Preparation method of zirconium oxide fiber heat insulation product
The invention belongs to the technical field of fiber heat insulation materials, and relates to a preparation method of a zirconium oxide fiber heat insulation product. The preparation method of the zirconium oxide fiber heat insulation product comprises the steps: firstly, dissolving precursor metal zirconium salt into a solvent, stirring in a water bath kettle at a constant temperature, and adding a catalyst and an additive in the stirring process to obtain precursor zirconium-containing sol; dipping a viscose acetal fiber template in the prepared zirconium-containing sol, washing with water to remove redundant metal salt solution, drying, and circulating the step to obtain a zirconium-containing precursor fiber; carrying out heat treatment on the precursor fiber in a rapid heating furnace to obtain a flaky zirconium oxide fiber block; and crushing the flaky zirconium oxide fiber block, uniformly dispersing the crushed flaky zirconium oxide fiber block into prepared dispersion liquid containing zirconium sol to obtain stable slurry, and pouring the stable slurry into a mold for treatment to obtain the zirconium oxide fiber heat insulation product with good high-temperature resistance. The zirconium oxide fiber material prepared by the method is uniform in morphology, low in product density and good in heat insulation performance.
本发明属于纤维隔热材料技术领域，涉及一种氧化锆纤维隔热制品的制备方法。涉及的一种氧化锆纤维隔热制品的制备方法：先将前驱金属锆盐溶解到溶剂中，在水浴锅中恒温搅拌，搅拌过程中添加催化剂和添加剂，得到前驱含锆溶胶；将黏胶纤维模板在配制的含锆溶胶中浸渍，然后用水洗除去多余的金属盐溶液，干燥，循环该步骤后得到含锆前驱体纤维；将前驱体纤维在快速升温炉中热处理，即可得到片状氧化锆纤维块体；把片状的氧化锆纤维块体打碎，均匀分散到配制好的含有锆溶胶的分散液中，得到稳定的浆体，将稳定的浆体倒入的模具中处理得到耐高温性能良好的氧化锆纤维隔热制品。本发明所制备的氧化锆纤维材料形貌均匀，制品密度低，隔热性能好。
