Carbon-absorbing and sound-insulating lightweight board and preparation method thereof
The invention provides a carbon-absorbing and sound-insulating lightweight board. The carbon-absorbing and sound-insulating lightweight board comprises the following components in parts by weight: 60-100 parts of a carbonized cementing material; 30 to 50 parts by weight of aminated aerogel; and 5-10 parts by weight of a carbonization reinforcing agent. Compared with the prior art, the lightweight board has the advantages that the carbonized cementing material is used as a main body, the aminated aerogel is added, and the aminated aerogel not only has larger specific surface area and higher porosity, but also contains basic groups, and can selectively and effectively adsorb carbon dioxide through combination of chemical adsorption and physical adsorption, so that the lightweight board not only can insulate sound, but also can effectively adsorb carbon dioxide; the influence of noise is reduced, a large amount of carbon dioxide can be absorbed and fixed, and emission of carbon dioxide is reduced; meanwhile, the carbonization reinforcing agent is added, so that the breaking strength of the light board is improved.
本发明提供了一种吸碳、隔音轻质板材，包括：碳化胶凝材料60～100重量份；氨基化气凝胶30～50重量份；碳化增强剂5～10重量份。与现有技术相比，本发明以碳化胶凝材料为主体，添加氨基化气凝胶，氨基化气凝胶不仅具有较大的比表面积、较高的孔隙率，还含有碱性基团，可通过化学吸附与物理吸附的结合选择性地有效吸附二氧化碳，使轻质板材不仅可以隔音，降低噪音的影响，还能够大量吸收和固定二氧化碳，减少二氧化碳的排放；同时添加碳化增强剂，提高了轻质板材的抗折强度。
