Abstract

The long-tern pollution of the environment imposed by mineral oil based lubricants, has led to the renewed interest in the needs of finding alternative environmental friendly oil as lubricant. Vegetable oil is seen to be the candidate for the substitution of mineral oil based lubricant because of it properties of biodegradable, environmental friendly and renewable. The purpose of this study is to develop new bio-lubricant using Zinc Dialkyldithiophosphate (ZDDP) induced canola oil added with the addition of secondary additive of Molybdenum Dialkyl Dithiophosphate (MoDTP). The ZDDP induced canola oil was added with Owt%, 0.05wt%, O.!Owt%, 0.15wt%, 0.2 wt% of MoDTP. The newly formulated biolubricantwas tested using Ame1ican Society for Testing and Materials (ASTM) methods. The oil was tested using ASTM D6595 and heated kinematic viscometer to determine the metal content and the kinematic viscosity. The newly fo1mulated biolub1icant was also characterized using four-ball test and up1ight laser microscope to determine the coefficient of friction and wear scar diameters. Result found that the 2 wt% ZDDP with 0.05 wt% MoDTP provides the lowest kinematic viscosity value of 38.0 cStwhich was the lowest amongst the other sample. The coefficient of friction of the canola oil with 2 wt% ZDDP and 0.05 wt% MoDTP shows the lowest value which was 0.064. The lowest wear scar diameter obtainedat79.56 μm was also from the introduction of 2 wt% ZDDP and 0.05 wt% MoDTP. Found in this experiment which the composition of canola oil with 2 wt% ZDDP and 0.05 wt% MoDTP gives the most desirable results. In conclusion, the newly f01mulated bio-lubricant was successfully developed by introducing MoDTP into the ZDDP induced canola oil which fui1her enhanced it anti-wear properties.
