Method for preparing carbon-coated silicon dioxide micro-nano fiber aerogel material from waste material
The invention discloses a method for preparing a carbon-coated silicon dioxide micro-nano fiber aerogel material from waste materials, which comprises the following steps: (1) preparing a spinnable raw material mixed solution: dissolving a polymer in a solvent to form a polymer solution; adding the catalyst, the polymer solution and the silicon source into a stirrer according to the charging sequence of the catalyst, the polymer solution and the silicon source or the charging sequence of the silicon source, the polymer solution and the catalyst, stirring for a second stirring time at a second stirring speed, and standing to obtain a spinnable raw material mixed solution; (2) preparing a precursor; (3) sintering the precursor: putting the precursor and the waste material into a closed sintering furnace for high-temperature sintering to finally obtain a sintered product which is a black micro-nano fiber substance, namely the carbon-coated silicon dioxide micro-nano fiber material; the mass ratio of the precursor to the waste material is less than or equal to 1: 5. The manufacturing cost of the carbon-coated silicon dioxide micro-nano fiber is reduced, the waste utilization rate can be increased, and carbon emission is reduced.
本申请公开了一种利用废弃物料制备碳包覆二氧化硅微纳米纤维气凝胶材料的方法，包括以下步骤：(1)制备可纺性的原材料混合溶液：将聚合物溶于溶剂中，形成聚合物溶液；再按照催化剂、聚合物溶液和硅源的加料顺序或硅源、聚合物溶液和催化剂的加料顺序加入搅拌器中，以第二搅拌速度搅拌第二搅拌时间后静置，得到可纺性的原材料混合溶液；(2)制备前驱体；(3)烧结前驱体：将前驱体和废弃物料放入密闭烧结炉中进行高温烧结，最终得到的烧结产物为黑色微纳米纤维物质，即碳包覆二氧化硅微纳米纤维材料；所述前驱体与废弃物料的质量比≤1:5。本发明在降低碳包覆二氧化硅微纳米纤维制造成本的同时还能提升废物利用率，减少碳排放。
