Tribo-chemical Properties and Synthesis on Cerium Dodecoxylborate
Abstract: The borax is the reaction of orthoboric acid and sodium hydroxide,The cerium dodecoxyborate is the reaction of borax,cerium nitrate,butyl alcohol and dodecanol under the xylene system. The better reaction condition is when the mole ratio of cerium nitrate and borax is 2:3, the esterification reaction time is 0.5h, the reaction temperature is 130℃,the transesterification reaction time is 0.5h and the most prolific rate of the product is 84.01%.It’s analyszed on cerium dodecoxyborate with IR . On the four ball machine, it’s shown that antiwear and antifriction characteristic were determined on cerium dodecoxyborate added to base oil,on which properties the addition of cerium dodecoxyborate were investigated. It’s shown that wear the better on results,when the content of cerium dodecoxyborate is 1.5%(wt%). It’s determined the largest non-card bite load PB of base oil, adding 1.5%(wt%) of cerium dodecoxyborate in the base oil and adding the T202's base oil, on results it’s shown that the base oil after adding T202,its PB is maximum. Finally, it’s determined that tribo-chemical characteristic about the compound of cerium dodecoxyborate synergied with T202, the friction and wear performance impact on these two adding amount of base oil.It’s shown that the anti-wear of lubricating oil gains its better effects on results,when add 1.5%(wt%) of cerium dodecoxyborate and add 1%(wt%) of T202 synergied.
