Method for simultaneously preparing silicon dioxide aerogel and carbon-coated silicon dioxide aerogel material
The invention discloses a method for simultaneously preparing silicon dioxide aerogel and a carbon-coated silicon dioxide aerogel material, and belongs to the field of ceramic aerogel materials.The preparation method comprises the steps that 1, a spinnable raw material mixed solution is prepared, 2, a precursor is prepared, 3, the precursor is sintered, respectively putting into two hearths for sintering, and introducing dense smoke containing carbides generated by sintering in the first hearth into the second hearth; the mass ratio of the first precursor to the second precursor is greater than or equal to 3. The preparation process is simple, the production cost is low, the carbon emission is low, and the obtained aerogel product is a flexible ceramic material with the characteristics of good thermal stability, chemical stability, high porosity, low density, high liquid absorption rate and the like.
本申请公开了一种同时制备二氧化硅气凝胶和碳包覆二氧化硅气凝胶材料的方法，属于陶瓷气凝胶材料领域，制备方法包括：(1)制备可纺性的原材料混合溶液：(2)制备前驱体：(3)烧结前驱体：将制得的前驱体分割为两份，分别放入两个炉膛中进行烧结，将第一炉膛中烧结产生的含有碳化物的浓烟通入第二炉膛中；第一份前驱体与第二份前驱体的质量比≥3。本发明制备流程简单、生产成本低、碳排放低，所得气凝胶产品是具有良好的热稳定性、化学稳定性、高孔隙率、低密度、高吸液率等特点的柔性陶瓷材料。
