Effect of nanoparticles on Tribological Study of Eco-Friendly Grease Made with Soybean Oil, Beeswax and Acacia Gum

The lubricating grease is simply a lubricating fluid which is gelled with a thickening agent such that the lubricant can be retained more readily in the specific required area. It is made of two primary ingredients: base oils and thickeners. Various performance additives are blended frequently to grease to tailor their characteristics. The grease used in industries is made of mineral oil which is non-renewable, non-biodegradable, toxic, bio-accumulative, and hence environmentally unfriendly. A potential, sustainable and economical eco-friendly alternative to harmful petroleum-based lubricants is a big challenge for the 21st-century lubricant industry. The present study explores, for the very first time, grease produced from all natural, ecofriendly material such as Soybean oil (SO), Beeswax (BW) and Acacia gum (AG). Various samples are prepared by varying the components ratios. Application of grease depends on the physiological properties of the grease. This paper mainly focuses on properties like cone penetration, NGLI Grade, drop point, Wear Test. The tests performed for evaluating the properties are Cone penetration (ASTM-D 217-2021-a), NLGI grade (ASTM-D 217-2020), Drop point (ASTM-D -2265-2020) and Wear preventive Characteristics (ASTM D2266).
