摘　　要：为了满足航空发动机日益严苛的工况要求,通过向某烃类航空润滑油中添加不同量的添加剂,制备一系列改性航空润滑油;采用氧化工况模拟标准装置,分别测试不同氧化时间、不同氧化温度下,改性油样及原油样的黏度、酸值、倾点、抗磨性能、承载能力、起始氧化温度(IOT)、氧化诱导期(OIT)等性能指标,评价改性油样的综合性能。实验结果表明:氧化温度越高,改性油样颜色加深速度越缓慢,即抑制油品氧化效果越明显;相同氧化条件下,改性油样与原油样相比,酸值增速较低,即改性后油样能有效抑制酸值升高,改善了油品的抗腐蚀性能,同时改性对油品的黏度、倾点未产生不良影响;油样改性后未对抗磨性能产生不良影响,但有可能导致油品的承载能力下降,不过影响在可控范围内;油样改性后IOT、OIT值提升,氧化安定性明显改善。In order to meet the increasingly severe working conditions of aero-engines,a series of modified aviation lubricating oils were prepared by adding different amounts of additives to a certain hydrocarbon aviation lubricating oil.The performance indicators of these modified oil samples and the original oil sample,including viscosity,acid value,pour point,antiwear properties,load carrying capacity,initial oxidation temperature(IOT),oxidation induction period(OIT)were tested at different oxidation time and oxidation temperature by the oxidation condition simulation device,and the comprehensive properties of the modified oil samples were evaluated.The results show that the higher the oxidation temperature,the slower the color deepening speed of the modified oil,that is,the more obvious the effect of inhibiting the oxidation of the oil.Compared with the original oil sample,the acid value growth rate of these modified oil samples is lower under the same oxidation conditions,indicating that the modified oil sample can effectively suppress the increase in acid value and improve the corrosion resistance of the oil product.The modification has no adverse effect on the viscosity,pour point and anti-wear properties of the oil,however,it may lead to a decrease in the bearing capacity of the oil,but the impact is within a controllable range.After oil sample modification,the IOT and OIT values increase,and the oxidation stability is significantly improved.
