The invention discloses composite sound-insulation and heat-insulation aerogel soil and a preparation method thereof. The heat-insulation and heat-preservation aerogel soil comprises the following components in parts by weight: 30-50 parts of silicate; 25-45 parts of ash calcium powder; 10-20 parts of glutinous rice mortar; 10-15 parts of aluminum silicate powder; 10-20 parts of hollow microspheres; 10-20 parts of aerogel particles; 15-20 parts of mica powder; 5-10 parts of hydroxyethyl propyl cellulose; and 3-8 parts of lignocellulose. According to the present invention, the lime component iscontained in the glutinous rice mortar, so that the aerogel soil has the anti-corrosion effect, and the mortar in the glutinous rice mortar can form the microstructure similar to the biomineralizer during the curing process so as to make the aerogel soil have characteristics of high strength and strong toughness; and due to the synergistic effect of inorganic/organic matters between nanoscale calcium carbonate generated in the glutinous rice mortar and the wrapped glutinous rice mortar film, the aerogel soil has toughness and also has a good anti-leakage effect, and due to the fact that the glutinous rice mortar has high adhesiveness, the aerogel soil can be better adhered to the wall surface and in gaps of the wall surface.
本发明公开了一种复合隔音绝热气凝胶土及其制备方法，所述隔热保温气凝胶土的组分按重量份数包括：硅酸盐30‑50份；灰钙粉25‑45份；糯米灰浆10‑20份；硅酸铝粉10‑15份；空心微珠10‑20份；气凝胶颗粒10‑20份；云母粉15‑20份；羟乙基丙基纤维素5‑10份；木质纤维素3‑8份。本发明通过糯米灰浆内部含有的石灰成分，使气凝胶土具有防腐的效果，另外糯米灰浆中的灰浆在固化过程会形成类似生物矿化物的微结构，使气凝胶土具有强度高、韧性强的特性，且通过糯米灰浆中生成的纳米级碳酸钙和包裹的糯米浆膜之间的无机/有机物的协同作用，使气凝胶土具有韧性的同时还具有良好的防渗漏的效果，由于糯米灰浆本身具有较强的粘合性，使气凝胶土能够更好的粘黏在墙面上以及墙面的缝隙内。
