【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。
[Abstract]:The esterification method was used and ethanol was selected as a water carrying agent with sixteen alcohol, boric acid and phosphorus pentoxide as raw materials. Under certain conditions, a high hydrolysis stability and good antiwear property of boric acid ester lubricating oil additive was produced. The optimum reaction condition was sixteen alcohol, and the molar ratio of boric acid to phosphorus pentoxide was 7: 2: 1. The reaction temperature is 105~110 C, and the dehydration reaction 4 h. is used to test the antiwear properties of the base oil containing the additive by four ball machines. The results show that the phosphorus containing boric acid additive can significantly improve the anti-wear performance of the base oil, and the additive has a best value. The trial of the tank tank workshop is very suitable for lubricating effect and antiwear performance.
