摘　　要：试验采用酯化法,选用乙醇作为带水剂,以十六醇、硼酸与五氧化二磷为原料,在一定的条件下反应,生成一种水解稳定性高、抗磨性能好的含磷硼酸酯润滑油添加剂。合成的最佳反应条件为十六醇、硼酸与五氧化二磷的摩尔比为7∶2∶1,反应温度为105~110℃,脱水反应4 h。用四球机测试含该添加剂的基础油的抗磨性能,结果表明试验制备的含磷硼酸添加剂能显著提高基础油的抗磨性能,且其添加剂存在一个最佳值。将所合成的含磷硼酸酯润滑油添加剂在新东北电气集团罐体车间试用,润滑效果与抗磨性能非常适宜。Phosphorus-containing borate as lubricating oil additive preparation was disscussed which had high hydrolytic stability and good abrasion resistance by boric acid and lauryl alcohol and phosphorus pentoxide,and the esterification method was adopted,ethanol was choosed as dehydrant. The optimum reaction conditions were the molar ratio of cetyl alcohol and boric acid and phosphorus pentoxide as 7∶ 2∶1,reaction temperature was 105-110 ℃,and dehydration 4 h. The anti-wear properties of the base oil containing the additive were tested with four-ball apparatus. The results showed that phosphorous borate additives could remarkably improve the antiwear properties of the base oil and additives existde an optimum value. The phosphorus-cotaining borate as lubricant additive were used in tank workshop of the New Northeast Electric Group,as a result,the lubrication effect and the anti-wear performance were very appropriate.
