摘要

本研究主要探討添加非鹵磷酸酯阻燃劑對PC/ABS物理性質及阻燃性質的影響。PC/ABS摻合物以聚碳酸酯樹脂（PC）/丙烯??-丁二烯-苯乙烯聚合物（ABS）80% / 20% 比例摻合，再添加非鹵磷系阻燃劑三苯基磷酸酯（TPP）與其他添加劑混合後，押出造粒經射出成型得各項測試所需之試驗試片，進行機械性質、熱性質及耐燃性質等測試。測試結果再與FR PC/ABS市售產品進行品質比較。
實驗結果顯示，PC/ABS添加13phr以上的TPP，可達到UL94 V-0阻燃等級。增加TPP的量可提高PC/ABS塑料融熔指數（MI），但耐衝擊強度（IZOD）、軟化點溫度（SP）、熱變形溫度（HDT）、拉伸強度（TS）及彎曲強度（FS）均降低。
經由本研究以交叉分析之方法可求出最佳化之產品的配方比例，以期產品各項性質達到所需之最佳化強度與熱特性。相較於其他市售產品，難燃PC/ABS摻合物之熱性質（軟化點溫度及熱變形溫度）稍較低外，融熔指數、拉伸強度、彎曲強度則與其他市售產品匹配，但耐衝擊強度卻高於其他市售品。

A systematic study of the influence of the non-halogen phosphorus flame retardant, triphenyl phosphate (TPP), on the physical properties of the Polycarbonate (PC)/ Acrylonitrile-Butadiene-Styrene polymer (ABS) 80%/20% PC/ABS blend was conducted to be proved a better quality.
PC/ABS blend mixing with TPP and other additives were to extrude as grains which were injected as test specimens for further testing on mechanical property, thermal property and flame-resistance nature. Test results then were used to compare with other commercial similar materials.
PC/ABS added more than 13phr of TPP comply with UL94 V-0 grades in this research. As the amount of TPP was increased, melting index (MI) increased, but the impact strength (IZOD), the vicat softening point temperature (SP), the heat distortion temperature (HDT), the tensile strength (TS) and flexural strength (FS) decreased.
Compared to other commercial products on the market, flame-retarded PC/ABS blends have worse heat properties (vicat softening point temperature and heat distortion temperature), but their melting index, tensile strength, and flexural strength are as good as other products on the market. However, their impact strength is higher than other products on the market.
