Preparation of lanthanum borate dodecyloxy and friction characteristics
Abstract ：In this experiment, lanthanum borate dodecyloxy was synthesized by boric acid, lanthanum nitrate, sodium hydroxide, butanol, petroleum ether. The optimum reaction conditions are: lanthanum nitrate molar ratio of 1:1.58 borax, the reaction temperature was 125 degrees Celsius. Using the infrared spectrometer product, and in the ring - pieces type friction and wear tester and four ball, determinate of Lanthanum borate dodecyloxy added to base oil and the friction and wear properties after the addition of Lanthanum borate dodecyloxy on these properties were investigated, results showed that when the content of Lanthanum borate dodecyloxy is 1.5%(wt%),wear the best. Determine the largest non-card bite load PB of base oil, adding 1.5%(wt%) of Lanthanum borate dodecyloxy in the base oil and adding the T202's base oil, the results show that the base oil after adding T202,its PB is maximum. Finally, determine the friction chemical about the compound of Lanthanum borate dodecyloxy and T202 and the friction and wear performance impact of these two adding amount of base oil, the results show that when add 1.5%(wt%) of Lanthanum borate dodecyloxy and add 1 %(wt%) of T202 compound, the anti-wear of lubricating oil gains its best effects.
