it was used to prepare clay mineral polymer composites (CPN) based on nitrile rubber. The composites were compounded in a roll mill and it was studied the effect of the fluoromica content as well as the shear ratio employed during the preparation. The composites were assessed based on the mechanical properties, dynamic-mechanical performances, rheological properties, and morphological aspects. The results suggested that the formation of chemical crosslinks was affected with the presence of the clay mineral, moreover, little or no reinforcement effect was achieved most likely to the lack of interaction with the matrix.
