Abstract

Oil resistant o-rings on the basis of Acrylonitrile butadiene rubber (NBR) reinforced by Nanoclay were produced via a traditional industrial method in accordance with aviation standard, AMS 7272. The production of Nanocomposites comprised the compounding of nanocomposite with optimum mechanical properties and minimum contents of used carbon black and Nanoclay, design and manufacturing of the required mold and finally compression molding of the oring. Mechanical and morphological properties of NBR/Nanoclay compounds were optimized by introduction of proper contents of a Compatibilizer containing a mixture of resorcinol and hexamethylene tetramine through using a master batch production method. The prepared Nanocomposites were characterized using X-ray diffraction (XRD) analysis, curing measurements and tensile test analysis. The XRD analysis showed that the Compatibilizer facilitates the intercalation of Nanoclay silicate layers with the rubber chains which leads to the increase of their basal spacing. The cure characteristics of the Nanocomposites showed a decrease of scorch time and increase the cure rate index with the Nanoclay loadings. Furthermore, the minimum scorch time and maximum cure rate index could be achieved through using the appropriate content of Compatibilizer. The results exhibit that the Nanocomposites containing the Compatibilizer have higher mechanical properties especially at higher deformations compared to the corresponding uncompatibilized Nanocomposites.
