摘要

本研究以聚氨酯(PU)/聚乳酸(PLA)製成發泡材料，並探討不同比例防燃劑及改質蒙脫土(TCPP/CPC-Clay)發泡體材料之發泡密度、孔徑大小影響、硬度、衝擊強力、拉伸應變、彈性回復率及壓縮強力等機械性能進行測試分析、由實驗發現，發泡材密度隨著CPC-Clay混合比 增加之下，使發泡材密度下降並影響衝擊強力硬度彈性回復率壓縮強力拉伸應變等性質降低，本研究中亦發現聚氨酯/聚乳酸混合比例80/20及TCPP/CPC-Clay混合比在濃度30%時TCPP/CPC-Clay比例(1.0/0)具有較佳之密度及機械性質，另外LOI與垂直燃燒則是混合比在濃度30%及TCPP/CPC-Clay比例分別為(1.0/0)(0.8/0.2)時具有較佳的防燃效果。

In this study, the flame resistant foam materials made from polyurethane (PU) / polylactic acid (PLA) composite with different ratio of Tris(1-chloro-2-propyl) phosphate (TCPP)/ montmorillonite clay (Clay), the mechanical and forming properties of PU/PLA foam materials were investigated by pore size, hardness, impact strength, tensile stretch strain, elastic recovery and compression strength. From experimental results that the pore size of the foam material increased with CLAY increasing, but the density, impact strength, hardness, elastic recovery, compression properties, tensile strain of PU/PLA foam were decreased. Moreover, the flame resistant PU/PLA at mixing ratio 80/20 and TCPP / CPC-Clay at 1.0/ 0, 0.8/0.2 had were got better density and mechanical properties.
