Modified silica fume porous lightweight concrete-based thermal insulation material and preparation method thereof
The invention discloses a modified silica fume porous lightweight concrete-based thermal insulation material and a preparation method thereof, and belongs to the technical field of thermal insulation materials. Every 100 parts by mass of slurry of the material is prepared from the following components: 25.0 to 27.2 parts of cement, 36.0 to 37.1 parts of superfine filler, 0.9 to 3.1 parts of modified silica fume, 0.6 to 1.6 parts of lime, 0.7 to 1.2 parts of early strength agent, 0.2 to 0.4 part of foam stabilizer, 0.2 to 0.4 part of foaming agent, 0.4 to 0.9 part of water reducing agent and 31.3 to 32.6 parts of water. The silica fume with the specific particle size is modified, the contact angle of the silica fume is controlled to be in an optimal range, and at the moment, the modified silica fume can be stably adsorbed to a gas-liquid interface, so that the foam stabilizing effect of slurry is greatly improved, and the pore structure and the thermal insulation performance of the porous lightweight concrete-based thermal insulation material are further optimized. The modified silica fume porous lightweight concrete-based thermal insulation material provided by the invention has the advantages of light weight, excellent thermal insulation and sound insulation effects, good strength performance and low cost, and is suitable for various thermal insulation scenes.
本发明公开了一种改性硅灰多孔轻质混凝土基保温材料及其制备方法，属于保温材料技术领域。该材料每100质量份料浆组成成分为：水泥25.0～27.2份、超细填料36.0～37.1份、改性硅灰0.9～3.1份、石灰0.6～1.6份、早强剂0.7～1.2份、稳泡剂0.2～0.4份、发气剂0.2～0.4份、减水剂0.4～0.9份以及水31.3～32.6份。本发明通过对特定粒径的硅灰进行改性处理，控制其接触角在一最佳范围，此时的改性硅灰能稳定吸附至气液界面从而大大提升料浆的稳泡效果，进而优化了多孔轻质混凝土基保温材料的孔隙结构和保温性能。本发明提出的改性硅灰多孔轻质混凝土基保温材料具有轻质、保温和隔声效果优异、强度表现良好且成本低廉的优点，适用于多种保温场景。
