Abstract

Rubber materials are widely used in human daily life. Most common usage of rubber material is mostly in tires, construction and automotive industry. The main components of rubber compounds are rubber, reinforcing fillers and processing oils. One of the main purposes of processing oils is to decrease the viscosity and to raise the quality of rubber compounds. The aromatic oils which containing polycyclic aromatic hydrocarbon is widely used in producing many type of rubber compound due to their compatibility to unsaturated materials. However, aromatic oils have carcinogenic potential and tend to be replaced with other environmentally friendly option. Therefore, this study presents the potential of chemically treated waste cooking oil (WCO) as processing oil for rubber compound production. Waste management issues of frying or waste cooking oil have led greatly to severe environmental problems. Moreover, around three billion liters of cooking oil consumed in Malaysia yearly which about 30% of WCO accessible for biodiesel production or disposal to environment. In this study the waste cooking oil was modified through the transesterification process to be used as the processing oil for rubber compound. The cure characteristic of the rubber compound and the mechanical properties rubber vulcanization were measured and compared than commercial processing oil based rubber. The resulted NR compounds processed by using the WCO as PO at varying collect (0, 10, 20, 30 grams) has shown promising and comparable cure characteristic, physical and mechanical performances than commercial parafinic as processing oil added to industrial NR compound. This study was significant as WCO used in this study, able to replace parafinic oil as sustainable candidate of processing oil for manufacturing of rubber compound.
