Preparation method of high-temperature thermal insulation material containing zirconium carbide
The invention belongs to the technical field of light thermal insulation materials, and particularly relates to a preparation method of a high-temperature thermal insulation material containing zirconium carbide. The preparation method of the zirconium carbide-containing high-temperature thermal insulation material comprises the following steps: soaking a zirconium oxide fiberboard into absolute ethyl alcohol uniformly dispersed with nano carbon and resin for a period of time, then drying the zirconium oxide fiberboard into a drying box, and then carrying out nitriding heat treatment to form the zirconium carbide-containing high-temperature thermal insulation material. After the carbon source is introduced into the prepared zirconium oxide fiberboard and heat treatment is carried out, carbon reacts with zirconium oxide to generate zirconium carbide, so that the rigidity and the mechanical strength of the fiberboard can be improved, and meanwhile, the problem of pulverization and powdering can be solved.
本发明属于轻质隔热材料技术领域，具体涉及一种含碳化锆的高温隔热材料的制备方法。涉及的一种含碳化锆的高温隔热材料的制备方法是将氧化锆纤维板浸渍于分散均匀有纳米碳和树脂的无水乙醇中一段时间，接着将其置于干燥箱中烘干，之后进行氮化热处理，形成一种含碳化锆的高温隔热材料。本发明中所制备的氧化锆纤维板经引入碳源并热处理后，碳与氧化锆反应生成碳化锆，可增加纤维板的刚性和机械强度，同时减少了粉化和掉渣现象。
