Insertion plural gel granule and synthetic method thereof

The invention relates to a plural gel granule obtained by adopting an intercalation technology and a synthetic method thereof. The technical scheme is as follows: the plural gel granule (abbreviated as DMJK) is obtained by inserting a cation hydrophobic monomer into a clay interlayer and then adding the monomer for insertion and polymerization. The synthetic method comprises the following steps of: adding 100 mL of ethanol to 20 mL of bromohexadecane and 11 mL of methacrylic acid-2-dimethylamino ethyl ester, reacting under the condition of 50 DEG C for 24 hours, removing ethanol, extracting by using acetone, and drying under the condition of 50 DEG C for 24 hours to obtain the hydrophobic monomer DMJ; and adding 12 g of bentonite to 30 mL of water, swelling, adding 0.3 g of DMJ, stirring at room temperature for 24 hours, adding 12 g of acrylamide and 30 mg of N,N-methylene bisacrylamide, stirring for 15 minutes, dissolving, then adding 90 mg of ammonium persulfate, and reacting under the condition of 50 DEG C
