Method for preparing hollow aluminum titanate fibers from kapok fibers
The invention discloses a method for preparing hollow aluminum titanate fibers from kapok fibers, which comprises the following steps: by using kapok fibers as a template and ethanol as a solvent, soaking the kapok fibers in a mixed solution of aluminum nitrate, butyl titanate and magnesium chloride, introducing butyl titanate and aluminum nitrate into the wall of a kapok fiber tube, and carryingout high-temperature sintering by using magnesium chloride as a stabilizer to obtain the hollow aluminum titanate fibers. carrying out a chemical reaction on the kapok fibers to generate aluminum titanate which exists in the wall of the kapok fiber pipe, decomposing the kapok fibers and ablating at high temperature, leaving the aluminum titanate, and obtaining hollow aluminum titanate fibers. Theprepared aluminum titanate fiber is of a hollow tubular structure, fluffy and high in hollowness, a certain gap can be kept between the fibers, and structural advantages can be provided for obtainingexcellent heat insulation performance.
本发明公开了一种利用木棉纤维制备中空钛酸铝纤维的方法，以木棉纤维为模板，采用乙醇为溶剂，木棉纤维经硝酸铝、钛酸丁酯、氯化镁的混合溶液浸泡后，钛酸丁酯、硝酸铝进入到木棉纤维管壁中，氯化镁作为稳定剂，经过高温烧结，发生化学反应生成钛酸铝，存在于木棉纤维管壁中，较高温度时木棉纤维分解烧蚀，留下钛酸铝，获得中空的钛酸铝纤维。本发明制得的钛酸铝纤维呈空心管状结构，蓬松，中空度高，且纤维与纤维之间能保持一定空隙，可为获得优异的隔热性能提供结构上的优势。
