摘要

本研究目的以黃麻編織纖維布(woven jute fiber cloth，Jf)補強聚丙烯(Polypropylene，PP)，並添加入市售阻燃劑以增添PP之應用範圍。以及添加馬來酸酐接枝聚丙烯(Maleic anhydride grafted polypropylene, MAPP)做為相容劑，並將Jf進行化學處理以及矽烷偶合劑(3-Aminopropyltriethoxysilane)進行改質，以提升複合材料之性質。實驗結果顯示，經FT-IR分析顯示Jf係由編織黃麻線、PE纖維以及PP/PE共混纖維所組成，在阻燃劑發現C-Br的吸收峰以及Sb2O3的吸收峰。經TGA分析，複合材料相容性提升後在Td5以及Td20溫度也皆有提升，焦碳含量也有增加的趨勢。拉伸強度與耐衝擊強度測試結果顯示，以含經由鹼處理Jf之PP/MA/BJf有最佳的拉伸以及耐衝擊強度。UL-94測試結果顯示，添加入阻燃劑之複合材料，阻燃性達到最高等級V-0。SEM分析可以觀察到經由化學處理可以提高Jf與PP間相容性。綜合以上結果顯示，黃麻編織纖維布補強聚丙烯複合材料，能以低成本補強聚丙烯，並增添聚丙烯之應用範圍。

In this study, woven jute fiber cloth (Jf) was used to reinforce polypropylene (PP), and a commercially available flame retardant was added to increase the application PP. Maleic anhydride grafted polypropylene (MAPP) was added as a compatibilizer. Moreover, Jf was chemically treated and modified by 3-Aminopropyltriethoxysilane to enhance the properties of the composites. The results showed that the absorption peaks of C-Br and Sb2O3 were found in the FTIR spectrum of flame retardant. And the Jf is composed of jute yarn, PE fiber and PP/PE blending fiber. TGA analysis revealed that the decomposition temperatures (Td5 and Td20) of the composites were increased by improving the compatibility of the composites, and char yield was also increased. The results of tensile and impact tests showed that PP/MA/BJf exhibited the best tensile and impact strengths. The results of UL-94 test showed that the flame retardancy of the flame retardant containing composite materials can achieve the highest level (V-0). SEM analysis can be observed that the compatibility between Jf and PP was improved by the chemical treatment of Jf. Based on the above results, Jf reinforced PP composite materials can reinforce PP with low cost, and increase the applications of PP.
