Ambient-pressure drying preparation method for mineral nanofiber aerogel
The invention relates to an ambient-pressure drying preparation method for mineral nanofiber aerogel. Nonmetallic mineral raw materials are purified and scattered, so that mineral nanofibers are acquired; the mineral nanofibers are scattered in a proper amount of water, a foaming agent, a bonder and the like are added, a mixture is fully and evenly stirred, and even colloidal sol containing a certain number of the nanofibers is acquired; the colloidal sol is converted into stable foam through physical foaming or chemical foaming or physical-chemical foaming; the foam is poured into a mold, ambient-pressure drying or ambient-pressure maintenance-drying is conducted, and therefore the mineral nanofiber aerogel is acquired. The prepared mineral nanofiber aerogel is simple in process, short in production period, high in controllability, low in equipment requirement and easy to industrially produce on a large scale. The prepared mineral nanofiber aerogel has the advantages of being controllable in shape, low in density and heat conductivity, good in mechanical property and the like.
