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. |
