摘要/Abstract

摘要： 利用Dry-TOST试验考察含不同抗氧剂的涡轮机油样品的氧化寿命和油泥沉积趋势，并通过傅里叶变换红外光谱（FT-IR）、X射线能谱（EDS）和裂解气相色谱-质谱联用法（PY-GC-MS）分析了沉积油泥的成分，探究添加不同抗氧剂油品的油泥来源。结果表明：与烷基化二苯胺相比，高温下N-苯基-α-萘胺的抗氧化性能更强；经氧化后，添加单一抗氧剂（烷基化二苯胺或N-苯基-α-萘胺）的油品均产生较多油泥，但油泥的来源不同；添加烷基化二苯胺的涡轮机油的油泥主要来自于基础油的氧化产物，而添加N-苯基-α-萘胺的涡轮机油的油泥主要来自抗氧剂的反应产物。

Abstract: The oxidation life and sludge deposition trend of turbine oil with different anti-oxidants were investigated by Dry-TOST tests, and the composition of the sludge was analyzed by Fourier transform infrared spectrum (FT-IR), X-ray energy dispersive spectrometry (EDS) and pyrolysis gas chromatograph-mass spectra (PY-GC-MS) to explore the source of the sludge with different anti-oxidants. The results show that N-phenyl-α-naphthylamine has better anti-oxidating performance than alkylated diphenylamine at high temperatures, and the oil added with single anti-oxidant (alkylated diphenylamine or N-phenyl-α-naphthylamine) produces more sludge, but the source of sludge is different. The sludge of turbine oil with alkylated diphenylamine mainly comes from the oxidation product of base oil, while the sludge of turbine oil with N-phenyl-α-naphthylamine mainly comes from the reaction product of anti-oxidant.

Key words: turbine oil, anti-oxidant, sludge, alkylated diphenylamine, N-phenyl-α-naphthylamine
