Embodiment 1
[0061] Place 45m long, 1.2m wide, and 10mm thick glass fiber mats in the form of rolls in a suitable container, take water glass and deionized water and mix them uniformly at a volume ratio of 1:2 to obtain a silicon-containing solution, and mix the silicon-containing solution with Add ethanol and 1 mol / L sulfuric acid solution into a stirring tank at a volume ratio of 3:1:2 and mix evenly. After stirring for 30 min, pour the sol into a container where glass fiber felt is placed, and keep it warm at 40°C for 6 hours until it gels. After gelling, put the glass fiber mat and gel complex as a whole into the acid alcoholization solution, the amount of the acid alcoholization solution is at least less than the glass fiber mat and the gel complex as a whole, keep warm at 60°C, and the acid alcoholization solution is mixed with 40% sulfuric acid solution Prepare with absolute ethanol at a volume ratio of 1:8. After 6 hours, put the glass fiber mat and gel composite into a mixed soluti...

[0063] Place 45m long, 1.5m wide, and 10mm thick glass fiber mats in the form of rolls in a suitable container, take water glass and deionized water and mix them uniformly at a volume ratio of 1:1 to obtain a silicon-containing solution, and mix the silicon-containing solution with Add ethanol and 1 mol / L sulfuric acid solution into a stirring tank at a volume ratio of 1:1:1 and mix evenly. After stirring for 30 min, pour the sol into a container with glass fiber mats and keep it warm at 60°C for 6 h until it gels. After gelling, put the glass fiber mat and gel complex as a whole into the acid alcoholization solution, the amount of the acid alcoholization solution is at least less than the glass fiber mat and the gel complex as a whole, keep warm at 60°C, and the acid alcoholization solution is mixed with 40% sulfuric acid solution Prepare with absolute ethanol at a volume ratio of 1:4. After 6 hours, put the glass fiber mat and gel composite into a mixed solution containing he...
Embodiment 3
[0065] Place a 45m long, 1.5m wide, 10mm thick glass fiber mat in the form of a roll in a suitable container, take tetraethyl orthosilicate and deionized water and mix them uniformly at a volume ratio of 1:1 to obtain a silicon-containing solution. Add the silicon-containing solution, ethanol, and 1 mol / L sulfuric acid solution into the mixing tank at a volume ratio of 1:1:1 and mix evenly. After stirring for 30 minutes, pour the sol into the container where the glass fiber mat is placed, and keep it warm at 60°C for 6 hours. glue. After gelling, put the glass fiber mat and gel complex as a whole into the acid alcoholization solution, the amount of the acid alcoholization solution is at least less than the glass fiber mat and the gel complex as a whole, keep warm at 60°C, and the acid alcoholization solution is mixed with 40% sulfuric acid solution Prepare with absolute ethanol at a volume ratio of 1:4. After 6 hours, put the glass fiber mat and gel composite into a mixed solu...
