Abstract
A preparation method for a silica aerogel, comprising the following steps: A) raw material containing a solid silicon source and an alkaline solution is used to produce an aerogel precursor after mixing; and B) the aerogel precursor is dried to obtain a silica aerogel. An improved silica aerogel preparation method, comprising the following steps: A) a cation exchange resin and a silicate solution are used as raw materials and mixed; B) the mixed material is allowed to stand to obtain an aerogel precursor; and C) the aerogel precursor is dried to obtain a silica aerogel.

A method for preparing silica aerogel, comprising the following steps:
- A) mixing uniformly mixed silicon phosphate, sodium silicate and water with gel core particles to obtain a precursor under a sealed condition;
- the gel core particles comprise one or more of white carbon black and silica powder;
- B) drying the precursor to obtain a silica aerogel.
