Abstract
The objective of this research was to observe the effect of MBTS/ZDEC ratio on dynamic properties, curing characteristic, morphology as well as hardness and resiliency of the NR/EPDM blends prepared by curatives migration control technique. The MBTS/ZDEC ratio were 1.6/0.0; 1.5/0.1; 1.4/0.2; 1.3/0.3 and 1.2/0.4 respectively on a fixed NR/EPDM ratio of 60/40. Compounds (EPDM and NR) were prepared separately using two roll mill. The blends with binary accelerator MBTS/ZDEC showed synergistic activity which provided higher crosslink density than those of single accelerator MBTS. Reduction of ts2 and t90 as well as cure rate index (CRI) indicated the more homogeneous crosslink density distribution within the rubber phase. Scanning electron micrograph showed that the blends with binary accelerator gave smoother surface. Binary accelerator resulted higher hardness. Increasing of ZDEC raised hardness followed by reduction of the resillience property.
