PCB防潮剂的合成及其性能研究摘要本文介绍了适用于PCB防护的几种防护材料，选定以丙烯酸树脂为主要成膜物质，加入溶剂、助剂等合成兼具防水、防盐雾、阻燃等性能的防潮剂。本研究的主要过程是首先选用不同玻璃化温度的丙烯酸树脂配制不含阻燃剂的防潮剂，测试其附着力、耐环境腐蚀性、电绝缘性等，然后根据测试结果调整配方，并在此基础上加入不同种类和数量的阻燃剂，测试其相关的性能，最后进行对比并得出结论。关键词：PCB丙烯酸树脂防潮剂阻燃剂ThesynthesisofdampproofingadmixtureofPCBanditsresearchofpropertiesABSTRACTThisarticledescribessomeprotectionmaterialsforPCBprotection,whichselectacrylicresinmaterialasthemainfilm-forming,addingsolvents,additivesandotherssynthesizethedampproofingadmixturepossessingpropertiesofwaterproof,anti-saltatmosphereandantiflaming,Themainprocessofthisstudyis,firstmakingupdampproofingadmixturewithoutflameretardantbyusingacrylicresinwithdifferentglasstransitiontemperature,testingpropertiesoftheadhesion,resistancetoenvironmentalcorrosion,electricalinsulation,etc.,andthenadjustingtheformulabasedontestresults,andbasedonthisaddingdifferenttypesandquantitiesofflameretardant,makingatesttoitsassociatedperformance.Finallydrawingconclusionsbycomparison.Keywords:PCBAcrylicresinDampproofingadmixtureFlameretardant目录摘要...............................................IABSTRACT..........................................II1前言..............................................11.1防潮剂的发展状况及应用领域.........................11.2防潮剂的组成.......................................11.2.1成膜物质.........................................11.2.2溶剂.............................................21.2.3助剂.............................................21.3本课题的研究.......................................31.3.1研究的目标、内容及研究意义.......................31.3.2课题研究的思路及方法.............................41.3.3本课题研究的重点.................................42实验部分..........................................52.1主要原料及设备.....................................52.2防潮剂的配方.......................................62.3性能测试...........................................72.3.1黏度的测定.......................................72.3.2附着力的测定.....................................72.3.3漆膜的耐水性.....................................82.3.4漆膜的耐油性.....................................82.3.5漆膜的耐热性.....................................92.3.6漆膜的耐盐雾腐蚀性...............................92.3.7潮态实验........................................122.3.8漆膜的阻燃性....................................123结果与讨论.......................................143.1防潮剂的黏度......................................143.2防潮剂漆膜的附着力................................143.3防潮剂漆膜的耐盐雾腐蚀性..........................163.4防潮剂漆膜的耐热性................................183.5防潮剂漆膜的耐水性................................193.6防潮剂漆膜的耐油性................................213.7防潮剂漆膜的阻燃性能..............................213.8防潮剂的潮态实验..................................223.8.1防潮剂漆膜的电绝缘性............................223.8.2防潮剂漆膜的耐湿热老化性........................284结论.............................................32参考文献..........................................33谢辞..............................................34第1页共39页编号：时间：2021年x月x日书山有路...
