example 1
[0018] In terms of parts by weight, weigh 45 parts of N-methyl-2-pyrrolidone, 6 parts of polyethersulfone, 6 parts of chloroacetic acid and 1 part of aluminum chloride in a three-necked flask, and then heat treatment at 85 ° C for 2 hours After that, let it stand to cool to room temperature, filter the filter cake and rinse it with deionized water for 3 times, then vacuum freeze-dry to obtain modified polyethersulfone particles; Stir and mix the powder and place it in a quartz tube, place the quartz tube in a 950°C tubular atmosphere furnace, pass argon gas through the quartz tube, control the argon gas flow rate to 55mL / min, and then keep it warm under an argon atmosphere After reacting for 45 minutes, let it stand and cool to room temperature to obtain sedimentation-modified silica. According to the mass ratio of 1:1, mix cryolite and sedimentation-modification silica and place them in a ball mill jar, ball mill and pass through a 500-mesh sieve , to collect the mixed powder...

[0022] In terms of parts by weight, weigh 50 parts of N-methyl-2-pyrrolidone, 8 parts of polyethersulfone, 8 parts of chloroacetic acid and 2 parts of aluminum chloride and place them in a three-necked flask, then heat treatment at 5°C for 3 hours After that, let it stand to cool to room temperature, filter the filter cake and rinse it with deionized water for 5 times, and freeze-dry it in vacuum to obtain modified polyethersulfone particles; Stir and mix the powder and place it in a quartz tube, place the quartz tube in a tube-type atmosphere furnace at 1000°C, pass argon gas through the quartz tube, control the argon gas flow rate to 60mL / min, and then keep it warm under an argon atmosphere After reacting for 60 minutes, let it stand and cool to room temperature to obtain deposited modified silica. According to the mass ratio of 1:1, mix cryolite and deposited modified silica and put them in a ball mill jar, ball mill and pass through a 500-mesh sieve , to collect mixed powd...
