Abstract
The main purpose of this project was study the curing characteristics, tensile properties, morphological, swelling properties and magnetic properties of carbonyl iron filled waste glove natural rubber/ natural rubber blend. This project consists of two series of compounding where the first series of studies involve effect of carbonyl iron loading at 10 phr, 15 phr, 30 phr ,45 phr, 60 phr, and 75 phr carbonyl iron loading on properties of wNRG/NR blends. The second series involved effect of hybrid carbon black/carbonyl iron system with loading at 10/60 phr, 20/60 phr and 30/60 phr filled wNRG/NR blends. Carbonyl iron loading at 60 phr act as control sample due to high magnetic properties. For curing characteristics in first series, there was decreased in cure time and torque difference but increased in scorch time as increasing carbonyl iron loading filled wNRG/NR blend. It was found that the tensile strength and elongation at break decreased as increasing carbonyl iron loading on composites. For swelling percentage is decreases but increases in magnetic strength as increasing carbonyl iron loading on composites. Meanwhile, second series decreased in cure time and scorch time but increased in torque difference with increasing of carbon black loading. The tensile strength and elongation at break at 10 phr indicated optimum filler loading of this composite. As well as swelling properties, the toluene uptake increased as increasing carbon black loading. Magnetic properties decreased with increasing carbon black loading on composites.
