环氧树脂选择对其改性水性树脂涂料漆膜性能影响(朱海)

广州大学本科毕业论文课题名称环氧树脂选择对其改性水性树脂涂料漆膜性能影响学院化学化工学院专业化学工程与工艺（精细化工）班级名称11精细化工班学生姓名朱海学号1105200077指导老师刘晓国完成日期2015年4月8日环氧树脂选择对其改性水性树脂涂料漆膜性能影响摘要本实验选择高环氧值、低粘度的环氧树脂Der671与带羧基和双键的顺丁烯二酸酐反应制得环氧顺丁烯酸酯EA，然后EA树脂中双键与丙烯酸酯双键聚合反应合成环氧改性丙烯酸树脂。并对EA和环氧改性丙烯酸树脂的固含量，粘度，PH等性能测试，以确保反应正确进行，得到合格的环氧顺丁烯酸酯EA及环氧改性丙烯酸树脂。并以此树脂为基料制备清漆，测试性能，确保达到可实际使用的指标。喷涂，烘烤制得漆膜，测定其硬度、附着力、耐水煮性及耐碱性等性能，以此研究环氧树脂含量对水溶性改性丙烯酸树脂涂料漆膜性能的影响。得出环氧改性丙烯酸树脂的最佳配方。实验结果表明的环氧用量对环氧树脂含量对水溶性改性丙烯酸树脂涂料的附着力和硬度影响不大，但可对其耐水煮及耐碱性造成明显改变。适当的配方可制得水溶性、耐候性及力学性能都非常好的水溶性环氧改性丙烯酸树脂涂料。关键词环氧改性、水性丙烯酸树脂、漆膜性能Forthemodifiedepoxyresinwater-basedresincoatingfilmperformanceimpactABSTRACTThisexperimentselecthighepoxidevalueandlowviscosityepoxyresinDer671withcarboxylanddoublebondofmaleficanhydridereactionmadeepoxymaleficacidesterEA,thenadoublebondintheEAresinandacrylatedoublebondpolymerizationsynthesisofepoxymodifiedacrylicresin.AndtheEAandepoxymodifiedacrylicresinsolidcontent,viscosity,PHandotherperformancetesting,toensurethatthecorrectreaction,getqualifiedepoxymaleficacidesterEAandepoxymodifiedacrylicresin.Andresinmaterialsforpreparationofvarnish,performancetesting,makesuretogettotheactualuseofindicators.Spraying,bakingpaintfilmsystem,determinationofthehardness,adhesion,waterresistanceandalkaliresistance,suchasperformance,thisresearchepoxyresincontentontheinfluenceofwatersolublemodifiedacrylicresincoatingsfilmperformance.Theoptimumformulationofepoxymodifiedacrylicresin.Theexperimentalresultsshowthatthedosageofepoxyresincontentinepoxyadhesionandhardnessofthewatersolublemodifiedacrylicresincoatingeffectisnotbig,butcancauseobviouschangetothewaterresistanceandalkaliresistance.Theappropriateformulacanbeobtainedwater-soluble,weatheringresistanceandmechanicalpropertiesareverygoodwater-solubleepoxymodifiedacrylicresincoating.KeywordsEpoxyresin,water-borneacrylicresin,paintfilmperformance目录1.前言..........................................................................................................................11.1水溶性涂料的现状分析.................................................................................11.2水溶性涂料的特点.........................................................................................11.3与选题相关的国内外研究和发展概况..........................................................21.4本课题的研究目的和意义.............................................................................21.5研究方法及要达到的要求.............................................................................32.理论分析....................................................................................................................32.1水性环氧改性丙烯酸树脂合成的原料的选择.............................................32.2温度的选择.....................................................................................................42.3合成反应原理.................................................................................................42.4EA合成酸值的测定....................................................................................52.5性能测试指标.................................................................................................52.5.1水溶性环氧改性丙烯酸树脂和水溶性涂料产品测试指标..................52.5.2水溶性涂料涂膜性能指标......................................................................63.实验..........................................................................................................................73.1主要原材料和仪器、设备..............................................................................73.2配方设计.........................................................................................................83.2.1环氧酯化中间体EA合成配方..............................................................83.2.2水溶性环氧改性丙烯酸树脂合成配方..................................................83.2.2水溶性环氧改性丙烯酸树脂清漆配方..................................................93.3、实验步骤.....................................................................................................103.3.1环氧酯EA合成步骤............................................................................103.3.2水溶性环氧改性丙烯酸树脂合成........................................................103.3.3水溶性环氧改性丙烯酸树脂清漆制备................................................103.4涂膜样板制备...............................................................................................103.5试验结果........................................................................................................103.5.1环氧酯EA性能指标............................................................................113.5.2不同配方的水溶性环氧改性丙烯酸树脂性能指标............................113.5.3不同配方的水溶性环氧改性丙烯酸树脂清漆性能指标....................113.5.4不同配方的水溶性环氧改性丙烯酸树脂清漆涂膜性能指标............124.结果讨论..................................................................................................................134.1水溶性树脂和水溶性涂料产品的性能指标...............................................134.1.1不同配方的水溶性环氧改性丙烯酸树脂性能指标.............................134.1.2不同配方的水溶性环氧改性丙烯酸树脂清漆性能指标....................134.2不同配方的水溶性环氧改性丙烯酸树脂清漆涂膜性能指标...................134.2.1不同配方的水溶性环氧改性丙烯酸树脂清漆涂膜附着力.................134.2.2不同配方的水溶性环氧改性丙烯酸树脂清漆涂膜硬度.....................134.2.3不同配方的水溶性环氧改性丙烯酸树脂清漆涂膜耐水煮性能.........144.
