Preparation method of zirconium oxide fiber cotton
The invention discloses a preparation method of zirconium oxide fibers. Belongs to the field of new materials. The preparation method comprises the following steps: taking basic zirconium carbonate, glacial acetic acid, yttrium nitrate hexahydrate and other additives as main raw materials, dissolving the main raw materials in distilled water according to a certain ratio, and fully stirring at 40-80 DEG C until the solution is colorless and in a uniform state; carrying out vacuum concentration on the solution at 70-80 DEG C to obtain a proper solution with certain viscosity, adding solvents such as DMSO, NMP, DMF, DMAc and the like, and mixing to prepare a precursor solution capable of carrying out electrostatic spinning; the precursor spinning solution is subjected to electrostatic spinning to obtain fibril, and the fibril is subjected to high-temperature heat treatment to obtain the zirconium oxide fiber cotton. The diameter of the zirconium oxide fiber is 100-2000 nm, the zirconium oxide fiber is continuous and good in flexibility, the volume density of the fiber cotton ranges from 8 mg/cm < 3 > to 300 mg/cm < 3 >, and the fiber cotton can be used in the field of heat insulation and heat preservation.
本发明公开了一种氧化锆纤维的制备方法。属于新材料领域。本发明以碱式碳酸锆、冰乙酸、六水合硝酸钇等添加剂为主要原料，按照一定配比溶于蒸馏水，在40～80℃条件下充分搅拌至溶液无色、均一状态；在70～80℃将溶液减压浓缩至具有一定粘度、适合的溶液，再添加DMSO、NMP、DMF、DMAc等溶剂混合配置成可静电纺丝的的前驱体溶液；所得前驱体纺丝液通过静电纺丝获得原纤维，再经高温热处理制得氧化锆纤维棉。所述氧化锆纤维直径为100～2000nm，连续、柔韧性好，纤维棉的体积密度范围在8mg/cm3‑300mg/cm3范围，可以用于绝热保温领域。
