Daftar Isi:
- In this study, irradiation copolymer of natural rubber latexmethyl methacrylate ( NRL-co-MMA) was added into recovery synthetic and mineral lubricant oil as samples at concentration of 0.25%, 0.70%, 1%, 3%, 5%, 7%, 10%. The viscosity index and kinematic viscosity of samples were compared to commercial lubricant oils. The results shown that viscosity index of recovery sinthetyc lubricant oil increased more than 50% at 0.25% addition of NRL-co-MMA. At similar addition of NRL-co-MMA, the viscosity index of mineral lubricant oil increased up to 11%. Pour point of samples were less than minus 36, means fulfill the Society of Automotive Engineers (SAE) standard. The total base number of lubricant samples increased significantly by NRL-co-MMA addition.Keywords: Natural Rubber Latex, Methyl Methacrylate, Radiation copolymer, Recovery sinthetic lubricant oil, Viscosity index.
