SiO2 aerogel/magnesium oxysulfate cement-based thermal insulation mortar and preparation method thereof
The invention provides SiO2 aerogel/magnesium oxysulfate cement-based thermal insulation mortar and a preparation method thereof.The thermal insulation mortar material comprises a component A, a component B, a component C and a component D. The component A comprises 65 parts of light calcined magnesia and 5-50 parts of silicon dioxide aerogel, and the component B comprises 25-35 parts of magnesium sulfate heptahydrate, 0.1-1 part of a modifier, 0-3 parts of a reinforcing agent, 26-32 parts of water, 0-3 parts of a thickener and 0-3 parts of a water repellent. The component C comprises 60-650 parts of water and 1-15 parts of a dispersant, and the component D comprises 0-20 parts of an inert filler, 0-30 parts of prefabricated foam and 0-5 parts of fibers. According to the SiO2 aerogel/magnesium oxysulfate cement-based thermal insulation mortar provided by the invention, the large-volume doped aerogel can be uniformly dispersed in a cement-based material, the problems of interface layering and the like are avoided, and the SiO2 aerogel/magnesium oxysulfate cement-based thermal insulation mortar has the advantages of high strength, light weight, good thermal insulation performance, high softening coefficient and the like.
本发明提供了一种SiO2气凝胶/硫氧镁水泥基保温砂浆及制备方法，其中保温砂浆材料包括组分A、组分B、组分C和组分D，组分A包括：65份轻烧氧化镁、5‑50份二氧化硅气凝胶，组分B包括：25‑35份七水硫酸镁、0.1‑1份改性剂、0‑3份增强剂、26‑32份水、0‑3份增稠剂、0‑3份憎水剂，组分C包括：60‑650份水、1‑15份分散剂，组分D包括：0‑20份惰性填料、0‑30份预制泡沫、0‑5份纤维。本发明提供的SiO2气凝胶/硫氧镁水泥基保温砂浆中的大体积掺量气凝胶能够均匀分散在水泥基材料中，而不出现界面分层等问题，且具有强度高，轻质，保温隔热性能好，软化系数高等优点。
