Embodiment 1
[0027] The ternary copolymerized cationic polyacrylamide provided in this example is prepared by the following steps:
[0028] (1) Prepare the cationic monomer E-AM, specifically: by mass percentage, weigh 25g (25%) of ETA (2,3-epoxypropyltrimethylammonium chloride), AM (monomer acrylamide ) 25g (25%), add 50mL (50%) of distilled water, stir to dissolve fully, put it in a water bath at 70°C for 2 hours, and cool down naturally to obtain the cationic monomer E-AM;
[0029] (2) Prepare monomer aqueous solution, specifically, by mass percentage, weigh AM (monomer acrylamide) 15g (15%), cationic monomer E-AM prepared in step (1) 5g (5%), DAC (acryloyloxyethyltrimethylammonium chloride) 5g (5%), add 75mL (75%) distilled water, stir evenly until completely dissolved, then the monomer with a mass concentration of 25% of the total monomer can be prepared aqueous solution;
