Abstract A water-soluble lubricant additive (RSOPE) was prepared by
esterification reaction using fatty acid from rubber seed oil. The RSOPE was added
into water-ethylene glycol (W-EG) solution as lubricant additive. Dispersion
stability and rheological properties were investigated. We used a four-ball
tribotester to assess the lubrication performance of W-EG based fluid with the
RSOPE additive. The stainless-steel surface was analyzed using scanning electron
microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Good dispersion
stability was observed in the RSOPE/W-EG solutions. Furthermore, nonNewtonian
fluid behavior at low shear rates and Newtonian fluid behavior at high
shear rates was exhibited. The addition of RSOPE… More >
