| titleOfInvention | A kind of flame retardant nanocellulose composite aerogel with directional structure and preparation method thereof |
| abstract | The invention provides a flame-retardant nanocellulose composite aerogel with a directional structure and a preparation method thereof. , to obtain a composite nanocellulose hydrogel; S2, performing solution replacement of the composite nanocellulose hydrogel in an alcohol solution containing a carbonizing agent to obtain an alcohol gel containing a carbonizing agent; the carbonizing agent is preferably a Methylbenzenesulfonic acid; S3, directional freezing the alcohol gel containing the carbonizing agent to obtain a flame-retardant nanocellulose composite aerogel with a directional structure. In the preparation process of the present invention, the addition of carbonizing agents such as toluene sulfonic acid improves the degree of carbonization of its own cellulose and blocks the transfer of heat and combustible volatile components; at the same time, siloxane is introduced in situ during preparation, which further acts as a hindrance. combustion effect. The nanocellulose composite aerogel of the present invention has low thermal conductivity and excellent thermal insulation performance. |
