含磷聚酯/活性貝殼粉複合材料合成與性質之研究

本研究藉由分別添加不同含量之自製的活性貝殼粉（Activated Heavy Shell,AHS）與阻燃劑2-羧基乙基（苯基）次磷酸（2-Carboxyethyl（Phenylphosphinic）acid ,CEPPA）和雙-2-羥基乙基對苯二甲酸酯（Bis-2-Hydroxylethyl Terephthalate，BHET）、乙二醇（Ethylene Glycol，EG），聚合成含磷聚酯/活性貝殼粉複合材料。本研究之實驗（I）是先將家庭廢棄物-貝殼，洗淨、磨碎而得到貝殼粉，將硬酯酸溶解於乙醇中，後緩緩加入貝殼粉攪拌分散，完成貝殼粉之物理改質(活性貝殼粉)。再藉由添加不同比例之活性貝殼粉，利用原位聚合法，製備出PET/活性貝殼粉複合材料。本研究之實驗（II）是藉由分別添加不同比例之CEPPA，利用原位聚合法，製備出PET/CEPPA複合材料。本研究之實驗（III）是藉由添加不同比例的活性貝殼粉和固定比例的CEPPA，利用原位聚合法，製備出PET/活性貝殼粉/CEPPA複合材料；對實驗（I）、（II）及（III）之複合材料進行檢測，並且觀察其機械性質、熱性質及阻燃性之變化。在PET/活性貝殼粉、PET/CEPPA及PET/活性貝殼粉/CEPPA複合材料之結構分析中，以傅立葉紅外光譜儀（FT-IR）檢測其化學結構，發現添加活性貝殼粉體以及阻燃劑並未出現與純聚酯不同之官能基特徵峰或是造成偏移現象。機械性質方面，以拉伸測試評估材料的平均斷裂延伸率、平均最大拉伸應力。由掃描式電子顯微鏡（SEM）觀察PET/活性貝殼粉/CEPPA之表面型態與分散狀況，且用能量分散光譜儀（EDS）對其進行元素分析。由TGA分析PET/活性貝殼粉/CEPPA複合材料之熱重損失與熱裂解溫度，及以DSC分析其吸熱與放熱時間軸，並觀察PET/活性貝殼粉/CEPPA複合材料加熱過程中Tc和Tm之變化。最後經由限氧指數(L.O.I)測試以了解PET/活性貝殼粉/CEPPA複合材料之阻燃性質及燃燒型態。

In this study, Activated Heavy Shell or fire-retardant (2-Carboxyethyl (Phenylphosphinic) Acid, CEPPA)were added during the polymerization of PET in various amounts. Bis-2-Hydroxylethyl Terephthalate (BHET), Ethylene Glycol (EG), Activated Heavy Shell and CEPPA were adopted to synthesize polyester, thus to provide multi-functions to the polyesters; the research is then devided into three parts, which is shown in the following paragraphs. Part (I), Conduct PET(Composive material of Activated Heavy Shell) from clamshell; In order to produce Polyethylene terephthalate(PET) the following procedure is required: 1. Grinding the clamshells into powder-like particles after cleaning and degreasing. 2. Adding in the shell powder to a Stearic acid-ethanol solution. 3. Stiring the solution with a steady rate untill the shell particles are evenly-distributed whin the solution. Eventually, adding in different proportion (formula) of Activated Heavy Shell powder to the solution; thus PET is conducted. At part (II), which the fire-retardant (2-Carboxyethyl (Phenylphosphinic) Acid, CEPPA) in various weight percentages was added during the chemosynthesis of Polyethylene Terephthalate (PET). In part (III), which the fire-retardants (2-Carboxyethyl (Phenylphosphinic) Acid, CEPPA) in fixed weight percentage (3%) and Activated Heavy Shell were added during the chemosynthesis of Polyethylene Terephthalate (PET) in various weight percentages . The chemical structures of these polyesters were investigated by FT-IR. The surface analysis was observed by SEM. The results of EDS showed the existence of C、O、Ca and P elements. For the thermal properties, the thermal degradation behavior of these polyesters was examined by the TGA analysis. The variation in crystallization temperature（Tc）and melting temperature（Tm） were analyzed with DSC. Finally, the fire-retard properties and combustion state of composite materials were investigated by Limit Oxygen Index (L.O.I).
