Embodiment 1
[0020] 5 grams of acrylonitrile, 0.36 grams of sodium lauryl sulfate, 0.36 grams of OP-10, 0.15 grams of sodium metabisulfite, 0.24 grams of anhydrous sodium acetate, 0.15 grams of glacial acetic acid, 0.03 grams of EDTA, 200 grams of water, 0.15 grams of montmorillonite Soil, 0.15 g of silicon dioxide was added to a 500 ml four-neck flask, stirred thoroughly, and then ultrasonically oscillated for 30 minutes, and then the reactor was heated to 60° C. under magnetic stirring. After reaching the reaction temperature, 25 grams of acrylonitrile and an initiator solution (0.3 grams of ammonium persulfate, 16 grams of water) were evenly fed through a constant pressure funnel. After 5 hours of reaction, the material was discharged to obtain a white emulsion. After the emulsion is demulsified with a saturated sodium chloride solution, it is washed, dehydrated and dried to obtain a polyacrylonitrile nanocomposite material. The reaction conversion rate is 77.30%, the temperature for 2...
Embodiment 2
[0022] 5 grams of acrylonitrile, 0.36 grams of sodium lauryl sulfate, 0.36 grams of OP-10, 0.15 grams of sodium metabisulfite, 0.24 grams of anhydrous sodium acetate, 0.15 grams of glacial acetic acid, 0.03 grams of EDTA, 200 grams of water, 0.3 grams of Mongolian To remove the soil, add 0.3 g of silicon dioxide into a 500 ml four-neck flask, stir well, then oscillate ultrasonically for 30 minutes, and then the reactor is heated to 60° C. under magnetic stirring. After reaching the reaction temperature, 25 grams of acrylonitrile and an initiator solution (0.3 grams of ammonium persulfate, 16 grams of water) were evenly fed through a constant pressure funnel. After 5 hours of reaction, the material was discharged to obtain a white emulsion. After the emulsion is demulsified with a saturated sodium chloride solution, it is washed, dehydrated and dried to obtain a polyacrylonitrile nanocomposite material. The reaction conversion rate is 66.38%, the temperature for 20% degradatio...
