Abstract
Reclaimed rubber filled PP/ENR blend is an emerging new thermoplastic elastomer material. The effect of blend ratio, dynamic vulcanization, and crosslinking agent on the properties of polypropylene (PP), epoxidised natural rubber (ENR) and reclaimed rubber (RR) blends were investigated. Dynamic vulcanization was prepared using stearic acid and zinc oxide (ZnO) as additional crosslinking chemicals followed by sulphur curing. Design of experiment (DOE) was conceived and optimized response surface methodology (RSM). Thermoplastic elastomer compound was prepared by melt compounding and compression molding processes. Blends were prepared by melt mixing in an internal mixer, Haake Rheomix of temperature and rotor speed of 180ºC and 60 rpm, respectively. Reclaimed rubber composition was introduced in 0, 25 and 50 percentage. Effect of reclaimed rubber ratio, TMPTA and Iragnox1010 as stabilizer and binder to the cure characteristics and mechanical properties of thermoplastic elastomeric compounding was investigated. The characteristics and mechanical properties of the compound had been determined using tensile, Izod impact, and hardness tests. Thermoplastic elastomers filled 50% of RR showed highest tensile strength and energy absorption mechanism of 7.909MPa and 3 J/m. The microstructure of specimen observed using scanning electron microscopy (SEM) showed good miscibility between rubber and plastic due to the presence of RR. As expected, the tensile properties and thermal stability increase with the increases RR content due to superior characteristics of this material.
