本論文研究選用Digriumlycidyl Ether of Bisphenol A環氧樹脂(DGEBA)為基材添加酸酐硬化劑(NMA)來硬化,如果只是添加NMA來硬化其加工溫度大約在180~200℃,因此本實驗加入不同比例(1.0PHR、1.5PHR、2.0PHR、2.5PHR)的促進劑(BDMA)來加速整個硬化行為,並利用剛性震盪擺錘震動減衰儀(Rigid-body Pendulum Rheometer)測試觀察架橋硬化反應行為,而促進劑2.5PHR有較好的硬化行為,因此做為本實驗的促進劑配比。我們在140℃、150℃兩種不同的溫度下,觀察促進劑2.5PHR在剛性震盪擺錘震動減衰儀(Rigid-body Pendulum Rheometer)的硬化行為,可以得之140℃的硬化較為快速。在第一部分環氧樹脂添加鈦酸鋇的量逐漸增加可以明顯看到鈦酸鋇因為粒徑較大會有沉澱的現象,但在第二部分我們混入奈米粉末氧化鋁,在不同成分試片的截面圖中可以發現,鈦酸鋇的粉末均勻分散,因為奈米粉末氧化鋁在SEM的儀器下照射不出來,藉由EDS的分析我們可以知道加入了奈米粉末的氧化鋁減低了鈦酸鋇的沉降速度,並且提高了電氣的絕緣強度,其電容(C)及介電常數(Er)差異性不大、穩定性良好。


The thesis selected Diglycidyl Ether of Bisphenol A epoxy resin(DGEBA) as base material, curning by the addition of NMA. The curning temperature was approximately 180~200℃ while merely adding NMA; this research was to join different proportion (1.0PHR, 1.5PHR, 2.0PHR, 2.5PHR) of benzyldimethylamine (BDMA) to accelerate the entire curning process, and by implementing the test of Rigid-body Pendulum Rheometer to observe crosslinking curning response. Since the base material appeared better curning response under 2.5PHR of benzyldimethylamine, this research applied it as the proportion of benzyldimethylamine. Under two different temperatures, 140℃ and 150℃, observing the curning response with proportion 2.5PHR of benzyldimethylamine under Rigid-body Pendulum Rheometer, we discovered the curning response under 140℃ was faster.In the first part, by the gradually increasing amount of epoxy resin, we observed the particle size of BARIUM TITANATE(BaTiO3) enlarged and caused precipitation phenomenon. However, in the second part, after the mixture of nano-poder Alumina, we discovered the BARIUM TITANATE(BaTiO3) powder dispersed evenly in the sample cross-section under different ingredient. Since the nano-poder Alumina could not shown under SEM instrument, by analyzing through EDS, we were able to know that the precipitation of BARIUM TITANATE(BaTiO3) speeded down under the joint of nano-poder Alumina. Meanwhile, the intensity of insulation enhanced. Also, the differentiations of its electric capacity (C) and dielectric constant (Er) were not significant, and with constant.
