Preparation method of yttrium tantalate fiber high-temperature thermal insulation material
The invention belongs to the field of light thermal insulation materials, and particularly relates to a preparation method of an yttrium tantalate fiber high-temperature thermal insulation material. The preparation method of the yttrium tantalate fiber high-temperature thermal insulation material comprises the following steps: dipping viscose fiber felt in an aqueous solution containing tantalum oxalate, yttrium nitrate and polyethylene glycol for a period of time, washing, drying, and carrying out heat treatment to obtain the yttrium tantalate fiber high-temperature thermal insulation material. The yttrium tantalate fiber high-temperature thermal insulation material has the beneficial effects of high temperature resistance, high strength, low thermal conductivity and low density.
本发明属于轻质隔热材料领域，具体涉及一种钽酸钇纤维高温隔热材料的制备方法。公开的一种钽酸钇纤维高温隔热材料的制备方法是将粘胶纤维毛毡在含草酸钽、硝酸钇与聚乙二醇的水溶液中浸渍一段时间，经洗涤、烘干后热处理，从而获得一种钽酸钇纤维高温隔热材料。本发明钽酸钇纤维高温隔热材料的有益效果是：耐高温、高强度、低热导率、低密度。
