Abstract:
Bio-grease is a renewable, non-toxic, and environmentally friendly lubricant. Unlike traditional petroleum-based greases, it is formulated using plant-based oils that degrade more easily, reducing harm to ecosystems and wildlife if leaked or disposed of. The characteristics of our in-house made palm oil-based bio-grease comply with the Thai Industrial Standard (TIS) number 713-2541, making it suitable for general use. It is a lithium grease, with palm oil as the main component. Palm oil, containing about 50% unsaturated fatty acids, is more prone to oxidation than mineral or synthetic oils with higher saturated hydrocarbon content. Oxidation degrades the grease, forming acids, sludge, and contaminants that reduce lubrication efficiency. To improve the oxidation resistance of bio-greases, antioxidants are added to delay the oxidation process and extend the service life of grease. The 2,2'-Methylenebis(6-tert-butyl-4-methylphenol) (MBMP) and N,N´-Diphenyl-1,4-phenylenediamine (DPPD) were studied for their effectiveness in bio-grease by measuring Onset Oxidation Temperature (OOT) using Differential Scanning Calorimetry. The OOT results for grease blends showed: DPPD (202°C) > MBMP (184°C) > No antioxidant (156°C), indicating better performance from the amine antioxidant. The addition of antioxidants slightly altered grease consistency, measured by the spread method using the SKF grease test kit. The spread diameter of the grease with DPPD was 20.3 mm, compared to 18.5 mm for the greases with MBMP and no antioxidants, indicating that DPPD softened the grease. While antioxidants improve oxidation resistance, balancing their effects on other properties is crucial to ensure the grease performs optimally in its intended application.
