A NOVEL BIO ECO CUTTING OIL FORMULATION USING AZADIRACHTA INDICA SEEDS

摘要

The present invention reveals a simplified, economical, novel, biodegradable process for preparing a complete biodegradable metal cutting bio eco emulsion. The formulation comprises one bio oil component, Triethanolamine and a preservative like Methyl paraben and Propyl Paraben. The emulsion concentrate is prepared by incorporating Azadirachta indica seed milk, triethanolamine and preservatives in a definite proportions and subjected for mechanical stirring so as to get uniform bioconcentrated homogenate which was further diluted with water in 2 different proportions is 5: 95 and 10: 90. The emulsion concentrate and diluted emulsions were subjected for various evaluation parameters like pH measurement, stability, and Iron Chip corrosion test and stability studies. The results reveal that formulation that FO 64 displayed unique stability and passed all BIS Specification Tests. A conclusion was drawn that this eco bio cutting oil can serve as complete biodegradable cutting oil which can be widely used as a lubricant while cutting the metal in various small scale and large scale industries.
