Abstract

This paper is to study the synthesis of Sn-benzotriazole (Sn-BTA) composite nanooil by chemical reduction and its　tribological properties. The Sn-BTA composite nanoparticles are produced through the reaction of tin (II) 2-ethylhexanoate, 1, 10-phenanthroline, sodium borohydride and BTA in anhydrous methanol solution. BTA functions as stabilizer of Sn nanoparticles and protector of anti-oxidation of Sn nanoparticles in various concentrations. Tribological experiments are conducted by using the pin-on-disk tester to observe the wear scar diameter, friction coefficient, and morphology of worn surface. In order to find out new green oil, investigation of the effects of epoxidized soybean oil for tribological characteristics is made. Their anti-wear and anti-friction performances　are found. Finally, TEM, OM, SEM and EDX are used to interpret the possible lubricating mechanisms of the anti- friction and the anti-wear functions. The test results show that the Sn-BTA nanoparticle used as an additive in liquid paraffin oil and epoxidized soybean oil at an appropriate concentration exhibit better tribological properties than those of pure paraffin oil. Compared with the pure liquid paraffin oil, the friction coefficient of the Sn-BTAadded paraffin oil is decreased by approximately 36 %, and compared with the pure liquid epoxidized soybean oil, the friction coefficient of the Sn-BTA added epoxidized soybean oil was decreased by approximately 31 %, with an additive concentration of 0.15 wt.%.
