| titleOfInvention | Preparation method of double-crosslinking flame-retardant composite aerogel |
| abstract | The invention discloses a preparation method of a double-crosslinking flame-retardant composite aerogel, which comprises the following steps: 1) amino protonation treatment of chitosan: placing chitosan in an acid solution to obtain a chitosan solution with amino groups on a molecular chain protonated; 2) preparing the composite aerogel: dispersing nano montmorillonite into mixed suspension of nano cellulose and chitosan, adding a cross-linking agent, stirring to obtain mixed solution, pouring the mixed solution into a mould, freezing, and performing cross-linking reaction to obtain composite aerogel; 3) a double cross-linking step: and (3) soaking the obtained composite gel in a mixed solution of a polyphosphate solution and a transition metal chloride solution for treatment, and freeze-drying to obtain the double-crosslinking flame-retardant composite aerogel. The composite aerogel material obtained by the invention has excellent flame retardant property, mechanical property and smoke suppression property; the method has the advantages of low raw material source, low production cost and wide application. |
