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。
In this study,glycerol trioleate(GTO)and trimethylolpropane trioleate(TMPTO)were used as raw materials to prepare waterbased 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 re⁃lease agent was lower than that of TMPTO water-based release agent,the increase of the relative content of volatile components after oxida⁃tion 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 bet⁃ter than that of TMPTO water-based release agent.In addition,the quality and oxidative stability of raw materials were the main factors af⁃fecting the oxidation degree of water-based release agent.
