ABSTRACT
Lubrication is used to reduce friction so that the surface of the object does not wear out. Currently, the raw material for making lubricants is mineral oil. The continuous use of mineral oil will have a negative impact on the environment because it is toxic and non-biodegradable. Therefore, renewable lubricants that are safe for the environment are needed, namely, biolubricants. Biolubricants are produced from vegetable oils derived from plants such as palm oil, coconut, candlenut, and so on. Palm oil is a vegetable oil that is produced in large quantities in Indonesia. However, pure palm oil (CPO) cannot be directly used as a lubricant because of its low oxidation stability. To improve the oxidation stability of palm oil is by transesterification which will produce synthetic esters-of trimethylpropane palm oil (TMP). In this study, the synthetic ester of palm oil-TMP was used as base oil with the addition of nanocellulose nata de coco additives (0.6%wt) and span 60 which were varied (0.6, 0.9, and 1.2%wt). Fourball tribotester was used to determine the lubrication performance of the lubricant made using ASTM D-4172 standard. The results showed that sample A4 with nanocelluse NDC (0.6%wt) and span 60 (0.6%wt) had the best dispersion stability and the highest lubricant viscosity value compared to sample A5 (0.9%wt) and sample A6 (1.2%wt). The coefficient of friction (COF) test results showed that sample A4 produced the best COF value of 0.05843 with a decrease of about 25,6% compared to pure TMP ester. Meanwhile, sample A5 and sample A6 produced COF values of 0.06264 and 0.06639. It can be concluded that the proper addition of nanocellulose NDC and span 60 can improve lubrication performance.
Keywords: palm oil esters-TMP, nanocellulose NDC, span 60, fourball
