摘要

台灣地區每年約生成9000萬支廢日光燈管，所造成的廢日光燈螢光粉估計675公噸。廢棄的日光燈螢光粉中主要含有汞的有害物質，假如沒妥善回收處理，將會污染生活環境並危害健康。目前螢光粉除了以無害化後掩埋處理外，現今回收處置仍是採集中儲存，若能找到螢光粉再利用的機會，例如運用在下水道之管材、道路之鋪設中，即可化解螢光粉處理處置問題。本研究以廢棄回收螢光粉、水泥及環氧樹脂製成樹脂混凝土。再利用單軸抗壓機、熱示差掃描分析儀、傅立葉紅外線光譜儀、拉曼光譜儀、原子力顯微鏡及元素分析儀探討合成材料之特性，最後該樹脂混凝土的毒性特性萃取液係利用感應耦合電漿原子發射光譜儀分析螢光粉中所含之重金屬及有機物溶出情形。結果顯示抗壓強度最強之配比為螢光粉比例67 ％，最大抗壓強度為902 kg/cm2。從耐熱性來看的話螢光粉比例佔40 ％是最佳使用比例。此外當螢光粉比例增加，亦使得螢光粉樹脂混凝土的表面特性變成越硬，符合抗壓強度測試結果，最後所得混凝土中各重金屬的溶出值皆符合環保署法規標準，因此經前處理螢光粉製備成樹脂混凝土是可行的。

In Taiwan the spent lighting lamps has been expected about 90 million per year, and it will generate near 675 ton per year recycled phosphor powder. The recycled phosphor powder contains mercury and needs to be properly treated, in order to avoid the pollution of environment and health danger. Currently it is treated by dispose landfilling after detoxification or centric storage. If we can find new recycle mode for phosphor powders, for example, application on the preparation of sewage tube and building roadway, it would be helpful for treating phosphor powders.
This study use recycle phosphor powders, cement and epoxy resin to prepar plastic concrete. The synthesized composites were charactered by unconfined compressive strength tester, differential scanning calorimetry, Fourier transform infrared, Raman spectroscopy, atomic force microscopy, and elemental analyzer. In addition the induced couple plasma was used to analyze the concentrations of ions in leachate of the concrete. In the case of the prepared concrete with a ratio of phosphor powder 67 %, it shows the highest single-axial compression strength of 902 kg/cm2. The best ratio of added phosphor is commanded to be 40 % basing on the thermal property. As the content of phosphor powder in phosphor-containing polymeric concrete is increases, the concrete shows a harder surface. This observation was consisted with the single-axial compression strength data. The results of induced couple analysis of synthetic concrete is far below the regulatory standard of Taiwan EPA, therefore it is feasible for de-mercury phosphor powder to the manufacture of plastic concrete.
