Year: 2024
Type: article
Abstract: Introduction: Mono, di, tri acetyl glycerols were obtained by esterification of technical grade glycerin with acetic acid in the presence of ion exchange resin on a laboratory scale. Toluene was used as a trawling agent. The mixture of acetyl glycerols was added with zinc oxide nanoparticles by applying ultrasound dispersion; concentrations equivalent to 0.05 were tested; 0.1;0.15; 0.2% by weight. The dispersions were subjected to four-ball tribological tests. The lubricating behavior under low load conditions was assessed through the Preventive Wear test, with measurement of the footprint diameter and the friction coefficient. The morphology of the prints was analyzed using scanning electron microscopy. The performance of the dispersions under Extreme Pressure lubrication conditions was evaluated by quantifying the welding point. The results obtained from the experimentation indicate that mono, di, tri acetyl glycerols require the addition of metal nanoparticles to improve their tribological performance with the purpose of using them in biolubricant formulations. Objective: study the behavior of mono, di, tri acetyl glycerols MDTAG in terms of tribology, mixing it with nanoparticles to improve the lubricating power. Method: The dispersions were subjected to four-ball tribology tests. The lubricating behavior was evaluated under low load conditions by applying the Preventive Wear test, the footprint diameter and the friction coefficient were measured. Results: The results obtained from the experimentation indicate that mono, di, tri acetyl glycerols require the addition of metal nanoparticles to improve their tribological performance with the purpose of using them in biolubricant formulations. Conclusions: The mixture of mono, di, tri acetyl glycerols with the addition of zinc oxide nanoparticles allows them to possibly be used as additives in biolubricant bases.
