【摘要】: 鎂鋁水滑石是一種新型的無機阻燃材料,應用前景十分廣泛。鎂鋁水滑石晶須能夠在不惡化材料機械性能的情況下,達到阻燃的目的,因此是一種高性價比且極有應用前途的阻燃劑。 本文研究了超聲一步法制備鎂鋁水滑石試樣。采用掃描電鏡、X-射線衍射儀和X-射線能譜儀分析所得試樣,發(fā)現(xiàn)采用超聲一步法可以制備出鎂鋁水滑石晶須。研究了不同鎂源、不同鋁源、不同超聲時間、不同陳化溫度和不同陳化時間對鎂鋁水滑石晶須制備的影響。通過能譜分析儀對試樣進行分析,發(fā)現(xiàn)鎂鋁水滑石中[Mg~(2+)]與[Al~(3+)]的摩爾比并不嚴格為3:1,形貌越接近晶須狀,[Mg~(2+)]與[Al~(3+)]的摩爾比越大。并且,本文對材料計算進行了探索,計算了鎂基氫氧化物和鎂基氧化物的晶格振動及熱學性質(zhì),為優(yōu)化實驗方案提供了理論依據(jù)。
[Abstract]:Magnesium aluminum hydrotalcite is a new kind of inorganic flame retardant, which has a wide application prospect. The magnesium aluminum hydrotalcite whisker can achieve the purpose of flame retardancy without deteriorating the mechanical properties of the material, so it is a kind of highly cost-effective and promising flame retardant.
This paper has studied the preparation of magnesium aluminum hydrotalcite by one step ultrasonic method. Using scanning electron microscope, X- ray diffractometer and X- ray energy spectrometer, we found that the magnesium aluminum hydrotalcite whisker can be prepared by ultrasonic one step method. Different magnesium sources, different aluminum sources, different ultrasonic time, different aging temperature and aging time have been studied for magnesium aluminum. The effect of the preparation of hydrotalcite whisker. The mole ratio of [Mg~ (2+) and [Al~ (3+)) in magnesia aluminum hydrotalcite was not strictly 3:1, the morphology was closer to the whisker, the larger the molar ratio of [Mg~ (2+) and [Al~ (3+)). Furthermore, the material calculation was explored and the magnesium based hydroxide and magnesia based oxygen were calculated in this paper. The lattice vibration and thermal properties of the compounds provide a theoretical basis for optimizing the experimental scheme.
