Embodiment 1
[0023] Weigh 37.5g, 80% (weight) of acrylic acid solution, put it into a beaker, add 25.4g of water into the beaker; weigh 11g of alkali, prepare it into a 30% (weight) solution, and pour it into the acrylic acid solution under stirring Slowly add the alkali solution dropwise, after the dropwise addition is completed, cool to room temperature in an ice-water bath; add 0.3g, 5% (weight) N,N-methylenebisacrylamide solution, and stir well; when the above system is heated to 75°C, Add 0.09 g of ammonium persulfate solution, stir evenly and further heat the system to 95° C., polymerize for 5 minutes to obtain a gel-like substance. After the polymerization is completed, the gel is cut into granules with a particle size of 1 cm, placed in an electric blast drying oven at 195°C for 2 hours to dry to constant weight, then crushed, sieved with 30-80 meshes, and finally Mix the surface cross-linking agent evenly, and dry it in an electric blast drying oven at 140°C for 45 minutes to obta...
Embodiment 2
[0025] Weigh 37.5g, 80% (weight) of acrylic acid solution, put it into a beaker, add 20.4g of water into the beaker; weigh 11g of alkali, prepare it into a 30% (weight) solution, and pour it into the acrylic acid solution under stirring Slowly add the alkali solution dropwise, after the addition is completed, cool to room temperature in an ice-water bath; add 5g, 8% (weight) of inorganic nanosheet water dispersion colloid; add 0.3g, 5% (weight) of N, N-methylenebis Acrylamide solution, stir evenly; when the above system is heated to 70°C, add 0.09g of ammonium persulfate solution, stir evenly, further heat the system to 95°C, and polymerize for 5 minutes to obtain a gel-like substance. After the polymerization is completed, the gel is cut into granules with a particle size of 1 cm, placed in an electric blast drying oven at 195°C for 2 hours to dry to constant weight, then crushed, sieved with 30-80 meshes, and finally Mix the surface cross-linking agent evenly, and dry it in ...
Embodiment 3
[0027] Weigh 37.5g, 80% (weight) of acrylic acid solution, put it into a beaker, add 14.4g of water into the beaker; weigh 11g of alkali, prepare it into a 30% (weight) solution, and pour it into the acrylic acid solution under stirring Slowly add the alkali solution dropwise, after the addition is completed, cool to room temperature in an ice-water bath; add 10g, 8% (weight) of inorganic nanosheet water dispersion colloid; add 0.3g, 5% (weight) of N, N-methylenebis Acrylamide solution, stir evenly; when the above system is heated to 75°C, add 0.09g of potassium persulfate solution, stir evenly, continue to heat the system to 90°C, and polymerize for 5 minutes to obtain a gel-like substance. After the polymerization is completed, the gel is cut into granules with a particle size of 1 cm, and placed in an electric blast drying oven at 100°C for 3 hours to dry to constant weight, then crushed, sieved with 30-80 mesh, and finally Mix the surface crosslinking agent evenly, and dry...
