Embodiment 1
[0031] (1) Add 1000g of water, 30g of acrylamide and 50g of acrylic acid into the reactor, and fully stir at room temperature for 0.5 hours;
[0032] (2) Add a certain amount of potassium hydroxide solution with a concentration of 30.00%, adjust the neutralization degree of acrylic acid to 60-80%, and strictly control the temperature, not exceeding 40 o C;
[0033] (3) Add 800g lignite and stir well until the lignite is evenly dispersed in the solution;
[0034] (4) Add 2g of N,N'-methylenebisacrylamide and 2g of ammonium persulfate, and stir for 5-10 minutes;
[0035] (5) Raise the temperature of the reaction solution to 70-80 o C to react, strictly control the temperature, not more than 80 o c. React for 1-2h to stop the reaction when forming a viscous gel-like product;
[0036] (6) The product was taken out, cooled to room temperature, cut into small pieces, dried, and crushed with a pulverizer to obtain the high mechanical strength coal-based agricultural and forestry w...
