Building waste sintered brick for heat preservation and preparation method thereof
The invention discloses a construction waste sintered brick for thermal insulation and a preparation method thereof, and relates to the technical field of sintered bricks. The modified fly ash is wrapped with aerogel, fine coal gangue and construction waste can be embedded into surface mesopores of the modified fly ash, then the modified fly ash, starch, the modified fly ash and sludge are sintered for brick making, in the sintering process, the aerogel is carbonized to form a fixed structure, sintering shrinkage deformation of the fly ash is inhibited, the starch forms carbon microspheres and is connected with the carbon aerogel, and the carbon aerogel and the modified fly ash are combined. And then wetting the green brick with a sodium hydroxide solution, and performing secondary sintering, so that a solid network-shaped supporting structure is formed in the brick body, the mechanical property and the thermal insulation property of the sintered brick are improved, internal pores of the sintered brick are regulated and controlled, and the sintered brick is prevented from being too high in water absorption rate.
本发明公开了一种保温用建筑垃圾烧结砖及其制备方法，涉及烧结砖技术领域。本发明利用气凝胶包裹改性粉煤灰，能够使细小的煤矸石、建筑垃圾嵌入改性粉煤灰表面介孔中，然后与淀粉、改性粉煤灰、污泥烧结制砖，在烧结过程中，气凝胶碳化，形成固定结构，抑制粉煤灰烧结收缩变形，淀粉形成炭微球，连结炭气凝胶，然后用氢氧化钠溶液润湿砖坯，进行第二次烧结，使得砖体内部形成固态网络状支撑结构，提高烧结砖的力学性能和保温性能，并且调控烧结砖内部孔隙，防止烧结砖过高的吸水率。
