中文摘要 | 本文主要是以經有機改質後之蒙脫土在鏈延長劑預聚合體 (HEDA、EDA) 進行插層反應,再與聚丁醚二醇 (PTMG)、聚二甲基矽氧烷 (PDMS) 及 H12-4 , 4’二苯甲基二異氰酸鹽 (H17-MDI) 為單體,二甲基丙酸 (DMPA) 為陰離子中心、及三乙基胺 (TEA) 為中和劑之聚氨基甲酸酯預聚合體,合成聚氨基甲酸酯/奈米黏土水性聚合體,實驗中以控制黏土種類、含量來改善其機械性質,並觀察其對染色性之影響。經由表觀及定性分析結果,此方法的確可以成功地達到插層的效果。在機械性質方面,經黏土插層後之PU/CLAY奈米複合材科其拉伸強度隨黏土含量提升而增加而伸長率則隨著黏土含量之增加而下降。在熱性質方面,PU/CLAY奈米複合材料之熱性質皆隨著黏土含量的增加而隨之上升。在染著率方面,當黏土含量增加時,其染著率會下降,但其耐水洗堅牢度則可達4~5級。 |
英文摘要 | The article is using the polyurea prepolymer, which was synthesized from the extender (ethylene diamine (EDA) or N(2-hydroxyethyl) ethylene diamine (HEDA)) and 4,4'-diphenyl- methane diisocyanate (MDI), as an intercalative agent to intercalate the organic modified montmorillonite clay. Then, it is further reacted with the polyurethane prepolymer, which is polymerized from the polytetramethylene glycol (PTMG) and MDI, to proceed the intercalative polymerization to form a polyurethane/clay nanocomposite polymer. The experimental parameters contain the types of organo-clay and also the contents of organo-clay in the polymer etc. We expect better mechanical, thermal properties and also improving the dyeing properties. From the qualitative analysis of the fine structure (X-ray and FT-IR) and mechanical analysis, it is found that the intercalation was successfully achieved. The distance of interlayer spacing was manifestly changed. The mechanical properties are significantly improved as the content of organo-clay is increased. For the dyeing properties, the dyeuptake is lowered down as the amount of organoclay increases, but the dye-fastness is increased to grade of 4-5. |
