Abstract

This study is to develop a new formulated bio-lubricant. The development of bio-lubricant which is biodegradable, non-toxic and renewable resources are desired since the existing mineral based lubricant are of non-renewable sources and prone to environmental issues. With the increasing concerns of environmental issues, palm oil has been use to replaced mineral oil as lubricant. Zinc Dibutyloctyl Dithiophosphate (ZnBuDP) and Molybdenum Dialkyl Dithiophosphate (MoDTP) was introduced into palm oil to improve the tribological properties in order to make it comparable with commercialized mineral based lubricant. The sample prepared will be added with constant concentration of ZDDP at 2wt% while the concentration of MoDTP varies from O.OOwt% to 0.20wt% with interval 0.05wt% into palm oil and the total weight for each sample bottle is 200g. The samples were tested in accordance to the American Society for Testing and Material (ASTM) method. ASTM 06595 was used in sample testing in determining the metal content of samples collected by Rotating Disc Electrode Atomic Emission Spectroscopy (RDE-AES). ASTM 04712 was used in sample characterization to characterize the coefficient friction and wear scar diameter by four ball tester and upright laser microscope respectively. The lowest coefficient of friction was recorded at 0.065 while the lowest wear scar diameter obtained at 79.14 um. Result found the desirable results recorded was at concentration of 2 wt% of ZnBuDP and 0.05 wt% of MoDTP. In conclusion, the combination of ZnBuDP and MoDTP induced into palm oil was successfully developed as newly formulated biolubricant.
