Preparation method of aerogel mortar
The invention discloses a preparation method of aerogel mortar, and belongs to the field of building materials. Stirring the decoration waste recycled fine aggregate, a cementing material, an additive and a water reducing agent aqueous solution to obtain mortar; the preparation method comprises the following steps: stirring and modifying hydrophobic SiO2 aerogel particles in a gamma-aminopropyltriethoxysilane aqueous solution, so as to obtain hydrophilic SiO2 aerogel particles; the preparation method comprises the following steps: dispersing a hydrophilic SiO2 aerogel particle dispersion solution, adding mortar, and stirring until the SiO2 aerogel particles are completely fused into the mortar to obtain the aerogel mortar, which is excellent in thermal insulation performance and environment-friendly.
本发明公开了一种气凝胶砂浆的制备方法，属于建筑材料领域。将装修垃圾再生细骨料、胶凝材料、外加剂与减水剂水溶液搅拌，得到砂浆；将疏水型SiO2气凝胶颗粒在γ‑氨丙基三乙氧基硅烷水溶液中搅拌改性，得到具有亲水性的SiO2气凝胶颗粒；将具有亲水性的SiO2气凝胶颗粒分散溶液分散后加入砂浆搅拌，至SiO2气凝胶颗粒完全融入砂浆中，制得气凝胶砂浆，本发明的气凝胶砂浆保温性能优良且对环境友好。
