Preparation method of silicon oxide ceramic fiber aerogel heat insulation film
The invention discloses a preparation method of a silicon oxide ceramic fiber aerogel heat insulation film, and belongs to the technical field of heat insulation materials, and the preparation method comprises the following steps: 1, preparing a spinning solution by a sol-gel method, dissolving a zirconium source in water, and adding a phase inhibitor at the same time to form a solution A; dissolving a silicon source in water to form a solution B; mixing the solution A and the solution B, adding a polymer template, and uniformly mixing to obtain a spinning solution; 2, preparing a precursor film through electrostatic spinning; 3, calcining the precursor film; and 4, hydrophobic modification of the fiber membrane. The heat insulation film is a zirconium oxide-silicon oxide ceramic fiber film, and in silicon oxide doped zirconium oxide fibers, zirconium oxide mainly exists in a tetragonal crystal form; according to the invention, electrostatic spinning is assisted by airflow, so that the flexibility and continuity of fibers are better; silicon, zirconium and yttrium in the heat-insulating film are uniformly distributed in fibers, so that the heat-insulating film is uniform in texture and good in comprehensive performance.
本发明公开了一种氧化硅陶瓷纤维气凝胶隔热膜的制备方法，属于隔热材料技术领域，包括以下步骤：第一步、溶胶凝胶法制备纺丝液，取锆源溶解在水中，同时加入相抑制剂，形成A液；取硅源溶解于水中，形成B液；将A液和B液混合，加入聚合物模板，混合均匀后即为纺丝液；第二步、静电纺丝制备前驱体膜；第三步、前驱体膜煅烧；第四步、纤维膜疏水改性。本发明的隔热膜为氧化锆‑氧化硅陶瓷纤维膜，经氧化硅掺杂的氧化锆纤维中，氧化锆主要以四方晶型存在；本发明通过气流辅助静电纺丝，纤维的柔性和连续性较好；本发明的隔热膜中硅、锆、钇在纤维中分布均匀，使得隔热膜质地均匀，综合性能好。
