PENGEMBANGAN PELUMAS RAMAH LINGKUNGAN DENGAN ESTER BORAT
Abstract: This paper reports
an attempt to improve the performance of environmentally friendly bio-based
lube oil prepared from glycerol and oleic acid. Four variant of boric acid
esters, fortified with 2,5dimercapto-1,3,4-thiadiazol, aromatic amine
antioxidant, and benzotriazol were used as additives. The oxidation &
corrosion test was carried out using the bulk test at 150oC for 24 h. Steel
& copper specimens weight losses and kinematic viscosity increase (measured
at 40oC and 100oC according to ASTM D-445) were used to measure the effect of
formulation to the corrosiveness and oxidation stability of the oil,
respectively. Experimental results indicated that nitrogen-containing boric
acid esters showed better performance in terms of oxidation stability
improvement. Slight increases in corrosiveness were shown for all additive
systems. Phenyl-1-naphtylamine showed better performance than diphenylamine
antioxidant.
