Embodiment 1
[0025] 1) Place 3 parts of acrylic acid in an ice bath, neutralize with sodium hydroxide to obtain PH=6, then add 4 parts of acrylamide to form a monomer, and sequentially add persulfuric acid that accounts for 0.25% of the total monomer mass Potassium, N,N-methylenebisacrylamide accounting for 0.25% of the total monomer mass; raise the temperature of the water bath and react at 70°C for 7h, after the reaction product is cooled, filter out the reaction product and put it in a vacuum oven, in Dry to constant weight at 50°C to obtain salt-resistant superabsorbent resin;
[0026] 2) Weigh 4g of salt-resistant super absorbent resin and mix with 40ml of tap water, fully stir for about 10min and stand by;
[0027] 3) Weigh 10g of attapulgite and mix with 46ml of tap water, fully stir for 10-50min, and carry out the next reaction after the aggregate slurry is uniform;
[0028] 4) The two slurries obtained in step 2) and step 3) are fully mixed and stirred to obtain the result.

Embodiment 2
[0031] 1) Place 3 parts of acrylic acid in an ice bath, neutralize with sodium hydroxide to obtain PH=6, then add 4 parts of acrylamide to form a monomer, and sequentially add persulfuric acid that accounts for 0.25% of the total monomer mass Potassium, N,N-methylenebisacrylamide accounting for 0.25% of the total monomer mass; raise the temperature of the water bath and react at 70°C for 7h, after the reaction product is cooled, filter out the reaction product and put it in a vacuum oven, in Dry to constant weight at 50°C to obtain salt-resistant superabsorbent resin;
[0032] 2) Weigh 2g of salt-resistant super absorbent resin and mix with 30ml of tap water, and fully stir for about 10min for use;
[0033] 3) Weigh 15g of attapulgite and mix with 53ml of tap water, fully stir for 10-50min, and proceed to the next step after the aggregate slurry is uniform;
[0034] 4) The two kinds of slurries obtained in step 2) and step 3) are fully mixed and uniformly stirred to obtain th...
