Abstract
This invention is a composition of an ester resulting from the reaction of an oligomer of ethylene oxide in presence or a catalyst, with fatty acids. The resulting water based metal working fluid additive is useful as it imparts property of stable micro-emulsion and helps improving the wear life, coefficient of friction and other tribological properties among other uses.
Claims15
Stable micro emulsion based metal working fluid composition comprising reaction products from a reaction of fatty acid ranging from 26.0-29% w/w with an oligomer of ethylene oxide ranging from 56.0-58% w/w in the presence of water, a promoter and a catalyst, wherein the said composition is readily biodegradable and exhibits self-emulsifying property.
A method of use of a stable micro emulsion based metal working fluid composition as claimed in any one of the preceding claims as a lubricant between interacting metal surfaces including at least one step of rolling, drawing, stamping, cutting, bending and compressing.
