Abstract

Elastomer compound based on NR/BR was prepared using different kinds of nano-ZnO and ZnO. The effect of zinc oxide as an activator of sulfur cure on the mechanical and morphological properties of the compound was studied. The result of the mechanical properties showed that the tensile strength, elongation-at-break, resilience, and abrasion resistance of the compound prepared by ZnO (4 phr) are equal to the compounds using nano-ZnO (Iran, 1 phr) and nano-Zno (China, 2 phr). The cure time of the compound with nano-Zno is less than that of the compound using ZnO while the scorch time of those compounds is the same. The SEM of the samples showed that the particle size of nano-ZnO (Iran) is smaller than that of ZnO and nano-Zno (China) and also uniformly dispersed.
