Embodiment 1
[0037]
[0038] Dissolve 30.00g of acrylamide in 94.00g of water, add 3.00g of the main crosslinking agent N,N-dimethylacrylamide and 0.52g of lithium magnesium silicate to the aqueous solution of acrylamide monomer in sequence, stir until clarified, then add 0.12 g of the secondary crosslinking agent polyethylene glycol diacrylate, mixed evenly to obtain a monomer solution; while uniformly stirring, nitrogen was passed through the polymerization system to remove oxygen for 30 minutes;
[0039] Take by weighing 0.06g potassium persulfate and dissolve in 6.00g water to prepare initiator solution;
[0040]Mix the monomer solution and the initiator solution, and put the mixed reaction solution in a water bath at 40°C for 10.0 hours, then raise the temperature to 60°C for 8.0 hours to increase the conversion rate;
[0041] The product obtained in the above steps was pulverized and dried in an oven at 60°C until constant weight;
[0042] Use a 12000r / min universal pulverizer to...
Embodiment 2
[0044]
