摘要

本研究是以自行合成之多胺磷(月青)化合物N3P3(OC6H5)n(p-OC6H4NH2)6-n n=3,4,5(PN)依不同當量比與三種環氧樹脂混合，來探討不同的環氧樹脂在各系統中之硬化反應性及難燃性。
我們將自行合成矽環氧樹脂（SC）及所購得矽環氧樹脂（MC）與磷氮環難燃劑(PN)依當量比混合，再分別以熱重分析儀（TGA）、示差掃瞄卡計（DSC）、紅外線光譜（FTIR），TGA/FTIR、LOI來測試耐燃、耐熱性。由DSC圖顯示，硬化劑的反應性為DDM>PN，各環氧樹脂之反應性依序為Epon 828>SC>MC。由TGA及LOI的結果顯示，三種組成的環氧樹脂與純的環氧樹脂（Epon828）比較下，皆有較低之熱裂解溫度，並有較高之高溫熱穩定性。同時其高含磷量提高殘渣量說明了合成之磷(月青)環環氧樹脂具有較好之難燃性質。
探討含磷之難燃劑對硬化物的耐燃性是否有提升，我們發現當磷含量增加時，硬化物在600℃時之殘渣量也有提升，在LOI的測試也是也所改進。

Abstract
This study aims at developing cyclotriphosphazene containing compounds for flame retardant polymer materials.In the first, a novel flame-retardant N3P3(OC6H5)n(p-OC6H4NH2)n-6, n=3,4,5(PN) was synthesized, then cured with Epon828、SC and MC. We also successful synthesized siloxane-type epoxy resin(SC).
Compared with Epon828, SC and MC, the higher reactivity from DSC were in the order of Epon828>SC>MC. Compared with PN and DDM, we found the order of the reactivity was DDM>PN. From TGA and LOI we can find when phsophaezene increased, the T5% moved low temperature and the char yield increased. It showed that when we had high phosphazene in epoxy resins, the epoxy resins had the high thermal stability and high fire retardancy.
The curing reactions of the epoxy resins were studied by differential scanning calorimetry(DSC), thermal properties of analysis(TGA) and the flame retardancies were estimated by measurement of the limited oxgen index(LOI).
