样本科毕业论文（设计）涂料用防霉剂性能影响因素分析二级学院医药化工学院专业应用化学（化妆品方向）班级2012级（1）班学生姓名韦健华学号1215512134指导教师张必胜卢秀霞2016年04月15日诚信声明我声明，所呈交的毕业论文（设计）是本人在老师指导下进行的研究工作及取得的研究成果。据我查证，除了文中特别加以标注和致谢的地方外，论文（设计）中不包含其他人已经发表或撰写过的研究成果，也不包含为获得其他教育机构的学位或证书而使用过的材料。我承诺，论文（设计）中的所有内容均真实、可信。毕业论文（设计）作者（签名）：年月日涂料用防霉剂性能影响因素分析【摘要】目的：考察吡啶硫酮锌(ZPT)、异噻唑啉铜(DCOIT)、碘代丙炔基氨基甲酸酯(IPBC)三种涂料用防霉剂运用在涂料配方中和生产工艺中抗霉性能的变化，通过抗菌圈试验，选择防霉剂体系的最优配方及其比例，达到增强经济型涂料的防霉性能，延长防霉的时间的目的。方法：以量变控制法和抑菌环试验法为研究方法。先进行水性涂料配方配制；再进行霉菌的采样，分离，培养；单因素考察成膜物质、增稠剂与颗粒度改变的抑菌效果。结果：3种防霉剂中ZPT抑霉效果最好，其次为IPBC，DCOIT最差。但是ZPT在三者中的分解能力最强，防霉效果失效越快；多元复配中DCOIT和IPBC复配能起到最佳抑菌效果，复配比例为DCOIT∶IPBC=2∶3；应用到水性涂料中，成膜基料为丙烯酸乳液的防霉效果差于聚氨酯乳液；增稠剂为羟乙基纤维素比聚丙烯酸的防霉效果差；且颗粒度越小，抑菌效果越好。结论：成膜基料为50%的聚氨酯、增稠剂为0.8%的聚丙烯酸、防霉剂为0.2%的DCOIT和0.3%的IPBC复配物，并且涂料颗粒度为＜80μm制备出的水性涂料呈现最佳的防霉效果且防霉长效。【关键词】水性涂料；防霉剂；霉菌；影响因素InfluenceFactorsAnalysisofthePerformanceoftheMildew-proofAgent[Abstract]Objective:investigationofthreekindsofmildew-proofagentincludingZincPyrithione(ZPT),4,5-dichloro-2-n-octy-4-isothiazolin-3-one(DCOLT),3-iodo-2-propynyl-butyl-carbamate(IPBC)whichusedincoatingformulationandproductionprocessofantimildewproperties.Throughtheantibacterialtestring,selecttheoptimalformulaandratioamongthemildew-proofagentsystem,toenhancetheperformanceofeconomicalcoatingandprolongmoldtime.Researchmethods:researchmethodswithquantitativeandcontrolmethodandbacteriostaticringtest.Followingtheformulatomakethewater-basedcoating.Themoldsofsampling,isolation,culture.Investigationtheantibacterialeffectwiththesinglefactorofmembranematerials,thickeningagentsandgranularitychange.TheresultsshowedthattheantimoldeffectofZPTisbest,followedbyIPBC,DCOITworst.ZPThasthestrongestdecompositionability,soitloststhemouldproofeffectquickly.Inthemultivariatecompound，DCOLTandIPBCcombinationcanplaythebestinhibitoryeffectby0.2to0.3.Appliedtowater-basedcoating,thefilmformingbasicmaterialforacrylicemulsionmouldproofeffectispoorinpolyurethaneemulsion;Thickenerforhecmouldproofeffectispoorthanpolyacrylicacid.Andthesmallertheparticlesize,bacteriostaticeffectisbetter.Conclusion:filmbasefor50%0.8%ofpolyurethanethickenerofpolyacrylicacid,fungicideDCOITwith0.2%and0.3%ofIPBCcompoundwithcontent,granularityandcoatingas80μmpreparationofwaterbornecoatingsshowbestmouldproofeffectandlong-termmouldproof.[Keywords]Water-basedcoatingMildew-proofAgentMildewInfluenceFactors目录1.前言........................................................................................................11.1霉菌的种类与特点.................................................................................................11.2涂料用防霉剂分类.................................................................................................11.3无机防霉剂性质与特点........................................................................................11.3.14,5-二氯-2-正辛基-4-异噻唑啉-3-酮的性质与特点......................................21.3.2吡啶硫酮锌的性质与特点...................................................................................21.3.33-碘-2-丙炔基丁基氨基甲酸酯的性质与特点...................................................31.4研究目的与研究内容............................................................................................32.实验部分...............................................................................................52.1实验试剂................................................................................................................62.2实验仪器................................................................................................................52.3实验方法................................................................................................................62.3.1霉菌采样与培养..................................................................................................62.3.2霉菌稀释液制备..................................................................................................72.3.3防霉剂筛选..........................................................................................................72.3.4水性涂料的基础配方..........................................................................................82.3.5抑菌环试验..........................................................................................................93.实验结果与讨论.................................................................................103.1防霉剂自身药效影响对涂料防霉的影响...........................................................103.2成膜基料因素对涂料防霉的影响......................................................................113.3增稠剂因素对涂料防霉的影响..........................................................................123.4颗粒度因素对涂料防霉的影响..........................................................................134.结论......................................................................................................15参考文献..................................................................................................16致谢...........................................................................................................1811前言1.1霉菌的种类与特点内外墙上霉菌利用墙体肤层（通常指腻子层和面漆层）中可利用的碳源、氮源，以菌群的方式寄生于墙体表面，并且进行大量繁殖的真菌群落，通常呈现出黑毛、绿毛、红毛、黄毛等形态，其中包括黑曲霉、黄曲霉、球毛壳霉、木霉、宛氏拟青
