Technical Abstract: Emulsion based lubricants are used widely in metalworking, mining, fire-resistant hydraulic applications, and more, due to their low cost high performance. Key emulsification factors, such as appearance, particle size distribution and stability, are very important to lubricant applications. Water based metalworking fluids traditionally employ mineral oil emulsions, however, vegetable oil use is gaining in popularity. It has been shown that the chemical modification of vegetable oils can improve physical properties in base oils, such as surface adsorption, oxidative stability, and viscosity. However, it has not yet been reported if these oils are suitable for emulsification based lubrication. This presentation will show the emulsion stability of several biobased lubricant formulations where both traditional alcohol ethoxylate surfactants and biobased glyceride surfactants were used. The friction and wear reducing performance of some of these emulsions will also be reported.
