Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerogel preparation, in particular to a mixing mechanism for aerogel preparation. Background Art
[0002] Aerogel is a new type of lightweight solid material with a micro-nano porous network structure composed of colloidal particles or polymer molecules aggregated with each other, and the pores are filled with air dispersion medium. The preparation process of aerogel is divided into two steps: preparing wet gel and drying the wet gel by special techniques. The most traditional preparation method of wet gel is the sol-gel method, in which compounds containing highly chemically active components are dispersed in a solvent, and active monomers are generated through hydrolysis reaction. The active monomers are polymerized to form a sol, and then a gel with a certain spatial structure is generated. The gel produced at this time is a bit like jelly. Then the jelly-like gel is further dried to obtain aerogel. In the process of solvent mixing reaction, a stirring device is often used to assist mixing, so that the solvents can be quickly contacted and mixed to accelerate the solvent reaction rate. However, the stirring device is easy to re-destroy the parts of the solvent that have already reacted, so that the overall structure is formed slowly, resulting in the problem of reduced wet gel forming rate.
