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.
