摘要:本研究以甘油三油酸酯（GTO）和三羟甲基丙烷三油酸酯（TMPTO）为原料分别制备水性剥离剂，通过酸价、过氧化值和气相色谱-质谱联用技术对其氧化稳定性进行研究。结果表明，在相同条件下，GTO水性剥离剂的氧化程度低于TMPTO水性剥离剂；氧化后GTO水性剥离剂的挥发性成分相对含量增长量（124.5）显著小于TMPTO水性剥离剂的挥发性成分相对含量增长量（613.9），其中醛类（占比72%~84%）是最主要的挥发性成分。因此，GTO水性剥离剂的氧化稳定性优于TMPTO水性剥离剂。此外，原料的品质和氧化稳定性是影响水性剥离剂氧化程度的主要因素。

Abstract:In this study， glycerol trioleate （GTO） and trimethylolpropane trioleate （TMPTO） were used as raw materials to prepare water-based release agents respectively， the oxidative stabilities of these two water-based release agents were studied by acid value， peroxide value and gas chromatography-mass spectrometry. The results showed that under the same condition， the oxidation degree of GTO water-based release agent was lower than that of TMPTO water-based release agent， the increase of the relative content of volatile components after oxidation was significantly less of GTO water-based release agent （124.5） than that of TMPTO water-based release agent （613.9）， and aldehydes （covering 72%~84%） were the most major volatile components. Therefore， the oxidative stability of GTO water-based release agent was better than that of TMPTO water-based release agent. In addition， the quality and oxidative stability of raw materials were the main factors affecting the oxidation degree of water-based release agent.
