Porous thermal insulation material as well as preparation method and application thereof
The invention provides a preparation method of a porous thermal insulation material, which comprises the following steps: S1) mixing silicon-aluminum binary sol and a coagulant to obtain sol; s2) impregnating a fibrofelt in the sol, and performing amino modification after gelling to obtain a modified fibrofelt; and S3) drying the modified fibrofelt to obtain the porous thermal insulation material. The invention further provides the porous thermal insulation material and application thereof. The porous thermal insulation material provided by the invention has the characteristics of high porosity, high temperature resistance, good thermal insulation performance, elasticity and light weight, can realize physical adsorption of gas generated in a battery thermal runaway process, and has the advantages of good low-concentration adsorption effect, strong adsorption binding energy, no desorption secondary pollution risk and the like.
本发明提供了一种多孔隔热材料的制备方法，包括以下步骤：S1）将硅铝二元溶胶和促凝剂混合，得到溶胶；S2）将纤维毡浸渍在所述溶胶中，凝胶后进行氨基修饰，得到修饰的纤维毡；S3）将所述修饰的纤维毡进行干燥，得到多孔隔热材料。本申请还提供了一种多孔隔热材料及其应用。本申请提供的多孔隔热材料具有孔隙率高、耐高温、隔热性能好和弹性轻质的特点，可实现对电池热失控过程产生气体的物理吸附，且具有低浓度吸附效果好、吸附结合能强、无脱附二次污染风险等优点。
