Title:
METAL-WORKING FLUID COMPOSITION AND PRODUCTION METHOD
Document Type and Number:
Japanese Patent JP2022098481
Kind Code:
A
Abstract:
To provide a metal-working fluid which is environmentally friendly and is effective to reduce friction caused by removing material from a surface of a work piece and dissipate heat generated by frictional contact between a tool and the work piece.SOLUTION: The disclosure relates to a biobased metal-working fluid (MWF) composition and a method for producing the same, and more particularly a metal-working fluid with biobased lubricants with improved emulsion stability. At least 50 wt.% of base oil components in an MWF concentrate is a plant-derived liquid decarboxylated rosin acid oil ("DCR"). The DCR comprises 50 to 100 wt.% of tricyclic compounds having: 18-20 carbon atoms; one or more C=C groups; an m/z (mass/charge) value of 220-280 as measured by GC-FID-MS; an oxygen content of less than 5%; and an acid value of less than 50 mg KOH/g as measured using ASTM E28-18. The resulting MWF is characterized as having comparable or good performance compared to an MWF containing only mineral oil (e.g., Group I or Group II).SELECTED DRAWING: None
