| titleOfInvention | CS-SiO modified by cellulose2Method for producing aerogels |
| abstract | CS-SiO modified by cellulose 2 A method for preparing aerogel, relating to a modified CS-SiO 2 A method for producing an aerogel. The invention aims to solve the problem of the existing CS-SiO 2 The framework of the composite aerogel is fragile, and the composite aerogel is difficult to form under the vacuum freeze drying technology. The invention comprises the following steps: firstly, extracting nano-cellulose; secondly, cellulose modified CS-SiO 2 Preparing mixed gel; and thirdly, freezing and drying. The invention extracts nano-cellulose from wood powder and adds the nano-cellulose into CS-SiO 2 The modification is carried out in the aerogel, so that the mechanical property of the silica aerogel is greatly enhanced, and the advantages of high porosity, good heat-insulating property and the like are reserved. The invention relates to cellulose modified CS-SiO prepared by a sol-gel method and a vacuum freeze-drying method 2 The composite aerogel can obviously improve CS-SiO on the premise of controlling low density, low heat conductivity coefficient and high specific surface area 2 Mechanical strength of the aerogel. |
