Fundamental Studies on Cure Characteristics and Mechanical Properties of Nanocomposites Based on Epoxidized Natural Rubber (ENR-30) and Montmorillonite Clay

Abstract:

The present study focused on investigating the cure characteristics and mechanical properties of nanocomposites based on epoxidized natural rubber with 30 mol% epoxide (ENR-30)/nanoclay. ENR-30 based nanocomposites were prepared by melt compounding in an internal mixer and cured using a conventional sulphuric system. Two types of nanoclays were used in this study, sodium montmorillonite (Na-MMT) clay and Na-MMT that had been modified with octadecylamine, also referred to as OC-MMT. Overall results show that OC-MMT was more efficient in enhancing the mechanical properties of the ENR-30 nanocomposite than Na-MMT. This was probably attributed to the higher interlayer distance of OC-MMT, which was confirmed by X-ray diffraction results. The incorporation of OC-MMT into ENR-30 led to an increase in both the maximum torque (M_H) and torque difference (M_H-M_L), which suggested an increase in the stiffness and crosslink density of the nanocomposite, respectively. A pronounced improvement in the tensile strength of the ENR-30/OC-MMT nanocomposite as compared to the unfilled ENR-30 was observed at 5 phr of OC-MMT, which appeared to be an optimum loading level. However, a gradual reduction in the elongation at break was observed with increasing OC-MMT loading.
