摘要

藉由DGEBA（Diglycidyl Ether of Bisphenol-A）環氧樹脂與Novolac酚醛樹脂在120℃熱熔融混拌過程，製備出DGEBA環氧改質酚醛樹脂複合材料（EP-PF）。再經由六甲烯基四胺（Hexamine）交聯劑的熱固化作用後，形成一種具有良好的機械強度及疏水性能的樹脂複合材料。從各項分析結果的顯示，隨著環氧樹脂含量增加，在FTIR光譜吸收峰1040cm-1的C-O-C基團逐漸增長，在1361cm-1 O-H基有逐漸消失及變窄的趨勢，因此可顯示環氧樹脂與酚醛樹脂產生醚化鍵結作用。在DSC及TGA熱分析方面，環氧樹脂含量增加有逐漸縮小交聯固化反應，以及降低熱裂解溫度，但是在機械強度及疏水性能有明顯的提高。

In this study, Diglycidyl Ether of Bisphenol-A (DGEBA epoxy) modified phenolic resin composite (EP-PF) was prepared by using DGEBA epoxy mix with phenolic resin at 120℃. Furthermore, it was formed polymeric composite with an excellent mechanical strength and hydrophobic properties by reacting with hexamine at 180℃. From the results of investigation, with adding DGEBA epoxy into phenolic resin, the peak at 1040cm-1(C-O-C) becomes long gradually, and the peak at 1361cm-1(O-H) becomes short gradually for FTIR. It can be indicated that DGEBA epoxy reacted with phenolic resin to form chemical linkages. On the other hand, although the reaction of cross-linking and thermo-degradation decreased with adding DGEBA epoxy, the mechanical strength and hydrophobic properties of the composite was enhanced significantly.
