| titleOfInvention | Heat-resistant phenolic aerogel and preparation method thereof |
| abstract | The invention relates to a preparation method of heat-resistant phenolic aerogel, which comprises the following steps: s1, synthesizing boron modified phenolic resin; s2, mixing the boron modified phenolic resin with a curing accelerator and a solvent to obtain a phenolic resin solution; s3, gelatinizing the phenolic resin solution under a sealed condition to obtain phenolic wet gel; and S4, drying the phenolic aldehyde wet gel at normal pressure to obtain the heat-resistant phenolic aldehyde aerogel. The heat-resistant phenolic aerogel is prepared by adopting a sol-gel-normal pressure drying process, the phenolic aerogel obtained by boron modification has the advantages of high heat resistance, high network skeleton strength and the like, and the raw materials adopted by the preparation method are all universal chemical raw materials and are low in price; and a curing agent hexamethylene tetramine is not required to be added in the preparation process, so that no ammonia gas is emitted in the curing process, and the operation environment is friendly. |
