The invention relates to the technical field of heat preservation and heat insulation of buildings, in particular to lightweight aerogel which comprises a raw material A and a raw material B, the mass ratio of the raw material A to the raw material B is 3: 1; the raw material A comprises the following parts in parts by weight: 153-163 parts of purified water, 45-55 parts of magnesium oxide and 45-55 parts of mica; the mass ratio of magnesium oxide to mica is 1: 1; the raw material B comprises the following parts in parts by weight: 155-161 parts of purified water and 1.6-7.6 parts of an expanding agent; the expanding agent comprises the following parts in parts by weight: 15-20 parts of polyvinyl alcohol; 5-10 parts of glyoxal, 70-78 parts of water, 0.1-1.8 parts of acetic acid and 0.05-0.25 part of antioxidant. The aerogel provided by the invention has the advantages of small volume weight and favorable heat-conducting property, and can meet the requirements of building construction on filled thermal insulation materials.
本发明涉及建筑保温隔热技术领域，尤其涉及一种轻质气凝土，包括原料A和原料B；原料A和原料B的质量比为3:1；按重量份计，原料A包括以下组分：纯净水153～163份、氧化镁45～55份和云母45～55份；氧化镁和云母的质量比为1:1；按重量份计，原料B包括以下组分：纯净水155～161份和膨胀剂1.6～7.6份；按重量份计，膨胀剂包括以下组分：聚乙烯醇15～20份；乙二醛5～10份、水70～78份、乙酸0.1～1.8份和抗氧剂0.05～0.25份。本发明提供的气凝土容重小，良好的导热性能，能满足建筑施工对填充式保温隔热材料的需求。
