Description

Aerogel composite material continuous production device and use method TECHNICAL FIELD

[0001] The present application relates to the field of aerogel composite material production, in particular to the field of aerogel composite material continuous production device and use method. BACKGROUND

[0002] Aerogel is a kind of solid porous material with extremely low density and full of gas in space structure, which is obtained by first generating sol through chemical solution reaction, then gel solidification, aging and finally removing the solvent in sol. Therefore, aerogel has high thermal insulation performance, but has the problem of low strength. Therefore, by impregnating the chemical solution or the generated sol into the fiber material, the gel is solidified in the fiber material, and then aging and drying are carried out. Therefore, a solid porous material with extremely low density is generated inside the fiber material, which has relatively high thermal insulation performance and significantly improves the strength of the composite material compared with aerogel.

[0003] Now the application scenarios of aerogel material are many, but the planning production efficiency is low, mainly because the continuous production of aerogel composite material is segmented according to different processes, the production efficiency is low, and the product quality control is difficult.

[0004] Therefore, how to invent a set of continuous production device for aerogel composite material and its use method to realize the continuous production of aerogel composite material has become a difficult problem to be solved in the field.
